Abstract
Preferred systems for assisting clearance of an acutely thrombosed artery substantially surrounded by boney external body surfaces which are resistant to deformative displacement relative to the thrombosed artery by the application of external percussive force are described. The method consists of applying targeted, localized, non-invasive, high infrasonic to low sonic frequency vibratory percussion with a serial impact frequency much greater than the pulse rate of a patient being treated, the percussion directed towards a remote, preferably superficial “target vessel” residing palpably close to the skin surface. Marked vessel deformations with resultant blood pressure and flow fluctuations are thereby induced by the percussion within the target vessel which propagate to the acutely thrombosed artery to provide localized agitation and turbulence to assist thrombolytic and/or IV microbubble delivery and effectiveness in facilitating reperfusion. Preferred apparatus for treatment of ST elevation myocardial infarction, acute ischemic stroke and acute pulmonary embolus are presented.
