1. A method of connecting a first hollow structure to a second hollow structure, comprising:
- creating an opening in the second hollow structure;
providing a device having a body and a plurality of arms pivotably attached to the body, each of the plurality of arms having a proximal end and a distal end, the plurality of arms being movable about the proximal end from a first position, where the distal ends of the arms are separated by a first distance which is less than a distance of separation between the proximal ends of the anus in the first position, and a second position, where the distal ends of the arms are separated by a second distance, the second distance being greater than the first distance;
positioning at least a portion of each of the plurality of arms within the opening of the second hollow structure while the plurality of arms are in the first position;
moving the plurality of arms from the first position to the second position; and
creating an anastomosis between the first hollow structure and the second hollow structure.

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.

12. A method of connecting a first hollow structure to a second hollow structure, comprising:
-
creating an opening in the second hollow structure; providing a device having a body and a plurality of arms movably attached to the body, each of the plurality of arms having a proximal end and a distal end, the plurality of arms being movable about the proximal end from a first position, where the distal ends of the arms are separated by a first distance, and a second position, where the distal ends of the arms are separated by a second distance, the second distance being greater than the first distance, and wherein the the plurality of arms converge about a central longitudinal axis of the device from the proximal ends towards the distal ends when in the first position; positioning at least a portion of each of the plurality of arms within the opening of the second hollow structure while the plurality of arms are in the first position; moving the plurality of arms from the first position to the second position; and creating an anastomosis between the first hollow structure and the second hollow structure. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method of connecting a first hollow structure to a second hollow structure, comprising:
-
creating an opening in the second hollow structure; providing a device having a body, a plurality of arms movably attached to the body, and a sleeve, each of the plurality of arms having a proximal end and a distal end, the plurality of arms being movable about the proximal end from a first position, where the distal ends of the arms are separated by a first distance, and a second position, where the distal ends of the arms are separated by a second distance, the second distance being greater than the first distance, and at least a portion of each of the plurality of arms is disposed within the sleeve; positioning at least a portion of each of the plurality of arms within the opening of the second hollow structure while the plurality of arms are in the first position; moving the plurality of arms from the first position to the second position in a manner whereby movement of the plurality of arms is limited by the sleeve; and creating an anastomosis between the first hollow structure and the second hollow structure. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31)
