A medical device, such as a catheter, catheter balloon, stent, blood filter, endoscope or portion thereof, comprises a segmented polymer, having a plurality of hard segments and a plurality of soft segments. The polymer hard segments have a substantially uniform molecular weight distribution. The molecular weight distribution ratio, Mw/Mn, may be 1.5 or less.
L'invention concerne un dispositif médical, tel qu'un cathéter, un ballonnet de cathéter, un stent, un hémofiltre, un endoscope ou une partie de celui-ci, dispositif comprenant un polymère segmenté, ayant une pluralité de segments durs et une pluralité de segments mous. Les segments durs du polymère ont une distribution de poids moléculaire uniforme. Le rapport de distribution de poids moléculaire, Mw/Mn peut être égal ou inférieur à 1,5.
