Independent Claim
162 words
A surgical instrument (10) for applying a surgical fastener (30) to torn tissue, said
fastener including a first leg (194) and a second leg (194) joined by a flexible
material (198), said instrument comprising: a handle mechanism (32, 34) including at least one movable member (32); an elongate body portion (24) with a distal end; means (190) for releasably engaging said fastener such that the fastener is
held at the distal end of the body portion, characterized by the first and second legs being held aligned with
the long axis of the body portion; and means (38, 40) positioned in said body portion for advancing said first leg
of said fastener into said tissue, and subsequently advancing said second leg of said
fastener into said tissue, along a line of advance which corresponds to the length
direction of the respective fastener leg and the long axis of the body portion, said
means for advancing being responsive to movement of said handle mechanism.
