Technical Considerations for Non-Clinical Assessment of Medical 
Devices Containing Nitinol; Guidance for Industry and Food and Drug 
Administration Staff; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing 
the availability of a final guidance entitled ``Technical 
Considerations for Non-Clinical Assessment of Medical Devices 
containing Nitinol.'' The Agency has developed this guidance to provide 
FDA's current thinking on technical considerations specific to devices 
using nitinol due to the unique properties of nitinol. This guidance 
document is intended to provide clarity and consistency in recommended 
non-clinical assessments across a variety of medical devices that 
contain nitinol.

DATES: The announcement of the guidance is published in the Federal 
Register on October 15, 2020.

SUPPLEMENTARY INFORMATION:

I. Background

    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

[[Page 65410]]

the 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    A notice of availability of the draft guidance appeared in the 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.

II. Electronic Access

    Persons interested in obtaining a copy of the guidance may do so by 
downloading an electronic copy from the internet. A search capability
