Abstract

A one-way adjustable suture retaining device suitable for use in arthroscopic surgery to secure one end of a braided suture comprising a frustum having an end and a base wherein a passage extends from the end to the base and the end has a plurality of slits extending from the end towards the base defining at least two flexible fingers and a process for using the retaining device to secure at least one end of a suture.

Claims

1. A sterile one piece, one-way adjustable suture retaining device suitable for use in arthroscopic surgery to secure a braided suture comprising a frustum having an end and a base wherein a passage extends from the end to the base the end has a plurality of slits extending from the end towards the base defining at least two flexible fingers that are configured to engage the braided suture when the braided suture is advanced from the end toward the base.

2. The sterile retaining device of claim 1 wherein the retaining device has four flexible fingers.

3. The sterile retaining device of claim 1 wherein a sterile braided suture is present in the passage.

4. The sterile retaining device of claim 1 wherein the suture retaining device is made of a biocompatible material selected from the group consisting of titanium, tantalum, homopolymers of ε

-caprolactone, homopolymers of glycolide, homopolymers of lactide, homopolymers of p-dioxanone, copolymers of ε

-caprolactone, copolymers of glycolide, copolymers of lactide and copolymers of p-dioxanone.

5. A process for securing one end of a braided suture that has been passed through a tissue relative to the tissue comprising placing a sterile one piece, one-way adjustable suture retaining device composed of a frustum having an end and a base wherein a passage extends from the end to the base and the end has a plurality of slits extending from the first end towards the base defining at least two flexible fingers, on the braided suture with the base oriented toward the tissue and advancing the braided suture retaining device relative to the braided suture by passing the braid suture through the passage for the base to the end until the base contacts the tissue, wherein the flexible fingers are configured to engage the braided suture when the braided suture is advanced from the end toward the base.
