BLOOD PUMP SYSTEM WITH ARTERIAL PRESSURE MONITORING
First Claim
Patent Images
1. A blood pump system, comprising:
- a blood pump having an inflow conduit for receiving blood from a left ventricle of a heart and an outflow conduit for returning blood to a circulatory system; and
a controller operably connected to said blood pump;
wherein said outflow conduit comprises a sensor located to detect a conduit pressure that is substantially the same as arterial pressure, and wherein said sensor is adapted to send a signal regarding said conduit pressure to said controller.

Abstract
Materials and methods related to blood pump systems are described. These can be used in patients to, for example, monitor arterial pressure, measure blood flow, maintain left ventricular pressure within a particular range, avoid left ventricular collapse, prevent fusion of the aortic valve in a subject having a blood pump, and provide a means to wean a patient from a blood pump.

12. A blood pump system, comprising:
-
a blood pump having an inflow conduit for receiving blood from a right ventricle or right atrium of a heart and an outflow conduit for returning blood to pulmonary circulation; and a controller operably connected to said blood pump; wherein said outflow conduit comprises a sensor located to detect a conduit pressure that is substantially the same as pulmonary artery pressure, and wherein said sensor is adapted to send a signal regarding said conduit pressure to said controller. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
