Abstract

A surgical implant comprising a receiver member and deployment member for clamping and sealing tissue of variable thickness, a corresponding applicator tool and surgical system for connecting, sealing, fastening and/or attaching tissue to itself, to other tissue and/or to non-tissue structures, and/or sealing the flow of fluid at and/or between structures such as tissue and vessel structures.

Claims

1. A surgical implant comprising:

a fastener supporting member having a first surface facing towards a first direction;

at least one fastener supported by the fastener supporting member;

at least one compressible member extending from the fastener supporting member in a direction generally opposite the first direction; and

a receiver member having a second surface facing the first surface of the fastener supporting member;

wherein deployment of the at least one fastener toward the receiver member compresses the at least one compressible member.

2. The surgical implant according to claim 1, wherein the fastener supporting member is comprised of an elastomeric material.

3. The surgical implant according to claim 1, wherein the at least one compressible member has a base and the at least one fastener has a base engageable with the base of the compressible member, the base of the at least one fastener applying a force to the base of the at least one compressible member to deform the at least one compressible member.

4. The surgical implant according to claim 1, wherein the at least one fastener includes a plurality of individual fasteners arranged along a row substantially parallel to a longitudinal axis of the fastener supporting member.

5. The surgical implant according to claim 4, wherein the receiver member includes a plurality of shields arranged along a row substantially parallel to a longitudinal axis of the receiver, each of the plurality of shields being positioned opposite a fastener.

6. A surgical implant according to claim 1, further comprising a retainer positioned within the receiver member.

7. The surgical implant of claim 6, wherein the retainer includes a plurality of openings forming a plurality of openings, wherein the at least one fastener is receivable within one or more of the openings.

8. The surgical implant of claim 7, wherein the at least one fastener is receivable within one of the openings.

9. The surgical implant according to claim 1, wherein the extent of compression of the at least one compressible member is dependent on a thickness of the tissue clamped between the fastener supporting member and the receiver member.

10. The surgical implant according to claim 1, wherein the compressible member includes a tower extending substantially perpendicular to a base of the fastener supporting member.

11. The surgical implant according to claim 10, wherein the tower has a base engageable by

the at least one fastener to deform the tower.

12. The surgical implant according to claim 11, wherein the deformed tower applies a counterforce to the at least one fastener in a direction opposite a direction in which the at least one fastener is deployed.

13. The surgical implant according to claim 12, wherein the at least one fastener extends through the fastener supporting member.

14. The surgical implant according to claim 1, wherein the fastener supporting member and the receiver member are connected to each other at an end.

15. The surgical implant according to claim 14, wherein the end comprises a hinge.

16. A surgical implant comprising:

a fastener carrying member having a ventral surface and a dorsal surface opposite the ventral surface; and

a receiver member;

the fastener carrying member supporting a plurality of fasteners and a plurality of dorsally extending compressible members, each of the fasteners engageable with one of the dorsally extending compressible members, the plurality of fasteners deployable through the fastener carrying member, wherein deployment of at least a portion of the plurality of fasteners in a first direction towards the receiver member compresses the dorsally extending compressible members corresponding to the portion of the plurality of fasteners.

17. The surgical implant according to claim 16, further comprising a retainer positioned within the fastener carrying member, wherein the plurality of fasteners when deployed extend through the retainer.

18. The surgical implant according to claim 16, wherein the plurality of dorsally extending compressible members apply a force in a second direction opposite the first direction in which the plurality of fasteners are deployed.

19. A surgical implant comprising a fastener carrying member and a receiver member, the fastener carrying member supporting a plurality of fasteners and a plurality of compressible members, each of the compressible members having a first height, and each of the fasteners arranged with one of the compressible members;

wherein the fastener carrying member has a first surface and a second opposing surface, wherein the first surface faces the receiver member, the fasteners deployable in a direction toward the first surface, and the plurality of compressible members extend from the second surface of the fastener carrying member in a direction away from the first surface;

wherein the receiver member is arranged with respect to the fastener carrying member such that during deployment of at least one of the plurality of fasteners, at least one of the fasteners extends at least partially into the receiver member to retain the compressible member at a height smaller than the first height.

20. The surgical implant according to claim 19, wherein the plurality of compressible members apply a force to the plurality of fasteners in a direction away from the direction of initial deployment of the plurality of fasteners.

21. The surgical implant according to claim 20, wherein the plurality of compressible members comprise towers extending in a direction away from the receiver member.

22. The surgical implant according to claim 20, wherein the plurality of compressible members includes a quantity including three to thirty.

23. The surgical implant according to claim 19, further comprising a receiver member having a retainer, the retainer having a plurality of openings formed therein to receive the plurality of fasteners.

24. A surgical implant comprising:

a fastener supporting member and a receiver member configured to be brought into apposition with each other, the fastener supporting member having a ventral surface facing the receiver member, the fastener supporting member having a plurality of fasteners arranged along a longitudinally extending row substantially parallel to a longitudinal axis of the implant;

a retainer positioned in the fastener supporting member and having a plurality of openings, the plurality of fasteners retained by engagement with the plurality of openings in the retainer, and

a plurality of compressible members engageable by the plurality of fasteners, the plurality of compressible members compressed by the plurality of fasteners and extending from the fastener supporting member in a direction generally opposite the direction the ventral surface faces.

25. A surgical implant configured to be implanted about a tissue-based surgical structure, the surgical implant comprising:

a fastener supporting member having a base and a ventral side;

a receiver member;

at least one fastener supported by the fastener supporting member;

at least one compressible member extending dorsally from the base of the fastener supporting member; and

wherein the receiver member comprises a base and a ventral side, the ventral side of the receiver member arranged to face the ventral side of the fastener supporting member during deployment of the at least one fastener;

wherein deployment of the at least one fastener towards the receiver member compresses the at least one compressible member.
