Surgical implant and method and instrument for installing the same
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.
1. A surgical method of sealing tissue comprising:
providing a fastener supporting member supporting a plurality of fasteners and having a plurality of compressible members, the fastener supporting member having a first surface facing towards a first direction, the compressible members extending from the fastener supporting member in a direction generally opposite the first direction;
providing a receiver member having a second surface facing the first surface of the fastener supporting member;
clamping tissue between the first surface on the fastener supporting member and the second surface on the receiver member; and
advancing the plurality of fasteners into the receiver member, the plurality of fasteners compressing the compressible members in accordance with a distance of advancement of the fasteners, the distance relating to a thickness of tissue between the first and second surfaces;
wherein the receiver member includes a retainer positioned therein, and the step of advancing the plurality of fasteners advances the plurality of fasteners into engagement with the retainer; and
wherein the fastener supporting member includes a further retainer positioned therein, and the step of advancing the plurality of fasteners advances the plurality of fasteners through the retainer in the fastener supporting member.
2. The method according to claim 1 , wherein the step of advancing the plurality of fasteners deforms the plurality of compressible members.
3. The method according to claim 1 , wherein the plurality of compressible members flex to absorb excess forces to accommodate an increase in pressure in sealed tissue.
4. The method according to claim 1 , wherein the retainer in the receiver member has a plurality of openings, and barbs of the plurality of fasteners engage the retainer in the receiver member adjacent to the openings.
