Abstract

The present disclosure provides medical devices, systems and methods and in particular to devices and methods useful for anchoring graft materials to bodily structures.

First claim

The invention claimed is:

1. A vascular graft comprising:
at least one conduit having a first conduit region and a second conduit region, wherein the first conduit region has a substantially constant diameter and is connected to a first end of the second conduit region and a second end of the second conduit region contains an opening configured to connect to a vessel and wherein a portion of the first conduit region extends into the second conduit region;
wherein the second conduit region is a connector having an enlarged portion and a connector portion, the enlarged portion configured such that the first conduit region swivels within the enlarged portion without touching an interior portion of the enlarged portion.

2. The vascular graft according to claim 1 , wherein the first conduit region includes a first material and the second conduit region includes a second material distinct from the first material.

3. The vascular graft according to claim 2 , wherein the first material includes silicone rubber.

4. The vascular graft according to claim 2 , wherein the second material includes porous ePTFE.

5. The vascular graft according to claim 2 wherein the second material includes woven Dacron.

6. The vascular graft according to claim 1 , wherein the at least one conduit is configured to couple to a blood flow assist system.
