Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
76 words
A sterile surgical staple for use with a stapling instrument in closing a wound of human or animal skin comprising a pair of legs joined at one end by a crown with substantially the entire surface of said staple coated with a polymeric silicone material whereby it is easier to place said staple in said skin to close a wound and it is easier to remove said staple from said skin when the wound has healed.
Claim 2
Dependent Claim
76 words
A sterile surgical staple for use with a stapling instrument in closing a wound of human or animal skin comprising a pair of legs joined at one end by a crown with substantially the entire surface of said staple coated with a polymeric silicone material whereby it is easier to place said staple in said skin to close a wound and it is easier to remove said staple from said skin when the wound has healed.
Claim 3
Dependent Claim
11 words
The staple of Claim 1 wherein the silicone is polydimethyl siloxane.
Claim 4
Dependent Claim
16 words
or Claim 2 3. The staple of Claim 1/wherein the legs are perpendicular to the crown.
Claim 5
Dependent Claim
23 words
any one of to 3 4. The staple of/Claimsl/wherein substantially the entire surface of each staple is coated with a polymeric silicone material.
Claim 6
Dependent Claim
90 words
A surgical stapling instrument for implanting and forming surgical staples in the skin or fascia of a patient, said instrument comprising a body, means for driving staples disposed in said body, means for forming staples as they are driven disposed within said body, a magazine for carrying a plurality of staples mounted on said body and means for sequentially feeding staples from said magazine to said means for driving and forming the staples, the improvement comprising substantially the entire surface of said staples being coated with a polymeric silicone material.
Claim 7
Dependent Claim
90 words
A surgical stapling instrument for implanting and forming surgical staples in the skin or fascia of a patient, said instrument comprising a body, means for driving staples disposed in said body, means for forming staples as they are driven disposed within said body, a magazine for carrying a plurality of staples mounted on said body and means for sequentially feeding staples from said magazine to said means for driving and forming the staples, the improvement comprising substantially the entire surface of said staples being coated with a polymeric silicone material.
Claim 8
Dependent Claim
13 words
The improvement according to Claim 5 wherein the silicone material is polydimethyl siloxane.
Claim 9
Dependent Claim
16 words
The improvement according to Claim 5/wherein each staple comprises a pair of legs and a crown.
Claim 10
Dependent Claim
20 words
The improvement according to Claim 7 wherein the legs of the staples are perpendicular to the crown of the staple.
Claim 11
Dependent Claim
118 words
An adhered array of sterile surgical staples for use with a stapling instrument in closing a wound of human or animal skin, comprising a plurality of individual surgical staples, each staple comprising a pair of legs joined together at one end by a crown, said staples being disposed in abutting relationship with adjacent staples having their legs and crown touching, said staples being adhered together to form an integral array by a polymeric silicone material, the legs of individual staples being coated with a polymeric silicone material whereby it is easier to place said staple in said skin to close a wound and it is easier to remove said staple from said skin when the wound is healed.
Claim 12
Dependent Claim
118 words
An adhered array of sterile surgical staples for use with a stapling instrument in closing a wound of human or animal skin, comprising a plurality of individual surgical staples, each staple comprising a pair of legs joined together at one end by a crown, said staples being disposed in abutting relationship with adjacent staples having their legs and crown touching, said staples being adhered together to form an integral array by a polymeric silicone material, the legs of individual staples being coated with a polymeric silicone material whereby it is easier to place said staple in said skin to close a wound and it is easier to remove said staple from said skin when the wound is healed.
Claim 13
Dependent Claim
26 words
An array of staples according to Claim 9 wherein the crowns of the staples are coated with a polymeric silicone material to form an integral array.
Claim 14
Dependent Claim
32 words
or Claim 10 11. An array of staples according to Claim 9 / wherein substantially the entire exposed surface of each staple in the array is coated with a polymeric silicone material.
Claim 15
Dependent Claim
