  • Publication number: 20210205598
    Abstract: A system configured to be at least partially implanted along an aorta includes an inelastic, static member and a pinching member. The pinching member is configured to receive an activation signal at an activation rate and in response to the activation signal, repeatedly compress the aorta at the second location at the activation rate to pump fluid within the aorta in a desired pumping direction. The system is configured to selectively control wave reflections in order to achieve both improved wave dynamics to reduce cardiac load and increased (or at least non-diminished) blood flow to targeted organs within the cardiovascular system.

  • Publication number: 20210154385
    Abstract: An artificial chamber including a first conduit, a second conduit, a third conduit, and a wall defining a space; in which the first conduit and the second conduit are positioned opposite one another; in which the third conduit is opposite the wall; and in which the wall has a concave surface is disclosed. The chamber can be part of a system for providing pulmonary support. The system includes the chamber and a first pump connected to the third conduit, and connected to a fourth conduit; in which the chamber receives fluid via the first conduit and the second conduit, in which the first pump receives fluid from the chamber via the third conduit; and in which the fourth conduit transports fluid from the first pump to a first blood vessel. Methods of making a chamber and a system, and methods of using the chamber and system are also disclosed.

  • Publication number: 20200359912
    Abstract: A non-invasive and convenient method and apparatus for approximation of left ventricular end diastolic pressure (LVEDP) can be used in both hospital/clinic environments and nursing home or home environments. The method and apparatus use non-invasive sensors and a new “cardiac triangle” computational method to obtain an approximation of LVEDP. The computational method uses hemodynamic and electrocardiogram (ECG) waveforms as input, which can be collected by a portable device or devices.
