    摘要: A multiple balloon catheter for use in a vessel of a patient and for use with an inflation/deflation device. A flexible elongate tubular member with proximal and distal extremities has a distal balloon mounted on the distal extremity of the flexible elongate tubular member. Coaxial inner and outer balloons are mounted on the distal extremity of the flexible elongate member proximal of the distal balloon. The flexible elongate tubular member has balloon inflation lumens therein in communication with the interiors of the distal balloon and the inner and outer coaxial balloons. A manifold is secured to the proximal extremity of the flexible elongate tubular member in communication with the inflation lumens and is adjusted to be coupled to the inflation/deflation device. Valves are carried by the inflation/deflation manifold for inflating the distal balloon in the inner and outer coaxial balloons one at a time or in unison without removal of the inflation/deflation device from the manifold.

    摘要: An intravascular catheter provides means for infusing an agent into a treatment site in a body lumen and means for deploying the infusing means adjacent the treatment site which operate independently of one another. In a first embodiment, a flexible catheter body has an expansion member attached to its distal end in communication with an inflation passage, and an infusion array disposed about the expansion member in communication with one or more delivery passages. In a second embodiment, the infusion array is a separate component and slidably received over the expansion member, which may be a balloon dilatation catheter. In both embodiments, the infusion array includes a plurality of delivery conduits having laterally oriented orifices. The delivery conduits may be extended radially from the catheter body to contact a treatment site by expanding the expansion member with an inflation fluid. An agent may be introduced into the delivery passages and infused into the treatment site through orifices in the delivery conduits. The expansion member may be expanded for dilatation of the lumen before, during, or after infusion.
