A system and method for providing relative positional information of a therapeutic or diagnostic device during the treatment of urinary tract diseases and conditions.

Flexible instruments and associated systems and methods are disclosed herein. In some embodiments, a flexible instrument comprises an elongate device having an inner conductor, an outer conductor surrounding the inner conductor, and a dielectric layer insulating the inner conductor from the outer conductor. The flexible instrument further includes a recess formed in the outer conductor. An insert is positioned within the recess and about the inner conductor.

A metallic tube arrangement includes an electrode region configured to expand radially and contract radially in response to increasing and decreasing a temperature at the electrode region, respectively. The electrode region is configured for intravascular deployment and delivery of high frequency energy to target tissue of a target vessel of the body. The electrode region is configured to expand radially to a diameter sufficient to contact an inner wall of the target vessel in response to a decrease in electrode region temperature and to contract radially to a diameter smaller than a diameter of the target vessel in response to an increase in electrode region temperature.

Systems, devices, and methods for delivering laser energy to a target in an endoscopic procedure are disclosed. An exemplary method comprises providing a first laser pulse train and a different second laser pulse train emitting from a distal end of an endoscope and incident on a target. The first laser pulse train has a first laser energy level, and the second laser pulse train has a second laser energy level higher than the first laser energy level. In an example, the first laser pulse train is used to form cracks on a surface of a calculi structure, and the second laser pulse train causes fragmentation of the calculi structure after the cracks are formed.

Modules, systems and methods for clearing substances from a living body are disclosed. A module may include an instructions receiver configured to receive wireless transmissions of instructions from a master controller located outside of the body when the module is inside the body; an energy receiver configured to receive wireless transmission of non-destructive energy from the master controller located outside of the body when the module is inside the body; an energy converter configured to convert the non-destructive energy received to destructive energy; and an energy emitter configured to emit the destructive energy.

A medical device may include an ablation device configured to deliver ablation energy to a treatment site. The medical device may further include a probe device configured to deliver excitation radiation to the treatment site. Further the medical device may include a radiation-receiving device configured to receive photoluminescence radiation emitted from the treatment site in response to the treatment site being illuminated by the excitation radiation and to generate a detection signal in response to the received photoluminescence radiation. Additionally, the excitation radiation may be different from the ablation energy.

A medical system for use in a lithotripsy procedure may include a processor configured to receive input from a first imaging device, wherein the first imaging device may be configured to send image data representative of an image captured in a lumen of a kidney, bladder, or ureter to the processor. The processor may be configured to display the image on a display device coupled to the processor, and analyze the image to sense the presence of an object within the image. If an object was sensed within the image, the processor may analyze the image to estimate a size of the object, and display the estimate on the display device.

A medical system may include an insertion device including a delivery shaft with at least one lumen, a tube coupled to an exterior of the delivery shaft, and an adaptor coupling a distal end of the delivery shaft to a distal end of the tube. One of the delivery shaft and the tube may be configured to receive an energy delivery device, and the other of the delivery shaft and the tube may be configured to be coupled to a suction source to apply suction.

The present invention relates to a method for operating a pulsed diode-pumped solid-state laser comprising: providing a pump light source for pumping a solid-state laser, said pump light source comprising at least one laser diode unit configured for emitting a series of light pulses for pumping the solid-state laser, modulating the series of light emission pulses of the at least one laser diode unit such that only the light pulses with a frequency close to or equal to a requested frequency setting of the solid-state laser are operated with a/the required pulse amplitude and/or a/the required pulse duration to trigger light emission of the solid-state laser, and such that any other light pulses of the at least one laser diode unit are operated to not trigger light emission of the solid-state laser.

A method for conducting intrabody surgery by means of a surgical device having a cutting arrangement actuated by a driveshaft and rotationally supported by the guide wire. A receiving cannel extends through the cutting arrangement and movably receives the guidewire. A plurality of sensors is provided within the cutting arrangement to emit signals capable of changing parameters depending on the composition of the occlusion, so as to allow the control unit to generate signals controlling operation of the cutting arrangement. The method includes the steps of detecting parameters within the intrabody area by the sensors to controlling operation of the cutting arrangement with the power and control unit.
