Surgical fastener apparatus
First Claim
1. Apparatus for applying a plurality of surgical fasteners to body tissue or the like by gripping body tissue between fastener holding means and fastener closure means, applying the fasteners to the body tissue, and closing the fasteners, which comprises means for pivotally biasing at least one of said fastener holding means and said fastener closure means toward a position which provides separation of the body tissue from said fastener holding means and fastener closure means, and means for resisting the force of said pivotal biasing means, said resisting means being disengaged after the fasteners have been closed.

2. Apparatus for applying a plurality of surgical fasteners to body tissue or the like, which comprises:
-
body means; fastener closure means at one end portion of said body means for providing closure of surgical fasteners; fastener holding means mounted relative to said fastener closure means, said fastener holding means being adapted for holding a plurality of surgical fasteners; at least one of said fastener holding means and fastener closure means being biased toward a first spaced position for reception of body tissue or the like therebetween, whereby the body tissue is contacted by said fastener holding means and said fastener closure means; means for moving at least one of said fastener holding means and fastener closure means toward the other to a second position sufficient to clamp the body tissue positioned therebetween; means for moving the surgical fasteners toward said fastener closure means to effect closure of the surgical fasteners; means for pivotally biasing at least one of said fastener holding means and fastener closure means toward a position which provides separation of the tissue from said fastener holding means and said fastener closure means, and means for resisting the force of said biasing means, said resisting means being disengaged after said surgical fasteners have been moved to effect closure.

3. Apparatus for applying a plurality of surgical fasteners to body tissue or the like, which comprises:
-
body means; fastener closure means at one end portion of said body means for providing closure of surgical fasteners; fastener holding means mounted relative to said fastener closure means, said fastener holding means being adapted for holding a plurality of surgical fasteners; at least one of said fastener holding means and fastener closure means being biased toward a first spaced position for reception of body tissue or the like therebetween, whereby the body tissue is contacted by said fastener holding means and said fastener closure means; means for moving at least one of said fastener holding means and fastener closure means toward the other to a second position sufficient to clamp the body tissue positioned therebetween; means for moving the surgical fasteners toward said fastener closure means to effect closure of the surgical fasteners; and means for biasing at least one of said fastener holding means and fastener closure means toward a position whereby the space therebetween exceeds the spaced associated with said first position, whereby the force of said biasing means is resisted by resisting means which is disengaged after said surgical fasteners have been moved to effect closure. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

15. Apparatus for substantially simultaneously applying a plurality of surgical fasteners to body tissue or the like, which comprises
a body having a longitudinal portion enclosing axial drive means, a distal portion thereof defining a tissue reception aperture; -
fastener closure means positioned at the distal portion of said tissue reception aperture; fastener holding means pivotally mounted relative to said fastener closure means adjacent one end portion thereof and defining a space therebetween, said fastener holding means containing a plurality of surgical fasteners arranged in generally parallel rows extending generally transversely to said longitudinal portion and fastener pushing means for substantially simultaneously pushing said surgical fasteners; releasable means for longitudinally advancing said fastener holding means distally to a closed position at least sufficient to contact body tissue positioned within said aperture, and for returning said fastener holding means to a proximal position; means for reception of user applied force and for translating same to distally directed drive force on said axial drive means generally in alignment with said longitudinal portion; means for translating said distally directed drive force to said fastener pushing means; first means for applying a biasing force to said fastener holding means to pivot said fastener holding means into an opened position; second means for initially resisting the biasing force of said first means until said second means moves to a released condition; and
,third means for releasing said second means in response to both application of said drive force along said axial drive means and release of said releasable means for longitudinally advancing said fastener holding means. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
