摘要： A cryoablation catheter for creating at least one lesion in tissue, the catheter having an elongate shaft with an intermediate section and a distal tip movable relative to the intermediate section. The catheter also includes at least one elongate control member extending along the intermediate section and secured to the distal tip where the elongate control member is movable relative to the intermediate section for causing movement of the distal tip relative to the intermediate section and at least one energy delivery member extending along the intermediate section to the distal tip where the at least one energy delivery member includes a linear first configuration and an elliptical second configuration. Manipulation of the control member adjusts the shape of the at least one energy delivery member.

摘要： An endovascular near critical fluid based cryoablation catheter for creating an elongate lengthwise-continuous lesion in tissue comprises an elongate shaft, a flexible distal tissue treatment section, and a distal tip. A plurality of flexible tubes extend through the distal treatment section to transport a near critical fluid to and from the distal tip. The distal treatment section is controllably deployed to match the contour of an anatomical region to be treated. In embodiments the distal treatment section includes a superelastic material and can assume a plurality of different shapes based on the distance ejected from an outer sleeve member. When the catheter is activated, heat is transferred between a target tissue and the distal treatment section of the catheter thereby creating the elongate lengthwise-continuous lesion in the tissue.
摘要翻译：用于在组织中产生细长的纵向连续损伤的血管内近临界流体基冷冻消融导管包括细长轴，柔性远端组织治疗部分和远侧末端。多个柔性管延伸穿过远端治疗部分以将近临界流体运送到远端和/或远离末梢。远端治疗部分被可控地部署以匹配待治疗的解剖区域的轮廓。在实施例中，远侧处理部分包括超弹性材料，并且可以基于从外套筒构件喷出的距离呈现多个不同形状。当导管被激活时，热量在目标组织和导管的远端治疗部分之间传递，从而在组织中产生细长的纵向连续损伤。

摘要： An endovascular near critical fluid based cryoablation catheter for creating an elongated lengthwise-continuous lesion in tissue can comprise an elongated shaft, a flexible distal tissue treatment section, and a distal tip. A plurality of flexible tubes can extend through the distal treatment section to transport a near critical fluid to and from the distal tip. The distal treatment section can also include a flexible fluid-sealed cover or barrier layer surrounding the delivery tubes. The cover and tubes can collectively define a space which is filled with a fluidic thermally conductive media. The thermally conductive media, fluid delivery tubes, and the cover can be arranged such that a flow of the near critical fluid through the tube bundle transfers heat between a target tissue and the distal treatment section of the catheter thereby creating the elongated lengthwise-continuous lesion in the tissue.
