Claim 7

A suture fastener according to claim 2 wherein the second end of the male component comprises having a pocket.

Claim 8

A suture fastener according to claim 6 wherein said pocket is defined by a slot-shaped recess.

Claim 9

A suture fastener comprising: a male component having a first and a second end, said male component having an approximately cylindrical shape with an outside surface; and a generally ring shaped female component having a top surface and a bottom surface and a bore for receiving the male component, said bore having an inside surface, the top surface further including a shoulder portion behind which the first end of the male component is retained upon insertion of the first end of the male component into and through the bore from the bottom surface, a suture being clamped between the approximately cylindrical outside surface of the male component and the inside surface of the bore in the female component upon insertion of the male component into the female component.

Claim 10

A suture fastener comprising: a male component having a first and a second end, said male component having an approximately cylindrical shape with an outside surface; and a generally ring shaped female component having a top surface and a bottom surface and a bore for receiving the male component, said bore having an inside surface, the top surface further including a shoulder portion behind which the first end of the male component is retained upon insertion of the first end of the male component into and through the bore from the bottom surface, a suture being clamped between the approximately cylindrical outside surface of the male component and the inside surface of the bore in the female component upon insertion of the male component into the female component.

Claim 11

A suture fastener according to claim 8, wherein: the male component defines a taper between the first and second ends of the outside surface of said cylindrical shape; and the inside surface of the bore in the female component defines a corresponding taper.

Claim 12

A suture fastener according to claim 8, wherein the first end of said male component defines a flange, the flange capable of engaging the top surface of the female component upon insertion of the flange into and through the bore from the bottom surface, to interlock said male component and female component.

Claim 13

A suture fastener according to claim 10, wherein there is a groove defined across the flange, said groove for receiving a portion of a suture to be fastened.

Claim 14

A suture fastener according to claim 8, wherein the second end of said male component defines a pocket.

Claim 15

A suture fastener according to claim 8, wherein the male component and the female component are formed from a bio dissolvable material.

Claim 16

A fastener for fastening two ends of a suture comprising: a male component and a female component configured to interlock and clamp two ends of a suture between them; said male component being made of a resilient material configured as a tapered member having a flange at one end, the flange being divided into two halves by a groove, the two halves of the flange being capable of being flexed towards one another in a resilient manner; the female component being generally ring-shaped and having a central opening sized to receive the tapered member and having a shoulder on one side of the opening for engaging the flange of the male component, the flange of the male component being retained behind the shoulder of the female component when the components are interlocked together; the male component and a female component being disposed on opposite sides of the two ends of the suture with the two ends of the suture being disposed in the groove so that the groove retains and locates the suture in a predetermined position across the male component; and the two ends of the suture being held in place by clamping action provided by an interference fit between the inner surface of the female component and the tapered member of the male component.

Claim 17

A fastener for fastening two ends of a suture comprising: a male component and a female component configured to interlock and clamp two ends of a suture between them; said male component being made of a resilient material configured as a tapered member having a flange at one end, the flange being divided into two halves by a groove, the two halves of the flange being capable of being flexed towards one another in a resilient manner; the female component being generally ring-shaped and having a central opening sized to receive the tapered member and having a shoulder on one side of the opening for engaging the flange of the male component, the flange of the male component being retained behind the shoulder of the female component when the components are interlocked together; the male component and a female component being disposed on opposite sides of the two ends of the suture with the two ends of the suture being disposed in the groove so that the groove retains and locates the suture in a predetermined position across the male component; and the two ends of the suture being held in place by clamping action provided by an interference fit between the inner surface of the female component and the tapered member of the male component.

Claim 18

A suture fastener according to claim 14, wherein the male component and the female component are formed from a bio dissolvable material.
