Strand for minimally invasive removal of T-anchor
View Patent ↗An anchoring device includes (a) a flexible member extending from a proximal end to a distal end and (b) an elongated anchor member extending from a first end to a second end and attached to the distal end of the flexible member such that the anchor member is movable between an insertion configuration in which the anchor member is substantially parallel to the flexible member and a locked configuration in which the anchor member is substantially perpendicular to the flexible member in combination with (c) a flexible removal element extending from a proximal end to a distal end attached to the first end of the anchor member.
1. An anchoring device, comprising:
a flexible member extending from a proximal end to a distal end;
an elongated anchor member extending from a first end to a second end and attached to the distal end of the flexible member such that the anchor member is movable between an insertion configuration in which the anchor member is substantially parallel to the flexible member and a locked configuration in which the anchor member is substantially perpendicular to the flexible member; and
a flexible removal element extending from a proximal end to a distal end attached to the first end of the anchor member, a length of the removal element being selected so that, when the anchor member is implanted in a desired location, the removal element extends back along an insertion path through which the anchor member was inserted to the desired location so that drawing the removal element proximally out of the path moves the anchor member to the insertion configuration and draws the anchor member through the insertion path.
2. The device of claim 1 , wherein the proximal end of the removal element includes a loop.
3. The device of claim 1 , wherein the removal element is colored such that it is easily visible and differentiated from the flexible member.
4. The device of claim 1 , wherein the flexible member is one of a suture, thread, cable and wire.
5. The device of claim 1 , wherein the removal element is one of a suture, thread, cable and wire.
6. The device of claim 1 , wherein the distal end of the flexible member is attached to a portion of the anchor member approximately midway between the first end and the second end.
7. The device of claim 1 , wherein the flexible member includes a channel extending therethrough along a portion thereof from an inlet along a sidewall thereof to an outlet along a sidewall thereof, the removal element passed through the channel from the inlet to the outlet such that the proximal end of the removal element extends proximally out of the outlet.
