Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
Apparatus for applying an array of surgical fasteners to body tissue comprising: a plurality of surgical fasteners in a predetermined array, said array being subdivided into first and second subarrays; first and second pusher means for respectively pushing the fasteners in the first and second subarrays into the tissue; first means for supplying the work required for pushing the fasteners into the tissue; and second means for optionally transmitting the work supplied by the first means to either the first and second pusher means together or to the first pusher means only.
Claim 2
Dependent Claim
92 words
Apparatus for applying an array of surgical fasteners to body tissue comprising: a plurality of surgical fasteners in a predetermined array, said array being subdivided into first and second subarrays; first and second pusher means for respectively pushing the fasteners in the first and second subarrays into the tissue; first means for supplying the work required for pushing the fasteners into the tissue; and second means for optionally transmitting the work supplied by the first means to either the first and second pusher means together or to the first pusher means only.
Claim 3
Dependent Claim
52 words
The apparatus defined in claim 1 wherein the fastener array is planar, wherein the fasteners are pushed into the tissue along an axis substantially perpendicular to the plane of the array, and wherein the first means comprises a substantially rigid first member substantially parallel to and at least coextensive with the array.
Claim 4
Dependent Claim
39 words
The apparatus defined in claim 2 wherein the second means comprises: a second member interposed between the first member and the first pusher means; and a third member selectively interposable between the first member and the second pusher means.
Claim 5
Dependent Claim
67 words
The apparatus defined in claim 3 wherein the second means further comprises: third means for mounting the third member for motion substantially parallel to the array between a first position in which the third member is interposed between the first member and the second pusher means and a second position in which the third member is not interposed between the first member and the second pusher means.
Claim 6
Dependent Claim
28 words
The apparatus defined in claim 4 wherein the first means further comprises detent means for releasably retaining the third member in either the first or the second position.
