Appl. No.:

17/349535

Inventors:

- Somerville NJ, US
Christopher DeFelice - Springfield NJ, US

Assignee:

Ethicon, Inc. - Yuyao City

International Classification:

A61L 17/12
A61L 17/00
A61L 17/14
C08G 63/64
A61B 17/06

Abstract:

Novel surgical sutures and novel medical devices made from novel semi-crystalline, glycolide-rich A-B-A triblock copolymers of glycolide and lactide, wherein said B-segment is a fully amorphous random copolymer of glycolide and lactide, for long term medical applications are disclosed. The novel polymer compositions are useful for long term absorbable surgical sutures, meshes and other medical devices, especially for patients with compromised healing. The novel sutures have improved properties and improved breaking strength retention, while still substantially absorbing within about a 120-day period post-implantation.

International Classification:

C08L 67/04
A61L 31/14
A61L 31/04

Abstract:

Novel absorbable polymeric blends having bimodal molecular weight distribution are disclosed. The bimodal blends have a first component that is a polylactide polymer or a copolymer of lactide and glycolide having a bimodal molecular weight distribution, and a second component that is a poly(p-dioxanone) polymer of unimodal or bimodal molecular weight distribution. Alternately, the bimodal blends have a first component that is a polylactide polymer or a copolymer of lactide and glycolide having a unimodal molecular weight distribution, and a second component that is a poly(p-dioxanone) polymer of bimodal molecular weight distribution. The novel polymeric bimodal molecular weight blends provide medical devices having improved dimensional stability. Also disclosed are novel absorbable medical devices made from these novel bimodal polymer blends, as well as novel methods of manufacture.
