Beschreibung
Zusammenfassung:	A medical device (10, 110) includes a catheter shaft (11, 111) and can include an expandable balloon (18, 118) and a unitarily and continuously formed portion (108) having a varying durometer. One or both of the unitarily and continuously formed portion (108) and the balloon (18) are made from an irradiation cross-linked or cross-linkable mixture of a polyamide elastomer and at least one additional cross-linking reactant. L'invention concerne un dispositif médical (10, 110) comprenant un corps de cathéter (11, 111) et pouvant comporter un ballonnet gonflable (18, 118) ainsi qu'une partie unitaire et continue (108) équipée d'un duromètre variable. La partie unitaire et continue (108) et le ballonnet (18) ou l'un de ces deux éléments sont en mélange réticulé ou réticulable par irradiation d'élastomère polyamide et d'au moins un réactif additionnel de réticulation.
