Abstract
A suture passing device includes a jaw assembly that is moved to an open configuration after exiting a hollow needle distal tip and moved to a closed configuration when retracted into the needle tip. The jaw assembly may include a pair of jaw members biased to a default diverging configuration. A suture capturing mechanism formed on the jaw members securely captures suture to both push and pull the captured when the jaw assembly is retracted into the hollow distal tip. The jaw members have configurations of teeth that may be staggered axially and vertically.
Claims19
A suture passing device, comprising:
- a handle;
- a shaft coupled to the handle, the shaft comprising a sharp distal tip that defines a shaft axis, the shaft defining a lumen;
- a jaw assembly housed within the shaft, the jaw assembly comprising a first jaw member and a second jaw member, the first jaw member and the second jaw member being movable with respect to each other between a closed position and an open position, the jaw assembly comprising a suture capturing mechanism;
- an actuating mechanism coupled to the jaw assembly and configured to move the jaw assembly between the closed position and the open position;
- wherein the first jaw member and the second jaw member are biased away from each towards the open position and moved to the open position when the actuating mechanism moves the jaw assembly distally with respect to the shaft such that first jaw member and the second jaw member each diverge from the shaft axis when exiting the shaft, and
- wherein the first jaw member and the second jaw member are moved to the closed position when the actuating mechanism is moved to retract the jaw assembly proximally with respect to the shaft,
- wherein the suture capturing mechanism comprises a first configuration of teeth included in the first jaw member and a second configuration of teeth included in the second jaw member, the second configuration of teeth being axially staggered with respect to the first configuration of teeth.

A suture passing device, comprising:
- a handle;
- a shaft coupled to the handle, the shaft comprising a sharp distal tip that defines a shaft axis, the shaft defining a lumen;
- a ribbon housed within the shaft and including a jaw assembly at a distal section, the jaw assembly comprising a first jaw member and a second jaw member, the first jaw member and the second jaw member being movable with respect to each other between a closed position and an open position, the jaw assembly comprising a suture capturing mechanism, the ribbon comprising a cutout proximal to the suture capturing mechanism;
