A device for providing a magnetic treatment by evoking muscle contraction by a time-varying magnetic field and providing a RF treatment by heating biological structure. The device may provide a pressure treatment. The device includes an applicator having an RF electrode and a magnetic field generating device. The device may also include a main unit, a human machine interface, and a control unit. The control unit adjusts a signal provided to the RF electrode and creates an RF circuit, and also adjusts the signal provided to the magnetic field generating device and creates a magnetic circuit electrically insulated from the RF circuit. The RF circuit may include a power source and a power amplifier, and the magnetic circuit may include an energy storage to supply the magnetic field generating device with electric current.

Electrosurgical lysing devices and related systems and methods. In some embodiments, the lysing device may comprise a lysing tip comprising at least one bead comprising an at least substantially electrically non-conductive surface and at least one lysing member defining at least one lysing segment extending within a recess defined, at least in part, by the at least one bead, wherein the at least one bead protrudes both distally and proximally relative to the at least one lysing member.

An ultrasound transducer includes a plurality of piezoelectric elements that are layered in the thickness direction and that generate a longitudinal vibration in the thickness direction. The plurality of piezoelectric elements are arranged so that the thicknesses thereof are sequentially larger from the antinode side of the longitudinal vibration towards the node side of the longitudinal vibration.

An electrosurgical instrument for delivering radiofrequency (RF) electromagnetic (EM) energy and microwave frequency EM energy from a coaxial feed cable through an instrument tip into tissue. The instrument tip comprises a dielectric body separating first and second conductive elements, which act as active and return electrodes to convey the RF EM radiation by conduction, and as an antenna to radiate the microwave EM radiation. The instrument also has a fluid feed incorporated into its tip, e.g. in an additional dielectric element mounted on the underside of the tip, for delivering fluid. The delivered fluid may be a gas plasma to assist treatment or a liquid to plump up a tissue region before treatment. The instrument may fit in an endoscope.

Medical devices and methods for treating and occluding a female patient's fallopian tubes to provide permanent birth control or sterilization.

A device and system for removing polyps is provided and includes a tubular member having proximal and distal ends, a snare portion operably extending from within the distal end of the tubular member, the snare portion including a cutting member for severing the sealed tissue. The polyp removal device may further include a handle portion operatively extending from within the proximal end of the tubular member. The handle portion may be configured for operable engagement by a user and the cutting member may extend between distal ends of the first and second electrodes.

A marking method includes: a step of irradiating, with first light (narrow band light) from an endoscope, an observation target site not suitable for spray of a coloring agent in a subject; a step of picking up an image of, through the endoscope, second light (reflected light of the narrow band light) generated at the observation target site through irradiation of the observation target site with the narrow band light; a step of displaying an image in which a site suspected to be a tumor is highlighted by generating the image based on the second light received through the endoscope; and a step of providing a tissue denatured portion around the site suspected to be a tumor by using an energy radiation device while the displayed image is observed.
