Portable ventricular assist system with a multi-channel optical pressure sensor

Abstract

A portable ventricular assist system may comprise a heart pump and at least one hardware controller. The heart pump may comprise a rotor, a motor configured to drive rotation of the rotor at one or more speeds, a first optical pressure sensor configured to detect a first pressure signal, and a second optical pressure sensor configured to detect a second pressure signal. The at least one hardware controller may comprise a primary power source, a secondary power source, at least one light-emitting diode (LED) coupled to the first optical pressure sensor via at least one first optical fiber, and the second optical pressure sensor via at least one second optical fiber. The at least one hardware controller may further comprise at least one hardware processor configured to determine a differential pressure based, at least in part, the first pressure signal and the second pressure signal.
