BLOOD PUMP
20220323743 · 2022-10-13 ·

A self-contained peristaltic pump includes a flexible flow conduit with a plurality of circumferential and/or longitudinal shapechange elements distributed longitudinally and/or transversely along the longitudinal axis of the flow conduit. The activations of the shapechange elements result in the positive displacement of fluid in the anterograde direction (i.e. from the anterior end of the pump to the posterior end).

Implantable pump system having a rectangular membrane

An implantable pump system is provided, including an implantable blood pump suitable for use as a partial support assist device, the system further including an extracorporeal battery and a controller coupled to the implantable pump, and a programmer selectively periodically coupled to the controller to configure and adjust operating parameters of the implantable pump. The implantable pump includes a flexible membrane coupled to an electromagnetic actuator including a magnetic assembly and electromagnetic assembly, so that when the electromagnetic assembly is energized, the electromagnetic assembly causes wavelike undulations to propagate along the flexible membrane to propel blood through the implantable pump. The controller may be programmed by a programmer to operate at frequencies and duty cycles that mimic physiologic flow rates and pulsatility while operating in an efficient manner that avoids thrombus formation, hemolysis and/or platelet activation.

Enhancing left ventricular relaxation through neuromodulation
11623093 · 2023-04-11 · ·

Neuromodulation is used to enhance left ventricular relaxation and/or left ventricular contractility, during contemporaneous use of a mechanical circulatory support device to increase cardiac output or aid in unloading the heart. An exemplary neuromodulation system includes a therapy element positionable in proximity to at least one nerve fiber, and a stimulator configured to energize the therapy element to delivery therapy to the at least one nerve fiber such that left ventricular relaxation and left ventricular contractility are contemporaneously enhanced.
