1. A device for applying a hemostatic clip assembly, the device comprising:
a proximal delivery catheter including a proximal handle assembly and an elongated catheter body extending distally from the proximal handle assembly, the elongated catheter body defining a longitudinal axis; and
a distal clip assembly removably connected to a distal end of the elongated catheter body, the distal clip assembly including a distal clip housing, a jaw assembly having a pair of cooperating jaw members fixed to the distal clip housing by a first pin, the first pin oriented orthogonally relative to the longitudinal axis, and a jaw adapter yoke operatively connected to the jaw members, wherein the proximal delivery catheter is configured and adapted to transmit linear motion along the longitudinal axis and torsion about the longitudinal axis to at least a portion of the distal clip assembly, wherein at least one of the jaw members is configured and adapted to rotate about the first pin between an open configuration and a closed configuration
wherein the distal clip assembly includes a second pin connecting between the jaw members and the jaw adapter yoke, wherein each jaw member includes a proximal body portion and a distal end effector, wherein the proximal body portion of each jaw member includes a respective cam slot configured and adapted to receive the second pin and a pivot aperture configured and adapted to receive the first pin,
wherein the second pin is configured and adapted to translate within the cam slots to move axially relative to the distal clip housing and the jaw assembly to move the jaw members between the open configuration where respective distal tips of the jaw members are moved away from one another, the closed configuration where the respective distal tips of the jaw members are approximated towards one another to grasp tissue, and a locked configuration, and
wherein each cam slot includes a proximal locking neck projecting into the cam slot defining a proximal locking area, wherein the jaw members are in the locked configuration when the second pin is proximal relative to the proximal locking neck in the proximal locking area.
