An ablation device of a non-invasive radio-frequency ablation system includes a substrate having a first surface; a first electrode disposed on the first surface; a second electrode disposed on the first surface and adjacent to the first electrode; a moving unit electrically connected to the second electrode for moving the second electrode to regulate the distance between the second electrode and the first electrode; and a radio frequency generator connected to the ablation device for providing a radio frequency current to the first electrode and the second electrode. According to a method using the ablation device, the first and second electrodes are brought into contact with a third surface belonging to a subject in need of treatment, and the radio frequency current is applied to the electrodes to carry out a treatment procedure. The treatment depth and area are adjusted by changing the relative distance between the electrodes.

A system to treat a patient comprises a user interface that allows a physician to view an image of tissue to be treated in order to develop a treatment plan to resect tissue with a predefined removal profile. The image may comprise a plurality of images, and the planned treatment is shown on the images. The treatment probe may comprise an anchor, and the image shown on the screen may have a reference image marker shown on the screen corresponding to the anchor. The planned tissue removal profile can be displayed and scaled to the image of the target tissue of an organ such as the prostate, and the physician can adjust the treatment profile based on the scaled images to provide a treatment profile in three dimensions. The images shown on the display may comprise segmented images of the patient with treatment plan overlaid on the images.

A surface of an object comprises a material having a low surface energy. A first cover comprising a material having a higher surface energy than the surface of the object may cover and be affixed to the surface. A second cover may be adhered to and/or secured by the first cover so that the second cover is fixedly coupled to the surface of the object.

A system for controlled neuromodulation procedures is disclosed. A system for controlled micro ablation procedures is disclosed. Systems and methods for imaging, monitoring, stimulating, and/or ablating neurological structures coupled to one or more organs of the lower urinary tract (LUT) are disclosed. Such processes may be used to alter the hormonal secretions from one or more organs, to modulate the growth of an organ, alter the growth rate or rate of perineural invasion of a tumor, or the like. In particular such processes may be used to slow, halt and/or reverse the growth of a prostate gland or a prostate tumor.

An anoscope comprises a graspable portion, arranged for being grasped by an operator, and a body, arranged for being inserted into the terminal tract of the rectum of a patient. A cavity and at least one operating window are made in the body of the anoscope. The anoscope further comprises a housing and a seat, which are comprised in the cavity of the body. The housing is arranged for containing at least one surgical instrument suitable for treating hemorrhoids and the seat is arranged for containing at least one lighting device. A method for treating a hemorrhoid in a patient comprises the following steps: a) Inserting an anoscope into the terminal tract of the rectum of the patient through the anal opening; b) Positioning the body of the anoscope in such a way that an operating window or opening of the anoscope is near a zone of rectal mucosa to be treated, positioned near the hemorrhoids; c) Positioning a surgical instrument suitable for treating hemorrhoids inside the body of the anoscope so as to reach the operating window or opening and, through the operating window or opening, reaching the zone of rectal mucosa to be treated; d) Producing a localized heat in the submucosa of the zone of rectal mucosa to be treated through the surgical instrument, such localized heat being a heat that is limited to the zone of rectal mucosa to be treated; e) Inducing a volume reduction of the hemorrhoid as a result of the localized heat produced.

A method of performing a surgical procedure includes generating an infrared image of tissue using a thermographic camera, analyzing the infrared images to determine blood flow characteristics of the tissue, and resecting a portion of the tissue determined to have abnormal blood flow characteristics.

Ablation catheters and systems include coaxial catheter shafts with an inner lumen for delivering an ablative agent and an outer lumen for circulation of a cooling element about the catheter. Induction heating is used to heat a chamber and vaporize a fluid within by wrapping a coil about a ferromagnetic chamber and providing an alternating current to the coil. A magnetic field is created in the area surrounding the chamber which induces electric current flow in the chamber, heating the chamber and vaporizing the fluid inside. Positioning elements help maintain the device in the proper position with respect to the target tissue and also prevent the passage of ablative agent to normal tissues.
