  • Physiological heart pump control
    Patent number: 6623420
    Abstract: A blood pump is joined in parallel flow between the left ventricle and aorta of a patient's heart. The pump includes an inlet pressure sensor and cooperating controller for measuring inlet pressure to the pump to control operation thereof. The controller adjusts speed of the pump in a closed loop control using feedback of the measured inlet pressure to conform operation of the pump with the natural cycle of the heart.

  • Pressure cuff
    Publication number: 20030097073
    Abstract: A pressure cuff includes a pad having a seat for receiving a vessel therealong through which a fluid under pressure flows. A pressure sensor is mounted inside the pad and includes a flexible flat diaphragm in the seat for engaging the vessel in flat contact therewith. A flexible strap is provided to clamp the pad in abutting contact with the vessel for measuring pressure through the wall thereof.

  • Dual pressure monitor
    Patent number: 6481292
    Abstract: A remote pressure sensor includes a probe having a chamber for holding a liquid. A flexible membrane is mounted in the probe. A conduit joins a reference cell to the chamber for holding the liquid. And, a reference pressure gauge is operatively joined to the conduit for measuring pressure of the liquid therein for use in referencing a primary pressure sensor through which fluid flows.

  • Notch diaphragm pressure sensor
    Patent number: 6367333
    Abstract: A pressure sensor includes a tube for channeling a fluid therethrough. A notched seat is disposed in an outer surface of the tube and is open at circumferentially opposite ends, with a flexible diaphragm at the bottom thereof. The diaphragm is planar, and blends at its perimeter coextensively with an arcuate inner surface of the tube. A gauge is mounted in the seat above the diaphragm for measuring flexure thereof under pressure of the fluid inside the tube.
