Abstract
Abstract A system for closing an opening in tissue may include an end effector that holds a staple, where the staple is plastically deformed to a splayed configuration for engaging tissue, then plastically deformed to a closed condition for closing the opening. The system may include one or more butterfly members configured to register the opening to the end effector.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
154 words
A system for closing an opening in tissue, comprising: an end effector having a longitudinal axis, said end effector including at least one paddle; a staple having a plurality of tines, wherein said staple is held by said end effector and wherein at least part of at least one said paddle is movable relative to said staple, and wherein said staple is plastically-deformable from a first configuration to a splayed configuration and then to a closed configuration; a driver positioned proximal to said staple, said driver slidable along at least part of at least one said paddle, wherein said driver is configured for engagement with said staple and at least one said paddle; and wherein said driver is movable to exert a force in the distal direction on a proximal surface of said staple to splay said staple from said first configuration to said splayed configuration and close said staple to said closed configuration.
Claim 2
Independent Claim
154 words
A system for closing an opening in tissue, comprising: an end effector having a longitudinal axis, said end effector including at least one paddle; a staple having a plurality of tines, wherein said staple is held by said end effector and wherein at least part of at least one said paddle is movable relative to said staple, and wherein said staple is plastically-deformable from a first configuration to a splayed configuration and then to a closed configuration; a driver positioned proximal to said staple, said driver slidable along at least part of at least one said paddle, wherein said driver is configured for engagement with said staple and at least one said paddle; and wherein said driver is movable to exert a force in the distal direction on a proximal surface of said staple to splay said staple from said first configuration to said splayed configuration and close said staple to said closed configuration.
Claim 3
Dependent Claim
16 words
The system of claim 1 , wherein said paddle is deflectable away from said longitudinal axis.
Claim 4
Dependent Claim
17 words
The system of claim 1 , wherein at least one said tine has a substantially conical tip.
Claim 5
Dependent Claim
13 words
The system of claim 1 , wherein said staple has two said tines.
Claim 6
Dependent Claim
25 words
The system of claim 1 , further comprising a base from which each said paddle is cantilevered, wherein said paddle extends distally from said base.
Claim 7
Dependent Claim
26 words
The system of claim 2 , wherein said engagement between said driver and at least one said paddle deflects said paddle away from said longitudinal axis.
Claim 8
Dependent Claim
39 words
The system of claim 1 , further comprising a finger extending substantially longitudinally and substantially adjacent to at least one said paddle, wherein said finger includes a projection, and wherein said staple is movable into contact with said projection.
Claim 9
Dependent Claim
14 words
The system of claim 7 , wherein said finger includes a groove defined therein.
Claim 10
Dependent Claim
32 words
The system of claim 8 , wherein said staple includes at least one tab extending therefrom least partially away from at least one said tine, and wherein said tab engages said groove.
Claim 11
Dependent Claim
37 words
The system of claim 7 , wherein said paddle is deflectable away from said finger from an original position, and wherein said paddle is movable back toward its original position to push said staple along said projection.
Claim 12
Dependent Claim
41 words
The system of claim 1 , wherein said end effector includes a housing and at least one butterfly member extending distally from said housing, wherein at least one said butterfly member is movable between a collapsed configuration and an expanded configuration.
Claim 13
Dependent Claim
19 words
The system of claim 11 , wherein at least one said butterfly member is movable relative to said housing.
Claim 14
Dependent Claim
15 words
The system of claim 1 , further comprising a shaft connected to said end effector.
Claim 15
Dependent Claim
14 words
The system of claim 13 , further comprising a handle connected to said shaft.
Claim 16
Dependent Claim
25 words
The system of claim 1 , wherein said staple is initially positioned at a location spaced apart from the distal end of said end effector.
Claim 17
Dependent Claim
14 words
The tool of claim 1 , wherein said staple is a substantially continuous solid.
Claim 18
Dependent Claim
56 words
The tool of claim 1 , wherein at least one said paddle includes a ridge extending therefrom, wherein each said ridge is spaced from the longitudinal centerline of the staple a sufficient distance such that contact between said driver and said staple generates a moment about said ridge that deforms said staple to said splayed configuration.
Claim 19
Dependent Claim
15 words
The tool of claim 1 , wherein the distal end of said driver is bifurcated.
