Abstract
Medical devices for cinch and cutting one or more suture, and methods for making and using such devices are disclosed. An example medical device may include a coupler, a sleeve releasably coupled to the coupler, a cutter slidably disposed within the sleeve, and a suture cinching member movable into and out of the sleeve. A wire may extend through and be longitudinally movable within the coupler to move the suture cinching member and cutter.
Claims20
A medical device for cinching and cutting one or more sutures, the medical device comprising:
- a coupler having a coupler lumen;
- a sleeve releasably coupled to the coupler, the sleeve having a sidewall defining a sleeve lumen, the sidewall having a window into the sleeve lumen;
- a cutter slidably disposed within the sleeve, the cutter having a cutting surface;
- a suture cinching member moveable into and out of the sleeve lumen;
- and
- a wire extending through and longitudinally movable within at least the coupler, the wire releasably connected to the cutter.
A medical device for applying a cinch to one or more sutures, the medical device comprising:
- an elongate shaft defining a shaft lumen;
- a sleeve having a sleeve lumen and a window extending into the sleeve lumen;
- first and second opposing clamp arms fixed to a yoke, wherein the yoke is axially moveable within the sleeve lumen between a first position in which distal ends of the first and second opposing clamp arms are spaced apart, and a second position in which the distal ends are in contact with one another;
- a cutter coupled to the first and second opposing clamp arms, the cutter defining a cutting surface, the cutter configured such that when the first and second opposing clamp arms are moved from the first position to the second position over one or more sutures, the first and second opposing clamp arms clamp the one or more sutures and the cutting surface cuts the one or more sutures.
A method of cinching and cutting one or more sutures, the method comprising:
- engaging one or more sutures with a suture cinching member, a distal portion of the suture cinching member disposed distal of a sleeve and a proximal portion of the suture cinching member disposed within a lumen of the sleeve, the suture cinching member connected to a cutter slidably disposed within the sleeve lumen;
- and
- moving the suture cinching member and connected cutter proximally into the sleeve, thereby engaging a cutting surface on the cutter with the one or more sutures and cutting the one or more sutures.
