The present invention is an ablation device having a flexible and resilient shaft that can provide fluid to the site of ablation from a plurality of different fluid sources.

Systems and methods for controlling an irrigation flow rate during a lithotripsy procedure are provided. The system includes a laser configured for lithotripsy procedure, a lithotripsy irrigation system, and a temperature sensor configured to provide input to enable control of a flow of the lithotripsy irrigation system in response to a change in temperature from the operation of the laser.

A catheter includes a first tubular portion provided with a first opening communicating with an interior of the first tubular portion; a second tubular portion passing through the first tubular portion, the second tubular portion having an extension extending from a leading end of the first tubular portion and provided with a second opening communicating with an interior of the second tubular portion; and a temperature sensor configured to measure temperature of a measuring unit placed in the extension of the second tubular portion, wherein the catheter is configured to collect fluid discharged from one of the first opening and the second opening from another one of the first opening and the second opening.

Neuromodulation catheter systems with controlled irrigation capabilities and methods for using such systems are disclosed herein. One such method includes, for example, positioning an irrigated neuromodulation catheter at a treatment site within a renal blood vessel of a human patient, delivering neuromodulation energy at the treatment site, and delivering irrigation fluid to the treatment site having characteristics coordinated with the delivered energy. The characteristics can be adjusted to maintain an energy delivery element and/or tissue of the blood vessel at a constant temperature as power is increased. The method can further include monitoring at least one parameter of the tissue and/or of the energy delivery element, and adjusting the neuromodulation energy and/or the characteristics of the irrigation fluid if the at least one parameter falls outside of a treatment range of values.

A laser light irradiation system that irradiates a stone in a body with laser light to cause the stone to be dust, the laser light irradiation system including a laser fiber that emits the laser light, and a processor configured to control a frequency of the laser light emitted from the laser fiber, wherein the processor is configured to switch between first laser light of a first frequency and second laser light of a second frequency such that the second laser light is emitted at least before or after an emission timing of the first laser light, the first laser light generating a water flow that pulls the stone toward the laser fiber, the second laser light generating a water flow that stirs the stone.

Systems and methods for controlling energy delivered to an area of tissue during a treatment procedure are provided. The system includes a device for delivering energy to the area of tissue; an energy generator for generating and supplying energy to the device; and a controller for controlling an amount of energy generated by the energy generator and delivered to the area of tissue by the device. Controlling the amount of energy delivered to the area of tissue alters a primary zone of the area of tissue to a first level, alters a secondary zone to a second level, alters a tertiary zone to a third level, or a combination thereof, where the first level, the second level, the third level, or a combination thereof is predetermined, and where a coverage area of the primary zone, the secondary zone, the tertiary zone, or a combination thereof is also predetermined.

A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to heat tissue to create lesions without ablating the tissue. The system includes a first treatment device having at least one electrode for applying radiofrequency energy to tissue, a controller including a connector to which a first treatment device is coupled for use, and a generator for applying radiofrequency energy to the electrodes. The controller controls application of energy so that the tissue is thermally treated to create lesions but preventing thermal treatment beyond a threshold which would ablate the tissue.

A suction or other component of an endoscope system may be cycled on and off or otherwise controlled without requiring direct user input, such as automatically or semi-automatically using a current or historical state of a laser generator, a blurriness or other information from an image of the working area, a count of fragments of a calculi stone, an intraoperative pressure, an intraoperative temperature, or one or more other characteristics of the laser generator or the targeted calculi stone.

A vapor delivery system and method is provided that is adapted for treating prostate tissue. The vapor delivery system includes a vapor delivery needle configured to deliver condensable vapor energy to tissue. In one method, the vapor delivery system is advanced transurethrally into the patient to access the prostate tissue. The vapor delivery system includes a generator unit and an inductive heating system to produce a high quality vapor for delivery to tissue. Methods of use are also provided.

A vapor delivery device includes an induction coil system. The induction coil system can include a coiled fluid tube, a coiled wire, a capsule between the coiled fluid tube and the wire, and a cooling fluid supply configured to force a cooling fluid through the capsule across the coiled wire. The induction coil system can include a closed loop ferrite core, a wire coiled around a first portion of the ferrite core, and a fluid tube coiled around a second portion of the ferrite core. A wire coil can be contained in a cartridge system removably coupleable to a disposable vapor delivery device. The system can include a fluid flow controller and induction power regulation to maintain a specific operating pressure range for vapor within a uterus or other bodily cavity, tract, or duct.
