Abstract

A medical device, such as a prosthesis, may include a graft material and a pocket disposed along at least one of luminal and abluminal surfaces of the graft material. The pocket may include a pocket opening leading into an enclosed cavity. The enclosed cavity may be sized to receive at least a portion of a microsystem, and the pocket may be accessible in vivo for removal of the microsystem from the pocket.

Claims

1. An implantable medical device comprising:

a tubular graft material having an abluminal surface and a luminal surface,

a pocket disposed along at least one of the luminal and abluminal surfaces of the graft material, the pocket including a pocket opening leading into an enclosed cavity, the enclosed cavity of the pocket sized to receive at least a portion of a microsystem, wherein the pocket is accessible in vivo for removal of the microsystem from the pocket.

2. The device of claim 1, wherein the pocket is disposed along the luminal surface of the graft material.

3. The device of claim 2, wherein the pocket includes a lid having a base extended from or coupled to the graft material and a lid tip disposed downstream of the base, the lid pivotable about the base between an open configuration and a closed configuration, wherein the lid tip is removably attached to the graft material with a coupling device.

4. The device of claim 3, wherein the lid includes a reinforcement band.

5. The device of claim 3, wherein the coupling device includes a lid magnet and a rim magnet, the lid magnet is coupled to the lid, and the pocket magnet coupled to a pocket edge of the pocket, the rim magnet configured to magnetically couple to the lid magnet when the lid is in the closed configuration.

6. The device of claim 5, wherein the lid magnet extends beyond an edge of the lid tip and includes a grasping feature accessible outside the lid.

7. The device of claim 1, wherein a reinforcement edge band is disposed about a pocket edge that defines the pocket.

8. The device of claim 1, wherein the pocket includes a magnet to couple to the microsystem when disposed within the pocket.

9. The device of claim 8, wherein the microsystem is removably attached within the pocket.

10. The device of claim 1, further comprising a second pocket disposed along the graft material.

11. The device of claim 1, wherein the pocket is defined by a cover graft layer having a proximal end securely attached to the graft material and a distal end removably attached to the graft material.

12. An implantable medical device comprising a tubular graft material having an abluminal surface and a luminal surface, a pocket disposed along the luminal surface of the graft material, the pocket including an opening leading into an enclosed cavity, wherein a portion of the graft material includes a magnet to removably couple to a microsystem when received within the enclosed cavity of the pocket, wherein the pocket is accessible in vivo for removal of the microsystem from the pocket.

13. The device of claim 12, wherein the graft material includes an outer graft layer and an inner graft layer, wherein the opening of the pocket is formed in the inner graft layer, and an inner surface of the outer graft layer includes the magnet.

14. The device of claim 13, wherein the pocket includes a first flap and a second flap, each of the first and second flaps having edges to define a pocket overlapped edge.

15. The device of claim 13, wherein the pocket includes a lid movable between an open configuration and a closed configuration.

16. The device of claim 15, wherein the lid includes a tip magnet, and a pocket edge of the pocket includes a rim magnet configured to magnetically couple to the tip magnet when the lid is in the closed configuration.

17. The device of claim 15, wherein the lid includes a reinforcement band having a grasping feature.

18. An implantable medical device for a microsystem, the device comprising a tubular graft material having an outer layer and an inner layer, a pocket including a pocket opening formed in the inner layer leading into a pocket cavity defined at least partially by the outer layer and the inner layer, the pocket cavity sized to receive at least a portion of a microsystem, the pocket including a reinforced pivotable lid.

19. The device of claim 18, wherein the reinforced pivotable lid includes a tip magnet, and a pocket edge of the pocket opening includes a rim magnet magnetically attracted to the tip magnet, the rim magnet being recessed into the inner layer, wherein when the reinforced pivotable lid is in a closed configuration the lid magnet and the rim magnet are magnetically coupled to one another.

20. The device of claim 19, wherein the outer layer includes an inner surface having a magnet configured to removably couple to the microsystem.
