Abstract: A device and system for simulating normal and disease state cardiovascular functioning, including an anatomically accurate cardiac simulator for training and medical device testing. The system and device uses pneumatically pressurized chambers to generate ventricle and atrium contractions. In conjunction with the interaction of synthetic valves, which simulate mitral and aortic valves, the system is designed to generate pumping action that produces accurate volume fractions and pressure gradients of pulsatile flow, duplicating that of a human heart. Through the use of a control unit and sensors, one or more parameters, such as flow rates, fluidic pressure, and heart rate, may be automatically controlled, using feedback loop mechanisms to adjust parameters of the hydraulic system to simulate a wide variety of cardiovascular conditions including normal heart function, severely diseased or injured heart conditions, and compressed vasculature, such as hardening of the arteries.

Abstract: A method of restoring perfusion to a blood vessel with an obstruction. The method includes delivering an expandable member into the blood vessel, said expandable member having a tubular mesh defined between a proximal end and a distal end; causing the expandable member to expand and compress the obstruction; and dislodging the obstruction to restore blood flow through the blood vessel.

Abstract: The present invention describes a device and system for simulating normal and disease state cardiovascular functioning, including an anatomically accurate left cardiac simulator for training and medical device testing. The system and device uses pneumatically pressurized chambers to generate ventricle and atrium contractions. In conjunction with the interaction of synthetic valves, which simulate mitral and aortic valves, the system is designed to generate pumping action that produces accurate volume fractions and pressure gradients of pulsatile flow, duplicating that of a human heart.

Abstract: A method of increasing blood flow through an obstructed blood vessel includes providing an expandable member substantially made of a mesh having a plurality of interstices. The expandable member is inserted into the blood vessel, positioned within the blood vessel with the proximal member end upstream of the distal member end and the member body located radially adjacent at least a portion of an obstruction, and expanded to bring at least a portion of the member body into contact with the obstruction. An outward radial force is exerted on the obstruction to dislodge at least one fragment from the obstruction and to enhance blood flow through the blood vessel past the obstruction. The at least one fragment is passed through at least one interstice of the member body in the radial direction, and is selectively retained within the expandable member.

Abstract: A system, method, computer-readable medium, apparatus, and device for simulating placement of an expandable device in a cavity is provided. For example, a three or more dimensional image of a cavity, e.g., a tubular cavity, geometry is acquired. A centerline of the cavity, and a perimeter of the cavity based on the centerline of the cavity and the three-dimensional image of the cavity geometry, are determined. The length of a wire of the expandable device as the wire rotates along the perimeter of the cavity in a deployment direction is determined. A pitch of the rotation of the wire based on a local diameter at the centerline site of rotation and in-air parameters of the expandable device is determined. A deployed device length of the expandable device along the centerline of the cavity is determined. A processor is usable to determine and/or calculate each of the above.
