Apparatus and methods for attaching soft tissue to bone
First Claim
1. A suture anchor for attaching soft tissue to bone comprising:
- a free-floating base having a top surface, a bottom surface, a hole extending from the top surface to the bottom surface, and at least two eyelet holes extending completely through the base from the top surface to the bottom surface;
a catheter positioned through the hole of the base, the catheter having an elongated shaft with a proximal end, a distal end, a longitudinal axis therebetween, and at least one inner lumen for a light curable adhesive to pass therethrough;
a balloon portion engaging the catheter, wherein the balloon portion expands from a deflated state to an inflated state when the light curable adhesive is delivered to the balloon portion, wherein the catheter extends proximally and distally from the balloon portion; and
a plurality of suture material passing through the eyelet holes to attach the soft tissue to the bone,wherein the free-floating 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.

Abstract
Suture anchors and methods for using the suture anchors for attaching soft tissue, such as ligaments, tendons, and muscles, to bone are disclosed. 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 between the proximal and distal ends, wherein the catheter has at least one inner lumen capable of allowing a light curable adhesive to pass through the inner lumen; 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.

10. A suture anchor for attaching soft tissue to bone comprising:
-
a base having a top surface, a bottom surface, a hole extending from the top surface to the bottom surface, and at least two eyelets holes extending completely through the base from the top surface to the bottom surface; a catheter positioned through the hole of the base, the catheter including a lumen for passing a light cure adhesive into an expandable member portion of the catheter to inflate the expandable member portion, wherein the catheter extends proximally and distally from the expandable member portion; at least one light guide extending from the catheter into the expandable member portion to guide light into the expandable member portion; and a plurality of suture material passing through the eyelets holes to attach the soft tissue to the bone, wherein the base directly engages the expandable member portion so as to be rotated by the expandable member portion as the expandable member portion inflates. - View Dependent Claims (11, 12)

13. A suture anchor for attaching soft tissue to bone comprising:
-
a rotatable oblong base having a top surface, a bottom surface, a central hole extending from the top surface to the bottom surface, and two pairs of eyelets holes extending from the top surface to the bottom surface; a catheter positioned through the central hole of the rotatable oblong base, the catheter including a lumen for passing a light cure adhesive into an expandable member portion of the catheter to inflate the expandable member portion, wherein the catheter extends proximally and distally from the expandable member portion; and a plurality of suture material passing between each of the pairs of eyelets holes to attach the soft tissue to the bone, wherein the rotatable oblong base directly engages the expandable member portion so as to be rotated by the expandable member portion as the expandable member portion inflate. - View Dependent Claims (14, 15)
