Non-invasive reperfusion system by deformation of remote, superficial arteries at a frequency much greater than the pulse rate

InactiveUS20130281897A1Effective researchEffective clinical toolUltrasound therapyOrgan movement/changes detectionPULMONARY EMBOLUSThrombus
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.

Use of probes for unbound metabolites

Methods of determining levels of unbound metabolites are disclosed. Probes derived from fatty acid binding protein muteins are described that bind preferentially to a number of unbound metabolites including oleate, stearate, linoleate, palmitate, arachidonate and unconjugated bilirubin. A profile for a patient is determined using one or more of the described probes. The profile is useful in diagnosis of disease, particularly myocardial infarction, non-alcoholic fatty liver disease (NAFLD), diabetes, stroke, sepsis and neonatal jaundice. The responses of multiple probes to a test sample are used to classify the degree of acute coronary syndrome by comparison to multi-probe profiles generated from unstable angina, non ST elevation myocardial infarction, and ST elevation myocardial infarction.

Three dimensional imaging ultrasound with microbubbles to enhance reflow in ST elevation myocardial infarction

The present invention relates to an improved method for accelerating restoration of blood flow in treatment of an acutely thrombosed coronary artery by employing real time transthoracic 3D ultrasonic volume imaging at or near the base of the heart, and / or proximate the basal aspect of the associated left ventricular regional wall motion abnormality. Ultrasonic pulses provided by 3D imaging uniquely and necessarily deliver ultrasound to a broad target volume to stimulate the coronary arteries (which are difficult to image with ultrasound, and comprise tortious three dimensional structures), in view to providing an agitative and clot disruptive effect to a hidden, culprit, thrombosed, coronary vessel. In the preferred embodiment an intravenous microbubble solution is concurrently administered with 3D ultrasound which creates a dramatic synergy in disrupting the culprit thrombosis. Further incorporation of intravenously administered thrombolytics and co-use of transthoracic low frequency sonic vibration massage along with 3D ultrasonic imaging and microbubbles (including whereby thrombolytics are contained within microbubbles) to expedite initial reflow and facilitate microvascular flow (in avoidance of the no-reflow phenomenon following epicardial vessel recanalization) are also discussed.
