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.

Automated image-guided tissue resection and treatment

A surgical treatment apparatus comprises an elongate support, an elongate tube, and a movable endoscope having a stiff distal portion, in which the stiff distal portion of the endoscope is configured to move one or more components of the apparatus when the support remains substantially fixed. The support may comprise a plurality of spaced apart aspiration openings near the distal end in order to facilitate alignment with the treatment site. In many embodiments, an image guided treatment apparatus is configured for use with an imaging device. In many embodiments, a target resection profile is provided. The target resection profile and one or more tissue structures are displayed on an image, and the target resection profile displayed on the image is adjusted with user input.

Physician controlled tissue resection integrated with treatment mapping of target organ images

A fluid stream is directed toward tissue to generate a plurality of shedding clouds. The fluid stream can be scanned such that the plurality of shedding clouds arrive a different overlapping locations. Each of the plurality of shedding clouds can remove a portion of the tissue. In many embodiments, an apparatus to ablate tissue comprises a source of pressurized fluid, and a nozzle coupled to the source of pressurized fluid to release a fluid stream, in which the fluid stream generates a plurality of shedding clouds.

Tissue resection and treatment with shedding pulses

A delivery device for an annular implant that includes a balloon expansion mechanism and an annular implant having an adjustable dimension. The balloon expansion mechanism includes an inflation tube attached to a non-occluding balloon collar which is supported by trusses radially extending from a trocar. The annular implant further includes a flexible ring core, contiguous coiled spacers, and anchoring blocks. The flexible ring core is adjusted via a cinching mechanism. The anchoring blocks are spaced along the ring core by the contiguous coiled spacers, which keeps the distance between each pair of anchoring blocks equidistant as the ring core diameter is manipulated by the device user. The annular implant can also include gunbarrel elements housed in the trocar. Each gunbarrel element contains a gunbarrel pusher which drives an attachment element into the annular implant and annular tissue.
