## 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

### Claim 1

A surgical implant configured to accommodate a range of tissue thicknesses, the implant comprising a retainer, first and second fasteners and first and second compressible members, the first and second fasteners engaging the retainer, the first fastener engageable with the first compressible member and the second fastener engageable with the second compressible member, wherein the first compressible member is compressible in accordance with a distance of advancement of the first fastener and the second compressible member is compressible in accordance with a distance of advancement of the second fastener, the distances of advancement of the first and second fasteners dependent on a tissue thickness through which the fasteners advance;
wherein the retainer includes a plurality of openings and a plurality of strands, wherein the first fastener includes a first plurality of barbs and the second fastener includes a second plurality of barbs, wherein each barb of the first and second plurality of barbs is receivable in one of the plurality of openings, the first and second plurality of barbs moving apart the plurality of strands during deployment of the first and second fasteners into the plurality of openings, at least a portion of the plurality of openings formed by the plurality of strands;
wherein the first and second fastener and the first and second plurality of barbs are rigid.

### Claim 2 (depends on 1)

The surgical implant according to claim 1, wherein the first and second compressible members apply a force to the respective first and second fasteners in a direction opposite a direction in which the first and second fasteners advance through tissue.

### Claim 3 (depends on 2)

The surgical implant according to claim 2, wherein the first and second compressible members comprise tower-like structures having a base engageable by a base of one of the fasteners.

### Claim 4 (depends on 3)

The surgical implant according to claim 3, wherein the base of the fastener presses against the base of the tower-like structure to deform the tower-like structure.

### Claim 5 (depends on 2)

The surgical implant according to claim 2, wherein the first fastener straddles the first compressible member and the second fastener straddles the second compressible member.

### Claim 6 (depends on 1)

The surgical implant according to claim 1, further comprising a receiver member having first and second shields, the shields shielding penetrating tips of the first and second fasteners.

### Claim 7 (depends on 1)

The surgical implant according to claim 1, further comprising a receiver member, wherein the first and second fasteners are supported on a fastener supporting member and the extent of compression of the first and second compressible members is dependent on the thickness of tissue positioned between a first tissue contacting surface of the fastener supporting member and a second tissue contacting surface of the receiver member.

### Claim 8 (depends on 1)

The surgical implant of claim 1, wherein the first and second fasteners are deployable from a fastener supporting member toward a receiver member to penetrate tissue and to engage the retainer supported by the receiver member to couple the fastener supporting member and the receiver member together.

### Claim 9 (depends on 1)

The surgical implant according to claim 1, wherein the distance of advancement of the first fastener is the same as the distance of advancement of the second fastener.

### Claim 10 (depends on 1)

The surgical implant according to claim 1, wherein the distance of advancement of the first fastener is different than the distance of advancement of the second fastener.

### Claim 11 (depends on 1)

The surgical implant according to claim 1, wherein the first plurality of barbs are offset from each other and the second plurality of barbs are offset from each other.

### Claim 12 (depends on 1)

The surgical implant according to claim 1, wherein the first plurality of barbs are aligned with each other and the second plurality of barbs are aligned with each other.
