AI Technical Summary

Problems solved by technology

However, current systems mainly rely on a natural cooling process, which prolongs the treatment time
Alternatively, current medical methods flush the area with fluid, but require the use of separate medical tools, thereby complicating the procedure and also prolonging treatment time

Embodiment Construction

[0178] In various embodiments, the ablation devices and catheters described herein are compatible with U.S. Patent 9,561,068 filed on January 12, 2015, entitled "Method and Apparatus for Tissue Ablation" and filed on February 7, 2017. Any one or more of the heating systems described in Published US Patent Application 14 / 594,444, which is hereby incorporated by reference in its entirety, is used in conjunction.

[0179] "Treatment" and variations thereof refer to any means of reducing the extent, frequency or severity of one or more disorders or signs associated with a condition.

[0180] "Duration" and variants thereof refer to the course of time over which treatment is administered as prescribed, ie, from beginning to end, regardless of whether treatment ends because the condition in question is resolved or treatment is suspended for any reason. During the duration of the treatment, a plurality of treatment phases may be prescribed during which one or more prescribed stimuli ...

Abstract

Ablation catheters and systems include coaxial catheter shafts with an inner lumen for delivering an ablative agent and an outer lumen for circulation of a cooling element about the catheter. Induction heating is used to heat a chamber and vaporize a fluid within by wrapping a coil about a ferromagnetic chamber and providing an alternating current to the coil. A magnetic field is created in the area surrounding the chamber which induces electric current flow in the chamber, heating the chamber and vaporizing the fluid inside. Positioning elements help maintain the device in the proper positionwith respect to the target tissue and also prevent the passage of ablative agent to normal tissues.

Description

[0001] cross reference [0002] This application claims U.S. Provisional Patent Application 62 / 425,144, filed November 22, 2016, entitled "Methods and Systems for Ablation" and U.S. Provisional Patent Application 62 / 42, filed May 19, 2016, entitled "Cooled Coaxial Ablation Catheter" 338,871 priority. [0003] This application is also a continuation-in-part of U.S. Patent Application 15 / 144,768, filed May 2, 2016, entitled "Induction-Based Micro-Volume Heating System," which was filed January 12, 2015, and titled "Method and Apparatus for Tissue Ablation," and a continuation-in-part of U.S. Patent Application 14 / 594,444, published on Feb. 7, 2017 as U.S. Patent 9,561,068, which was filed on Jan. 17, 2014 with the same title and A continuation-in-part of US Patent Application 14 / 158,687, published on February 7, 2017 as US Patent 9,561,067, which in turn is dependent on the identically titled US Provisional Patent Application 61 / 753,831, filed January 17, 2013.
