The disclosure relates to a device and a method for the treatment of diseases of the skin, glands, mucousae, connective tissue, nerves and/or horny tissue. The device is adapted for the treatment of diseases of the skin, glands, mucousae, connective tissue, nerves and/or horny tissue and has at least one applicator, which applicator is arranged outside the device housing; at least one radio wave module, which radio wave module is adapted to generate an adjustable electromagnetic radiation with a variable frequency or with at least one constant frequency with an adjustable variable or at least one adjustable constant intensity.

Ferritin or iron-based image enhancement agents identify target tissue for treatment or ablation and are heated by microwave absorption. Microwave heat substrates enhance microwave hyperthermal ablation treatment, and may be percutaneously delivered and imaged by x-ray CT during placement of the microwave treatment antenna, allowing more precise positioning and more complete ablation of a tumor site. One method of treating a target tissue uses image-guided delivery of a heat substrate with a reverse-phase change polymer, and may apply energy to fix a mass of the material in the tissue. The fixed polymer may increase hyperthermia, form a thermal boundary, or blockade a vessel or passage so as to reduce or prevent undesired conductive cooling by contiguous tissue, or may deliver a localized treatment drug at the site, upon heating or as it degrades over time.

A flexible microwave ablation antenna and a microwave ablation needle including the same are disclosed. The flexible microwave ablation antenna including: a radiator for transmitting microwave for ablation; a coaxial cable for propagating the microwave for ablation generated by a microwave generator to the radiator; wherein the flexible microwave ablation antenna is bendable. Preferably, an annular composite structure is disposed around a periphery of the coaxial cable to suppress the electromagnetic wave from propagating along the coaxial cable in a reverse direction. The annular composite structure includes an annular non-metallic layer and an annular metallic layer surrounding the annular non-metallic layer. The annular metallic layer is electrically insulated from the coaxial cable.

A portable test apparatus for testing an RF/microwave treatment system, the portable test apparatus comprising: a connector configured for connection to a generator or amplifier of the treatment system and/or to a distal end of a reusable transmission cable of the treatment system; a measurement device configured for measuring RF/microwave energy received through the connector; and a test controller configured to: run at least one test of a set of tests for testing the treatment system, at least some of the set of tests comprising using the measurement device to measure RF/microwave energy supplied by a generator or amplifier of the treatment system to a proximal end of the reusable transmission cable and transmitted through the reusable transmission cable to the connector; and analyse and/or record and/or output results of the set of tests.

Embodiments of the present disclosure pertain to transmission dielectric probes with at least one channel that extends across the probe. The channel includes a first opening on a first side of the transmission dielectric probe, and a second opening on a second side of the transmission dielectric probe. The first opening and the second opening are on opposite ends of the transmission dielectric probe, and the second opening is associated with an outer surface of the transmission dielectric probe. Additionally, the first opening and the second opening have different diameters, different geometries, or combinations thereof. Further embodiments pertain to methods of operating the transmission dielectric probes by placing the outer surface of the transmission dielectric probe on a surface of an object, transmitting a signal from a first channel through the surface and into the object, and receiving the transmitted signal back through a second channel.

A system for neuromodulation includes a split-ring resonator (SRR) comprising a resonance circuit, the SRR being implantable in a cranial target site and a source of microwave signals, wherein the microwave signals are deliverable wirelessly to couple with the SRR to produce a localized electrical field, wherein the localized electrical field inhibits one or more neurons at the cranial target site with submillimeter spatial precision.

A surgical probe includes a connection hub, an antenna assembly, and an outer jacket. The antenna assembly is coupled to the connection hub, extends distally from the connection hub, and includes a radiating portion coupled thereto at the distal end thereof. The radiating portion is configured to deliver energy to tissue to treat tissue. The outer jacket is coupled to the connection hub, extends distally therefrom, and is disposed about the radiating portion. The outer jacket includes a distal end member configured to be spaced-apart from the radiating portion a target axial distance. One or more of the couplings between the antenna assembly and the connection hub, the radiating portion and the antenna assembly, and the outer jacket and the connection hub defines a flexible configuration permitting axial movement therebetween to maintain the target axial distance between the radiating portion and the distal end member.

The present invention relates to comprehensive systems, devices and methods for delivering energy to tissue for a wide variety of applications, including medical procedures (e.g., tissue ablation, resection, cautery, vascular thrombosis, treatment of cardiac arrhythmias and dysrhythmias, electrosurgery, tissue harvest, etc.). In certain embodiments, systems, devices, and methods are provided for delivering energy to difficult to access tissue regions (e.g. peripheral lung tissues), and/or reducing the amount of undesired heat given off during energy delivery.

A forceps includes a drive assembly and an end effector assembly having first and second jaw members movable between a spaced-apart position, a first approximated position, and a second approximated position. The drive assembly includes a drive housing and a drive bar. The proximal end of the drive bar is coupled to the drive housing, while the distal end of the drive bar is coupled to at least one of the jaw members. The drive housing and the drive bar are selectively movable in conjunction with one another between a first position and a second position to move the jaw members between the spaced-apart position and the first approximated position. The drive assembly is selectively activatable to move the drive bar independent of the drive housing from the second position to a third position to move the jaw members from the first approximated position to the second approximated position.
