    摘要: The invention generally relates to heart pump systems. In some embodiments, a pressure sensor is provided with a heart pump, either at the inflow or the outflow of the blood pump. The heart pump may further include a flow estimator based on a rotor drive current signal delivered to the rotor. Based on the rotor drive current signal, a differential pressure across the pump may be calculated. The differential pressure in combination with the pressure measurements from the pressure sensor may be used to calculate pressure on the opposite side of the pump from the pressure sensor. In some embodiments, the pressure sensor is located at the outflow of the pump and the pump is coupled with the left ventricle. The differential pressure and pressure measurement may be used to calculate a left ventricular pressure waveform of the patient. With such a measurement, other physiological parameters may be derived.

    摘要: The present invention provides an energized ophthalmic device (150) with an active agent release system (105) and an associated method. The active agent release system can be suitable to dispense an active agent including, for example, a vitamin, lubricant, a saline, a solvent, and/or medicament, at one or more predetermined times, through the use of an energization element (100) contained in the ophthalmic device. The energization element may be a battery and/or an energy receptor antenna. The release of the active agent can be according to a signal received wirelessly, a predetermined time, and/or a sensed condition, which can cause an activation element to conduct a current to at least a portion of a metal cap under stress causing it to fold and thereby expose the active agent to a surrounding environment.

    摘要: A centrifugal pump system having an impeller rotating with first and second magnetic structures on opposite surfaces. A levitation magnetic structure is disposed at a ftrst end of a pump housing having a levitating magnetic field for axially attracting the first magnetic structure. A multiphase magnetic stator at a second end of the pump housing generates a rotating magnetic field for axially and rotationally attracting the second magnetic structure. A commutator circuit provides a plurality of phase voltages to the stator. A sensing circuit determines respective phase currents. A controller calculates successive commanded values for the phase voltages in response to the determined phase currents and a variable commutation angle. The angle is selected to correspond to an axial attractive force of the stator that maintains a levitation of the impeller at a centered position within the pumping chamber.

    摘要: A penis erection stimulation system comprises a fully implantable drug delivery device for delivering a drug in relation to a penis to achieve erection of the penis. The drug delivery device may comprise a catheter adapted to be implanted in the corpora cavernosa of a penis or in close proximity thereto in order to deliver drugs through said catheter. Alternatively, one or more infusion needles may be disposed within and implanted along with one or more housings adjacent the patient's left and right corpora cavernosa. A reservoir and a pump may also be implanted inside the patient's body to supply the infusion needle with infusion liquid. A drive unit also adapted for implantation inside the patient's body is arranged for advancing and retracting the tip end of the infusion needle such that it penetrates the housing at least in two different penetration areas either simultaneously or in immediate time succession, thereby injecting drugs along with the infusion liquid into the patient's body for stimulating penis erection.
