Beschreibung
Zusammenfassung:	A direct visualization catheter includes an elongate shaft defining a lumen and having a distal end portion and a proximal end portion and a transparent balloon attached to the distal end portion of the shaft. The balloon includes a first layer comprising a thermoset polymer and a plurality of polymeric fibers at least partially embedded in the thermoset polymer and a second layer disposed on the first layer and comprising a hydrogel. L'invention concerne un cathéter de visualisation directe comprenant un axe allongé qui définit une lumière, et présente une partie d'extrémité distale et une partie d'extrémité proximale, et un ballonnet transparent qui est fixé à la partie d'extrémité distale de l'axe. Le ballonnet comprend une première couche composée d'un polymère thermodurci et d'une pluralité de fibres polymères au moins partiellement incorporées dans le polymère thermodurci, et une seconde couche disposée sur la première couche et comprenant un hydrogel.
