    摘要: Copolymers are prepared from 1,5-dioxepan-2-one and lactide and/or glycolide. The copolymers are useful in surgical applications such as sutures, suture lubricants, and allied surgical products. 1,5-Dioxepan-2-one is produced by a new process comprising first reacting ethylene glycol with an alkyl acrylate to form alkyl 3-(2-hydroxyethoxy)propionate, which is then cyclized by contacting with a trans-esterification catalyst.

    摘要: A synthetic absorbable hemostatic agent for use in the control of osseous hemorrhage, comprising a copolymer of lactide and glycolide containing from about 30% to 70% lactide on a molar basis, and having a molecular weight such that it possesses a putty-like consistency at room temperature. The preferred agent has a lactide/glycolide molar ratio of 65:35 and a molecular weight of between 2000 and 2500 Dalton. The agent may also be mixed with a biocompatible base.

    摘要: There is disclosed a wound closure tape comprising a nonwoven fabric having a pressure-sensitive adhesive uniformly disposed over one surface thereof. The tape is strong enough to hold minor wounds closed, and yet will conform to skin contours and will permit flexing and bending without undue restraint or detachment of the tape. The nonwoven fabric employed in the invention is a web of continuous filaments that are randomly oriented in the plane of the fabric, with the filaments being essentially free of bonding at cross-over points (that is, at points of intersection), and wherein the fabric is emboss bonded in an intermittent pattern.

    摘要: A synthetic absorbable hemostatic composition for use in the control of osseous hemorrhage, comprising polydioxanone in a biocompatible base, the polydioxanone having a sufficiently low inherent viscosity such that the composition possesses a putty-like consistency at room temperature. The preferred composition is one in which the polydioxanone comprises between 65% and 75% by weight of the composition.
