Improving cell therapy and tissue regeneration in a patient suffering from a cardiovascular or a neurological disease by treating a tissue of the patient with shock waves and / or applying to the patient a therapeutically effective amount of stem cells and / or progenitor cells. Such treatment increases expression of chemoattractants, pro-angiogenic factors, and pro-survival factors. The chemoattractants can be, for example, vascular endothelial growth factor (VEGF) or stromal cell derived factor 1 (SDF-1). For example, the treated tissue can be located in the patient's heart or in a skeletal muscle of the patient, and the shock waves can be extracorporeal shock waves (ESW) or intracorporeal shock waves. The cardiovascular disease can have an ischemic or non-ischemic etiology. For example, the cardiovascular disease can be a myocardial infarction, ischemic cardiomyopathy, or a dilatative cardiomyopathy. For example, the neurological disease can be a peripheral neuropathy or neuropathic pain.

Medical devices with novel spark gap electrode designs, able to control manually or automatically the electrodes gap are provided. These devices are used to generate a shock wave created by the rapid expansion and collapse of a plasma bubble that is formed between two spark gap electrodes placed in a special liquid medium, when a high differential voltage (kV) is applied to the electrodes. The resulting shock wave impacts a reflector to direct the energy into the body of an animal or a human toward the desired treatment location. This electro-hydraulic principle to create acoustic shock waves as a method of treatment is in use in the medical (lithotripsy, orthopedic use, wound treatment, burns, post-operative treatment, pain treatment, diagnosis, skin and organ transplantation supporting devices, arteriosclerosis treatment), cosmetic (treatment of scars and cellulite) and veterinary (treatment of musculoskeletal disorders) fields.

An apparatus, method and system for classifying a shockwave is described, particularly for use in an Extracorporeal Shockwave Lithotripsy (SWL) system. The method for classifying a shockwave generated and directed towards a stone in an extracorporeal shockwave lithotripsy treatment comprises receiving an acoustic signal at a passive unfocused acoustic sensor, determining whether at least one characteristic of the received acoustic emissions exceeds a respective pre-determined threshold value, and classifying the shockwave as effective or ineffective in dependence upon said determination. A method for predicting the outcome of an SWL treatment is also described.

The present invention relates to a method for treating the kidney with extracorporeal shockwaves in a noninvasive manner and in particular, to such a method for the treatment of the nephrons about the glomerulus.

A method and device producing extracorporeal shockwaves for the treatment of erectile dysfunction.

The invention discloses an extracorporeal shock wave lithotripter adopting ultrasonic waves to position treatment points and a positioning method thereof. A B ultrasound machine is mounted, so that accurate judgment for treatment points of the extracorporeal shock wave lithotripter by the B ultrasound machine becomes very difficult. Four ultrasonic transducers of the extracorporeal shock wave lithotripter disclosed by the invention are all fixed on a treatment head, and acoustic axes of the four ultrasonic transducers pass through the focus of the treatment head; the four ultrasonic transducers are connected with transducers cables; the four ultrasonic transducers cables extend out of a housing of the treatment head; one end of a cable lead is connected with a shock wave generation source; the other end of the cable lead extends out of the housing of the treatment head. The stone positioning method disclosed by the invention comprises the following steps: echoes of generated shock waves on a stone are used as a detection signal, and a signal acquisition system is used to process and analyze a received signal, so that the position of the stone and deviation conditions of the treatment points of the extracorporeal shock wave lithotripter are determined, and a basis is provided for adjusting the position of the extracorporeal shock wave lithotripter. According to the invention, the fact that shock waves and echo are spread in the same path is guaranteed and the ultrasonic detection accuracy is improved.

The invention discloses an extracorporeal shock wave lithotripter and a charge-discharge circuit for same. The extracorporeal shock wave lithotripter comprises a shock wave generation device which comprises a charging circuit and a discharging circuit; the charging circuit is formed by a resistor and a capacitor; the discharging circuit is formed by the capacitor, a high voltage switch and a shock wave source device; the capacitance of the capacitor is 1.5 to 2.5 microfarads; the focus pressure peak of the shock wave generated through discharging on the shock wave source device through the capacitor is 6 to 30 MPa; the bottom pulse width is 3 to 4 microseconds. The extracorporeal shock wave lithotripter has the advantages of enabling generated shock wave to be wide in bottom pulse and smooth in pressure, enabling the focus pressure peak of the shock wave to be small, enabling calculus to be fragmented through stress concentration and meanwhile reducing side effect to human bodies.
