Abstract
An implantable medical device, and a method of manufacturing the same, the device including a bioresorbable conduit including an exterior surface including one or more weakened areas configured to degrade preferentially to the remainder of the bioresorbable conduit, and an interior surface.
Claims20
An implantable medical device comprising:
- a bioresorbable conduit comprising:
- an exterior surface comprising one or more weakened areas configured to degrade preferentially to a remainder of the bioresorbable conduit;
- and
- an interior surface.
1 more element
A method of manufacturing an implantable medical device, the method comprising:
- providing a bioresorbable conduit comprising an exterior surface and an interior surface;
- and
- weakening one or more areas of the exterior surface of the bioresorbable conduit, such that the one or more weakened areas of the exterior surface degrade preferentially to a remainder of the bioresorbable conduit.
An implantable medical device comprising:
- a first surface comprising one or more weakened areas configured to degrade preferentially to a remainder of the first surface;
- and
- a second surface,
- wherein an area of the first surface has a different density and/or degree of weakening of one or more weakened areas than another area of the first surface.
