An endorectal coil (1) includes a tube (40), a spreader (44), and one or more electrically conductive elements (64). The tube (40) is configured for insertion into the rectum (42). The spreader (44) is configured to be positioned at a distal end of the tube (40) and mechanically spread to compress surrounding tissue after the tube (40) is inserted. The one or more electrically conductive elements (64) are tuned to receive magnetic resonance data disposed on at least one of the tube (40), the spreader (44), and adjacent the tube and spreader.

The invention is within the general field of electroporation. In particular, the invention is within the general field of endoscopic electroporation and relates to a bipolar electrode suitable for endoscopic use, i.e. an electrode assembly that can be inserted in a resectoscope and deployed so as to treat e.g. internal organs tumors, such as bladder, rectum or esophagus.

A surgical instrument includes a hollow member having a sidewall provided with a window and a closure member movably connected to the hollow member for alternately covering and uncovering the window. The hollow member has a first clamping surface along an edge of the window, while the closure member has a second clamping surface opposing the first clamping surface and disposable substantially adjacent thereto in a clamping or closure configuration of the instrument. The instrument additionally comprises a tissue occlusion component mounted to at least one of the hollow member and the closure member for acting on tissues gripped between the first clamping surface and the second clamping surface, to couple the tissues to each other.

This invention is directed to a medical device and a method of treating mammals, especially humans, to alleviate the symptoms, including pain, of several conditions and symptoms, including hemorrhoids, tissue inflammation and/or yeast infections, and open, draining wounds or incisions.

A device and method for treating female urinary incontinence and also for treating fecal incontinence are presented. A fractional RF grid array is used to heat target tissue to a temperature of about 40-45 C. for a specified period of time, thus stimulating fibroblasts to produce type 1 collagen preferably without producing significant amounts of type 3 collagen. The device includes a temperature sensor and a control circuit to maintain the desired temperature of the target tissue and avoid overheating. Target tissue includes tissue in and around the urethra, and in and around the anus including the perineum. The wand to which the RF grid array is mounted has visible gradations on it so that the user can treat one area at a time, then reliably move the grid array to the next adjacent area even though the grid array is hidden from view inside a portion of the body. The device can also be used for vaginoplasty.

The invention relates to a method for the treatment of haemorrhoids and the use of said method for embolization and/or ablation of the underlying vein(s) that cause(s) haemorrhoids.

A component for use in magnetic resonance image-guided laser ablation has: d) a one-piece cannula having at least one laser-transmitting fiber fixed thereto; e) the one-piece cannula comprising a composition having a proximal insertion end and a thermal energy-emitting tip; and f) fluid conducting channels fixed to the energy-emitting tip.

The fluid conducting channels have fluid-carrying dimensions sufficient to transport sufficient liquid at 15 C. through the channels to cool both tissue adjacent the channels and the tip during emission from a tissue ablating laser within the thermal energy emitting tip. The composition of the one-piece cannula is at least translucent/transparent to at least 50% of infrared radiation between 900-1200 nm emitted from within the cannula at the thermal energy-emitting tip. The composition of the one-piece cannula should have a melting temperature of at least 150 C.

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.
