Title:
VASCULAR ANASTOMOTIC MEMBER COMPRISING SHAPE-MEMORY POLYMER
Document Type and Number:
WIPO Patent Application WO/2020/071806
Kind Code:
A1
Abstract:
The present invention relates to an artificial blood vessel comprising a shape-memory polymer, and a vascular anastomotic member formed of a shape-memory polymer. An artificial blood vessel according to an embodiment of the present invention comprises a shape-memory polymer including photo-crosslinkable functional groups, the artificial blood vessel thus provided having a fusion point suitable for in vivo transplantation. Also, provided is a vascular anastomotic member which comprises a shape-memory polymer including photo-crosslinkable functional groups, and thus has a fusion point suitable for in vivo transplantation.
