Abstract:
Wireless sensors configured to record and transmit data as well as sense and, optionally, actuate to monitor physical properties of an environment and, optionally, effect changes within that environment. In one aspect, the wireless sensor can have a power harvesting unit; a voltage regulation unit, a transducing oscillator unit, and a transmitting coil. The voltage regulation unit is electrically coupled to the power harvesting unit and is configured to actuate at a minimum voltage level. The transducing oscillator unit is electrically coupled to the voltage regulation unit and is configured to convert a sensed physical property into an electrical signal. Also, the transmitting coil is configured to receive the electrical signal and to transmit the electrical signal to an external antenna.
Abstract:
The temporal correlation between a bioelectrical brain signal of a patient and patient motion data, such as a signal indicative of patient motion or a patient posture indicator, is displayed by a display device. In some examples, the patient posture indicator comprises a graphical representation of at least a portion of a body of the patient. In some examples, the temporal correlation between a bioelectrical brain signal, a signal indicative of patient motion, and a signal indicative of cardiac activity of the patient is displayed by the display device.
Abstract:
A personal wearable EEG monitor with a base part (1) having signal processing means (23),an electrode part (2) with at least two electrodes (11, 12) for measuring an EEG signal of a person. The electrode part(2)comprises means for converting the EEG signal into a digital signal. The EEG monitor comprises a databus for transferring data between the base part (1) and the electrode part (2) and for providing power from one part to the other. The databus is adapted for application of two electrical wires.
Abstract:
A magnetic field generating apparatus 20 is the magnetic field generating apparatus 20 that transmits a control signal by a magnetic field to a capsule endoscope 10 that performs control of start and stop according to the control signal. The magnetic field generating apparatus 20 includes a housing 25 including a storing section 21 in which the capsule endoscope 10 is arranged, a magnetic field generating section 42 that generates the magnetic field, and a shield section 26 that shields a leakage electromagnetic field leaking to an area other than the storing section 21 in the magnetic field generated by the magnetic field generating section 42.
Abstract:
A endovascular graft (30) having sensing devices (16) attached thereto to facilitate measurement of pertinent parameters within the vasculature into which the graft (30) is implanted. Power sources and transmitters (12) may be attached to the graft to facilitate transmission of measurements to a receiving device outside the patient's body. The sensing devices (16) may be electrically passive or integrated devices with measurement and transmission capability. The sensing devices may be attached to specific locations on the graft material or attached to the lumen, thereby providing pertinent parameters from critical points inside the vasculature, or may be dispersed over the surface of the graft material or within the lumen to provide a profile of pertinent parameters. The sensing devices (16) may be attached to the graft material with one suture (70) using a running stitch to minimize graft bulk and may be coated with a material to inhibit or control tissue growth.
Abstract:
A system for supplying energy to an implantable medical device when implanted in a patient's body can comprise an internal charger arranged to be implanted in the patient's body, the internal charger comprising a first coil. The system can further comprise an external charger arranged to wirelessly transmit energy to supply power to the internal charger, using a second coil. The system also comprises a wireless feedback system arranged to transmit feedback information from the internal charger to the external charger. The feedback information is based on information from at least one Radio Frequency Identification (RFID) transmitter. Hereby a user of the system can optimize the position of the external power supply in relation to the internal power supply based on the received feedback information. This in turn will result in a better and more robust energy transfer to the implanted medical device.
Abstract:
A system for tracking a device can include a medical device for placement in a target anatomy of a patient, one or more sensors in proximity to and connected to the medical device, wherein positioning data associated with the medical device is generated by the one or more accelerometric sensors, and a processor for determining at least one of a position and an orientation of the medical device based on the positioning data.
Abstract:
Die Anmeldung betrifft einen implantierbaren Biosensor (2), welcher eine mit einer Testflüssigkeit (104) gefüllte Messkammer (102) umfasst, die in der Lage ist, eine Änderung der Konzentration eines vorbestimmten Analyten oder Ionensorte in eine Änderung einer physikalischen Größe umzuwandeln. Hierbei ist die Messkammer durch wenigstens eine Membran (103) abgeschlossen, die für den Analyten oder Ionensorte durchlässig und für die Testflüssigkeit undurchlässig ist. Zudem ist der Biosensor mit wenigstens einem mikroakustischen Sensor ausgerüstet (105), der mit der Testflüssigkeit so wirkverbunden ist, dass er die mit der Konzentration des Analyten oder Ionensorte sich ändernde physikalische Größe detektieren kann. Des Weiteren erstreckt sie sich auf eine Sensoranordnung mit wenigstens einem solchen implantierbarer Biosensor, welche eine mit dem Biosensor drahtlos gekoppelte Abfrageeinrichtung umfasst.
