Apparatus and methods for attaching soft tissue to bone
First Claim
1. A method for using a suture anchor to engage a soft tissue to a bone comprising:
- forming an access hole in a bone, the access hole having a diameter and extending through a cortical bone into a cancellous bone;
providing a suture anchor to the access hole, the suture anchor comprising at least one suture material connected to a base and a balloon portion engaged to a catheter and being capable of expanding from a deflated state having a deflated diameter to an inflated state having an inflated diameter when a light curable adhesive is delivered to the balloon portion, wherein the base directly engages the balloon portion and is adapted to rotate relative to the catheter as the balloon portion expands from the deflated state to the inflated state;
placing the suture anchor into the cancellous bone while the balloon portion is in a deflated state and the at least one suture material extends from the cancellous bone through the compact outer layer of the bone;
delivering a light curable adhesive to the balloon portion to expand the balloon portion from the deflated state to the inflated state, wherein the inflated diameter is greater than the diameter of the access hole; and
activating a light source to deliver light to the light curable adhesive in the balloon portion to cure the light curable adhesive.

Abstract
Suture anchors and methods for using the suture anchors for attaching soft tissue, such as ligaments, tendons, and muscles, to bone are disclosed herein. A suture anchor for attaching soft tissue to bone includes a catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, wherein the catheter has at least one inner lumen capable of allowing a light curable adhesive to pass therethrough; a balloon portion engaging the distal end of the catheter, wherein the balloon portion expands from a deflated state to an inflated state when a light curable adhesive is delivered to the balloon portion; and at least one suture material for passing through soft tissue to attach the soft tissue to a bone.

8. A method for attaching a soft tissue to a bone comprising:
-
forming an access hole in a bone, the access hole having a diameter and extending through a cortical bone into a cancellous bone; placing a balloon portion attached to a catheter into the cancellous bone through the access hole while the balloon portion is in a deflated state having a deflated diameter, and wherein the catheter extends proximally and distally from the balloon portion; engaging a base to the balloon portion to position the balloon portion between the base and the access hole, and extending at least one suture material from the base through the compact outer layer of the bone, wherein the base directly engages the balloon portion and is adapted to rotate relative to the catheter as the balloon portion expands from the deflated state to the inflated state; delivering a light curable adhesive to the balloon portion to expand the balloon portion from the deflated state to the inflated state having an inflated diameter, wherein the inflated diameter is greater than the diameter of the access hole; activating a light source to deliver light to the light curable adhesive in the balloon portion to cure the light curable adhesive; and attaching the soft tissue to the bone using the at least one suture material. - View Dependent Claims (9, 10, 11, 12, 13, 14)
