摘要:
A system for recanalizing an occluded blood vessel including a centering catheter employed to center an ablative guide wire within the blood vessel as the guide wire traverses the occlusion. The centering catheter includes a catheter body with an operative lumen through which the ablative guide wire is slidingly disposed. The centering catheter further includes a distally disposed centering mechanism that, when activated, centers the ablative guide wire within the blood vessel as it traverses the occlusion. The centering mechanism can comprise various embodiments including a single inflatable balloon or segmented inflatable balloon, which is in fluid communication with an inflation lumen. An airless preparation lumen may be disposed within the inflation lumen for ease of centering catheter preparation. The ablative guide wire includes insulation that is preferably formed of heat shrink tubing, which is stretched prior or concurrently with the heating process. The ablative guide wire includes a distal ablation tip having a non-traumatic structure and at least one discontinuous feature for creating high current densities for more efficient tissue ablation.

Substantially thermally sealed containers including flexible connectors joining an aperture in the exterior of the container to an aperture in a substantially thermally sealed storage region within the container are described. The flexible connectors include a duct forming an elongated thermal pathway between the exterior of the container and the substantially thermally sealed storage region within the container. The flexible connectors include compression units mated to each end of the duct and a plurality of compression strands connected between the compression units.

A combined imaging/HIFU probe includes an imaging scan head, a HIFU transducer, and an outlet port that delivers a flow of fluid across the HIFU transducer. At least a portion of the body cavity is filled with fluid in which the probe is immersed. The fluid provides a coupling for transmission of ultrasound energy between the probe and the patient. A flow of fluid may also be used to flush obstructions from an area of tissue near the HIFU transducer. Further described herein is a cuff to help retain fluid in the body cavity, a regulator to regulate fluid flow with respect to the body cavity according to a desired fluid pressure, and a cover for the HIFU transducer that has at least one perforation defined therethrough to allow fluid to flow through the cover. Further disclosed herein are methods of deploying a combined imaging/HIFU probe in a body cavity.
