Significance and Use

4.1 A common therapy to mitigate the pathological effects of blood vessel occlusion or aneurysm-related vascular wall weakening is to reroute blood flow around the diseased vascular regions. Autologous and non-autologous grafts are often used as vascular substitutes surgically to achieve this therapeutic intervention. Vascular graft TEMPs may also be used for these purposes. They may also be used to create or revise arteriovenous shunts.

4.2 Coronary, carotid, renal, common iliac, external iliac, superficial femoral, and popliteal arteries are examples of vascular sites commonly requiring bypass surgery.

4.3 TEMPs may be composed of biological products (for example, cells, organs, and tissues), biomaterials (for example, substrates and scaffolds composed of polymers or collagen), biomolecules (for example, recombinant proteins, native/biological proteins, amino acids, peptides, fatty acids, sugars and other macromolecules) and various combinations thereof (see Terminology F2312). Examples of TEMPs are listed in Classification F2211.

4.4 TEMPs may be used with the intent of facilitating the surgical outcome by improving the biological repair and/or reconstruction, by accommodating the mechanical loads at the repair site, or by a combination of these mechanisms.

4.5 Clinical evidence of improved surgical outcomes may include patency, reduced incidence of revision surgery, reduced rate of implant infection, and improved functionality after surgery.

Scope

1.1 This guide is intended as a resource for individuals and organizations involved in the development, production, delivery, and regulation of tissue engineered medical products (TEMPs) intended for use in the surgical repair, replacement, shunting and/or bypass of blood vessels. This guide is intended for use related to the in vitro assessment of TEMP vascular grafts. In vitro cellular characterization and in vivo testing are not within scope for this standard guide.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
