Abstract

A soft tissue repair system and method are provided. The soft tissue repair system includes a barbed suture anchoring member attached to at least one suture member. A suture retaining member engages the suture member such that the length and tension of the suture may be selectively adjusted before the suture is permanently engaged in the retaining member. In use, the barbed suture anchoring member and suture member are inserted into the soft tissue repair site and across a tear. The suture member extends back through the original entry side of the tear. A retaining member is applied to the suture member followed by tensioning of the suture member to draw the sides of the tear into apposition. Following tensioning, the retaining member is permanently affixed to the suture member to maintain the selected tension and length of the suture member.

Claims6

Dependent claims

A system for repairing soft tissue comprising:

a barbed suture anchoring member configured and dimensioned to be retained within soft tissue, wherein said barbed suture anchoring member has proximal and distal ends and comprises a pointed distal tip portion having a base, and a series of following sections extending proximally from the base of said distal tip portion, each following section having a larger base than the preceding section;
at least one suture member attached to said barbed suture anchoring member, said suture member integrally comprising two elongated members connected by a plurality of cross rails which are spaced apart so as to define a series of apertures, said suture member having a distal end attached to said barbed suture anchoring member and a proximal end portion;
suture retaining structure for engaging said at least one suture member, said suture retaining structure comprising an insertion member attached to said proximal end portion of said at least one suture member, said insertion member being insertable through at least one of said apertures of said suture member, said insertion member being configured and dimensioned to resist withdrawal.

Dependencies are inferred from the claim text.
