Tissue anchor deployment device, systems, and methods

A method of securing an implant to tissue in an operative space in a body of a patient, comprising:

• advancing the implant into the operative space within an elongate shaft of an implant delivery device;
• deploying the implant adjacent tissue within the operative space;
• inserting a tissue anchor delivery device into the operative space, the tissue anchor delivery device comprising:
• a handle;
• an elongate shaft extending distally from the handle, the elongate shaft having a length from the handle to a distal end of the elongate shaft of at least 10 cm;
• a tissue anchor magazine coupled to the handle in communication with the elongate shaft, the tissue anchor magazine having a plurality of tissue anchors disposed therein;
• and
• a tissue anchor advancement mechanism configured to advance the plurality of tissue anchors from the tissue anchor magazine out the distal end of the elongate shaft;
• actuating the tissue anchor advancement mechanism to deploy at least one tissue anchor of the plurality of tissue anchors out the distal end of the elongate shaft into the implant and tissue within the operative space;
• wherein the tissue anchor advancement mechanism is configured to advance only one tissue anchor of the plurality of tissue anchors along the length of the elongate shaft at a time.

A system for delivering tissue anchors into an operative space in a body of a patient, comprising:

• a tissue anchor delivery device comprising a handle and an elongate shaft extending distally from the handle;
• and
• a tissue anchor magazine separate and detached from the tissue anchor delivery device, the tissue anchor magazine having a plurality of tissue anchors stored therein;
• wherein the tissue anchor magazine is configured to be delivered subcutaneously into the operative space separate from the tissue anchor delivery device.
