Defective Medical Products Claims

What Is a Defective Medical Product Claim?

A defective medical product claim may arise where a medical product, device, medicine or item of equipment does not perform as safely as a patient would reasonably expect, and the patient is alleged to have suffered harm as a result.

These claims can involve a wide range of products used in hospitals, clinics, pharmacies and GP practices across Ireland.

Defective medical devices and implants

Medical devices and implants that may be the subject of a claim include:

• Hip and knee implants: Replacement joints that fail prematurely, loosen or cause tissue damage.
• Orthopaedic implants: Plates, screws, rods or fixation devices used in bone and joint surgery.
• Heart valves: Mechanical or biological valves that malfunction or deteriorate earlier than expected.
• Pacemakers: Devices that fail to regulate heart rhythm or develop electrical or software faults.
• Prostheses: Artificial limbs or body parts that do not meet expected safety standards.
• Surgical mesh: Mesh products used in hernia repair or pelvic floor surgery that cause complications.
• Contraceptive devices: Intrauterine devices or implants linked with injury or unintended failure.
• Catheters and implanted systems: Devices placed inside the body for drainage, medication delivery or monitoring.

Defective medicines and pharmaceutical products

Claims involving medicines may arise where:

• Warnings were insufficient or absent: The patient was not adequately informed of known risks or side effects.
• The product was contaminated or incorrectly manufactured: Errors during production led to an unsafe product reaching the patient.
• Serious adverse effects were linked to the product: The medicine caused harm that was disproportionate to its intended benefit.
• Prescription or administration issues arose: In some cases, the way a medicine was prescribed or given may also raise questions of medical negligence.

Defective surgical instruments and hospital equipment

Claims may also involve:

• Faulty surgical instruments: Tools that break, malfunction or perform unpredictably during a procedure.
• Monitoring equipment: Devices used to track a patient's vital signs that give inaccurate readings or fail.
• Diagnostic equipment: Scanners, imaging devices or testing machines that produce unreliable results.
• Equipment that fails during treatment or surgery: Any device or system that stops working at a critical moment.

Common Types of Defects in Medical Product Claims

Not every medical product that causes harm is necessarily defective. The law looks at whether the product meets the level of safety that a person is entitled to expect. Defects generally fall into several categories.

Design defects

A product may be unsafe because of the way it was designed, even if every unit was manufactured exactly as intended. If the design itself creates an unreasonable risk, all products of that type may be affected.

Manufacturing defects

These arise where something goes wrong during production. This could include batch errors, contamination, material faults, component failure or poor assembly. The product may differ from what the manufacturer intended to produce.

Inadequate warnings or instructions

A product may be considered defective where the warnings, instructions, contraindications or risk information provided with it were not adequate. Patients and healthcare professionals rely on this information to make informed decisions.

Failure to monitor, recall or communicate known risks

Where a manufacturer or supplier becomes aware of a safety concern, there may be an obligation to act. Product recalls, safety notices and regulatory communications may become relevant evidence in a claim. However, a recall does not automatically prove liability in every case; the full facts still need to be assessed.

Defective Medical Products and Irish Product Liability Law

Irish law provides several possible routes for bringing a defective medical product claim. The appropriate legal basis depends on the facts of each case and may involve statute, negligence, breach of duty, medical negligence or a combination of these.

Liability under the Liability for Defective Products Act 1991

The Liability for Defective Products Act 1991 introduced a product liability framework in Ireland. The Department of Enterprise notes that the Act gives effect to Directive 85/374/EEC and introduces the principle of strict or no-fault liability into Irish law.

This means that in certain circumstances, a producer may be held liable for damage caused by a defective product without the injured person having to prove negligence. The Act supplements existing remedies in tort and contract law, rather than replacing them.

Product liability vs medical negligence

It is important to understand the distinction between product liability and medical negligence, as they involve different questions:

• Product liability may focus on the manufacturer, producer, importer, supplier or the defect in the product itself.
• Medical negligence may focus on the selection, implantation, prescription, administration, aftercare, monitoring or warnings given by healthcare professionals.

Some cases may involve both. For example, a patient may have received a defective implant (product liability) that was also implanted using a technique that fell below the expected standard of care (medical negligence).

Who may be responsible?

Depending on the facts, the following parties may need to be investigated:

• Manufacturer or producer: The company that designed and made the product.
• Importer: The party that brought the product into the Irish or EU market.
• Supplier or distributor: The entity that supplied the product to the hospital, pharmacy or clinic.
• Hospital or clinic: The facility where the product was used or administered.
• Treating consultant or medical team: The professionals who selected, implanted, prescribed or monitored the product.
• Pharmacist or prescribing professional: Depending on the issue, the person who dispensed or prescribed the product.

Examples of Defective Medical Product Claims Michael Boylan Litigation Can Advise On

Michael Boylan Litigation has experience advising on a broad range of defective medical product matters. The following are examples of the types of claims the firm handles.

Defective hip replacement and orthopaedic implant claims

The firm is currently representing a large number of clients in claims relating to DePuy's ASR hip replacement product. In August 2010, DePuy Orthopaedics recalled the ASR XL Acetabular System and the ASR Hip Resurfacing System from the market in Ireland. Michael Boylan Litigation has issued proceedings on behalf of numerous people affected by these products, seeking compensation for their pain, suffering and loss.

Orthopaedic implant claims may also involve knee replacements, spinal fixation devices, plates and screws or other joint components that fail, loosen or cause tissue reactions.

Heart valve and pacemaker claims

These claims may involve device failure, early deterioration, defective components, a lack of adequate warnings or the need for revision surgery. Where a cardiac device does not function as expected, the consequences can be significant.

Surgical mesh and implant-related injuries

Surgical mesh claims have become increasingly common in Ireland and internationally. Patients may experience pain, infection, migration of the mesh, erosion into surrounding tissue, further surgery and long-term complications. These claims require careful investigation of both the product and the surgical technique used.

Defective medicine and drug-related injury claims

These claims may involve warning failures, serious adverse effects, contaminated products or unsafe medicines. In some cases, issues relating to how a medicine was prescribed or monitored may overlap with medical negligence.

Retained or defective surgical items

It is important to distinguish between a defective product claim and a surgical negligence claim. If a surgical instrument broke because of a manufacturing fault, this may be a product liability matter. If a product or item was left inside the body, misused or not properly removed due to a failure in the standard of care, the claim may be one of surgical negligence rather than product defect.

Notable cases

Michael Boylan Litigation's track record in this area includes:

• Injury caused by wire mesh implants.
• Legal action commenced on behalf of individuals affected by a narcolepsy link to the Pandemrix swine flu vaccination. The firm helped form a new European alliance on behalf of children and adults injured as a result of the Human Swine Flu vaccine, Pandemrix.
• Michael Boylan addressed the International Narcolepsy Conference in Stockholm on behalf of Irish patients diagnosed following swine flu vaccination.
• €200,000 settlement on behalf of a Roscommon man following a failure to diagnose a fault in a knee prosthesis.
• DePuy hip recall litigation.
• Narcolepsy litigation.
• Early settlements in three medical negligence actions.

What Must Be Investigated in a Defective Medical Product Claim?

A successful claim requires careful investigation of several issues. The following are the main areas that typically need to be examined.

Whether the product was defective

Expert evidence may be needed to assess whether the product failed to meet the expected level of safety. This could involve examining the product itself, its design, its manufacturing history or its regulatory approvals.

Whether the defect caused the injury

It is not enough to show that the product was defective. The investigation must also establish that the defect caused or materially contributed to the injury. This is known as causation and is often one of the most closely examined issues in these claims.

The nature and extent of the injury

The injured person's medical records, symptoms, corrective treatment, ongoing care needs, impact on work and long-term prognosis will all be relevant. This evidence helps to establish both the nature and the value of the claim.

Whether the product was recalled or subject to safety warnings

Recall letters, manufacturer notices, HPRA communications, hospital letters or consultant advice may all be relevant. These documents can help to establish what was known about the product's safety and when.

Evidence That May Be Important in a Defective Medical Products Claim

Gathering the right evidence early can make a significant difference to the strength of a claim. The following types of records and documents are often relevant.

Medical and hospital records

• GP records: Notes from your general practitioner, including referrals and prescriptions.
• Hospital charts: Admission, treatment and observation records.
• Consultant notes: Specialist assessments and opinions.
• Operation notes: Detailed records of the surgical procedure.
• Discharge summaries: Records of your condition on leaving hospital.
• Radiology and scan reports: X-rays, MRI scans, CT scans and ultrasound results.
• Blood test results: Laboratory findings that may be relevant to the injury or its cause.
• Follow-up clinic letters: Correspondence about post-operative reviews and ongoing care.

Product information and documentation

• Implant stickers: Labels placed in your medical records identifying the specific product used.
• Device serial numbers: Unique identifiers for the individual product.
• Batch or lot numbers: Numbers that identify the production run.
• Product leaflets: Information provided with the product about its use, risks and warnings.
• Recall letters: Any correspondence from manufacturers, hospitals or the HPRA about product safety.
• Pharmacy records: Dispensing records for medicines or pharmaceutical products.
• Prescription records: Details of what was prescribed and by whom.
• Packaging, where available: Original packaging or labelling that may contain relevant information.

Expert medical and technical reports

These claims often require input from medical specialists and, where appropriate, technical or engineering experts. Expert reports help to establish whether the product was defective, whether the defect caused the injury, and what the long-term effects are likely to be.

Time Limits for Defective Medical Product Claims in Ireland

There are strict time limits for bringing defective medical product claims in Ireland. Missing these deadlines can mean losing the right to pursue a claim entirely.

The three-year period under defective product legislation

Under section 7 of the Liability for Defective Products Act 1991, an action under the Act generally cannot be brought after three years from the date the cause of action accrued or, if later, the date the injured person became aware, or should reasonably have become aware, of the damage, the defect and the identity of the producer.

There is also an absolute ten-year cut-off from the date the producer put the product into circulation, after which the right of action is extinguished.

Date of knowledge in medical product cases

Patients may not immediately know that a medical product was defective. Problems may emerge months or years later through symptoms, the need for revision surgery, scan results, testing, recall letters or specialist advice. The date of knowledge, not necessarily the date of the procedure, is what matters for limitation purposes.

Why early advice may be important

Because time limits can be fact-specific, early legal advice may help clarify what dates are relevant and what records should be preserved. This is particularly important in cases where the patient only discovers the problem some time after the product was implanted or prescribed.

What to Do if You Are Concerned About a Defective Medical Product

If you believe you may have been harmed by a defective medical product, there are several practical steps worth considering.

• Seek medical advice first: Your health should always come first. If you are experiencing symptoms or complications, speak to your GP, consultant or another appropriate medical professional as soon as possible.
• Keep documents and product information: Preserve any letters, product cards, medication packaging, appointment letters, scans and emails you have received. These documents may be needed later.
• Make a written timeline: Record when the product was implanted, prescribed or used, when symptoms began, who you contacted and what treatment followed. A clear timeline can be very helpful during a legal review.
• Avoid disposing of relevant product materials: Where it is safe to do so, keep any packaging, device cards or product documentation you may have. These materials may assist a later investigation into the product.

Frequently Asked Questions About Defective Medical Products Claims

What is a defective medical product claim?

A defective medical product claim is a legal action brought by a patient who has been harmed by a medical product that did not perform as safely as expected. The claim may seek compensation for pain, suffering, medical expenses, loss of earnings and other losses.

Is a defective medical product claim the same as a medical negligence claim?

Not always. A product liability claim focuses on the product itself, while a medical negligence claim focuses on the standard of care provided by healthcare professionals. In some cases, both may apply. For example, a defective implant may have also been implanted negligently.

Can a recalled medical device lead to a claim?

A product recall may be relevant evidence, but it does not automatically prove that every patient who received the product has a valid claim. The facts of each case still need to be investigated, including whether the product was actually defective and whether the defect caused the injury.

Who can be responsible for a defective medical device?

Depending on the circumstances, the manufacturer, importer, supplier, hospital, treating consultant or another party may be responsible. In many cases, more than one party may be involved.

What evidence should I keep?

Keep all medical records, letters from hospitals or consultants, product identification cards or stickers, prescription records, medication packaging and a written timeline of your symptoms and treatment. The more documentation you preserve, the easier it may be to investigate your claim.

How long do I have to bring a defective medical product claim in Ireland?

Under the Liability for Defective Products Act 1991, the general time limit is three years from the date you became aware, or should reasonably have become aware, of the damage, the defect and the identity of the producer. There is also an absolute ten-year limit from the date the product was put into circulation. Because these deadlines are fact-specific, it is advisable to seek legal advice on your particular circumstances.

Can I bring a claim if the product was implanted years ago?

It may still be possible, depending on when you first became aware of the defect and the injury. The date of knowledge rather than the date of the procedure is what determines when time begins to run. Legal advice should be sought to assess whether your claim falls within the relevant limitation period.

What if the medical product was safe but used incorrectly?

If the product itself was not defective but was used, implanted or prescribed incorrectly, the claim may fall closer to medical negligence than product liability. The distinction depends on whether the harm was caused by the product or by the way it was used.

Do I need an expert report?

In most cases, yes. Defective medical product claims are complex and typically require expert medical evidence and, in some cases, technical or engineering reports. These reports help to establish whether the product was defective, whether the defect caused the injury, and what the long-term effects are likely to be.
