Abstract
Abstract A cartridge (10) and method used for joining living tissue such as fascia. A staple (14) in the cartridge (10) having pointed arcuate end portions (18) flanking a central portion (16) is bent to provide a generally oval shape for the central portion (16) and adjacent parts of the closed staple, and to bring the terminal parts (19) of the staple into side-by-side crossed relationship with the points (20) on each of the end portions (18) positioned adjacent the central portion (16) of the staple so that each of the end portions (18) of the staple (14) can extend through the tissue on one side of the closed opening and project into the tissue on the other side of the closed opening.

Total Claims: 11
Claim 1
Independent Claim
261 words
A cartridge adapted to be incorporated in a staple forming device for closing an opening in living tissue, said cartridge including at least one open staple comprising a length of wire having a central portion, and end portions at opposite ends of the central portion having points at their distal ends; a frame comprising an anvil adapted to engage said central portion; and a ram movably mounted on said frame and having spaced projections and an end surface therebetween adapted to engage said end portions and bend said staple closed around said anvil, characterized by the feature that the points (20) on said end portions (18) and said central portion (16) are generally aligned, parts of said end portions (18) adjacent said central portion (16) are arcuate, the end surface (36) of said ram (32) and said anvil (28) are shaped to bend the staple (14) around the juncture between said end portions (18) and said central portion (16) to form a generally oval shape for the central portion (16) and adjacent parts of said end portions (18), and to bring the terminal parts (19) of said end portions (18) into side-by-side crossed relationship with the points (20) on each of the end portions (18) positioned adjacent the juncture between the central portion (16) and the other of the end portions (18) so that each of said end portions (18) of the staple (14) when closed can extend through the tissue on one side of the closed opening and project into the tissue on the other side of the closed opening.
Claim 2
Dependent Claim
261 words
A cartridge adapted to be incorporated in a staple forming device for closing an opening in living tissue, said cartridge including at least one open staple comprising a length of wire having a central portion, and end portions at opposite ends of the central portion having points at their distal ends; a frame comprising an anvil adapted to engage said central portion; and a ram movably mounted on said frame and having spaced projections and an end surface therebetween adapted to engage said end portions and bend said staple closed around said anvil, characterized by the feature that the points (20) on said end portions (18) and said central portion (16) are generally aligned, parts of said end portions (18) adjacent said central portion (16) are arcuate, the end surface (36) of said ram (32) and said anvil (28) are shaped to bend the staple (14) around the juncture between said end portions (18) and said central portion (16) to form a generally oval shape for the central portion (16) and adjacent parts of said end portions (18), and to bring the terminal parts (19) of said end portions (18) into side-by-side crossed relationship with the points (20) on each of the end portions (18) positioned adjacent the juncture between the central portion (16) and the other of the end portions (18) so that each of said end portions (18) of the staple (14) when closed can extend through the tissue on one side of the closed opening and project into the tissue on the other side of the closed opening.
Claim 3
Dependent Claim
28 words
A cartridge according to claim 1 further characterized in that the closing of said staple (14) gathers the tissue in the range of about 60 to 70 percent.
Claim 4
Independent Claim
182 words
A method for joining living tissue such as fascia characterized by the steps of: providing a staple (14) comprising a length of wire including a central portion (16) joining end portions (18) having arcuate parts adjacent said central portion (16), which end portions (18) have points (20) at their distal ends with the points (20) on said end portions (18) and said central portion (16) being generally aligned; engaging the points (20) with tissue to be joined; and bending the staple (14) around its junctures between its end portions (18) and its central portion (16) so that the end portions (18) pierce through the engaged tissue, the central portion (16) and adjacent parts of the end portions (18) form a generally oval shape bridging between the pierced portions of the tissue, and each of the end portions (18) crosses the other end portion (18), enters the portion of the tissue pierced by the other end portion (18), and moves to a position with its point (20) adjacent the juncture between the central portion (16) and the other of the end portions (18).
Claim 5
Independent Claim
182 words
A method for joining living tissue such as fascia characterized by the steps of: providing a staple (14) comprising a length of wire including a central portion (16) joining end portions (18) having arcuate parts adjacent said central portion (16), which end portions (18) have points (20) at their distal ends with the points (20) on said end portions (18) and said central portion (16) being generally aligned; engaging the points (20) with tissue to be joined; and bending the staple (14) around its junctures between its end portions (18) and its central portion (16) so that the end portions (18) pierce through the engaged tissue, the central portion (16) and adjacent parts of the end portions (18) form a generally oval shape bridging between the pierced portions of the tissue, and each of the end portions (18) crosses the other end portion (18), enters the portion of the tissue pierced by the other end portion (18), and moves to a position with its point (20) adjacent the juncture between the central portion (16) and the other of the end portions (18).
