The present disclosure is directed to a method of performing a photo-thermal dermatological procedure without use of an injectable anesthetic. The method includes applying a topical anesthetic to a treatment area of skin, measuring a surface temperature of the treatment area of skin, and passing a stream of cold air over the area of skin such that the surface temperature of the treatment area of skin is maintained between 0 degrees Celsius and 15 degrees Celsius for a duration of at least 30 seconds. The method further includes administering a photo-thermal energy dose to the area of skin after the duration.

A portable depilation instrument includes a shell, and a depilation mechanism and a heat dissipation mechanism inside the shell. The shell is provided with at least two outlets and one inlet, the shell introduces an external cooling medium from the inlet, the heat dissipation mechanism includes a heat conductive component, the depilation mechanism includes a refrigeration element and an emitter, the heat conductive component isolates the refrigeration element from the emitter in two mutually sealed channels, namely, a first channel and a second channel, the first channel and the second channel are respectively in communication with two outlets, and one of the outlets allows the first channel or the second channel to pass through inside of the entire shell from one end to the other end. Due to complete isolation and a push force, air can be discharged only from a respective corresponding outlet after a heat exchange.

A method for performing a medical procedure in an intestine of a patient is provided. The method comprises providing a system comprising: a catheter for insertion into the intestine, the catheter comprising: an elongate shaft comprising a distal portion; and a functional assembly positioned on the shaft distal portion and comprising at least one treatment element. The catheter is introduced into the patient, and target tissue is treated with the at least one treatment element. The target tissue comprises mucosal tissue of the small intestine, and the medical procedure can be configured to treat polycystic ovarian syndrome (PCOS).

A minimally invasive medical technique for treating lung tumors includes use of multiple ablation modalities in a single procedure. Condensable vapor ablation and electrosurgical ablation are applied to treat the surface of the tumor and to debulk inner regions of the tumor, respectively.

Dermatological systems and methods for providing a therapeutic laser treatment using a handpiece delivering one or more therapeutic laser pulses to a target skin area along a first optical path, and sensing the temperature of the target skin area based on infrared energy radiating from the target skin area along a second optical path generally counterdirectional to the first optical path, and sharing a common optical axis with the first optical path for at least a portion of the first and second optical paths. The handpiece may also provide contact cooling for a first skin area comprising the target skin area.

Electrosurgical devices and systems having one or more porous electrodes are provided. An electrosurgical apparatus is provided having a shaft, a handle, and at least one porous electrode. The shaft is coupled to the handle and the at least one porous electrode is disposed on a distal tip of the shaft. The at least one porous electrode conducts energy provided to the distal tip and enables fluid provided to the distal tip to pass through the porous structure of the at least one electrode, such that the electrosurgical energy and the fluid are simultaneously applied to patient tissue adjacent to the at least one porous electrode. In one aspect, the electrosurgical apparatus includes a switching means configured to enable a user to select which of at least a first fluid, e.g. saline, or a second fluid, e.g., helium, to be provided to the distal tip.

Skin treatment apparatus comprising an energy applicator structure configured to establish heating or ablation at a predetermined and controllable (i.e. selectable) depth below a surface of skin tissue with which it is in contact. The applicator structure may receive a cooling medium and microwave frequency electromagnetic energy, which provide a combined treatment effect that results in heating or ablation in a zone beneath the skin surface. The applicator may be a waveguide (e.g. waveguide horn antenna) with internal shielding configured to provide a substantially uniform heating effect. The applicator may include a thermal camera to monitor treatment.

Methods and systems for modulating intraosseous nerves (e.g., nerves within bone) are provided. For example, the methods and systems described herein may be used to modulate (e.g., denervate, ablate) basivertebral nerves within vertebrae. The modulation of the basivertebral nerves may facilitate treatment of chronic back pain. The modulation may be performed by a neuromodulation device (e.g., an energy delivery device).

The present disclosure relates to a surgical tool for cutting and hemostasis of biological tissues. The surgical tool includes a hollow blade comprising a cutting implement residing within a hollow cavity configured to provide high-pressure steam through an apical surface. The cutting implement can operate independently or in cooperation with the provided high-pressure steam. The surgical tool of the present disclosure applies a directionally-controlled, high-pressure steam flow to a tissue region of interest. A control unit provides temperature-controlled steam at a flow-rate determined in accordance with tissue type and intended procedure.

Dermatological systems and methods for providing a therapeutic laser treatment wherein the duration of a therapeutic laser pulse is based on one or more determinations of a surface temperature of the skin during the delivery of the pulse. Initiation of the therapeutic laser pulse may be based on sensed skin temperature during a cooling of the skin prior to initiation of the pulse.
