Abstract
The present invention provides apparatus and methods for a conduit, such as an implantable conduit for a vessel. The conduit may comprise a main member and a side-branch member. The conduit may be implanted with the side-branch member initially disposed within the main member. When positioned, the side-branch member may then be extended from within the main member and into a vessel side-branch. The materials for the conduit may include circumferentially distensible and/or low recoil materials. The materials for the conduit may be constructed by various techniques and may include materials with enhanced flexibility and kink resistance.
Claims12
A conduit, comprising:
- a frameless film-tube construct formed by wrapping and bonding together a plurality of layers of material, wherein the plurality of layers of material includes at least one layer of a microporous polyethylene film, and wherein the film-tube construct is longitudinally compressed from a first axial length to a second axial length that is shorter than the first axial length such that at least a portion of an exteriorly facing surface of the film-tube construct exhibits corrugations with the corrugations providing the film-tube construct with enhanced flexibility and kink resistant characteristics.
