SUPPLEMENTARY INFORMATION:

I. Background

Nanomaterials, measured in nanometers (a billionth of a meter), often possess physical and chemical properties that are different from their larger counterparts. Due to the high surface area to volume ratio, the small size, and the type of nanoscale material, these materials may exhibit altered magnetic, electrical, optical properties and altered chemical and biological activities. These characteristics provide the potential for nanomaterials to be used in a variety of medical device applications. However, some of these nanomaterial properties may also present safety concerns that are not found in their larger counterparts. The use of nanotechnology is increasingly applicable and provides novel opportunities in medical device development. The scientific hurdles (e.g., biocompatibility and toxicity) for safe use of nanomaterials in medical devices, including the processes and standards for their manufacture and characterization, are not understood.

In July 2007, FDA's Nanotechnology Task Force issued a report describing the state of the science and regulatory challenges in translating nanotechnology into FDA-regulated products (available at http://www.fda.gov/​ScienceResearch/​SpecialTopics/​Nanotechnology/​NanotechnologyTaskForceReport2007/​default.htm). A general finding of the report is that nanoscale materials Start Printed Page 51830present regulatory challenges similar to those posed by products using other emerging technologies and that these challenges may be magnified because nanotechnology can be used in, or used to make, any FDA-regulated product. In addition, the properties of a material with features in the nanoscale range might change, impacting the safety and effectiveness of the FDA-regulated products.

The objective of this public workshop is to obtain information on manufacturing, characterization, and evaluation of biocompatibility of medical devices containing or utilizing nanomaterials and nanostructures.

II. Public Participation

There are two types of opportunities for participation planned for the public workshop: Time limited oral presentations and round-table discussions.

If you wish to make an oral presentation during the public workshop, you must indicate this at the time of registration. The number of presentations may be limited based on the number of requests received during the public comment period. When registering, you will be required to identify the title of the topic you wish to address in your presentation and answer all the related questions on the registration form at http://www.fda.gov/​MedicalDevices/​NewsEvents/​WorkshopsConferences/​default.htm. FDA will do its best to accommodate requests to present and will focus discussion to the topics described in this document (see section III of this document). Individuals and organizations with common interests are urged to consolidate or coordinate their presentations, and to request time for joint presentations. FDA will determine the amount of time allotted to each presenter and the approximate time that each oral presentation is to begin.

To close each of the two sessions, FDA will hold a round-table discussion between FDA staff and selected participants representing a range of constituencies. If you wish to be a participant in round-table discussions, you must indicate this interest at the time of registration, and also submit a brief statement that describes your experience or expertise with nanotechnology. FDA will attempt to have a range of constituencies represented in this discussion group. Others in attendance at the workshop will have an opportunity to listen during each round-table discussion and provide public comments, time permitting. FDA will determine the participants based on the requests received. The participants in each round-table discussion will remark on the presentations given during the session, engage in a dialogue with each other and FDA staff, and provide closing thoughts on the session. Round-table participants will not be asked to develop consensus opinions during the discussion, but rather to provide their individual perspectives.

III. Issues for Discussion

The workshop will focus on two topics: (1) Manufacturing and characterization of medical devices containing or utilizing nanomaterials or nanostructures; (2) biocompatibility evaluation of medical devices containing or utilizing nanomaterials or nanostructures. The discussion on manufacturing and characterization will include the evaluation of physico-chemical properties of nanomaterials or nanostructures, characterization methods required, device manufacturing processes and evaluation of the final processed device after sterilization, and stability and aging studies. The discussion on biocompatibility evaluation will include testing for potential release of nanomaterials and additional testing considerations other than standard testing methods to determine the biocompatibility and toxicity of devices containing or utilizing nanomaterials or structures. For further information, please refer to the meeting registration Web page at http://www.fda.gov/​MedicalDevices/​NewsEvents/​WorkshopsConferences/​default.htm.
