A heat exchanger is disclosed for causing cryolysis of adipose tissue of a human tongue. The heat exchanger includes a body having cooling channels for circulating fluids therein. The body forms a contact surface that contacts a portion of the dorsal surface of the tongue and a portion of the base of the tongue. The heat exchanger includes a pair of side walls extending from the body and forming a pair of side contact surfaces that are dimensioned so that they contact the dorsal and lateral surfaces of the tongue in a manner so as to constrict the tongue when the contact surface is in contact with the tongue. A method of treatment for apnea using the heat exchanger and/or administering a chemical adipolysis formulation/vasoconstriction agent is also disclosed.

Provided herein are catheter devices, systems, and methods to ablate a tissue location. The devises, systems, and methods disclosed herein include ablation systems including a catheter system with inner and outer shafts that deliver an ablation medium (e.g., a cryogenic ablation medium) to a body lumen and evacuate the ablation medium from the body lumen. In some embodiments, devices, systems, and methods disclose herein relate to monitoring and regulating pressure, temperature, or other conditions within a body lumen during an ablation procedure.

Provided herein is a multifunctional aesthetic system including a housing, an electromagnetic array situated in the housing and having one or more electromagnetic radiation (EMR) sources, a controller in electronic communication with the array to operate the one or more of the EMR sources to direct the EMR beam to a treatment area, and one or more sensors in electronic communication with the controller for providing feedback to the controller based on defined parameters to allow the controller to adjust at least one operating condition of the multifunctional system in response to the feedback.

System and methods of an electrosurgical controller having multiple modes of operation that are configured for treatment of a specific targeted tissue type and the electrosurgical effect desired where the treatment and effect are provided by a single controller and an electrosurgical probe. The electrosurgical controller includes an integrated fluid control apparatus or pump where activation of the controller allows for selective energy delivery and corresponding fluid volume flow rates. The electrosurgical probe includes a fluid transport lumen and is in communication with the controller and the pump for operation of the probe in the various user selected modes with accompanying energy delivery and fluid control directed to the desired treatment and surgical effect.

A medical device may comprise a handle having at least one actuator, a shaft having a proximal end, a distal end, and a lumen extending therebetween, the proximal end connected to the handle, the shaft including a distal articulable section including a distal tip, wherein the distal articulable section is configured to be articulated along a plane, a needle having a delivery lumen, the needle being movably positioned within the lumen of the shaft, and a vapor generator in fluid communication with the delivery lumen.

A system for creating separation between biological surfaces may comprise a hollow body configured for delivery of a fluid to a target location, a fluid supply in fluid-communication with the hollow body, a control element configured to control the delivery of a fluid through the hollow body, at least one first sensor configured to measure at least one parameter of the fluid flowing through the hollow body, at least one second sensor configured to measure at least one parameter of an environment of the hollow body, a feedback control module configured to receive information from one or more of the at least one first sensor or the at least one of the second sensor to control at least one operational function of the system.

In one embodiment, a medical system includes a catheter configured to be inserted into a chamber of a heart of a living subject, and including multiple electrodes configured to capture electrical activity from electrical activation signals propagating in tissue of the chamber, a display, and processing circuitry configured to automatically select bipolar signals to be captured into an electro-anatomical map from respective electrode pairs of the multiple electrodes responsively to an alignment of the respective electrode pairs with a direction of propagation of the electrical activation signals, and render the electro-anatomical map to the display.

The present disclosure includes catheter systems and methods for treatment of occlusions, including coronary artery chronic total occlusions. The catheter system comprises a catheter coupled to a control system with a distal end inserted into a patient and proximal to a location within a blood vessel with an occlusion. The catheter comprises a flexible outer sheath surrounding a housing with a plurality of lumens to perform various functions to penetrate occlusions.

An in vivo temperature control system has a monitor for the internal temperature of a biological organ such as the esophagus, and for directly controls the temperature in the organ side depending on the monitoring. The in vivo temperature control system includes: a catheter insertable into a living body; a temperature probe containing a temperature sensor, the probe being insertable into the catheter; a liquid storage section for storing a temperature-controlled liquid; a pump for supplying the liquid from the liquid storage section to the catheter; and a control section for controlling driving of the pump based on a signal detected from the temperature probe; wherein the control section controls the pump when the signal has reached a preset threshold, and the pump is driven such that the liquid in the liquid storage section is released to the outside through the catheter.

An adaptive flow rate control system for a surgical device, whereby the control system includes one or more nonintrusive sensors configured to be positioned on an aspiration conduit extending downstream from a handheld surgical device to measure flow and reduce clogging within the aspiration conduit is disclosed. The nonintrusive sensor may provide data to a controller of a handheld surgical device system to enable it to control operation of the handheld surgical device based at least in part on the data from the adaptive flow rate control system to prevent clogging of the aspiration system. The adaptive flow rate control system may also include a clog tracking module and a clog prediction module. The adaptive flow rate control system may include a wireless communication system configured to communicate with other components of a surgical device system and may communicate with a external network and resources on the internet.
