An apparatus comprises a first jaw, a second jaw, a first handle, and a second handle. The second jaw is pivotally coupled with the first jaw. The first jaw and the second jaw are configured to grasp tissue. The jaws provide offset electrode surfaces that are operable to deliver bipolar RF energy to tissue grasped between the jaws. The apparatus is further operable to sever tissue. A lockout feature selectively prevents tissue severing, based on an energization state of the jaws.

A catheter has a cooling distal section for freezing tissue to sub-zero temperatures with one or more miniature reverse thermoelectric or Peltier elements, also referred to herein as micro-Peltier cooling (MPC) units or electrodes. The MPC units may be on outer surface of an inflatable or balloon member or a tip electrode shell wall that has a fluid-containing interior cavity acting as a heat sink. Each MPC unit has a hot junction and a cold junction whose temperatures are regulated by the heat sink, and a voltage/current applied to the MPC units. A temperature differential of about 70 degrees Celsius may be achieved between the hot and cold junctions for extreme cooling, especially where the MPC units include semiconductor materials with high Peltier co-efficients. An outer coating of thermally-conductive but electrically-insulative material seals the MPC units to prevent unintended current paths through the MPC units.

An exemplary embodiments of the present disclosure are directed to providing a skin care apparatus using plasma and near-infrared ray designed to provide effects of improving skin and lifting by irradiating plasma and near-infrared ray generated through dual electric generation on skin contacted by a spherical form. Further, the exemplary embodiments of the present disclosures are directed to providing a skin care apparatus using plasma and near-infrared ray that prevents skin contact or dual irradiation, which were used to happen in the conventional side contact structure, with the method of irradiating plasma and near-infrared ray by using dielectric barrier discharge for each of the plasma discharge groove and near-infrared irradiation groove that are different from the conventional contact structure, through a spot contact spherical body structure.

Systems and methods for delivering energy to passageways in a patient, such as airways in the lung of a patient for treating asthma. One embodiment of a method for delivering energy to a passageway comprises positioning an access device in a lung airway of a patient and advancing an elongated body of a treatment device along the access device until an energy delivery unit at a distal portion of the elongated body projects from the access device. The method can further include expanding the energy delivery unit such that energy delivery elements contact a sidewall of the airway and activating an energy supply coupled to the treatment device such that energy is delivered to the sidewall of the airway. A single person physically operates both the access device and the treatment device while expanding the energy delivery unit and activating the energy supply.

A method and system for tattoo removal from a subject by exposing tattoo ink particles trapped within the dermis to a cold plasma is described herein. The tattoo removal method and system can be used to remove the tattoo from the skin of the subject being treated. In addition, the method and system described allows for the extraction of the tattoo ink particles, which may have toxic properties, from the subject's body.

Tumor treating fields (TTFields) can be delivered by implanting a plurality of sets of implantable electrode elements within a person's body. Temperature sensors positioned to measure the temperature at the electrode elements are also implanted, along with a circuit that collects temperature measurements from the temperature sensors. In some embodiments, an AC voltage generator configured to apply an AC voltage across the plurality of sets of electrode elements is also implanted within the person's body.

An expansion body that radially expands and contracts; an elongated shaft portion having a distal portion including a proximal end fixing portion to which a proximal end of the expansion body is fixed; a plurality of electrode portions provided along the expansion body are included, and the expansion body includes a recess portion recessed radially inward when the expansion body expands and defining a reception space that receives a biological tissue. The recess portion includes a bottom portion positioned at a radial innermost side, a proximal side upright portion extending radially outward from a proximal end of the bottom portion, and a distal side upright portion extending radially outward from a distal end of the bottom portion. One of two electrode portions that are circumferentially adjacent to each other is arranged at the proximal side upright portion, and the other is arranged at the distal side upright portion.

An unattended approach can increase the reproducibility and safety of the treatment as the chance of over/under treating of a certain area is significantly decreased. On the other hand, unattended treatment of uneven or rugged areas can be challenging in terms of maintaining proper distance or contact with the treated tissue, mostly on areas which tend to differ from patient to patient (e.g. facial area). Delivering energy via a system of active elements embedded in a flexible pad adhesively attached to the skin offers a possible solution. The unattended approach may include delivering of multiple energies to enhance a visual appearance.

A system for modulating bladder function is disclosed. A system for evaluating the electrophysiological function of a bladder is disclosed. Methods for performing a controlled surgical procedure on a bladder are disclosed. A system for performing controlled surgical procedures in a minimally invasive manner is disclosed. An implantable device for monitoring and/or performing a neuromodulation procedure on a bladder is disclosed.

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter shaft. An expandable member may be coupled to the catheter shaft. The expandable member may be capable of shifting between a folded configuration and an expanded configuration. A plurality of flexible elements may be attached to the expandable member, with a plurality of electrode assemblies disposed on the flexible elements. The flexible elements may have a grooved substrate.
