Beschreibung
Zusammenfassung:	A balloon catheter capable of delivering torque and pushing through obstructions includes a relatively weak balloon segment of a catheter and rotatable asymmetric tip. A reinforcement sleeve increases column strength and torque transmission to push the balloon and rotate the tip to facilitate passage through said obstructions. The tip is preferably asymmetric around its axis, usually being beveled, and the reinforcement slide includes a slide lock mechanism which increases shaft flexibility after balloon deployment. La présente invention concerne un cathéter à ballonnet capable de transmettre un couple et de pousser à travers des obstructions qui comprend un segment de ballonnet relativement faible d'un cathéter et une pointe asymétrique rotative. Une gaine de renforcement augmente la résistance en colonne et la transmission de couple pour pousser le ballonnet et faire tourner la pointe pour faciliter le passage à travers lesdites obstructions. La pointe est de préférence asymétrique autour de son axe, qui est généralement biseauté, et la glissière de renforcement comprend un mécanisme de verrouillage de coulissement qui augmente la flexibilité de la tige après le déploiement du ballonnet.
