Apparatus and method for preforming anastomosis fastener securement of hollow organs
First Claim
1. Apparatus for performing anastomosis on hollow organs comprising:
- an annular hollow sleeve shaped fastener securing anvil formed in size and shape to annularly encompass the outer periphery of a first hollow organ adjacent a severed end thereof to be anastomosed to a severed end or side of a second hollow organ, said anvil having a plurality of prepositioned and annularly disposed fastener securing means on the exterior thereof;
an anastomotic surgical fastener driving instrument unattached to said anvil and having opposing clamp jaws, the interior annular combined contours of said jaws when clamped together form an annulus, and conform to outer annular contours of said anvil for annularly confining therebetween for anastomosis a cuff portion formed from a first hollow organ end everted over said anvil in intimal coaptation with an end or side portion of a second hollow organ positioned over the cuff formed on the first organ end;
guide means on said anvil and jaw for keying said jaws, when clamped, in predetermined alignment with said anvil;
fastener cartridge means retained in at least one of said jaws with fasteners prepositioned along the inside thereof for cooperation with said fastener securing means on said anvil for securing said fasteners when driven inwardly toward said anvil; and
fastener driving means on said instrument for driving said fasteners inwardly through intimal coaptating hollow organ portions for securing by said fastener securing means on said anvil.

Abstract
An anastomosis fastening technique wherein an annular fastener securing anvil is positioned over the end portion of a first hollow body organ to be joined to a second hollow body organ end or side portion and this first organ end is everted outwardly back over the anvil thereby forming a cuff. The anvil is provided with prepositioned and annularly disposed fastener securing devices on the exterior surface. The second hollow body organ and/or side portion is then positioned over the cuff of the first hollow body organ such that the intimal portions thereof to be anastomosed are in intimal coaptation. An anastomotic surgical fastener driving instrument with fastener cartridges therein, and which conforms in shape to the outer annular contours of the anvil is coaxially applied over the anvil with the organ portions positioned therebetween and the fastener driving instrument is then actuated to fasten the coaptating organ portions together. The organ portions to be anastomosed may first be tied down to the anvil. The fastener driving instrument is also keyed to the anvil for proper positioning of the fasteners relative to the anvil fastener securing devices prior to actuating the fastener driving instrument. The fasteners may be in the form of surgical staples, nails or tacks.

15. A method for joining hollow body organs by anastomosis fastener securement comprising the steps of:
- applying an annular fastener securing anvil over an open end portion of a first hollow body organ to be joined to a second open hollow body organ end or side portion and everting said first open end portion outwardly back over said anvil thereby forming a cuff portion, said anvil having a plurality of prepositioned and annularly disposed fastener securing means on the exterior thereof under the cuff portion;
positioning said second open hollow body organ end or side portion over said cuff portion of said first hollow body organ such that the intimal portions of said organs to be anastomosed are in intimal coaptation;
positioning an anastomotic surgical fastener driving instrument, which has at least one fastener cartridge therein containing a plurality of fasteners and conforms in shape to outer annular contours of said anvil, annularly over said anvil and said organ portions with said organ portions positioned on said anvil in intimal cooptation; and
actuating said fastener driving instrument and thereby fastening and coaptating organ portions together by driving the fasteners therethrough and securing them with said fastener securing means. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
