A portable, battery powered electrosurgical wave generator is usable in performing electrically driven medical procedures. The wave generator can be small and lightweight to enable a user to carry and use the wave generator in non-operating room type settings. The wave generator can include a control unit that generates output signals in each of a cutting mode, coagulation mode, and a bipolar mode. The control unit can use a single circuit structure to generate the output signals for the cutting, coagulation, and bipolar modes. The output signals can be generated solely from a voltage produced by an incorporated battery within the generator.

Embodiments of medical treatment including skin treatment using electrical energy, especially with the primary purpose for skin treatment for aesthetics are described generally herein. Other embodiments may be described and claimed.

An electrosurgical device includes a handpiece, an electrode tip extending from the handpiece, the electrode tip configured to deliver an RF signal, and a multivariate controller disposed on the handpiece. The multivariate controller is configured to activate the electrode tip and adjust a setting of the RF signal within a range of settings.

Various cartridge assemblies for surgical instruments are provided. Cartridge assemblies can include active sensors for applying stimuli to a tissue clamped by an end effector of the surgical instrument and a circuit configured to determine a tissue type of the tissue according to a change in the tissue parameter detected by the sensor resulting from a stimulus from the active element. Cartridge assemblies can also include physical features and/or stored data that identify the cartridge. Surgical instruments further can be configured to resolve conflicts when the physical features and/or stored data are not consistent with each other in their identification of the cartridge type.

A pulse application method includes: setting a wavelength of light within a range in which a temperature rise width of collagen fibers in living tissue when the light is applied to the living tissue is larger than a temperature rise width of water containing cells that are contained in the living tissue and that are present around the collagen fibers; and applying a pulse of light with the set wavelength to the living tissue to heat the living tissue.

Systems, devices, and methods for transvascular ablation of target tissue. The devices and methods may, in some examples, be used for splanchnic nerve ablation to increase splanchnic venous blood capacitance to treat at least one of heart failure and hypertension. For example, the devices disclosed herein may be advanced endovascularly to a target vessel in the region of a thoracic splanchnic nerve (TSN), such as a greater splanchnic nerve (GSN) or a TSN nerve root. Also disclosed are methods of treating heart failure, such as HFpEF, by endovascularly ablating a thoracic splanchnic nerve to increase venous capacitance and reduce pulmonary blood pressure.
