A surgical device integrating a suction mechanism with a coagulation mechanism is provided for improving lesion creation capabilities. The device comprises an elongate member having an insulative covering attached about means for coagulating soft tissue. Openings through the covering expose regions of the coagulation-causing elements and are coupled to lumens in the elongate member which are routed to a vacuum source. A fluid source to passively transport fluid along the contacted soft tissue surface may be provided in order to push the maximum temperature deeper into tissue.

A portable electrosurgical device (ESD) has a housing, a probe connected to the housing and a heating element connected to the probe for destroying human tissue. The heating element is detachable from the probe and/or the probe with heating element can be detachable from the housing. The user can set a drive signal's electrical characteristics, such as operating frequency, duty cycle, peak voltage and the like for a customized drive signal formed in the ESD based on the heating element used. Memory storage allows for storage of inputted data from a keyboard, downloaded reference documents and information off the Internet from an Ethernet connector that can be displayed for reference on a screen of the ESD. Another even more compact ESD is an integral one-piece portable device having a type of pistol hand-held grip, dis-connectable probe, and a rechargeable, removable battery in the handle provides approximately 30, one-minute treatments on a single battery charge.

The present disclosure is directed to a medical device. Systems and methods are provided for utilizing a laser to break a kidney stones into smaller fragments and/or dust, and removing particles, stone fragments and/or stone dust from a patient. The medical device may include a tube having a distal end and a proximal end, a first lumen extending from the proximal end to the distal end of the tube and in fluid communication with the distal end and a plurality of side ports located at a distal portion of the tube, and a second lumen extending from the proximal end to the distal end of the tube.

A method including transmitting, by a mobile device, a first encrypted gadget token over a wireless link to an Information Handling System (IHS). The method further including transmitting, by the IHS, an encrypted system token based on the first decrypted gadget token over the wireless link to the mobile device, transmitting, by the mobile device, a second encrypted gadget token based on the decrypted system token over the wireless link to the IHS, authenticating, by the IHS, the second decrypted gadget token, and unlocking the IHS based on the second authenticated gadget token.

A device for providing a cryotherapy ablation treatment includes a piping assembly and a snow horn adapted to create a spray of snow from a pressurized source of a low-temperature liquid, a tubular applicator for collecting a mass of snow at a prescribed density that is sufficient to allow the mass to serve as the needed, low temperature, thermal reservoir for the device after the applicator's distal end has been disconnected from the snow horn end so that it can to be used during the treatment process, and an applicator tip adapted to allow it to connect to the applicator's distal end and be used to treat those specific locations which are to receive this treatment.

A system comprises a teleoperated manipulator, a manually operated surgical instrument coupled to the teleoperated manipulator, a teleoperated surgical instrument coupled to the teleoperated manipulator, and a shape sensor comprising a first portion and a second portion. The first portion of the shape sensor is coupled to a proximal end of a cannula, and the second portion of the shape sensor is coupled to the manually operated surgical instrument. The shape sensor is configured to provide a sensor input to a controller, and the sensor input comprises information representing an insertion depth of the manually operated surgical instrument into the cannula.

A system, ablation probe, and method is provided for treating tissue, e.g., tissue having tumors. The treatment system is configured to automatically deliver infusaid to tissue when needed and comprises an ablation probe having an ablative element and at least one perfusion exit port. The system further comprises an ablation source operably coupled to the ablative element, and a pump assembly operably coupled to the perfusion exit pots). The pump assembly is configured for pumping infusaid out through the perfusion exit port(s), preferably during the ablation process. The system further comprises a feedback device configured for controlling the amount of infusaid displaced by the pump assembly based on a sensed tissue parameter, e.g., tissue temperature or tissue impedance.

A catheter for use with a suction source for removing excess fluid from a tissue treatment site has a catheter body, a distal section and a fluid evacuation path, where the distal section includes a multi-lumened member and at least one evacuation port, and the fluid evacuation path extends through a lumen in the multi-lumened member to provide suction communication between the suction source and the at least one evacuation port. The fluid evacuation path may also be configured for two-way flow, including distally and proximally along the catheter.

A system and method for performing a radiofrequency (RF) ablation procedure with a cooled RF probe includes measuring one or more local perfusion characteristics at an ablation site within a patient. The method also includes determining a heat transfer due to local perfusion at the ablation site based on the one or more local perfusion characteristics. Further, the method includes determining an operating threshold for the cooled RF probe based, at least in part, on the heat transfer. Moreover, the method includes controlling the cooled RF probe based on the operating threshold to create a lesion at the ablation site within the patient.

An ultrasonic tip for use with a surgical handpiece to produce both longitudinal and torsional motion. The ultrasonic tip comprises a shaft having a longitudinal axis extending between proximal and distal ends having respective first and second diameters with the first diameter greater than the second diameter. The ultrasonic tip also comprises a cutting feature coupled to the distal end of the shaft. The shaft defines an aspiration lumen that extends along the longitudinal axis of the shaft. A protrusion on the shaft is positioned between the distal end and the proximal end of the shaft. A portion of the protrusion having a third diameter, and the third diameter is less than the first diameter and the third diameter is greater than the second diameter. An aperture is defined by the protrusion and in fluid communication with the aspiration lumen, and the protrusion reinforces an area surrounding the aperture.
