Suture locks, as well as related systems and methods, are provided for fixing strands of one or more sutures relative to tissue. The suture locks, systems and methods are simple and reliable in use, facilitate complete perforation closure and adjustment of the suture strands, and are adaptable to a variety of suture fixation and perforation closure situations. The suture lock includes a locking pin and a retaining sleeve. The locking pin has a main body and a grip. The retaining sleeve has a tubular body with an internal wall defining an internal passageway sized to receive the locking pin therein. The suture lock is operable between a locked configuration and unlocked configuration. In the locked configuration, the suture strands are compressed between the grip and the internal wall of the tubular body.

1. A suture lock for fixing strands of one or more sutures relative to tissue, the suture lock comprising: a suture strand;a locking pin having a main body and a grip formed at a distal tip of the main body, the main body defining a longitudinal axis, the grip extending radially from the main body and defining an annular edge, the grip including a leading surface located distally of the annular edge and a trailing surface located proximally of the annular edge, the leading surface being tapered from the annular edge towards the longitudinal axis;a retaining sleeve having a tubular body with an internal wall defining an internal passageway sized to receive the locking pin and its grip therein, the internal passageway having a uniform diameter along the longitudinal length of the tubular body; andthe suture lock being operable between a locked configuration and an unlocked configuration, the locking pin and the retaining sleeve being connected in the locked configuration and being separated in the unlocked configuration, the locking pin and the retaining sleeve sized and structured to compress the suture strand between the grip and the internal wall of the tubular body, and between the main body and the internal wall of the tubular body, in the locked configuration, the main body defining a reduced diameter portion proximal to the grip, the reduced diameter portion sized relative to the internal wall to not compress the suture strand between the reduced diameter portion and the internal wall. 2. The suture lock of claim 1, wherein the suture strands are compressed between the annular edge of the grip and the internal wall of the tubular body in the locked configuration. 3. The suture lock of claim 1, wherein, in the locked configuration, the leading and trailing surfaces of the grip are structured to permit translation of the suture strands in a proximal direction and prevent translation of the suture strands in a distal direction. 4. The suture lock of claim 1, wherein the leading surface of the grip is dome-shaped. 5. The suture lock of claim 1, wherein the leading surface is curved. 6. The suture lock of claim 1, wherein the trailing surface is transverse to the longitudinal axis. 7. The suture lock of claim 1, wherein the reduced diameter portion is immediately proximal to the grip. 8. The suture lock of claim 1, wherein the main body defines a tapered portion proximal to the grip, the tapered portion having diameters smaller than an adjacent portion of the main body to reduce the friction between the suture strands, the locking pin and the sleeve proximate the tapered portion. 9. The suture lock of claim 1, further comprising a stop extending radially from the main body and positioned to abut the retaining sleeve. 10. The suture lock of claim 9, wherein the stop extends entirely around the periphery of the main body of the locking pin. 11. The suture lock of claim 1, wherein the stop includes a distally facing surface and a proximally facing surface, the distally facing surface being tapered towards the main body. 12. The suture lock of claim 1, wherein the reduced diameter portion has a uniform diameter along its length. 13. A suture lock for fixing strands of one or more sutures relative to tissue, the suture lock comprising: a locking pin having a main body and a grip, the main body defining a longitudinal axis, the grip extending radially from the main body and defining an annular edge, the grip including a leading surface located distally of the annular edge and a trailing surface located proximally of the annular edge, the leading surface being tapered from the annular edge towards the longitudinal axis;a retaining sleeve having a tubular body with an internal wall defining an internal passageway sized to receive the locking pin and its grip therein; andthe suture lock being operable between a locked configuration and an unlocked configuration, the locking pin and the retaining sleeve being connected in the locked configuration and being separated in the unlocked configuration, the locking pin and the retaining sleeve sized and structured to compress a suture strand between the grip and the internal wall of the tubular body in the locked configuration;wherein the locking pin has stop extending radially from the main body at a location distal to a proximal end of the locking pin to define a second shoulder facing proximally, the stop having a distally facing surface sized and positioned to abut a proximal end surface of the tubular body of the retaining sleeve, the distally facing surface tapered towards the longitudinal axis and wherein the retaining sleeve includes a peripheral rim extending radially from the tubular body to define a first shoulder facing proximally, and further comprising a first pushing catheter defining a first lumen sized to receive the tubular body of the retaining sleeve and abut the first shoulder, and a second pushing catheter defining a second lumen sized to receive the main body of the locking pin and abut the second shoulder. 14. The suture lock of claim 13, wherein the first lumen of the first pushing catheter is sized to receive the second pushing catheter. 15. The suture lock of claim 13, wherein the stop of the locking pin is sized to abut against the tubular body of the retaining sleeve to limit the position of the locking pin relative to the retaining sleeve. 16. The suture lock of claim 13, wherein the stop extends entirely around the periphery of the main body of the locking pin. 17. The suture lock of claim 13, wherein, in the locked configuration, the leading and trailing surfaces of the grip, and the distally facing surface of the stop, are structured to permit translation of the suture strands in a proximal direction and prevent translation of the suture strands in a distal direction. 18. The suture lock of claim 13, wherein the second lumen of the second pushing catheter is sized to provide a friction fit with the proximal end of the locking pin. 19. The suture lock of claim 13, wherein, the second lumen of the second pushing catheter is sized to provide a friction fit with the proximal end of the locking pin, and that the first lumen of the first pushing catheter is sized to provide a friction fit with the retaining sleeve.
