  • Polyurethane/polyisoprene blend catheter
    Patent number: 8795573
    Abstract: A medical article, such as a catheter, is formed from a blend of polyurethane and synthetic polyisoprene (SPIR). The blended medical article is preferably selected and prepared to be relatively rigid at room temperature and relatively flexible at body temperature. An intermittent catheter made from the blend provides a degree of stiffness for its insertion into the patient at room temperature. The catheter becomes softer, and therefore more comfortable, at warmer temperatures (e.g., body temperature) which reduce discomfort after insertion. Optionally, the catheter or a portion thereof can have a hydrophilic coating as to avoid the need for external lubricants. Advantageously, the blended catheter can meet the stiffness, tensile strength, and coefficient of friction requirements of intermittent catheterization applications while avoiding the risk of toxic or allergic reactions in sensitive users.
    Type: Grant
    Filed: June 30, 2009
    Date of Patent: August 5, 2014
    Assignee: C.R. Bard, Inc.
    Inventors: Ronald L. Bracken, Fung Bor Chen, Randy Tuck
  • Synthetic polyisoprene foley catheter
    Patent number: 8633268
    Abstract: An indwelling urinary drainage catheter (12, 110) includes synthetic polyisoprene rubber (SPIR). Advantageously, the SPIR catheter can meet the tensile and resiliency requirements of Foley applications while avoiding the risk of allergic reactions in sensitive patients. The SPIR comprises an accelerator system that uses a carbamate as the only accelerator, a guanidine as the only accelerator, a combination of guanidine and carbamate accelerators, a combination of carbamate and thiazole accelerators, or a combination of guanidine, carbamate and thiazole accelerators.
