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.
