    摘要： Rapid exchange angioplasty catheters and methods of constructing rapid exchange angioplasty catheters including features that provide good pushability and kink resistance. In an illustrative embodiment, a catheter is provided, the illustrative catheter including a proximal hypotube section, which connects to a more distal braided catheter section. The braided catheter section connects to a midshaft portion that includes a guidewire entry port. Distal of the midshaft portion is a distal section having a cutting balloon disposed thereon. An inflation lumen extends the length of the catheter, while a guidewire lumen extends only from the guidewire entry port to the distal end of the catheter. Optionally, a core wire may extend across the joint from the hypotube, to the braided catheter section, and past the guidewire entry port.

    摘要： The invention relates to multi-layer medical balloons. In one aspect, a medical device includes an inflatable balloon. The inflatable balloon includes a first layer including a material having a first modulus of elasticity, and a second layer adjacent the first layer, the second layer including a material having a second modulus of elasticity that differs from the first modulus of elasticity by at least about 2,000 psi. A cutting element is carried by the balloon.

    摘要： A device for collapsing a balloon in the vasculature of a patient after an angioplasty procedure includes a balloon and at least one elastomeric member that is attached to the inner surface of the balloon at a plurality of attachment points. Preferably, the elastomeric member is an annular band that will stretch during balloon inflation. Consequently, when the balloon is deflated, the elastomeric member pulls on the balloon at its attachment points to return the balloon to a predetermined configuration, wherein the balloon collapses inwardly onto itself for subsequent removal of the balloon from the vessel.
