A variable length interstitial probe apparatus includes: a probe for effecting thermal therapy and/or cryotherapy to a tissue; a flexible umbilical sheath permanently affixed to the probe, including at least one interface for supplying energy, cooling fluid, cooling gas, heating fluid, and/or heating gas to the probe; and an adjustable depth stop configured to slide along a length of a shaft region of the probe, and lock to the shaft region at a selected position. The adjustable depth stop is configured to engage a probe driver and/or a skull mount apparatus to stabilize positioning of the probe and to control a depth of entry of the probe into a patient. The probe may be configured to effect temperature modulation therapy, where processing circuitry activates a modulation pattern of thermal therapy emission and cryogenic therapy emission for applying a thermal dose to the tissue.

An interactive control unit is disclosed. The interactive control unit includes an interactive touchscreen display, an interface configured to couple the control unit to a surgical hub, a processor, and a memory coupled to the processor. The memory stores instructions executable by the processor to receive input commands from the interactive touchscreen display located inside a sterile field and transmit the input commands to the surgical hub to control devices coupled to the surgical hub located outside the sterile field.

Transducer-based systems and methods may be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Transducer activation characteristics, such as initiation time, activation duration, activation sequence, and energy delivery characteristics, can vary based on numerous factors. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers. Activation requests for a set of transducers can be denied if it is determined that a transducer in the set of transducers is unacceptable for activation.

An electrosurgical device is adapted for use through a port and within a body cavity. The device includes a gas supply supplying gas to a distal tip and a valve to regular such supply, and an electric supply for supplying electricity to the distal tip. A pressure relief system is provided to regulate an outflow of gas from within the body cavity to prevent exceeding a predetermined pressure. The inflow of the gas through the valve and outflow of gas through the pressure relief system may occur simultaneously.

Disclosed herein are high efficiency surgical devices and methods of using same using radio frequency (RF) electrical power and/or electrically heated filaments to destroy tumors, form lesions, denaturize, desiccate, coagulate and ablate soft tissues, as well as to drill, cut, resect and vaporize soft tissues. According to the principles of this invention, the electrosurgical instruments can be used with externally supplied conductive or non-conductive liquids, as well as without externally supplied liquids, a mode of operation often referred to as “dry field” environment.

The current invention concerns systems, devices and methods for the ablation of a ablation of the wall of one or more pulmonary veins (PV) from the inside, preferably transmural ablation and preferably at the level of the antrum. Hereby, one or more implant devices can be implanted in the vessels and can subsequently be heated by external energy-providing means.

A system for treatment target tissue comprises an ablation device and an energy delivery unit. The ablation device comprises an elongate tube with an expandable treatment element. The system delivers a thermal dose of energy to treat the target tissue. Methods of treating target tissue are also provided.

The current invention concerns systems, devices and methods for the ablation of a vessel's wall from the inside, more specifically to implant devices and to the ablation of the wall of one or more renal arteries from the inside, preferably transmural ablation. Hereby, one or more implant devices can be implanted in the vessels and can subsequently be heated by external energy-providing means.

Provided is a catheter including a shaft having a distal end and a loop disposed near the distal end and configured to curl around a tissue and receive, via the shaft, energy to denervate at least a portion of the tissue.

An electrosurgical system includes an instrument with an end effector (4) including a pair of opposing first and second jaw members (5 & 6), movable between open and closed positions. First and second electrodes (9, 17) are located on the first and second jaw members, while a third electrode (10) is also located on the first jaw member (6). The system includes first and second connections (19, 20) by which the electrodes can be connected to the output of an electrosurgical generator. The first electrode (9) is connected to the first connection (19), the second electrode (17) is connected to the second connection (20), and the third electrode (10) is connected to the first connection (19) via a capacitor (24). The third electrode (10) is more prominent than the first electrode (9) such that as the jaw members are moved to their closed position, the third electrode (10) contacts the second electrode (17) before the first electrode (9) contacts the second electrode (17).
