Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
29 words
A METHOD OF PREPARING A SUTURE COMPRISING COATING A SURGICAL STRUCTURE FIBER WITH A CASTING SYRUP OF HYDROXYETHYL OR HYDROXYPROPYL ACRYLATE AND THEN COMPLETING THE POLYMERIZATION OF THE ACRYLATE.
Claim 2
Independent Claim
29 words
A METHOD OF PREPARING A SUTURE COMPRISING COATING A SURGICAL STRUCTURE FIBER WITH A CASTING SYRUP OF HYDROXYETHYL OR HYDROXYPROPYL ACRYLATE AND THEN COMPLETING THE POLYMERIZATION OF THE ACRYLATE.
Claim 3
Dependent Claim
15 words
A method according to claim 1 wherein the casting syrup contains partially polymerized hydroxyethyl acrylate.
Claim 4
Dependent Claim
14 words

Claim 5
Dependent Claim
33 words
A method according to claim 3 wherein the cross-linking agent is a glycol diacrylate or methacrylate present in an amount up to 15 percent of the weight of said hydroxyethyl acrylate or methacrylate.
Claim 6
Independent Claim
53 words
A method of preparing a suture comprising coating a surgical suture fiber with a casting syrup of hydroxyethyl or hydroxypropyl acrylate or methacrylate, wherein said casting syrup includes a medicinally active substance which is releasably adsorbed in the acrylate or methacrylate during the polymerization and then completing polymerization of the acrylate or methacrylate.
Claim 7
Independent Claim
