A method of treating tissue of a patient uses a device including a mother case, a belt, at least one treatment unit and at least two applicators. The treatment method may include attaching first and second applicators to the belt at a working distance to the patient's surface, and providing different treatment energy to the first applicator and the second applicator. A treatment pattern is created by the applicators providing the different treatment energies. The hardware pattern or positions of the applicators on the belt may be changed before and/or during the treatment. The hardware pattern may be based on selected treatment effect and body part.

A method for delivering cancer therapy may comprise introducing a tissue resection device to the tissue site, using the tissue resection device to create a core of tissue, removing at least a portion of the core of tissue from the body to create a tissue cavity, and performing therapeutic management of malignant tissue via the tissue cavity.

An endoscopic vessel harvester includes a vessel keeper with a capture frame capturing a target vessel within a tunnel that has been dissected along the target vessel. A cutter member cuts and cauterizes side branches while the target vessel is slidably captured in the vessel keeper. A fixed supporting rod and a movable side rod engage the frame. The movable side rod has an opened position to admit the target vessel and has a closed position to slidably capture the target vessel. One of the fixed support rod or the movable side rod is comprised of a hollow cylinder open at the distal end and at the proximal end, and wherein the distal end of the hollow cylinder fluidically communicates with the tunnel through the capture frame. A suction tube connects to the proximal end of the hollow cylinder, allowing pooled fluid around the capture frame to be removed.

A microwave ablation device (10) comprises a feed line (22), a microwave radiator and a device outer sheath (46) in which at least part of the feed line (22) is contained. The sheath (46) in use, allows an irrigation liquid to flow therethrough, wherein the feed line has a junction (38) with the radiator (22) has an outer conducting shield (28) terminating and insulated at the junction (38). The feed line (22) has a conductive core (32) that extends to the radiator (24). The conductive core forms a radiating element (34) electrically insulated from its surrounding environment. The radiator (24) is unbalanced.

Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the removal device. The removal device can have a core assembly that includes a hypotube coupled to a first electrical terminal and a pushwire coupled to a second electrical terminal, the pushwire extending through the hypotube lumen. An insulating layer separates the hypotube and the pushwire, and an interventional element is coupled to a distal end of the pushwire. The interventional element can be disposed adjacent to a thrombus. An electrical signal is delivered to the interventional element to promote adhesion of the thrombus to the interventional element. The electrical signal can optionally be a periodic waveform, and the total energy delivered can be between 0.75-24,000 mJ and the peak current delivered via the electrical signal can be between 0.5-5 mA.

The invention relates to a catheter ablation device for delivery of energy to a selected region of tissue, the device having an antenna portion including a radiating antenna electrically connectable via an electrical feedline to a source of energy, the antenna configured to generate an electromagnetic field able to ablate tissue in said selected region of tissue, the device including a thermocouple having a hot junction formed by electrical connection between a thermocouple conductor and a conducting part of the electrical feedline. This avoids the need for a dedicated thermocouple conductor pair, as the second conductor of the thermocouple is provided by the feedline used to supply the ablation energy to the device antenna. The thermocouple conductor may be a pull wire, such that its manipulation from a proximal portion of the catheter results in selective manipulation of the catheter at said antenna portion, the hot junction electrical connection providing a point of mechanical connection between the pull wire and the electrical feedline to enable the manipulation.
