20160128869 | CYCLIC APERTURE FLOW REGULATOR SYSTEM - A cyclic aperture flow regulator system is disclosed to control flow exiting from a body cavity during surgery in a way that post-occlusion surges are effectively suppressed. The system is composed by an adjustable fluid aperture installed in a fluid path connecting the aspiration port of a surgical probe with a vacuum source, the probe to be inserted in a body cavity. The cross-sectional area of the fluid aperture can be modified by the action of an actuator portion driven by a controller. The controller commands the actuators in the actuator portion to modify the cross-sectional area of the adjustable fluid aperture in cycles. Each cycle of aperture dimension fluctuation includes at least one segment where the fluid aperture cross-sectional area is substantially reduced. The segment of each cycle where the cross-sectional area of the fluid aperture is substantially reduced can optionally include a transient complete closure of the aperture. The cycles of fluid aperture fluctuation are programmed to occur at a rate fast enough to produce a substantially steady flow, with minimum flow ripple and pressure ripple. Flow rate across the cyclic aperture flow regulator system is a function of the vacuum level of the vacuum source and can be regulated by adjusting the level of the vacuum. Flow rate across the cyclic aperture flow regulator system is also a function of the RMS value of the cross-sectional area of the fluid aperture and can be regulated by adjusting the amplitude of the waveform of each cycle. | 05-12-2016 |
20160129233 | 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. | 05-12-2016 |
