Abstract
A flexible clip applier includes a flat wire wound tubular coil, a pair of jaws at the end of the coil, end effector wires extending through the coil and coupled to the jaws, and a clip-advancing wire extending through the coil. A clip chamber is defined in the distal end of the coil. The clip-advancing wire includes a clip pusher which advances a clip into the jaws when the clip-advancing wire is moved distally. The jaws include channels in which a distalmost clip rides when the jaws are closed and the pusher is advanced, thereby causing the distalmost clip to be pushed over the tissue, and a distal anvil which operate to bend a portion of the clip to facilitate its retention on the clamped tissue. Rotation of the clip-advancing wire effects rotation of the jaws are rotatable about a longitudinal axis of the device.
