Abstract

In one embodiment of the present invention there is provided a biodegradable implantable device. The biodegradable implant device can include one or more elongate spiral support structures that can be biodegradable. Some embodiments can further include a material capture structure that can be biodegradable. A pharmacological agent can also be incorporated into the elongate spiral support structures and/or the material capture structure.

Claims

1. An implantable device, the device comprising:

an elongate support structure element having a first end and a second end, the elongate support structure element arranged in a figure eight configuration to form two loops, wherein the two loops are not coplanar; and

a biodegradable material capture structure extending across at least one loop in a generally planar configuration.

2. The implantable device of claim 1, wherein the elongate support structure element is biodegradable.

3. The implantable device of claim 1, wherein the elongate support structure element is made of a shape memory polymer.

4. The implantable device of claim 1, wherein the two loops are separated by a movable crossover point.

5. The implantable device of claim 4, wherein the material capture structure is attached proximate the movable crossover point.

6. The implantable device of claim 1, wherein at least one of the elongate support structure element and the material capture structure includes a pharmacological agent.

7. The implantable device of claim 6, wherein the pharmacological agent is selected from the group consisting of an anticoagulant, a thrombolytic agent and an antiproliferative agent.

8. An implantable device, the device comprising:

a biodegradable elongate support structure element having a first end and a second end, the elongate support structure element arranged in a figure eight configuration to form two loops, wherein the two loops are not coplanar; and

a material capture structure extending across at least one loop in a generally planar configuration.

9. The implantable device of claim 8, wherein the biodegradable elongate support structure element is made of a shape memory polymer.

10. The implantable device of claim 8, wherein the two loops are separated by a movable crossover point.

11. The implantable device of claim 8, wherein the biodegradable elongate support structure element includes a pharmacological agent.

12. The implantable device of claim 11, wherein the pharmacological agent is selected from the group consisting of an anticoagulant, a thrombolytic agent and an antiproliferative agent.
