    摘要: A flexible drive cable comprises a flexible cable body, a pair of electrically insulated wires disposed through an axial lumen of the cable body, and a resilient support tube disposed over the wire pair. The resilient support tube provides support for the wire pair to help the wire pair recover from bending and deformation which may occur during storage or use of the drive cable. The support tube is usually liquid impermeable to maintain an air gap around the wire pair. The air gap improves shielding and maintains a constant overall impedance across the drive cable. The drive cable may be combined with an ultrasonic transducer at its distal end to form an ultrasonic transmission core.

    摘要: In one aspect, the invention provides a vascular catheter sheath for use with a therapeutic catheter having a radially expandable member. The catheter sheath includes a catheter body having a proximal end, a distal end, and at least one lumen adapted to receive the therapeutic catheter. The catheter body further includes a compliant portion near the distal end, with the compliant portion being adaptable to conform to the shape of the expandable member when the expandable member is radially expanded in the lumen.

    摘要: A catheter system for localized or semi-localized administration of agents through the wall of a blood vessel is provided. Various catheter system constructions which use at least one expandable occluding device to create an isolated region are provided. Constructions using one catheter and one occlusion device are provided, along with constructions using two catheters and multiple occlusion devices. The catheter system may include a catheter with a variable stiffness along its length. The catheter system may also include a guide wire integrated with an inner catheter. The catheter can infuse the agent into the blood vessel in a pressure regulated manner. Methods for delivery and infusion of the agent within a blood vessel are also provided.
