Apparatuses and methods for electrohydraulic generation of shockwaves at a rate of between 10 Hz and 5 MHz, and/or that permit a user to view a region of a patient comprising target cells during application of generated shockwaves to the region. Methods of applying electro-hydraulically generated shockwaves to target tissues (e.g., for reducing the appearance of tattoos, treatment or reduction of certain conditions and/or maladies).

A device for shock wave production to treat a patient's body comprises a base with a condenser as power supply, an applicator having a pad, at least one piezo-element configured to generate a shock wave in response to a pulse of electric current having a pulse width, an acoustic lens configured to focus the shock wave, and a coil configured to increase the pulse width of the pulse of electric current.

The present invention provides enhanced ESWL efficacy for therapeutic and operational outcomes. Device behavior and performance data is measured in-situ and analyzed for both intra-procedure and inter-procedure breadth of regard such that both therapy optimization and maintenance optimization engines are provided an accurate and current assessment of ESWL system and device state and performance. This feedback and control provides the ability to compensate in real time for the current patient therapy and offline for future patient therapy for machine/therapy idiosyncrasies and realize continuous calibration of system/devices to the performance required for maximum ESWL patient efficacy.

A system, device and method for removing occlusive material from a bodily lumen comprising a catheter with a distally mounted and fluid-fillable litho-cushion in operative connection with at least one forward-focusing reflector. The catheter comprises a lumen with an electrode pair housing disposed in watertight engagement with the lumen at or near the distal end of the lumen, the electrode pair housing comprising at least one electrode pair. The at least one electrode pair is in wired communication with a pulse generator, wherein the electrode pair is configured to generate an electrical arc between the electrodes of the electrode pair with subsequent generation of a shock wave. The shock wave is directed distally out of the catheter lumen and focused forward and distally away from the catheter lumen by the at least one reflector toward the targeted occlusive material.

Acoustic signal transmission couplants for use in tomographic, large aperture ultrasound imaging and therapeutic ultrasound are described that couple acoustic signal transducers to body structures for transmitting and receiving acoustic signals. The acoustic signal transmission couplants can conform to the receiving medium (e.g., skin) of the subject such that there is an acoustic impedance matching between the receiving medium and the transducer. In one aspect, an acoustic coupling medium includes a hydrogel including polymerizable material that form a network structured to entrap an aqueous fluid inside the hydrogel. The hydrogel is structured to conform to the receiving body, and the acoustic coupling medium is operable to conduct acoustic signals between acoustic signal transducer elements and a receiving medium when the hydrogel is in contact with the receiving body such that there is an acoustic impedance matching between the receiving medium and the acoustic signal transducer elements.

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.

A method is disclosed for treating calcified lesions within a wall of a blood vessel. The first step includes breaking apart a calcified lesion using a plurality of shockwaves generated in an angioplasty balloon of an angioplasty catheter device. The angioplasty balloon is dilated via a fluid to a first extent to fit against at least a portion of the wall of the blood vessel. A plurality of electrical pulses are delivered to a pair of electrodes disposed within the fluid inside the balloon. The electrical pulses have an amplitude sufficient to create plasma arcs in the fluid to generate shockwaves that are conducted through the fluid and through the balloon to the blood vessel, to crack the calcified lesion. After breaking apart the calcified lesion, the angioplasty balloon is allowed to further expand to a second extent greater than the first extent, thereby expanding an opening in the blood vessel.

Devices and methods for treating human cranial hair loss using extracorporeal acoustic shock waves are disclosed. The shock wave device optionally includes a proximal surface, a plurality of shock wave generators disposed on the surface, and a coupling assembly configured to transmit shock waves to a user's scalp.

A therapy system includes a therapy source (2) emitting radiation or waves, an ultrasound probe (14), a patient rest as well as a multi-axis positioning system (X, Y, Z) with several drives, by way of which the patient rest and the therapy source (2) can be moved to one another in all three spatial directions. A control device (26) is coupled to the ultrasound probe (14) and configured such that in at least one operating mode, the control device (26) simultaneously activates the drives of the multi-axis positioning system (X, Y, Z) such that the patient rest is moved relative to the therapy source along a selectable movement path (B) which lies within the plane of an ultrasound picture (20) which is currently recorded by the ultrasound probe (14). A method for positioning a patient rest relative to a therapy source is also provided.
