  • Patent number: 4440789
    Abstract: 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.

  • Patent number: 4415388
    Abstract: Particulate absorbents of a water-insoluble water-swellable polymer having a gel capacity of at least 10 are immobilized with a composition comprising the absorbent in a liquid polyhydroxy organic compound. The composition may be employed by applying to an appropriate surface and subjecting the liquid film to solidifying conditions. The solidified film product has high absorptive capacity and is free of undesirable movement when positioned in absorbent articles. A foam product having both absorptive and cushioning properties is prepared from a solid, particulate, water-insoluble, water-swellable polymer having a gel capacity of at least 10, a solid, particulate blowing agent, and a liquid polyhydroxy organic compound.
