Mechanical anastomosis system for hollow structures
First Claim

1. An applicator for use in a system including joining elements for making an anastomosis between hollow structures, said applicator comprising:
- a head provided with a plurality of arms connected thereto, each said arm having a proximal end and a distal end, and wherein each said arm is movable from a first position at which the distal ends of the arms are separated by a first distance, to a second position, at which the distal ends of said arms are separated by a second distance, the second distance being greater than the first distance; and
a shank-like element comprising a part located proximal to a distal end of said shank-like element for causing movement of the arms from the first position toward the second position, said shank-like element being associated with said head such that movement of one of said shank-like element and said bead relative to the other of said shank-like element and said head, causes said arms to move from said first position toward said second position, andwherein the distal ends of the arms are adapted to support at least a portion of said hollow structures and hold said joining elements while positioning at least one said hollow structure relative to said joining elements for making an anastomosis between the hollow structures, and said positioning of said hollow structures is accomplished by moving said arms from said first position to said second position.

Abstract
A system for making anastomoses between hollow structures by mechanical means is provided with a device in the shape of an annular or tubular element comprising circumferentially provided means, such as pin-shaped elements, for joining the abutting walls of the hollow structures together. An applicator is intended for moving said annular or tubular element in position and activating the joining means thereof, so as to make the anastomosis. Possibly, intraluminal joining means can be inserted without using an annular or tubular element.

30. An applicator for use in a system including joining elements for making an anastomosis between hollow structures, said applicator comprising:
-
a head provided with a plurality of arms connected thereto, each said arm having a proximal end and a distal end, and wherein each said arm is movable from a first position at which the distal ends of the arms are separated by a first distance, to a second position, at which the distal ends of said arms are separated by a second distance, the second distance being greater than the first distance; and a shank-like element associated with said head such that movement of one of said shank-like element and said head relative to the other of said shank-like element and said head, causes said arms to move from said first position toward said second position; a detainer for controlling movement of said joining elements and including a plurality of surface portions positioned to limit the extent of movement of said arms; and wherein the distal ends of the arms are adapted to support at least a portion of said hollow structures and hold said joining elements while positioning at least one said hollow structure relative to said joining elements for making an anastomosis between the hollow structures, and said positioning of said hollow structures is accomplished by moving said arms from said first position to said second position.
