TUBULAR STRUCTURE BASED ON HYALURONIC ACID DERIVATIVES FOR THE PREPARATION OF VASCULAR AND URETHRAL GRAFT

摘要

Tubular structure, whose wall has an unbroken surface consisting essentially of at least one HA derivative and optionally a further polymer of natural, synthetic or semisynthetic origin. Said tubular structure, which is prepared with a very simple process, is used for the preparation of vascular and urethral grafts.
