The present disclosure relates to methods, devices, kits and systems for enhancing the efficacy and longevity of denervation procedures.

A device for treating tissue includes a catheter including an elongated body extending from a proximal end to a distal end and including a lumen extending therethrough, a distal tip connected to the distal end of the elongated body and including a first electrode and a second electrode extending thereabout, the first electrode extending to a distal opening of the lumen and a first needle extending longitudinally from a proximal end to a distal end, the first needle slidably received within the lumen of the catheter to be moved between a retracted bipolar configuration, in which the distal end of the needle is proximal the distal opening of the catheter, and an extended monopolar configuration, in which the distal end of the first needle extends distally past the distal opening of the catheter so that the first needle contacts the first electrode and is configured to cut tissue.

An ultrapolar electrosurgery blade and an ultrapolar electrosurgery pencil. The ultrapolar electrosurgery blade has a non-conductive planar member with opposing planar sides, a cutting end, and an opposite non-cutting end, first active and return electrodes located on one opposing planar side, and second active and return electrodes located on the other opposing planar side.

A method for treating hypertrophic cardiomyopathy (HCM) utilizes an RF ablation electrode needle system that has an RF ablation generator, and an electrode needle. The electrode needle is introduced to puncture within myocardium and to reach the hypertrophic area of the interventricular septum. The RF ablation generator is then turned on to implement single-point or multi-point ablation on the hypertrophic area of the interventricular septum, and then the RF electrode needle is withdrawn from the patient.

An ablation needle device can maintain flexibility of an injection needle even when the length of an electrode constituted at a distal end portion thereof is increased and can perform cooling with small nonuniformity in the electrode during ablation. The ablation needle device includes: a hollow needle that is composed of a proximal end portion that is insulation-coated and a distal end portion constituting an electrode; a hub that includes a liquid injection port and a discharge port; an electric connector; a thermocouple; and cooling liquid introducing pipes each of which extends in the inside of the hollow needle, each of which has a distal end positioned in the inside of the distal end portion of the hollow needle, and each of which ejects liquid injected from the injection port from a distal end opening thereof.

A surgical instrument includes an outer tube configured to be gripped by a user, and a needle slidably disposed within the outer tube. The needle includes a needle lumen, a distal needle tip configured to pierce tissue, and an electrode disposed at the distal needle tip. The needle lumen opens to the distal needle tip such that the distal needle tip is configured to deliver fluid from the needle lumen to tissue. The electrode is operable to deliver RF energy to tissue for ablating the tissue. The needle is translatable relative to the outer tube between a proximal retracted position in which the distal needle tip is housed coaxially within the outer tube, and a distal extended position in which the distal needle tip is exposed from the outer tube and configured to pierce tissue.

This invention relates to electrosurgical systems for coagulation and ablation of tissue, including in relation to tissue biopsy.

Surgical systems can include evacuation systems for evacuating smoke, fluid, and/or particulates from a surgical site. A surgical evacuation system can be intelligent and may include one or more sensors for detecting one or more properties of the surgical system, evacuation system, surgical procedure, surgical site, and/or patient tissue, for example.

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.

Disclosed herein is a medical RF apparatus using an RF pulse, comprising an RF generator, which generates a test pulse for detecting characteristics of tissue; a monitoring unit, which monitors the change in the information on the tissue state while the test pulse is transmitted to the tissue; and a measurement unit, which determines the tissue characteristics of a patient by comparing the values monitored in the monitoring unit with the reference data; and a method for controlling the same.
