Adjustable loop knotless anchor
View Patent ↗An adjustable loop knotless anchor assembly having an adjustable loop suture element that utilizes an adjustable or sliding knot for length adjustment during a tissue repair. The slidable knot is located on a sleeve that is placed into a bone mass for capturing an anchor element. The anchor element captures the adjustable loop and then is inserted into the sleeve. The anchor element is adjusted for securing it in a locked position within the sleeve for secure attachment of the anchor element therein.
1. An adjustable loop knotless anchor assembly comprising:
an anchor element with a snag means located on an end;
a hollow cylindrical or cup-shaped sleeve having a first end and a second end; and
at least one adjustable suture loop element directly attached to the first end of the sleeve, the at least one adjustable suture loop element having a one-way slidable knot along its length for adjusting the length of the at least one suture loop element, wherein the snag means captures said at least one loop suture loop element during or prior to insertion of the anchor element into the sleeve and locks the anchor element into the sleeve and the length of the at least one suture loop element is then adjusted via the one-way slidable knot to draw a tissue into secure attachment with a bone mass wherein the one-way slidable knot is located at a point where the at least one suture loop element is attached to the first end of the sleeve.
2. The adjustable loop knotless assembly of claim 1 , further comprising a locking means within the sleeve to facilitate capture of the anchor element in the sleeve.
3. The adjustable loop knotless assembly of claim 1 , wherein the snag means is a recess in the leading edge of the anchor element.
4. The adjustable loop knotless assembly of claim 1 , further comprising threads on an exterior of said sleeve to facilitate secure attachment of said sleeve to the bone mass.
5. The adjustable loop knotless assembly of claim 1 , wherein the anchor element with the snag means is secured with the adjustable suture loop element within the sleeve.
6. The adjustable loop knotless assembly of claim 1 , wherein the anchor element with the snag means is locked with the adjustable suture loop element on a bottom of the sleeve.
7. The adjustable loop knotless assembly of claim 1 , wherein the one-way slidable knot is positioned at a point of direct attachment of the adjustable suture loop element of the sleeve.
