Question 1

How can a law firm find a medical devices expert witness for litigation?

Accepted Answer

A law firm can find a medical devices expert witness for litigation by filtering candidates by device type, engineering or clinical background, and specific medical device litigation experience. Counsel should review curricula vitae, FDA and industry experience, prior product liability and device failure testimony, publication history, and familiarity with Daubert and Rule 702 standards. Effective search criteria include experience with the relevant implant or instrument, knowledge of FDA regulations and 510(k) or Premarket Approval submissions, and a history of clear written reports and deposition testimony.

Question 2

What does a medical devices expert witness do in product liability and device failure cases?

Accepted Answer

A medical devices expert witness in product liability and device failure cases analyzes the design, materials, manufacturing processes, labeling, and instructions for use of the device. The expert conducts failure analysis and forensic investigation, reviews quality system records, testing data, complaint files, Medical Device Reporting data, and recall information. The expert then prepares reports that address causation, defect, and regulatory compliance, and provides expert testimony in deposition and at trial to explain whether the medical device performance met applicable engineering, clinical, and regulatory standards.

Question 3

Which types of medical device litigation cases commonly require expert testimony?

Accepted Answer

Medical device litigation cases that commonly require expert testimony include claims involving orthopedic and cardiac implants, infusion pumps, diagnostic and monitoring equipment, in vitro diagnostic devices, and surgical instruments. Cases alleging design defect, manufacturing defect, failure to warn, or device malfunction routinely use medical device failure experts. Class actions, wrongful death lawsuits, device recall litigation, and cases involving alleged violations of FDA regulations or Medical Device Reporting obligations also frequently require medical devices expert witness testimony.

Question 4

What qualifications should a medical device regulatory compliance expert witness have?

Accepted Answer

A medical device regulatory compliance expert witness should have formal training in biomedical engineering, mechanical engineering, or a medical discipline, along with substantial experience in the medical device industry. Relevant background includes responsibility for quality systems, regulatory affairs, or clinical affairs under U.S. Food and Drug Administration regulations and ISO 13485 standards. Preferred credentials may include Regulatory Affairs Certification, quality or auditing certifications, authorship of regulatory submissions such as 510(k) or Premarket Approval applications, and prior experience preparing expert reports and testimony in medical device regulatory compliance disputes.

Question 5

How does an expert witness review FDA regulations, 510(k) clearance, and MDR requirements in a medical device case?

Accepted Answer

In a medical device case, an expert witness reviews FDA regulations, 510(k) clearance, and Medical Device Reporting requirements by comparing the device manufacturer’s actions to the applicable statutory and regulatory standards. The expert examines 510(k) or Premarket Approval files, labeling, risk management documents, design history files, and quality system records. The expert then assesses whether the device classification, indications for use, adverse event reporting, and corrective actions complied with 21 CFR Part 820 and Medical Device Reporting rules, and explains any deviations in an expert report and testimony.

Question 6

How do medical device experts conduct failure analysis and forensic investigation on a device?

Accepted Answer

Medical device experts conduct failure analysis and forensic investigation by preserving the device, documenting its condition, and following chain of custody procedures. The expert may perform visual and microscopic inspection, mechanical testing, materials and metallurgical analysis, and software or firmware review when applicable. Testing is typically performed under relevant ASTM and ISO standards. The expert correlates test data with clinical records, imaging, and operative reports to determine how and why the device failed and whether the failure was due to design, manufacturing, misuse, or maintenance issues.

Question 7

What is the role of a medical device expert witness in patent litigation and intellectual property disputes?

Accepted Answer

In patent litigation and intellectual property disputes, a medical device expert witness analyzes device design and function in relation to asserted patent claims. The expert compares claim elements to the accused product, evaluates prior art, and assesses issues such as infringement, validity, and obviousness. The expert prepares detailed claim charts, supports counsel in Markman hearings, and provides deposition and trial testimony that explains complex engineering and medical concepts to the court in a clear and technically accurate manner.

Question 8

What factors affect the cost of hiring a medical devices expert witness?

Accepted Answer

The cost of hiring a medical devices expert witness depends on the expert’s credentials, specialty, and prior testimony experience, as well as the complexity and timeline of the case. Common cost components include hourly rates for review and consultation, flat or minimum fees for written reports, separate rates for deposition and trial testimony, travel expenses, and laboratory or testing costs. Early scoping of the expected work and a clear engagement letter help counsel manage expert witness fees in medical device litigation.

Question 9

How should attorneys vet and retain a medical devices expert witness early in a case?

Accepted Answer

Attorneys should vet and retain a medical devices expert witness early in a case by identifying the specific device, alleged failure mode, and governing regulatory framework, then matching those needs to the expert’s background. Counsel should review the expert’s curriculum vitae, clinical or engineering experience, FDA and quality system responsibilities, publication history, and prior deposition and trial testimony. Conflict checks, reference checks, and a discussion of Daubert or Rule 702 challenges are essential. A written retention agreement should define scope, confidentiality, deadlines, and fee structure for the medical device case expert.
