An electrode unit comprises: an electrode supporting member provided with a pair of distal end rigid members surfaces of which are covered by an electrically insulating material; a treatment electrode configured with electrode bodies arranged in respective distal end portions of the pair of distal end rigid members and protruding downward respectively from the pair of distal end rigid members, and a spanning portion that spans respective lower end portions of the electrode bodies; and a detection sensor arranged on respective proximal end sides of the pair of distal end rigid members and configured to detect a contact state between the pair of distal end rigid members and tissue.

A microneedling system may reciprocate a plurality of microneedles disposed on a handpiece into the skin of a patient. The microneedles and/or electrode plates may deliver RF energy to the patient for inducing collagen coagulation and regeneration. An interrogative modality such as ultrasound may combined into the microneedling handpiece or used as a separate instrument to interrogate the skin and identify or measure the thicknesses of constituent layers. The data obtained from the interrogative modality may be displayed and can be used to automatically adjust operating parameters of the microneedling device, including the penetration depth of the needles, the pulse duration, and/or the power level of the RF energy to optimize the treatment for the specific patient and/or condition being treated. The microneedling system may recall the skin measurements for distinct sectors of the skin which are expected to have different properties.

A system for cutting leaflet tissue at a cardiac valve may comprise a guide catheter having a proximal end and a distal end, wherein the distal end of the guide catheter is steerable to a position above a cardiac valve. The system may also include a handle coupled to the proximal end of the guide catheter, the handle comprising at least one control configured to steer the guide catheter to the position above the cardiac valve. Finally, the system may comprise a cutting mechanism routable through the guide catheter and able to be positioned at the distal end of the guide catheter, the cutting mechanism configured to cut a portion of leaflet tissue of the cardiac valve.

Flexible apparatus for ablating unhealthy spinal tissue. A housing includes a distal end and a proximal end. Multiple thermocouples mounted on the housing measure spinal tissue temperatures at locations between the proximal end and the distal end. A sensor measures spinal tissue impedance. The measured spinal tissue impedance corresponds to various physical state data of the spinal tissue. The spinal tissue impedance and the spinal tissue temperatures are displayed to the surgeon, enabling the surgeon to determine with certainty the location of the unhealthy spinal tissue, and to exercise control over the ablation apparatus. Nerve stimulation by IMP/STM switch system to detect nerve responses before and after treatment.

Luminal organ sizing devices and methods. In a method of the present disclosure, the method includes performing a valve replacement procedure using a valve device positioned within a valve annulus or opening of a luminal organ while a system including a balloon configured for inflation is at least partially introduced into a luminal organ so that the balloon is adjacent to a valve annulus or opening.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed. The method comprises the steps of gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical instrument, analyzing the gathered data to determine an appropriate operational adjustment of the surgical instrument, and adjusting the operation of the surgical instrument to improve the operation of the surgical instrument.

A system includes a surgical instrument configured to perform a laparoscopic surgical operation, a location sensor configured to identify a spatial relationship between an anatomical structure and the surgical instrument, and a processor configured to receive a graphical representation of a patient, determine proximity of the distal end portion of the surgical instrument with the anatomical structure of the patient based on the spatial relationship, and generate a warning based on the determination of proximity.

Systems, devices, and methods for electroporation ablation therapy are disclosed, with a protection device for isolating electronic circuitry, devices, and/or other components from a set of electrodes during a cardiac ablation procedure. A system can include a first set of electrodes disposable near cardiac tissue of a heart and a second set of electrodes disposable in contact with patient anatomy.

The device includes an elongated hollow body formed by a first member and a second member. The second member is capable of rotating relative to the first member. The hollow body has an internal cavity, a front end, a rear end, an external surface, and an electrical wire arranged within the body. The hollow body is configured to reversibly receive the third portion of the electrode at the front end of the body such that electrical contact is made between the electrode and the electrical wire and the second portion of the electrode is not surrounded by the hollow body. The device includes a first button, a vacuum tube and a vacuum outlet.

A control device for use with a treatment tool that includes a heating element to apply heat to a treatment target. The control device comprises a processor configured to set a target temperature for the heating element and to control the heating element so that temperature of the heating element follows the target temperature. The processor is configured to switch the control of the heating element from a first phase to a second phase. A first followability of the temperature of the heating element in the first phase is higher than a second followability of the temperature in the second phase. The processor is configured to terminate the controlling of following the temperature of the heating element to the target temperature when a parameter is beyond a predetermined range wherein the parameter being defined as a fluctuation between the temperature of the heating element and the target temperature.
