Title (EN) CRYOGENIC BALLOON WITH GREATER SIZE ADJUSTABILITY AT LOWER INFLATION PRESSURES
(FR) BALLONNET CRYOGÉNIQUE AVEC CAPACITÉ DE RÉGLAGE DE TAILLE SUPÉRIEURE À DES PRESSIONS DE GONFLAGE INFÉRIEURES
Abstract:
(EN) A balloon catheter (218) for an intravascular catheter system (210) includes a cryogenic balloon (236) 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 (236) 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 (236), and a ratio of outer diameter (in mm) of the cryogenic balloon (236) to inflation pressure (in psig) can be varied to form the desired cryogenic balloon (236).
(FR) La présente invention concerne un cathéter à ballonnet (218) pour un système de cathéter intravasculaire (210) comprend un ballonnet cryogénique (236) qui est formé d’un copolymère séquencé de mélange de polyuréthane et de polyamide. Les pourcentages de copolymère séquencé de polyuréthane et de polyamide peuvent varier. Par exemple, le ballonnet cryogénique (236) peut être formé de copolymère séquencé de plus de 50 % de polyuréthane et moins de 50 % de polyamide ; de copolymère séquencé de plus de 75 % de polyuréthane et moins de 25 % de polyamide ; ou de copolymère séquencé d’environ 85 % de polyuréthane et d’environ 15 % de polyamide. De plus, un rapport du changement de pression de gonflage (en psi) au changement de diamètre externe (en mm) du ballonnet cryogénique (236), et un rapport du diamètre externe (en mm) du ballonnet cryogénique (236) à la pression de gonflage (en psig) peuvent être modifiés pour former le ballonnet cryogénique souhaité (236).
