    摘要： An implantable sensor device (105), such as a pressure monitor, is implanted in the left ventricle (LV) (135), in other heart chambers, or elsewhere, from which it wirelessly communicates pressure information to a remote communication device (140). The sensor device can be implanted using a placement catheter (600), an endoscope, or a laparoscope. The device can be secured entirely within the LV or heart wall, such as by using a corkscrew (312A), a helical anchor, a harpoon (312B), a threaded member, a hook, a barb, a fastener, a suture, or a mesh (312C) or coating for receiving fibrous tissue growth. The implantable sensor device (105) provides less invasive chronic measurements of left ventricular blood pressure or other physical parameters. The wireless communication techniques include radio-telemetry, inductive coupling, passive transponders, and using the body as a conductor (referred to as 'intracorporeal conductive communication' or a 'personal area network'). Data from the receiver is downloadable into a computer for analysis or display.

    摘要： Devices and methods for left ventricular or biventricular pacing plus left ventricular pressure measurement. For example, a pacing lead having a combined electrode and pressure sensor assembly may be used for left ventricular (LV) pacing and pressure measurement. The assembly may include one or more electrodes, a pressure sensor, and a pressure transmission catheter. Such a pacing lead is particularly suitable for biventricular pacing and may be incorporated into a cardiac resynchronization therapy (CRT) system, for example.

    摘要： Embodiments of the present invention provide a device with an integrated low-noise parametric amplifier using a CCD-based structure with minimal noise gain. In one embodiment, a device which may be used for monitoring and/or diagnosing a human or an animal body comprises a CCD-based device including a first gate forming a first capacitor and a second gate forming a second capacitor, the first capacitor having a surface area larger than a surface area of the second capacitor; and a controller configured to input a signal to the CCD-based device; convert the input signal into a charge packet having a voltage associated therewith; transfer the charge packet from the first capacitor to the second capacitor of the CCD-based device, the voltage associated with the charge packet being multiplied by a ratio of the surface area of the first capacitor divided by the surface area of the second capacitor; and produce an amplified output signal from the multiplied voltage.

    摘要： A device measures pressures in animals and humans and includes a pressure transmission catheter (22) filled with a pressure transmitting medium (26) and implantable in an area having a physiological pressure. A transducer (30) communicates with the pressure transmitting medium (26) to provide a pressure signal representing variations in the physiologic pressure on electrical wires (34). A connecting catheter (36) carries the electrical wires (34) to signal processing and telemetry circuitry (38), which transmits a telemetry signal representing the pressure signal to a receiver external to the animal or human. A housing (44) holds the signal processing and telemetry circuitry (38), but the transducer (30) is remote from the housing (44). The device performs measuring of venous pressure, pulmonary pressure, bladder pressure, or intracranial pressure without significant head pressure artifact and with a sufficient dynamic response. One embodiment of the catheter (22) includes a multi-durometer stem.
