Abstract: A surgical clamp jaw is disclosed, having an inner profile and a deflection control profile opposite the inner profile. In one embodiment, the inner profile has a first substantially concave profile in an unclamped position and a second substantially flat profile in a clamped position. In one embodiment, the deflection control profile has one or more sets of corresponding abutment surfaces, at least one set of which is not contacting each other when the inner profile is in the unclamped position and which is contacting each other when the inner profile is in the clamped position. In one embodiment, the surgical clamp jaw defines one or more flexion assistance voids, wherein at least one of the one or more flexion assistance voids is in contact with a gap between one of the one or more sets of corresponding abutment surfaces.

Abstract: A jaw closure mechanism for use in a surgical clip applier having first and second jaws movable relative to one another between a spaced-apart position and an approximated position to form a surgical clip about tissue. The jaw closure mechanism includes first and second eccentric wheels rotatably coupled to the respective first and second jaws. Each of the wheels includes a center and a pivot point that is offset relative to the center. A cable is disposed about each of the wheels. The cable is engaged to the first wheel at a first engagement point and to the second wheel at a second engagement point such that, upon application of a drive force to the cable, the wheels are rotated and displaced relative to the respective jaws from a first position to a second position to urge the jaws from the spaced-apart position to the approximated position.

Abstract: A system may include an introducer sheath including a retention member configured to anchor the introducer sheath in a natural body lumen having a wall. The system may also have an elongate member extending along a longitudinal axis through a working channel of the introducer sheath. Additionally, the system may have a manipulating portion coupled to a distal end of the elongate member. The manipulating portion may include at least one selectively actuatable member configured to transition between an undeployed configuration and a deployed configuration. In the undeployed configuration, the at least one actuatable member may extend substantially parallel to the longitudinal axis and in at least one position in the deployed configuration, the at least one actuatable member may extend radially outwardly from the longitudinal axis. In the deployed configuration, the manipulating portion and elongate member may be configured to be proximally retracted toward the working channel of the introducer sheath so as to move a distal portion of the wall towards a proximal portion of the wall.

Abstract: A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one exemplary embodiment, a surgical clip applier is provided having a housing with a trigger movably coupled thereto and an elongate shaft extending therefrom with opposed jaws formed on a distal end thereof. The trigger is adapted to advance a clip to position the clip between the jaws, and to move the jaws from an open position to a closed position to crimp the clip positioned therebetween.
