SYSTEMS AND METHODS RELATED TO SELECTIVE HEATING OF CRYOGENIC BALLOONS FOR TARGETED CRYOGENIC NEUROMODULATION

摘要

Systems and methods related to selective heating of cryogenic balloons for targeted cryogenic neuromodulation are disclosed herein. A cryotherapeutic device configured in accordance with a particular embodiment of the present technology can include an elongated shaft having a proximal portion and a distal portion. The shaft can be configured to locate the distal portion in a vessel. The cryotherapeutic device can further include a cryoballoon extending from the distal portion and a plurality of heating elements arranged about the cryoballoon. The plurality of heating elements can be individually controlled to selectively deliver heat to tissue of a wall of the vessel proximate the outer surface of the cryoballoon.

1. A cryotherapeutic device, comprising:
an elongated shaft having a proximal portion and a distal portion, wherein the shaft is configured to locate the distal portion at a treatment site in a renal vessel; a cryoballoon affixed at the distal portion, the cryoballoon being configured to apply therapeutically-effective cooling to ablate tissue of a wall of the renal vessel; and a plurality of heating elements arranged about to the cryoballoon, wherein the plurality of heating elements are individually controllable to selectively deliver heat to tissue of a wall of the renal vessel proximate the cryoballoon.
