Abstract
Abstract In apparatus for applying a plurality of surgical fasteners to body tissue clamped between fastener holding and anvil parts of the apparatus, tissue edge control members extend into at least one end, and preferably both ends, of the fastener array to prevent any portion of the tissue from extending beyond the ends of the array. This ensures that the fastener array extends completely across the tissue and that no portion of the tissue remains unfastened.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
101 words
An apparatus for applying a plurality of surgical fasteners to body tissue comprising: a fastener holder cartridge containing an array of fastener in parallel rows; an anvil opposite said cartridge for clamping of body tissue therebetween; a pusher for expelling said array of fasteners from said cartridge towards said anvil part for applying the fasteners to the body tissue; and a tissue edge control member at least at one side of said anvil in longitudinal alignment with at least one row of fasteners and extending within said array of fasteners to confine the clamped body tissue within said array of fasteners.
