Claims
- 1. A device for positioning a knot in suture strands tightly against tissue within a patient, said device comprising a main body having a central, elongated axis, a distal end and a proximal end, said distal end having an end opening generally in alignment with the elongated axis of the device, and a side opening in the side wall of the device with a passageway between said end opening and said side opening.
- 2. A device as defined in claim 1 wherein said side opening is located in close proximity to said distal end.
- 3. A device as defined in claim 2 wherein said side opening is located within about 2 cm. to about 4 cm. from said distal end.
- 4. A device as defined in claim 1 wherein said end opening has a predetermined diameter, said diameter being just slightly larger than the diameter of a single strand of suture.
- 5. A device as defined in claim 1 wherein said end opening has a diameter that is about one to ten thousandths of an inch larger than the diameter of a single strand of a suture.
- 6. A device as defined in claim 1 wherein the passageway has a coaxial portion extending coaxially along the longitudinal axis of the main body to a transition area located between the coaxial portion of the passageway and the side opening.
- 7. A device as defined in claim 6 wherein the transition area has an arcuate surface.
- 8. A device as defined in claim 7 wherein said transition area widens in the direction of the side opening.
- 9. A device as defined in claim 8 wherein said side opening is located about 2 to 4 centimeters from said distal end.
- 10. A device for positioning a knot in suture strands tightly against tissue within a patient, said device comprising a main body having a central, elongated axis, a distal end and a proximal end, said distal end having a rounded end surface and having an end opening generally in alignment with the elongated axis of the device, a side opening in the side wall of the device and a passageway between said end opening and said side opening, said passageway having a coaxial portion extending inwardly from said end opening for a predetermined distance terminating at an inward end and having a transition portion extending from the inward end of said coaxial portion to said side opening, said transition portion comprised of an arcuate solid surface within said device.
- 11. A device as defined in claim 10 wherein said transition portion of said passageway creates a bend of about ninety degrees in said passageway.
- 12. A device as defined in claim 11 wherein said transition portion widens in the direction toward said side opening.
- 13. A device as defined in claim 12 wherein said main body is comprised of a metal material.
- 14. A device as defined in claim 10 wherein said end opening is about one to ten thousandths of an inch larger than the diameter of a single suture strand.
- 15. A device as defined in claim 14 wherein said side opening is located about 2 to 4 centimeters from said distal end.
- 16. A method of tying a suture knot to join tissue together of a patient, said method comprising the steps of:
providing a device having a distal end, a proximal end and an exterior side surface, and wherein the device has an end opening at the distal end and a side opening in the exterior side surface with a passageway between the end opening and the side opening, passing a suture strand through the tissue of a patient to provide two loose ends of the suture strand, inserting one of the loose ends into the end opening and threading that loose end through the passageway to be accessible at the side opening of the device, tying a knot between the loose ends, pushing the device toward the tissue being sutured to move the knot into a location tightly pressed again the tissue, and pulling on one or both of the loose ends of the suture strands to tighten the knot while holding the knot located in said position tightly pressed against that tissue.
- 17. A method as defined in claim 16 wherein said step of pulling on one of the loose ends of the suture strand comprises pulling on the loose end of the suture strand that has passed through the passageway.
- 18. A method as defined in claim 16 wherein said step of providing a device comprises providing a device having an end opening just slightly larger than a single suture strand.
- 19. A method as defined in claim 16 wherein said step of providing a device comprises providing a device wherein the passageway has a coaxial portion extending inwardly of the end opening for a predetermined distance coaxial with the longitudinal axis of the device and an arcuate transition portion that extends from said coaxial portion to the side opening.
- 20. A method as defined in claim 16 wherein said step of providing a device comprises providing a device wherein the transition portion widens in the direction of the side opening.
