Abstract
Abstract A staple and stapler and introducer are disclosed for closing a wound and for wound site management. The staple is deformable, and includes a plurality of tissue-piercing prongs which are expanded outwardly, inserted into tissue and collapsed inwardly to close the wound. The stapler includes a plurality of mechanisms to deform the staple into various positions. An introducer is provided that includes a plurality of spaced-apart wire guides for securing and centering the wound opening during a medical procedure, and during closure of the wound.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
A tissue stapler, comprising an elongated sleeve having an inside diameter, an elongated rod with a flared mandrel couple to a distal end, the rod and mandrel sized to fit within the inside diameter of the sleeve; an actuator mechanism to move the rod relative to the sleeve, a staple adapted to fit between said mandrel and said sleeve, and said actuator mechanism adapted to move said mandrel relative to said staple and said sleeve causing said staple to close on tissue located about a wound site; wherein said mandrel causing at least a portion of said staple to expand before causing said staple to close on said tissue.
Claim 2
Dependent Claim
109 words
A tissue stapler, comprising an elongated sleeve having an inside diameter, an elongated rod with a flared mandrel couple to a distal end, the rod and mandrel sized to fit within the inside diameter of the sleeve; an actuator mechanism to move the rod relative to the sleeve, a staple adapted to fit between said mandrel and said sleeve, and said actuator mechanism adapted to move said mandrel relative to said staple and said sleeve causing said staple to close on tissue located about a wound site; wherein said mandrel causing at least a portion of said staple to expand before causing said staple to close on said tissue.
Claim 3
Dependent Claim
25 words
A tissue stapler as claimed in claim 1 , said actuator mechanism comprising a cam for urging said sleeve to move relative to said mandrel.
Claim 4
Dependent Claim
44 words
The stapling device of claim 2 , further comprising a first cam follower coupled to said sleeve and a second cam follower coupled to said mandrel rod, said cam urging said first and second cam followers to move said sleeve relative to said mandrel.
Claim 5
Dependent Claim
24 words
The stapling device of claim 1 , wherein said mandrel causes the staple prongs to contract inward thereby deploying said staple into said tissue.
Claim 6
Dependent Claim
93 words
A stapler, comprising: a distal tip comprising a sleeve and a rod inserted into said sleeve, said rod comprising a flared distal tip; an actuator coupled to said sleeve and said rod, said actuator adapted to cause said sleeve to move relative to said rod; and a tissue staple comprising a plurality of tissue piercing prongs placed around said rod between said sleeve and said flared distal tip; wherein said movement of said sleeve relative to said rod causing said flared distal tip to expand said tissue piercing prongs away from said rod.
Claim 7
Dependent Claim
93 words
A stapler, comprising: a distal tip comprising a sleeve and a rod inserted into said sleeve, said rod comprising a flared distal tip; an actuator coupled to said sleeve and said rod, said actuator adapted to cause said sleeve to move relative to said rod; and a tissue staple comprising a plurality of tissue piercing prongs placed around said rod between said sleeve and said flared distal tip; wherein said movement of said sleeve relative to said rod causing said flared distal tip to expand said tissue piercing prongs away from said rod.
Claim 8
Dependent Claim
26 words
A stapler as claimed in claim 5 , wherein said movement of said sleeve relative to said rod causing said tissue piercing prongs to move together.
Claim 9
Dependent Claim
85 words
A process for closing a wound, comprising the steps of: inserting an introducer into a tissue wound, placing a sheath around the introducer and locating the sheath approximate to said wound, inserting the distal end of a stapler into said sheath to approach the tissue wound site, said stapler including a tissue staple on the distal end of said stapler, expanding a portion of the staple about said wound, and contracting at least a portion of said staple pulling the tissue surrounding the wound together.
Claim 10
Dependent Claim
85 words
A process for closing a wound, comprising the steps of: inserting an introducer into a tissue wound, placing a sheath around the introducer and locating the sheath approximate to said wound, inserting the distal end of a stapler into said sheath to approach the tissue wound site, said stapler including a tissue staple on the distal end of said stapler, expanding a portion of the staple about said wound, and contracting at least a portion of said staple pulling the tissue surrounding the wound together.
Claim 11
Dependent Claim
62 words
A process for closing a wound in an artery with a staple, comprising the steps of: inserting an introducer with a plurality of guide wires coupled thereto into an artery, guiding a stapler and staple to the wound site, expanding said staple to surround said wound site before entering said tissue, and closing said staple on said tissue to close said wound.
Claim 12
Dependent Claim
62 words
A process for closing a wound in an artery with a staple, comprising the steps of: inserting an introducer with a plurality of guide wires coupled thereto into an artery, guiding a stapler and staple to the wound site, expanding said staple to surround said wound site before entering said tissue, and closing said staple on said tissue to close said wound.
