Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
52 words
A surgical filament comprising a drawn and oriented copolyester comprising repeating divalent units of the formulas: wherein G represents the residue after removal of the hydroxyl groups of a dihydric alcohol, and wherein the divalent units (A) through (E) are bonded to each other by ester groups formed by linking said units.
Claim 2
Dependent Claim
52 words
A surgical filament comprising a drawn and oriented copolyester comprising repeating divalent units of the formulas: wherein G represents the residue after removal of the hydroxyl groups of a dihydric alcohol, and wherein the divalent units (A) through (E) are bonded to each other by ester groups formed by linking said units.
Claim 3
Dependent Claim
17 words
The surgical filament of claim 1 wherein G represents polymethylene of from 2 to 6 carbon atoms.
Claim 4
Dependent Claim
17 words
The surgical filament of claim 1 wherein the copolyester is a copolyester of glycolide and poly(1,3-propylene malonate).
Claim 5
Dependent Claim
17 words
The surgical filament of claim 1 wherein the copolyester is a copolyester of p-dioxanone and poly(1,3-propylene malonate).
Claim 6
Dependent Claim
21 words
The surgical filament of claim 1 in sterile condition and having at least one end thereof attached to a surgical needle.
Claim 7
Dependent Claim
21 words
The surgical filament of claim 2 in sterile condition and having at least one end thereof attached to a surgical needle.
Claim 8
Dependent Claim
21 words
The surgical filament of claim 3 in sterile condition and having at least one end thereof attached to a surgical needle.
Claim 9
Dependent Claim
21 words
The surgical filament of claim 4 in sterile condition and having at least one end thereof attached to a surgical needle.
Claim 10
Dependent Claim
46 words
A crystalline copolyester comprising repeating divalent units of the formulas: wherein G represents the residue after removal of the hydroxyl groups of a dihydric alcohol, and wherein the divalent units (A) through (E) are bonded to each other by ester groups formed by linking said units.
Claim 11
Dependent Claim
46 words
A crystalline copolyester comprising repeating divalent units of the formulas: wherein G represents the residue after removal of the hydroxyl groups of a dihydric alcohol, and wherein the divalent units (A) through (E) are bonded to each other by ester groups formed by linking said units.
Claim 12
Dependent Claim
16 words
The copolyester of claim 9 wherein G represents polymethylene of from 2 to 6 carbon atoms.
Claim 13
Dependent Claim
13 words
The copolyester of claim 9 comprising a copolyester of glycolide and poly(alkylene malonate).
Claim 14
Dependent Claim
13 words
The copolyester of claim 9 comprising a copolyester of p-dioxanone and poly(alkylene malonate).
Claim 15
Dependent Claim
