Patent number: 11682320Abstract: 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.Type: GrantFiled: September 20, 2019Date of Patent: June 20, 2023Assignee: Mentice, ABInventors: Chandramouli Sadasivan, Baruch B. Lieber, Brandon Joseph Kovarovic, Louie E. Abejar, Henry Woo, David Jeffrey Carson, David Fiorella, Michael Romeo, Gary Bunch, Karl Keppeler

The system and device uses pneumatically pressurized chambers to generate ventricle and atrium contractions. In conjunction with the interaction of synthetic 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 remote handheld electronic controller and manual adjustments from a main control panel, the air pressure level, fluidic pressure, and heart rate is controlled to induce contractions that simulate a wide variety of heart conditions ranging from normal heart function to severely diseased or injured heart conditions.Type: GrantFiled: January 31, 2012Date of Patent: November 10, 2015Assignee: Vascular Simulations, LLCInventors: David Jeffrey Carson, Baruch B.
