<P>PROBLEM TO BE SOLVED: To provide an implantable material comprising a biocompatible matrix and cells which, when provided to a vascular access structure, can promote functionality generally. <P>SOLUTION: The implantable material 22 can enhance maturation of an arteriovenous native fistula as well as prolong the fistula in a mature, functional state suitable for dialysis. Additionally, the implantable material can promote formation of a functional arteriovenous graft suitable for dialysis as well as promote formation of a functional peripheral bypass graft. The implantable material can be configured as a flexible planar form or a flowable composition with shape retaining properties suitable for implantation at, adjacent or in the vicinity of an anastomoses or arteriovenous graft using the anastomoses 114 or the arteriovenous graft. The implantable material is provided to an exterior surface of a blood vessel 100. Certain embodiments of the flexible planar form define a slot. <P>COPYRIGHT: (C)2012,JPO&INPIT |
