PLASTICIZED NYLON BALLOONS FOR MEDICAL DEVICES

摘要

A balloon for use in a medical device made of a material comprising a plasticized polyamide having a glass transition temperature of less than about 32 DEG C. The polyamide may be Nylon 11 or Nylon 12, the plasticizer may be N-n-butyl benzosulfonamide, and the material may also include a stabilizer. A method for making a balloon for use in a medical device including providing a tube made of a material comprising a plasticized polyamide; disposing the tube in a balloon mold; heating the tube to a temperature within the softening temperature range of the material; pressurizing the tube to conform it with the mold, thus producing a balloon; and removing the balloon from the mold. The method also includes cooling the balloon to within the setting temperature range of the material before removing the balloon from the mold.
