Abstract
Abstract Bipolar electrosurgical scissors are disclosed having a pair of blades joined for relative movement in a scissor-like action between open and closed positions. At least one of the blades comprises a tissue contacting surface and first and second spaced apart electrodes extending along the surface. Current flow between the first and second electrodes promotes hemostasis in tissue contacting the surface. Preferably, each blade of the scissors includes first and second spaced-apart electrodes.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
87 words
Tissue cutting apparatus comprising: a pair of blades joined for relative movement in a scissors-like action between open and closed positions; each of said blades comprising a tissue contacting surface for contacting tissue, said contacting surface of each blade including first and second spaced apart electrodes extending along said surface, said electrodes being adapted for connection to a voltage source having a pair of terminals of opposite polarity; whereby current flow between said first and second electrodes of each blade promotes hemostasis in tissue contacting said surface.
Claim 2
Dependent Claim
87 words
Tissue cutting apparatus comprising: a pair of blades joined for relative movement in a scissors-like action between open and closed positions; each of said blades comprising a tissue contacting surface for contacting tissue, said contacting surface of each blade including first and second spaced apart electrodes extending along said surface, said electrodes being adapted for connection to a voltage source having a pair of terminals of opposite polarity; whereby current flow between said first and second electrodes of each blade promotes hemostasis in tissue contacting said surface.
Claim 3
Dependent Claim
15 words
Tissue cutting apparatus of claim 1 further comprising electrically insulative material disposed between said electrodes.
Claim 4
Dependent Claim
66 words
Tissue cutting apparatus of claim 1 wherein said first electrodes of each blade are adapted to be connected to one terminal of the voltage source so that they are of like polarity and said second electrodes of each blade are adapted to be connected to the other terminal of the voltage source so that they are of like polarity opposite to that of said first electrodes.
Claim 5
Dependent Claim
41 words
The tissue cutting apparatus of claim 1 wherein the first electrode of each blade is innermost and said innermost electrodes are adapted for connection to the same terminal of the voltage source so that said innermost electrodes are of like polarity.
Claim 6
Dependent Claim
21 words
The tissue cutting apparatus of claim 1 wherein said first and second electrodes are substantially co-extensive along said tissue contacting surface.
Claim 7
Dependent Claim
55 words
The tissue cutting apparatus of claim 1 wherein said first and second electrodes are disposed so that current flows between said first and second electrodes of each blade and between said first electrode of one blade and said second electrode of the other blade as said tissue contact surfaces are brought into proximity during cutting.
Claim 8
Dependent Claim
17 words
The tissue cutting apparatus of claim 1 wherein said tissue contacting surface comprises a tissue contacting edge.
Claim 9
Dependent Claim
28 words
The tissue cutting apparatus of claim 1 wherein said electrode surfaces are disposed so that current flows substantially between said first and second electrode surfaces of each blade.
Claim 10
Dependent Claim
35 words
The tissue cutting apparatus of claim 1 wherein said electrode surfaces are disposed so that current flows substantially between said first electrode surface of one blade and said second electrode surface of the other blade.
Claim 11
Independent Claim
131 words
A method for simultaneously cutting and promoting hemostasis of tissue comprising: providing tissue cutting apparatus comprising a pair of blades joined for relative movement in a scissor-like fashion between open and closed positions, each of said blades comprising a tissue contacting surface for contacting tissue located between said blades as said blades are moved together toward a closed position, the tissue contacting surface of each blade comprising first and second electrodes extending along the tissue contacting surface; placing tissue to be cut between said blades in contact with said tissue contacting surface of each blade; applying a voltage between the first and second electrodes of each blade so that current passes between said first and second electrode of each blade's tissue contacting surface; and closing the blades in a scissor-like action.
Claim 12
Independent Claim
131 words
A method for simultaneously cutting and promoting hemostasis of tissue comprising: providing tissue cutting apparatus comprising a pair of blades joined for relative movement in a scissor-like fashion between open and closed positions, each of said blades comprising a tissue contacting surface for contacting tissue located between said blades as said blades are moved together toward a closed position, the tissue contacting surface of each blade comprising first and second electrodes extending along the tissue contacting surface; placing tissue to be cut between said blades in contact with said tissue contacting surface of each blade; applying a voltage between the first and second electrodes of each blade so that current passes between said first and second electrode of each blade's tissue contacting surface; and closing the blades in a scissor-like action.
Claim 13
Dependent Claim
38 words
The method of claim 10 further comprising passing current between the first electrode of one blade and the second electrode of the other blade simultaneously with passing current between the first and second electrodes of the same blade.
