An intracorporeal pressure shock wave includes an expandable pressure shock wave reflector at the distal end of an intracorporeal catheter to direct shock waves from a shock wave generator within a human or animal blood vessel or body lumen.

A method includes transmitting a focused ultrasound wave into a medium to form (i) an ultrasound intensity well within the medium that exhibits a first range of acoustic pressure and (ii) a surrounding region of the medium that surrounds the ultrasound intensity well and exhibits a second range of acoustic pressure that exceeds the first range of acoustic pressure. The method further includes confining an object within the ultrasound intensity well. Additionally, an acoustic lens is configured to be acoustically coupled to an acoustic transducer. The acoustic lens has a varying longitudinal thickness that increases proportionally with respect to increasing azimuth angle of the acoustic lens. Another acoustic lens is configured to be acoustically coupled to an acoustic that increases proportionally with respect to increasing azimuth angle of the segment.

A device for removing a urinary tract stone from a ureter may include an outer shaft, an inner shaft extending coaxially within the outer shaft, a self-expanding wire basket attached to a basket shaft extending coaxially within the inner shaft, an inflatable balloon and a handle. The balloon main include a rounded distal tip. The handle may include an inversion slider coupled to the inner shaft and configured to actuate the inner shaft, thereby inverting the distal tip of the inflatable balloon to form a pocket adapted to receive a urinary tract stone. The handle may also include a basket slider coupled to the basket shaft and configured to actuate the basket shaft to move the wire basket in and out of the inner shaft.

A surgical laser system comprises a laser source configured to generate laser energy; a laser fiber optically coupled to the laser source and configured to discharge the laser energy generated by the laser source; a rocker arm configured to control an orientation of the discharged laser energy; and a controller configured to control a movement of the rocker arm in response to feedback of the discharged laser energy or to pre-defined settings of the laser source.

Provided herein are methods for treating nephrolithiasis and protecting the urothelium and inner lining of the kidney from thermal damage during lithotripsy by use of a thermosensitive bio-adhesive hydrogel. The described method dramatically improved the efficiency and effectiveness of stone clearance compared to conventional techniques while providing protection to the urothelium from potentially damaging temperature spikes.

Various devices related to a therapeutic ultrasound device for use during a medical procedure to cauterize tissue are disclosed. The therapeutic ultrasound device can include an inner tube assembly and an outer tube assembly. The device can further include a tissue engagement assembly that is secured to the distal end of the inner tube and the distal end of the outer tube. The tissue engagement assembly includes a plurality of transducers configured to provide therapeutic ultrasound. The device can include a housing assembly that is secured to the proximal end of the inner tube and the proximal end of the outer tube. The housing assembly can include a handle configured to actuate the inner tube relative to the outer tube to engage and disengage the tissue engagement assembly.

Methods and devices for treating erectile dysfunction are disclosed. Methods are aimed at reducing blood outflow from penile tissue by delivering energy to specific penile tissue that controls blood outflow from the penile tissue and causing remodeling of the specific penile tissue. Devices may be configured to generate RF energy and to apply the generated RF energy to a penis to thereby elevate a temperature of internal penile tissue above a predetermined temperature value while maintaining a penile surface below a predetermined temperature threshold. The predetermined temperature value may be set to initiate synthesis and/or a regeneration of collagen fibers in a collagen-rich penile connective tissue and/or to increase oxygenation of endothelial cells, initiate angiogenesis and neovascularization in a vascular penile tissue. Additionally, electrical penile stimulation is disclosed, possibly applicable in conjuncture with the erectile dysfunction treatment.
