Abstract
A suture device includes a suture ring that defines an arcuate channel extending therein. A first arcuate needle passer is slidingly disposed within a first side of the arcuate channel and a second arcuate needle passer is slidingly disposed within a second side of the arcuate channel. An arcuate needle is passable between the first arcuate needle passer and the second arcuate needle passer and includes a first latching feature adapted to releasably secure the arcuate needle to the first arcuate needle passer and a second latching feature adapted to releasably secure the arcuate needle to the second arcuate needle passer.
Claims20
A suture device comprising:
- a mounting structure adapted to be secured relative to a distal end of an endoscope;
- a suture ring secured relative to the mounting structure, the suture ring defining an arcuate channel extending within the suture ring;
- a first arcuate needle passer slidingly disposed within a first side of the arcuate channel, the first arcuate needle pass including a working end and a control end;
- a second arcuate needle passer slidingly disposed within a second side of the arcuate channel, the second arcuate needle passer including a working end and a control end;
- a first control element operably coupled to the control end of the first arcuate needle passer;
- a second control element operably coupled to the control end of the second arcuate needle passer;
- wherein the first control element and the second control element cross over each other upon entering the arcuate channel of the suture ring;
- and
- an arcuate needle releasably securable to the first arcuate needle passer.
A suture device adapted to be used in combination with an endoscope, the suture device comprising:
- a suture ring having a first side and a second side, and defining an arcuate channel extending within the suture ring;
- a first tubular member comprising a curved distal portion that curves in a direction opposed to a direction of curvature of the first side of the suture ring;
- a second tubular member comprising a curved distal portion that curves in a direction opposed to a direction of curvature of the second side of the suture ring;
- a first arcuate needle passer slidingly disposed within a first side of the arcuate channel,
- a second arcuate needle passer slidingly disposed within a second side of the arcuate channel;
- a first control element disposed within the first tubular member and operably coupled to the first arcuate needle passer;
- a second control element disposed within the second tubular member and operably coupled to the second arcuate needle passer;
- and
- an arcuate needle passable between the first arcuate needle passer and the second arcuate needle passer by manipulating the first control element and the second control element;
- wherein the first control element and the second control element cross over each other upon entering the arcuate channel of the suture ring.
A suture device adapted to be used in combination with an endoscope, the suture device comprising:
- an end cap ring adapted to be secured to a distal end of an endoscope;
- a C-shaped suture ring secured to the end cap ring, the C-shaped suture ring having a first side and a second side, and defining an arcuate channel extending within the suture ring;
- a first arcuate needle passer slidingly disposed within a first side of the arcuate channel,
- a second arcuate needle passer slidingly disposed within a second side of the arcuate channel;
- a first control element that is adapted to enter the first side of the arcuate channel substantially parallel to a tangent of the first needle passer proximate where the first control element is secured to the first needle passer;
- a second control element that is adapted to enter the second side of the arcuate channel substantially parallel to a tangent of the second needle passer proximate where the second control element is secured to the second needle passer;
- and
- an arcuate needle passable between the first arcuate needle passer and the second arcuate needle passer by manipulating the first control element and the second control element;
- wherein the first control element and the second control element cross over each other upon entering the arcuate channel of the C-shaped suture ring.
