  • Assembly for adminstering IV solution
    Patent number: 4911691
    Abstract: An article, suitable for use as a body implant, is made from a novel composition comprising a multiple phase polymer composition comprising:(a) a first phase which comprises a substantially nonhydrophilic polymeric component; and(b) a second phase which comprises a hydrophilic polymeric component;said composition (i) being capable of absorbing water to an extent that it softens with a softening ratio of at least about 2:1 and/or swells with a swelling ratio of at least about 1.3:1; and (ii) when substantially completely hydrated has an energy to break of at least about 700 N-cm/cm.sup.3 and a 2.5% Secant modulus of less than about 7,000 N/cm.sup.2.
    Type: Grant
    Filed: August 18, 1987
    Date of Patent: March 27, 1990
    Assignee: Menlo Care, Inc.
