Abstract

A tissue repair device includes a closed knotless loop of multifilament flexible material, and a fixation member having a structure that defines a cavity that receives at least a part of the closed loop. The tissue repair device may include a flexible member traversing the loop. The loop may include a portion in which ends of the multifilament flexible material are thermally fused together. The multifilament flexible material may be braided or twisted.

Claims

1. A tissue repair device comprising:

a closed loop of multifilament flexible material, wherein the loop is knotless and includes a contact portion in which ends of the multifilament flexible material are interwoven and form a blended region having a uniform or homogenous composition when energy sufficient to melt or liquefy the ends is supplied to the ends of the multifilament flexible material;

a substantially rigid first fixation member having a structure that defines first and second through holes, the first through hole receiving a first part of the closed loop of multifilament flexible material and the second through hole receiving a second part of the closed loop of multifilament flexible material; and

a flexible member slidably received through the contact portion of the closed loop and having an end that passes through an opening defined in a second fixation member and passes through a region of the flexible member that has not been passed through the second fixation member to form a second, knotless closed loop to secure the second fixation member to the flexible member.

2. The tissue repair device of claim 1 wherein the contact portion comprises a Chinese trap.

3. A tissue repair device comprising:

a closed loop of multifilament flexible material, wherein the loop is knotless and includes a contact portion in which ends of the multifilament flexible material are interwoven and form a blended region having a uniform or homogenous composition when energy sufficient to melt or liquefy the ends is supplied to the ends of the multifilament flexible material;

first and second substantially rigid fixation members, the first fixation member having a structure defining first and second through holes, the first through hole receiving a first part of the closed loop of multifilament flexible material and the second through hole receiving a second part of the closed loop of multifilament flexible material, and the second fixation member having a structure defining an opening; and

a flexible member slidably received through the contact portion of the closed loop and having an end that passes through the opening in the second fixation member and passes through a region of the flexible member that has not been passed through the second fixation member to form a second, knotless closed loop to secure the second fixation member to the flexible member.

4. The tissue repair device of claim 3 wherein the contact portion comprises a Chinese trap.
