For liver modeling from medical scan data, multiple modalities of imaging are used. By using multiple modalities of imaging in combination with generative modeling, a more comprehensive and informed assessment may be performed. The generative modeling may allow feedback of effects of proposed therapy on function of the liver. This feedback is used to update the liver function information based on the imaging. Based on the computerized modeling with information from various imaging modes, an output based on more comprehensive information and patient personalized modeling and feedback may be provided to assist the physician.

A bipolar ablation device for treatment of a stenosis within an implanted metallic stent may include an elongate shaft slidably disposable within an endoscope, the elongate shaft including at least one electrode configured to form a first pole of the bipolar ablation device, and an electrode lead slidably disposable within the endoscope. The electrode lead may be configured to electrically engage the implanted metallic stent to form a second pole of the bipolar ablation device. The elongate shaft may be positionable within a lumen of the implanted metallic stent.

A system for delivering a stent into a body lumen includes an inner tubular member configured to advance through an access site in a wall of a body lumen for delivering a stent into the body lumen and an electrode configured to create the access site in the wall of the body lumen. A tubular sleeve is disposed coaxially over the distal end portion of the inner tubular member and is configured to thermally insulate at least a portion of the inner tubular member.

A lithotripsy apparatus includes: a treatment laser beam source that emits a treatment laser beam that crushes a stone; a guide light source that emits guide light; a photodetector that detects return light that returns as a result of the emitted guide light being reflected at the stone; and a processor including hardware, the processor being configured to: measure a distance from the treatment laser beam source to the stone on the basis of the return light; determine a condition of a bubble occurring between the treatment laser beam source and the stone on the basis of the measured distance; and adjust a light quantity of the treatment laser beam on the basis of the determined condition of the bubble.

Systems, devices, and methods for determining a distance between a distal end of an endoscope and a target during an endoscopic procedure are disclosed. A surgical laser feedback control system comprises a feedback analyzer and a controller. The feedback analyzer can receive at least two reflected signals from a target in response to electromagnetic radiation directed at the target. The at least two reflected signals correspond to respective different distances between a distal end of a device of a surgical laser system and the target. The feedback analyzer can determine a distance between the distal end of the device of the surgical laser system and the target based on the at least two reflected signals. The controller can generate a control signal to the surgical laser system to perform a predetermined operation based on the determined distance.

Methods and systems for the controlled generation of bubbles in a medium having a liquid phase are generally provided. Laser pulses having a time-dependent pulse parameter controllable over their duration are generated. The medium is irradiated with the laser pulses with a radiant exposure sufficient to initiate microcavitation within the medium during each laser pulse. The time-dependent pulse parameter of each laser pulse is controlled according to a generally positive variation over the pulse duration such that the medium absorbs a greater quantity of energy from the laser pulse at an end of the pulse duration than at a beginning thereof. Such methods and systems may be used for various applications such as biology, medicine or material processing.
