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:
an applicator assembly including:
a housing with a cradle fixed to the housing;
a worm drive positioned within the housing with threads extending over a portion of the worm drive;
a cartridge coupled to a distal end of the worm drive, the cartridge configured to hold anchors of the repair device, the cartridge configured to be linearly moved relative to a bed surface of the cradle;
a thumb wheel disposed around the worm drive, the thumb wheel configured to be manually rotated to linearly move the cartridge; and
a flexible finger element coupled to and extending from the worm drive and configured to cooperate with a slot defined in an internal radial surface of the thumb wheel;
wherein, upon manually rotating the thumb wheel, the worm drive rotates upon the flexible finger element being maintained within the slot defined in the internal radial surface of the thumb wheel.
2. The delivery device system of claim 1 , wherein the flexible finger element is sized to linearly translate along the slot.
3. The delivery device system of claim 2 , wherein, upon the cartridge being linearly moved against soft tissue positioned in the cradle, the flexible finger element is configured to slip-out of the slot to an adjacently extending slot to prevent further linear movement of the cartridge toward the bed surface of the cradle.
4. The delivery device system of claim 1 , wherein the flexible finger element comprises a circular member.
5. The delivery device system of claim 1 , wherein the flexible finger element comprises a ring structure.
6. The delivery device system of claim 1 , wherein the flexible finger element is fixed to the worm drive.
7. The delivery device system of claim 1 , wherein the flexible finger element is positioned off-center relative to an axis of the worm drive.
8. The delivery device system of claim 1 , wherein the flexible finger element is configured to flex and move out of the slot so that the flexible finger element moves along the internal radial surface of the thumb wheel to limit a force applied to the soft tissue upon the cartridge being linearly moved against the soft tissue.
9. The delivery device system of claim 8 , wherein the force applied to the soft tissue by a distal end of the cartridge is a function of bendability of the flexible finger element.
10. The delivery device system of claim 1 , wherein, upon the cartridge being linearly moved against the soft tissue, the flexible finger element is configured to flex and move out of the slot to prevent further linear movement of the cartridge against the soft tissue.
