Abstract
An emergency system for treatment of a patient (20) experiencing an acute vascular obstruction, employing a non-invasive vibrator (10), optimally in conjunction with drugs, for disrupting and lysing thromboses, relieving spasm (if associated), and thereby restoring blood perfusion. Vibrator (10) is operable in the sonic to infrasonic range, with a source output of up to 15 mm. For acute myocardial infarction cases, a pair of contacts (12), are advantageously placed to bridge the sternum at the fourth intercostal space. Vibration is initiated at 50 Hz (or any frequency, preferably within the 20-120 Hz range), and is ideally adjusted to a maximal amplitude (or force) deemed tolerable and safe to the patient (20), preferably with the administration of thrombolytic agents or other form of drug therapy. A synergistic effect is achieved between vibration and drugs to facilitate the disruption of thromboses, relieve spasm, and restore blood perfusion. In a variation, ultrasonic imaging may be used to direct vibration therapy.
