Devices, systems, and methods for repairing soft tissue and attaching soft tissue to bone
Devices, systems and/or methods for repairing soft tissue adjacent a repair site. In one embodiment, a repair device is delivered with a delivery device system configured to move a cartridge with the repair device disposed therein toward an anvil with soft tissue positioned thereon. The delivery device linearly moves the cartridge toward the anvil with a worm drive positioned within a housing by rotating a thumb wheel disposed around the worm drive. Such linear movement is provided with a finger element extending from the worm drive that is configured to cooperate with an internal surface of the thumb wheel. With this arrangement, upon rotating the thumb wheel, the worm drive rotates with the finger element engaged with the internal surface of the thumb wheel to linearly move the cartridge toward the anvil.
1. A delivery device system for fixating a repair device to soft tissue at a soft tissue repair site, comprising:
a deployment mechanism having a handle associated with a trigger, the handle and trigger sized and configured to manually deploy the repair device into soft tissue with a push rod moveable along an axis, the push rod linearly moveable by the deployment mechanism and extending distally from the deployment mechanism;
a housing extending longitudinally along the push rod;
an anvil and cartridge configured to be coupled to the housing, the cartridge at least partially holding the repair device;
a worm drive positioned within the housing;
a thumb wheel disposed around the worm drive, the thumb wheel configured to be rotated to linearly move the worm drive with threads defined in at least one of the worm drive and the thumb wheel such that the worm drive is configured to linearly move the cartridge relative to a bed surface of the anvil; and
a finger element extending from the worm drive and configured to cooperate with an internal surface of the thumb wheel such that, upon rotating the thumb wheel, the worm drive rotates with the finger element engaged with the internal surface of the thumb wheel.
2. The delivery device system of claim 1 , wherein the internal surface of the thumb wheel defines multiple slots therein, the finger element sized to linearly translate along one slot of the slots as the worm drive rotates.
3. The delivery device system of claim 2 , wherein, upon the cartridge being linearly moved against soft tissue positioned in the anvil, the finger element is configured to slip-out of the one slot to prevent further linear movement of the cartridge toward the bed surface of the anvil.
4. The delivery device system of claim 1 , wherein the finger element comprises a circular member.
5. The delivery device system of claim 1 , wherein the finger element comprises a ring structure.
6. The delivery device system of claim 1 , further comprising a stroke regulator positioned between the deployment mechanism and the worm drive.
7. The delivery device system of claim 6 , wherein the stroke regulator comprises an elastomer material.
