Abstract
A balloon catheter for an intravascular catheter system includes a cryogenic balloon that is formed from a blend of polyurethane and polyamide block copolymer. The percentages of polyurethane and polyamide block copolymer can vary. For example, the cryogenic balloon can be formed from greater than 50% polyurethane and less than 50% polyamide block copolymer; greater than 75% polyurethane and less than 25% polyamide block copolymer; or approximately 85% polyurethane and approximately 15% polyamide block copolymer. Additionally, a ratio of a change in inflation pressure (in psi) to a change in outer diameter (in mm) of the cryogenic balloon, and a ratio of outer diameter (in mm) of the cryogenic balloon to inflation pressure (in psig) can be varied to form the desired cryogenic balloon.
