摘要:
A synthetic absorbable monofilament comprising glycolide and epsilon caprolactone is provided. The monofilament exhibits physical characteristics equivalent to or superior than gut sutures. The monofilaments can be fabricated into a wide variety of surgical devices such as sutures, meshes, and the like.
摘要:
A method for making bioabsorbable block copolymer includes extruding a mixture of first polymeric component particles with second polymeric component particles under conditions sufficient to cause transesterification. The resulting block copolymer filaments can be used to form surgical sutures.
摘要:
A coated gut suture is prepared by applying a moisture-retaining substance to the gut suture, followed by coating the suture with a synthetic bioabsorbable polymer. A particularly useful moisture-retaining substance is glycerol. The synthetic bioabsorbable polymer contains a epsilon-caprolactone as the major constituent. The gut suture can be packed in the absence of conventional tubing fluid while retaining flexibility, pliability, and resistance to fray.
摘要:
Degradable polyesteramide suitable for use in biomedical applications is obtained by reacting diamino alkyl ester with alpha hydroxy acid to form diamide-diol which is reacted with acyl halide or dicarboxylic acid to yield polyesteramide. ##STR1##
摘要:
A method of treating a polymer involves contacting the polymer with a supercritical fluid under conditions of temperature and pressure to incorporate the supercritical fluid in the polymer and thereby effectuate an increase in plasticity and/or elasticity of the polymer. In a particular embodiment, the treated polymer is a biocompatible polymer which is fabricated into a medical device or part thereof.
摘要:
Absorbable copolymers are fabricated from a predominant component of dioxanone randomly copolymerized with minor amounts of other bioabsorbable monomers. The copolymers are useful in forming surgical articles, including both monofilament and multifilament sutures.
摘要:
Block copolymers wherein one of the blocks is made from hard phase forming monomers and another of the blocks is made from soft phase forming monomers copolymerized with randomly intermingled units of other soft phase forming monomers. The copolymers are useful in forming surgical articles, including both monofilament and multifilament sutures.
摘要:
A bioabsorbable copolymer is obtained from the polymerization of a major amount of .epsilon.-caprolactone and a minor amount of at least one other copolymerizable monomer in the presence of an initiator possessing at least two carboxylic acid groups. The copolymer is useful, inter alia, as a coating for a surgical suture.
