SUPPLEMENTARY INFORMATION:

I. Background and Objectives

    While the majority of cardiovascular implants are made of metals 
and may be susceptible to corrosion, it is unclear whether the current 
corrosion testing paradigm is predictive of in vivo corrosion outcomes, 
or if there may be more suitable assessments to predict corrosion 
failure. In addition, there has been an increase in the use of nitinol, 
a nickel-titanium alloy, in cardiovascular implants due to its 
superelastic properties, which are ideal for transcatheter-delivered 
therapies. Corrosion of implant devices made of nitinol and other 
nickel-containing metal alloys (e.g. stainless steel, MP35N) results in 
the release of nickel ions,

[[Page 5815]]

which may lead to various modes of toxicities. Furthermore, both nickel 
ion release and corrosion characteristics are dependent on surface 
finishing for nitinol as well as for some other nickel-containing 
alloys. Through the collection of information from a pre-workshop work 
assignment and discussions with workshop participants, FDA will be able 
to better determine what assessments may be considered for 
cardiovascular implants made of commonly used metallic alloys, and this 
information is expected to serve as the foundation for a future 
guidance document.

II. Topics for Discussion at the Public Workshop

    The objective of this workshop is to provide a forum for discussion 
of the following topics:
     The various methods that are used for corrosion 
assessments, surface characterization techniques, and nickel leach 
testing used to evaluate the suitability of metallic cardiovascular 
implant devices;
     The limitations of each of these tests to predict actual 
in vivo performance;
     The need and utility for each test; and
     The potential testing paradigms, including when certain 
tests should be considered, and how to establish acceptance criteria 
for each test.

III. Transcripts

    Please be advised that as soon as a transcript is available, it 
will be accessible at https://www.regulations.gov. It may be viewed at 
the Division of Dockets Management (HFA-305), Food and Drug

transcript will also be available in either hardcopy or on CD-ROM, 
after submission of a Freedom of Information request. Written requests 
are to be sent to the Division of Freedom of Information (ELEM-1029),
