Filed:

Jun 20, 1994

Appl. No.:

8/262203

Inventors:

Donald S. Kaplan - Weston CT
Matthew E. Hermes - Easton CT
Ross R. Muth - Brookfield CT
David L. Brown - Wallingford CT
Henry A. Holzwarth - Weston CT

Assignee:

United States Surgical Corporation - Norwalk CT

International Classification:

A61B 1706

US Classification:

206339

Abstract:

Synthetic absorbable sutures are filled with a stabilizing agent, preferably a mixture of glycerol and calcium lactate, and inserted into a retainer having a narrow convoluted passageway. The retainer is inserted into an open foil pouch with a package stabilizing element, such as a paper sheet filled with stabilizing agent. The package containing the suture, retainer and package stabilizing element is sterilized, aerated, equilibrated to a relatively high moisture level, and sealed. Long lengths of suture and doubled-over and tripled-over suture may be withdrawn from the retainer with low force without damaging the suture. Bends and kinks in the suture are prevented so as to provide a synthetic absorbable suture having highly desirable out of package hand and feel. The suture as removed from the package exhibits improved tissue drag characteristics.

Appl. No.:

7/117465

Inventors:

Donald S. Kaplan - Weston CT
Matthew E. Hermes - Norwalk CT
Ross R. Muth - Brookfield CT
John J. Kennedy - Stratford CT

Assignee:

United States Surgical Corporation - Norwalk CT

International Classification:

B29C 7102
A61F 202

US Classification:

264235

Abstract:

An absorbable, annealed surgical device made from a multi-phase, polymeric composition derived from lactide and glycolide is disclosed. Preferably, the composition has two phases, both phases are continuous, the first phase has about 0 - about 25% m glycolide moieties, the overall composition has up to 45% m glycolide moieties, and the first phase constitutes at least 50% (and preferably not more than about 95%) by weight of the composition. The device has a high distortion temperature, good resistance to hot-wet creep, but yet loses tensile strength in vivo guickly. The composition per se is injection-moldable, can be annealed, and is not brittle.

Appl. No.:

7/658681

Inventors:

Donald S. Kaplan - Weston CT
Matthew E. Hermes - Easton CT
Ross R. Muth - Brookfield CT

Assignee:

United States Surgical Corporation - Norwalk CT

International Classification:

A61B 1700

US Classification:

606228

Abstract:

A braided suture exhibits one or more improved properties, e. g. , reduced chatter, greater flexibility and/or better hand, than that of a braided suture of known, or standard, construction and of substantially equivalent size.

Assignee:

United States Surgical Corporation - Norwalk CT

International Classification:

C08G 6308

US Classification:

528354

Abstract:

A block copolymer for use in the fabrication of bioabsorbable articles such as monofilament surgical sutures is prepared by copolymerizing lactide and 1,4-dioxanone, and then polymerizing glycolide with the lactide/1,4-dioxanone copolymer.

C08G 6308

US Classification:

525411

Abstract:

Polymer blends of glycolide and/or lactide homopolymer and/or glycolide/lactide copolymer and polycaprolactone and/or polytrimethylene carbonate homopolymer or copolymers thereof and absorbable surgical devices manufactured therefrom having improved mechanical properties, such as improved impact resistance and improved cyclic flex, are disclosed. The blends may be prepared by polymerizing a glycolide or lactide containing polymer in the presence of a polymer derived from trimethylene carbonate or. epsilon. -caprolactone.
