  • Patent number: 7048712
    Abstract: A combination of polymeric components provides desired characteristics in forming medical instruments such as catheters and balloons for dilatation catheters. For example, a balloon material is formed from a blend of polymeric components, including a first crystalline polymeric component and a second softening polymeric component. Where the first two components are generally incompatible, the balloon material can also include a third compatibilizing agent to facilitate blending the first two polymeric components together.

  • Patent number: 5849846
    Abstract: A catheter and/or balloon for a medical catheter is formed from a blend of polymeric components, including a first crystalline polymeric component and a second softening polymeric component. The polymeric material can also include a third compatibilizing agent to facilitate blending the first two polymeric components together. The first polymeric component can be a polyester or a polyamide, and the second polymeric component can be a polyolefin, or an ethylene copolymer. The third polymeric component is preferably an ethylene copolymer containing a reactive group that forms a covalent bond with the first polymeric component. The polymeric material forming the balloon or catheter also can include a catalyst to catalyze a reaction between the compatibilizing ethylene copolymer and the second polymer component.
