Apparatus and method for performing compressional anastomoses
First Claim
1. A compression device for the anastomosis of a tubular hollow organ, comprising a collapsible member movable between an expanded configuration and a collapsed configuration, said collapsible member having a first end and a second end wherein said collapsible member includes at least one resilient hinge disposed thereon which is parallel to a longitudinal axis of said device to facilitate the collapsibility thereof, said at least one resilient hinge having a greater degree of flexibility than sections of said collapsible member adjoined by said at least one resilient hinge such that said collapsible member remains intact upon collapse thereof.

Abstract
A compression device for the anastomosis of a tubular hollow organ, having a first collapsible member movable between an expanded configuration and a collapsed configuration, said first collapsible member having a first end and a second end; a second collapsible member movable between an expanded configuration and a collapsed configuration, said second collapsible member adapted to be joined with said first end of said first collapsible member; and a third collapsible member adapted to be joined with said second end of said second collapsible member; wherein at least one of said first, second or third collapsible members comprises at least one resilient hinge portion disposed thereon which is parallel to the longitudinal axis of said device to facilitate the collapsibility thereof. Also provided are surgical instruments for carrying and placing the compression device components and a device for approximating surgical devices. A method for forming a compression anastomosis, is also provided.

20. A method for forming a compression anastomosis, comprising the steps of:
-
(a) providing a compression device for the anastomosis of hollow organs, the device including at least three collapsible components, wherein at least one of said at least three collapsible components has at least one resilient hinge portion disposed thereon to facilitate the collapsibility thereof, each of said collapsible components having sidewalls defining an opening; (b) providing a surgical instrument adapted for carrying and attaching at least two of said collapsible components to each other and to the end of a tubular tissue section; (c) providing a surgical device for approximating at least two of said collapsible components, which device includes an elongated housing and at least two approximating members operatively attached to said elongated housing, at least one of said at least two approximating members being operable between a first position and a second position; (d) inserting said collapsible members in open ends of tubular tissue sections to be joined using said surgical instrument for carrying and attaching separate components of a compression anastomosis device to the end of a tubular tissue section; and (e) approximating said inserted first and second tubular tissue members using said approximating device such that said first, second and third collapsible members are interlocked together. - View Dependent Claims (21, 22)

23. A compression device for the anastomosis of a tubular hollow organ, comprising:
-
(a) a first collapsible member movable between an expanded configuration and a collapsed configuration, said first collapsible member having a first end and a second end; (b) a second collapsible member movable between an expanded configuration and a collapsed configuration, said second collapsible member adapted to be joined with said second end of said first collapsible member; and (c) a third collapsible member adapted to be joined with said second end of said second collapsible member; wherein at least one of said first, second or third collapsible members comprises at least one resilient hinge portion disposed thereon which is parallel to the longitudinal axis of said device to facilitate the collapsibility thereof and wherein said first, second and third collapsible members are configured and dimensioned such that they are insertable in a trocar cannula when said first, second, and third collapsible members are in said collapsed configurations.
