Abstract
A device configured as a knot pusher and/or a suture trimmer is provided. The device can deliver and secure a suture knot. The apparatus can also trim the suture after the suture knot is secured.
Claims26
A device for delivering, securing and trimming a suture, the device comprising:
- a shaft assembly extending between a distal end and a proximal end, the shaft assembly including:
- a sheath having a proximal end, a distal end and a lumen having an inner diameter, the sheath also having a suture access port formed in a portion of a side wall of the sheath adjacent the distal end of the sheath, the suture access port having a proximal end and a distal end;
- a shaft slidably disposed inside the sheath, the shaft having a proximal end, a distal end, and an outer diameter that is selected to permit the shaft to fit within the lumen of the sheath in a close tolerance relationship while allowing the shaft to move axially relative to the sheath, and the shaft being movable relative to the sheath between a first position, wherein the distal end of the shaft is positioned between the distal end and proximal end of the suture access port, and a second position, wherein the distal end of the shaft is positioned beyond of the distal end of the suture access port;
- wherein the distal end of the shaft assembly is configured to push a knot formed in the suture;
- and
- wherein the distal end of the shaft and the distal end of the suture access port are configured to trim the suture as the shaft is moved from the first position to the second position.

A device for delivering and securing a suture, the device comprising:
- a distal end having a tip configured to push a knot in the suture;
- a proximal end;
- a shaft assembly extending between the distal end and the proximal end, the shaft assembly including:
- a sheath, the sheath having a suture access port;
- and
- a shaft slidably disposed inside the sheath, wherein a distal end of the shaft cooperates with the suture access port to trim the suture after the knot is tightened.
3 more elements
A device for delivering and securing a suture, the device comprising:
- a distal end having a tip configured to push a knot in the suture;
- a proximal end having a housing, wherein a bias mechanism is located within the housing;
- a shaft assembly extending between the distal end and the proximal end, the shaft assembly including:
- a sheath, the sheath having a suture access port, wherein the tip and the suture cooperate to form a suture path through the device;
- and
- a shaft slidably disposed inside the sheath, wherein only the shaft is slidably disposed inside the sheath
- wherein a distal end of the shaft is advanced distally to cooperate with the suture access port to trim the suture after the knot is tightened,
- the bias mechanism prevents the shaft from being prematurely advanced distally, and
- the shaft passes through the housing such that a proximal end of the shaft is configured such that a user can advance the shaft distally.
