Tissue fixation delivery apparatus
First Claim
1. A device for deploying tissue anchors, the device comprising:
- a handle defining an internal cavity;
a tubular assembly extending distally from the handle and comprising a groove and a first side opening;
a needle cannula comprising an outer wall, a proximal portion disposed within the tubular assembly, an opposite sharpened distal tip having a distal opening, an internal chamber extending from the proximal portion through the distal opening, and a second side opening through the outer wall;
a plunger assembly slidably coupled to the handle and comprising a proximal end positioned external to and proximal to the handle and a push rod assembly, wherein portions of the plunger assembly are slidably disposed within the handle, the tubular assembly, and the needle cannula; and
a resilient band disposed about the tubular assembly within the groove and over the first side opening;
wherein the device is configured and arranged so that, prior to deployment, a first tissue anchor can be disposed within the internal chamber of the needle cannula and a second tissue anchor can be disposed external to the internal chamber within the first side opening in the tubular assembly, and wherein the plunger assembly is positioned to prevent the second tissue anchor from entering the internal chamber while the resilient band operates to urge the second tissue anchor toward the internal chamber.

Abstract
A device for deploying a tissue fixation apparatus of the type including first and second tissue anchors coupled together by an adjustable suture assembly. The device comprises a handle mechanism and a needle cartridge assembly releasably coupled to the handle mechanism. The needle cartridge assembly includes a needle cannula with a side opening through which a tissue anchor can be loaded into an internal chamber of the needle cannula. A push rod is disposed in the needle cannula and is operable between an extended position in which the push rod prevents the tissue anchor from entering the chamber through the side opening, and a retracted configuration in which the tissue anchor can be pushed into the chamber under the action of a resilient band positioned over the side opening.

14. A device for deploying a tissue fixation apparatus, the device comprising:
-
a handle defining an internal cavity; a tubular shaft extending distally from the handle; a plunger slidably coupled to the handle and comprising a proximal end positioned external to the handle and a distal end positioned within the internal cavity of the handle; a handle push rod extending from the distal end of the plunger and slidably disposed within the tubular shaft; a needle cannula comprising an outer wall, a proximal portion, an opposite sharpened distal tip having a distal opening, an internal chamber extending from the proximal portion through the distal opening, and a needle side opening through the outer wall; a tubular sleeve disposed about a portion of the needle cannula and releasably mateable with the tubular shaft, the tubular sleeve comprising a groove and a sleeve side opening; a cartridge push rod slidably disposed within the internal chamber of the needle cannula and releasably mateable with the handle push rod; and a resilient band disposed about the tubular sleeve within the groove and over the sleeve side opening; wherein the device is configured and arranged to receive a first tissue anchor within the internal chamber of the needle cannula and a second tissue anchor within the side sleeve opening and external to the internal chamber of the needle cannula. - View Dependent Claims (15, 16, 17, 18, 19, 20)
