A minimally invasive cosmetic procedure for de-bulking fat includes steps of: (a) injecting platelet rich plasma (PRP) into a subject area; followed by (b) heating fat cells in the subject area using radiofrequency; followed by (c) aspirating fat cells in the subject area using liposuction; followed by (d) injecting platelet rich plasma (PRP) into the subject area again. The PRP injecting step (a) may be performed two to seven weeks prior to the heating and liposuction steps (b) and (c); and the PRP injecting step (d) may be performed several days to four weeks after the heating and liposuction steps (b) and (c).

A medical device for treating a vein, including component parts thereof, wherein the device comprises a vein stretching member; a vein stretching member for use with the device; a kit of parts including the device and one or more vein stretching member and a method for treating a vein including use of the device.

The invention relates to a device (10) for generating a plasma jet (P) comprising a first conduit (11) inside a second conduit (12), a first electrode (17) and a second electrode (18) for generating an electric field in a feed gas flow (F) provided in a first flow channel (15) to generate a plasma jet (P), and adapted to provide a curtain gas flow (C) in the space between the first and second conduit (11,12), wherein the first electrode (17) is positioned radially outside of the first flow channel (15), and wherein the radial distance of the second electrode (18) from a longitudinal axis (I) is larger than the radial distance of the first electrode (17) from said longitudinal axis (1). The invention further relates to an endoscope comprising a device (10), a method for generating a plasma jet (P), a method and a use of the device (10) for manipulating a cavity.

An in vivo potential measurement device includes an insulating member and an amplifier. The insulating member has an electrode. The insulating member is inserted into an organ of a living body such that an outer peripheral face of the insulating member contacts with an inner wall face of the organ at a contact site. The electrode senses electric potential at the contact site. The amplifier amplifies the electric potential to obtain output voltage. The amplifier has input capacitance Cin and input resistance Rin that satisfy Cin/Ce>0.1 and 1/(2πfCeRin)>0.1, where Ce represents capacitance of the insulating member at the contact site, and f represents frequency of the electric potential at the contact site on the inner wall face. A contact state between the outer peripheral face and the inner wall face is evaluated using the output voltage.

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 vapor delivery system and method is provided that is adapted for treating prostate tissue. The vapor delivery system includes a vapor delivery needle configured to deliver condensable vapor energy to tissue. In one method, the vapor delivery system is advanced transurethrally into the patient to access the prostate tissue. The vapor delivery system includes a generator unit and an inductive heating system to produce a high quality vapor for delivery to tissue. Methods of use are also provided.

A vapor delivery device includes an induction coil system. The induction coil system can include a coiled fluid tube, a coiled wire, a capsule between the coiled fluid tube and the wire, and a cooling fluid supply configured to force a cooling fluid through the capsule across the coiled wire. The induction coil system can include a closed loop ferrite core, a wire coiled around a first portion of the ferrite core, and a fluid tube coiled around a second portion of the ferrite core. A wire coil can be contained in a cartridge system removably coupleable to a disposable vapor delivery device. The system can include a fluid flow controller and induction power regulation to maintain a specific operating pressure range for vapor within a uterus or other bodily cavity, tract, or duct.

An electrosurgical apparatus is provided including a housing, a flexible shaft, and a distal tip. The housing may further be coupled to an electrosurgical generator and gas supply. The distal tip of the electrosurgical apparatus may be grasped by a grasping tool, such that the orientation and position of the distal tip relative to the housing may be manipulated to achieve a plurality of positions. The electrosurgical apparatus provides electrosurgical energy and inert gas to an electrode within the distal tip of the electrosurgical apparatus to generate a plasma beam. In one aspect, the electrode is a retractable blade such that the electrosurgical apparatus can be used for mechanical and electrosurgical cutting during surgery when the electrode is in an extended position and for cold plasma applications during surgery when the electrode is in a retracted position.

It is possible to highly precisely determine a surface temperature of a balloon. A balloon catheter includes: a balloon; an outer cylinder shaft connected to a proximal end of the balloon; an inner cylinder shaft passing through the outer cylinder shaft to extend into the balloon to be connected to a distal end of the balloon; and a heating component disposed in the balloon for heating a liquid in the balloon. A liquid delivery path in communication with the balloon is formed between the outer cylinder shaft and the inner cylinder shaft. A temperature sensor is disposed in the liquid delivery path.
