Devices for therapeutic nasal neuromodulation and associated methods and systems

A device for therapeutic neuromodulation in a nasal region can include, for example, a shaft and a therapeutic element at a distal portion of the shaft. The shaft can locate the distal portion intraluminally at a target site inferior to a patient's sphenopalatine foramen. The therapeutic element can include an energy delivery element configured to therapeutically modulate postganglionic parasympathetic nerves at microforamina of a palatine bone of the human patient for the treatment of rhinitis or other indications. In other embodiments, the therapeutic element can be configured to therapeutically modulate nerves that innervate the frontal, ethmoidal, sphenoidal, and maxillary sinuses for the treatment of chronic sinusitis.

Directional cryoablation system
11690663 · 2023-07-04 · ·

A cryoablation system is provided that can assume a directional activated state and includes a cryoablation probe and a controller. The cryoablation probe has an active region that includes a cooling compartment and an opposing heating compartment that are thermally insulated from one another to minimize energy losses therebetween such that ice is selectively and directionally formed at the target site. The cooling compartment can include a temperature sensor and an exhaust tube to guide a fluid or gas that exhibits a Joule Thomson cooling effect through the probe. The heating compartment can include a temperature sensor and a heater cartridge having a heater zone. The controller of the cryoablation system can process temperature measurement data from the sensors of the heating and cooling compartments and regulate the heater zone based on the temperature measurement data processing to maintain a temperature that is sufficiently constant to mitigate or prevent formation of ice on the heating compartment.

Cryocatheter with single phase coolant fluid cooled thermoelectric module and cerebral medical procedures employing local ice ball

Cryocatheter including an elongated flexible catheter member having a short rigid catheter tip for introduction into a therapy site and a heat exchange arrangement for freezing the catheter tip to a cryo-temperature from between about −15° C. to about −30° C. for freezing human tissue at the therapy site. Cerebral medical procedures include inter alia employing a local ice ball for sealing a bleeding rupture in an arterial wall in the case of a stroke hemorrhage, employing a local ice ball for mapping electrical disorder foci in a brain, for example, epileptic foci, and the like.
