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

    摘要： Systems and methods for monitoring intravascular pressure of a patient. The system includes a pressure sensor and catheter assembly having a pressure sensor portion and a transdermal catheter portion. The transdermal catheter portion has a fluid filled lumen and a distal barrier to maintain patency. A transmitter unit may be connected to the pressure sensor portion via a lead. The transmitter unit transmits pressure data to a remote receiver unit that may communicate (directly or indirectly) with a cable management device, a data acquisition device, a monitoring instrument, a computer, a modem, a telecommunication line, a network, etc. In addition, the system may include means to correct for pressure variations due to any difference in elevation between the sensor assembly and the heart.

    摘要： Embodiment of the invention provide a technique for detecting endoleakage of an abdominal aortic aneurism (AAA) stent graft on a relatively frequent basis at home or the clinic without the safety risks and/or costs associated with current approaches. In one embodiment, an apparatus for detecting leakage in an AAA graft comprises: an electrode array having a plurality of electrodes distributed over and coupled with a surface of the AAA graft; and an electrical circuit configured to generate a stimulus voltage or current to be applied between sets of the plurality of electrodes of the electrode array and measure an impedance between the sets of the plurality of electrodes. The sets of electrodes for measuring the impedance are same as or different from the sets of electrodes for applying the stimulus voltage or current. A leakage is detected by a decrease in the impedance measured by the electrical circuit.

    摘要： A vascular access port system including means for detecting and indicating the presence or absence of a needle. The detecting and indicating means may be carried in whole or in part by one of or both of the needle and/or the vascular access port. The detecting and indicating means may utilize a conductive needle, a mechanical switch, a magnetic switch, a Hall effect sensor, an electric field, a magnetic field, or an inductor, for example, for detection purposes. The vascular access port system permits the practitioner to confirm that the needle has been correctly inserted into the VAP, and notifies the patient and/or practitioner if the needle has been accidentally withdrawn.
