Abstract

An attachment system for attaching an intravascular device to a vessel wall of a body vessel is disclosed. The attachment system includes an intravascular device and biological attachment material connected to the intravascular device. The biological attachment material is configured to attach the intravascular device to the vessel wall.

Claims

1. An intravascular device attachment system for attaching an intravascular device to a vessel wall, the system comprising:

an intravascular device; and

biological attachment material connected to the intravascular device, the biological attachment material being configured to attach the intravascular device to the vessel wall.

2. The intravascular device attachment system of claim 1, wherein the biological attachment material comprises small intestinal submucosa (SIS).

3. The intravascular device attachment system of claim 1, further comprising a plurality of barbs configured to anchor the intravascular device to the vessel wall.

4. The intravascular device attachment system of claim 1, wherein the intravascular device is one of a cardiac assist device, a valve, a drug eluting device, and a sensor.

5. The intravascular device attachment system of claim 4, wherein the intravascular device is a cardiac assist device for assisting with blood circulation, the cardiac assist device having a pump and a pump housing.

6. The intravascular device attachment system of claim 4, wherein the intravascular device comprises a retrieval member configured to be grasped to retrieve the intravascular device.

7. The intravascular device attachment system of claim 6, wherein the retrieval member is one of a tether, an electrical conduit, and a drug delivery channel.

8. The intravascular device attachment system of claim 3, the intravascular device being attached to the plurality of barbs with a biodegradable connection.

9. The attachment system of claim 8, wherein the biodegradable connection is a biodegradable weld.

10. The attachment system of claim 8, wherein the biodegradable connection comprises at least one of a magnesium alloy, silver, a polymer, and a degradable suture.

11. The intravascular device attachment system of claim 1, wherein the intravascular device comprises a through channel configured to allow fluid to flow therethrough in a substantially unimpeded manner.

12. An intravascular device attachment system for attaching an intravascular device to a vessel wall, the system comprising:

an intravascular device; and

biological attachment material connected to the intravascular device, the biological attachment material being configured to attach the intravascular device to the vessel wall, the biological attachment material comprising small intestinal submucosa (SIS); and

a plurality of barbs connected to the intravascular device and configured to anchor the intravascular device to the vessel wall.
