Start Supplemental Information
The use of nitinol in medical devices began over three decades ago in product areas such as orthodontic archwires, cardiovascular guidewires, and surgical instruments. Its use has increased over the past two decades into different device areas such as orthopaedic fracture fixation, coronary stents, and transcatheter heart valves. With an increasing trend to treat patients using minimally invasive procedures, nitinol has become a popular choice of material due to its ability to return to its original shape after being mechanically deformed or after heat is applied. Given Start Printed Page 65410the complex thermomechanical behavior of nitinol, there are unique considerations when assessing the safety and performance of nitinol devices.
The Agency has developed this guidance to provide FDA's current thinking on technical considerations specific to devices using nitinol. These recommendations are intended to be general and apply to medical devices that have at least one patient contacting component comprised of nitinol. The following technical areas are covered by this guidance: general information, mechanical testing, corrosion, biocompatibility, and labeling of nitinol devices.
A notice of availability of the draft guidance appeared in the Federal Register of April 19, 2019 (84 FR 16516). FDA considered comments received and revised the guidance as appropriate in response to the comments, including minor technical clarifications.
This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the current thinking of FDA on technical considerations for non-clinical assessment of medical devices containing nitinol. It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.
