Method and apparatus for performing end-to-end anastomoses
First Claim
1. A device for use in performing an end-to-end anastomosis, comprising:
- a stapling member insertable into a first end segment of a tubular organ;
a plurality of staples arranged in a circular array in said stapling member;
an anvil member insertable into a second end segment of said tubular organ, said stapling member being movably connected to and at least partially insertable into said anvil member to enable a clamping of said first and said second end segment to one another in juxtaposition to said circular array and between said stapling member and said anvil member; and
staple ejection means in said stapling member for ejecting said staples in a substantially radial outward direction towards said anvil member and through said first and said second end segment, thereby stapling said first and said second end segment to one another along an annular locus.

Abstract
A device for use in performing an end-to-end anastomosis comprises a stapling member insertable into a first end segment of a tubular organ, a plurality of staples arranged in a circular array in the stapling member, and an anvil member insertable into a second end segment of the tubular organ. The anvil member is movably connected to the stapling member to enable a clamping of the first and the second end segment to one another in juxtapositon to the circular array. A staple ejector is provided in the stapling member for ejecting the staples in a radial direction towards the anvil member, thereby stapling the first and the second end segment to one another along an annular locus.

3. A method for use in performing an end-to-end anastomosis, comprising the steps of:
-
inserting a stapling member into a first end segment of a tubular organ, said stapling member having a plurality of staples arranged in a circular array; inserting an anvil member into a second end segment of said tubular organ; moving said anvil member and said stapling member towards one another so as to insert said stapling member at least partially into said anvil member and thereby clamp said first and said second end segment between said stapling member and said anvil member in juxtaposition to said circular array; and ejecting said staples in a substantially radial outward direction from said stapling member towards said anvil member and through said first end segment and said second end segment, thereby stapling said first and said second end segment to one another along an annular locus. - View Dependent Claims (4)

5. A stapling member for cooperating performing with an anvil member to perform an end-to-end anastomosis, comprising:
-
a body insertable into a first end segment of a tubular organ; a plurality of staple arranged in a circular array in said body, said staple having legs oriented in at least one substantially radial plane in said body; means on said body for movably connecting said body to the anvil member so that said body is inserted into said anvil member to enable a clamping of first and second end organ segments to one another in juxtaposition to said circular array of staples and between said body and said anvil member; and staple ejection means in said body for ejecting said staples in said plane towards said anvil member, thereby stapling said first and said second end segment to one another along an annular locus.
