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. A clip pusher is provided at a distal end of the clip-advancing wire, and 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. The device can push a clip with a force in excess of 1500 grams.

35. A flexible surgical device, comprising:
-
a) a flexible outer tubular member having proximal and distal ends;
b) a flexible advancing element extending through said tubular member and having proximal and distal ends; and
c) a handle coupled to said flexible outer tubular member and to said flexible clip-advancing element and adapted to move said advancing element distally relative to said tubular member, wherein said flexible advancing element, said tubular member, and said handle are adapted such that said handle under manual application of force can cause said advancing element to provide a distal pushing force of at least 500 grams at said distal end of said advancing element. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
