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.

Disclosed are devices, systems, and methods for generating a graphical user interface for use during a microwave ablation procedure, an exemplary method comprising receiving microwave ablation procedure configuration settings, receiving ultrasound image data from the ultrasound sensor, receiving the EM tracking data from the EM tracking system, determining a trajectory of the ablation probe based on the EM tracking data, and generating a graphical user interface showing a position and orientation of the ablation probe and the trajectory in relation to a plane of the ultrasound image data.

A system for recording or recalling ablation information includes a workstation, and control circuitry. The workstation may include a display, a user input device, and a memory. The workstation may be configured to be in electrical communication with an ablation device. The control circuitry may be in electrical communication with the ablation device and the memory. The control circuitry may be configured to receive input associated with an ablation procedure performed by the ablation device, and associate the input with an anatomical structure of the patient.

An antenna system comprises a transmission member and an antenna at a distal end of the transmission member. The antenna includes a first conductive arm, an insulator extending around the first conductive arm, and a second conductive arm wound around at least a first portion of the insulator to form a second conductive arm coil. A property of the insulator varies along an insulator longitudinal axis of the insulator. The insulator includes a set of formed patterns along at least a portion of the insulator longitudinal axis.

A surgical instrument includes a handle assembly, an elongated shaft, an end effector, and an evacuation port. The elongated shaft extends distally from the handle assembly and includes an outer wall. The end effector is coupled to a distal portion of the elongated shaft. The evacuation port is configured for fluid communication with a suction device. A portion of the evacuation port is disposed within the outer wall of the elongated shaft.

A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to treat tissue to create lesions without ablating the tissue. The system includes a first treatment device having a plurality of electrodes. The electrodes are maintained in axial alignment and fixed radial spacing in retracted and extended positions. The device includes a basket having a plurality of arms. The arms are maintained in a fixed radial spacing in the collapsed position of the basket.

An electrosurgical apparatus and method for performing thermal treatment in the gastrointestinal tract, e.g. to ablate duodenal mucosal tissue. The apparatus comprises an instrument having a flexible cable and an applicator suitable for use with a gastroscope, which can be deployed within a patient to delivery energy in a targeted or otherwise controllable manner. The applicator can deliver microwave energy by radiation. The direct and depth-limited nature of microwave energy can be make it more effective than treatments that rely on thermal conduction. The applicator may include a radially extendable portion arranged to move an microwave energy delivery structure into contact with duodenal mucosal tissue at the treatment region. The applicator may comprise any of a balloon, bipolar radiator, movable paddle, and rotatable roller element.

Provided herein are systems, devices and methods for the treatment of fungus. In particular, provided herein are systems, devices and methods employing energy to nail and tissue structures to treat fungal infection.

An ablation probe tip 100 having a shaft 102 with an insertion end 104 and an annular aperture 120 near the insertion end 104. A center of ablation 124 is located within the shaft 102 and surrounded by the annular aperture shaft 102. The ablation probe tip 100 may be part of an ablation probe system 50 that includes an ablation source 60 that provides ablation means 62 to the ablation probe tip 100. The center of ablation 124 is a focal region from which the ablation means 62 radiates through the annular aperture 120 to form an ablation zone 150, 160, 170. The system 50 has at least one intra-operative control selected from the group of: ablation zone positioning control, ablation zone shaping control, ablation center control, ablation zone temperature control, guided ablation volume/diameter control, and power loading control.

Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.
