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 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

One embodiment of an optical device comprises a fiber cap, an optical fiber and a bond between the fiber cap and the optical fiber. The fiber cap comprises a cap body having a closed distal end and a bore having a tapered section. The optical fiber comprises cladding surrounding a core. A distal end of the cladding comprises a tapered section that engages the tapered section of the bore.

Optical device

A medical laser system and related methods of monitoring optical fibers to determine if an optical fiber cap on the optical fiber is in imminent danger of failure. The laser system includes a photodetector for converting returned light from the optical fiber cap to an electronic signal for comparison to a trigger threshold value known to be indicative imminent fiber cap failure. The returned light can be the main laser treatment wavelength, an auxiliary wavelength such as an aiming beam or infrared wavelengths generated by a temperature of the optical fiber cap. In the event the electronic signal reaches the trigger threshold value, the laser system can be temporarily shut-off or the power output can be reduced.

Fiber damage detection and protection device

A hair removal device () includes a cooling surface () which is used to contact the skin () prior to exposure to hair tissue-damaging laser light () passing from a radiation source () through a recessed window (). The window is laterally offset from the cooling surface and is spaced apart from the cooling surface in a direction away from the patient's skin to create a gap between the window and the skin. The window preferably includes both an inner window () and an outer, user-replaceable window (). The laser-pulse duration is preferably selected according to the general diameter of the hair.

Tissue treatment system

A radiation delivery module () includes a body () supportable on a patient's skin and defines a skin surface plane generally aligned with the patient's skin surface (). A radiation source () is mounted to the body and produces a beam () of tissue-damaging radiation directed transverse to and at the skin surface plane. The radiation beam creates a radiation spot () having a length () and a width () at the skin surface plane, the length being at least about 5 to 10 times the width. A number of scanned diode laser radiation sub-sources () each directing a radiation beam component () at the radiation spot may be used. The radiation source may include a rod lens as a focusing optical element. The radiation delivery module may also include a radiation source translator () so that the radiation spot moves in a direction generally perpendicular to the length of the radiation spot.
