摘要： 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.

摘要： Methods and systems for modifying tissue use a pressurized fluid stream carrying coherent light energy. The methods and systems may be used for resecting and debulking soft and hard biological tissues. The coherent light is focused within a stream of fluid to deliver energy to the tissue to be treated.

摘要： An intravascular catheter for peri-vascular and/or peri-urethral tissue ablation includes multiple needles advanced through supported guide tubes which expand with open ends around a central axis to engage the interior surface of the wall of the renal artery or other vessel of a human body allowing the injection an ablative fluid for ablating tissue, and/or nerve fibers in the outer layer or deep to the outer layer of the vessel, or in prostatic tissue. The system also includes means to limit and/or adjust the depth of penetration of the ablative fluid into and beyond the tissue of the vessel wall. The preferred embodiment of the catheter includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open uniformly and maintain their position against the interior surface of the vessel wall as the sharpened injection needles are advanced to penetrate into the vessel wall.

A method can involve injection/infusion of the ablative fluid over an extended time period of at least 10 seconds or with two injections at two different penetration depths to reduce or eliminate patient pain during ablation.

摘要： An apparatus is configured to provide hemostasis with tissue removal in order to inhibit one or more of blood loss or tissue drainage. In many embodiments, a nozzle releases a liquid jet in a liquid medium in order to provide cavitation and a plurality of shedding pulses. The liquid jet, its cavitation and the plurality of shedding pulses can affect vascular tissue in order to promote clotting in order to inhibit bleeding. In many embodiments, vessels of the vascular tissue are affected at a distance from a region where cavitation of the water jet contacts the tissue. In many embodiments, the cavitation and plurality of shedding pules are related to a pulsatile shear wave propagating along the blood vessel that is related to clot promoting changes of the blood vessel.

摘要： A medical device includes a capacitive micromachined ultrasonic transducer (CMUT) array configured to emit ultrasound to target tissue, and at least one thermoelectric cooler mechanically coupled with the CMUT array and configured to cool non-target tissue heated by the ultrasound. The medical device may be implemented in a catheter together with a solid thermal conductor coupled to the thermoelectric cooler and extending along the catheter, to conduct heat away from the thermoelectric cooler. A catheter or catheter sleeve includes a tubular wall for insertion into a body channel, and at least one thermoelectric cooler coupled to the tubular wall for cooling the body channel wall. A catheter sleeve includes tubular casing for insertion into a body channel and capable of encasing a catheter, and at least one sensor coupled to the tubular casing for sensing one or more properties of the body channel wall, such as temperature and pressure.

摘要： Apparatus and methods are described for treatment of a urethra that is constricted due to benign prostatic hyperplasia (BPH). A positioning device is used to determine a location of the area of the urethra that is constricted and is to be treated. An execution device includes a dilation balloon, a cutter, an implant carrier, and an implant, the implant and the implant carrier both being disposed outside the outer surface of the dilation balloon. The urethra is dilated by expanding the dilation balloon, and a cut is formed in the inner surface of the urethra using the cutter. The implant is released into the cut within the inner surface of the urethra subsequent to the cutter forming the cut in the inner surface of the urethra, to thereby maintain the urethra in a dilated state. Other embodiments are also described.
