20090312650 | IMPLANTABLE PRESSURE SENSOR WITH AUTOMATIC MEASUREMENT AND STORAGE CAPABILITIES - Methods for activating implantable medical devices within a patient's body are disclosed. An illustrative method includes activating an implantable medical device from a low-power state to an awake state in response to a scheduled time event, sensing one or more pressure measurements within the body, computing an average pressure measurement based on the sensed pressure measurements, storing the average pressure measurement within a memory of the implantable medical device, and then returning the device to the low-power state. A triggering event such as the detection of patient activity or motion can also be used to activate the implantable medical device between the low-power state and an active state. | 12-17-2009 |
20100016840 | IMPLANT ASSIST APPARATUS FOR ACOUSTICALLY ENABLED IMPLANTABLE MEDICAL DEVICE - Devices, systems and methods for delivering and positioning an implantable medical device and for evaluating an acoustic communication link are disclosed. An illustrative system includes a catheter adapted to contain an implantable device with a biosensor and an acoustic transducer configured to transmit an acoustic signal, and an implant assist device in acoustic communication with the implantable device via an acoustic communication link. The implant assist device includes an acoustic transducer adapted to receive the acoustic signal transmitted by the implantable medical device, and control/processing circuitry configured to evaluate a performance of the acoustic link. | 01-21-2010 |
20100023091 | ACOUSTIC COMMUNICATION OF IMPLANTABLE DEVICE STATUS - An operational status of an implantable medical device is monitored. The implantable medical device includes a biosensor and an acoustic transducer adapted to transmit and receive acoustic signals. An acoustic link is established with the implantable medical device via a remote acoustic transducer adapted to receive acoustic signals from the implantable medical device and to transmit acoustic signals. Data related to the operational status of the implantable medical device is received from the implantable medical device via the acoustic link. | 01-28-2010 |
20100042177 | PERFORMANCE ASSESSMENT AND ADAPTATION OF AN ACOUSTIC COMMUNICATION LINK - Systems and methods for adapting the performance of an acoustic communication link with an implantable medical device (IMD) are disclosed. An illustrative method includes initiating an acoustic link with the IMD, measuring an initial performance of the acoustic link, determining whether the initial performance of the acoustic link is adequate, adjusting an operating parameter related to the acoustic link in the event the initial performance of the acoustic link is inadequate, measuring a performance of the acoustic link in response to the adjusted operating parameter, and setting the operating parameter to a prior setting if the measured performance of the acoustic link does not improve in response to the adjusted operating parameter. | 02-18-2010 |
20100106028 | METHODS AND SYSTEMS FOR RECHARGING IMPLANTABLE DEVICES - Methods, systems, and apparatus for recharging medical devices implanted within the body are disclosed. An illustrative method of recharging an implanted medical device includes delivering a charging device to a location adjacent to the implanted medical device, activating a charging element coupled to the charging device and transmitting charging energy to a receiver of the implanted medical device, and charging the implanted medical device using the transmitted charging energy from the charging device. | 04-29-2010 |
20110082376 | PHYSIOLOGICAL BLOOD PRESSURE WAVEFORM COMPRESSION IN AN ACOUSTIC CHANNEL - Methods, systems and devices for processing blood pressure measurements are disclosed. An illustrative method includes transmitting a command to an implantable medical device including a blood pressure sensor. The method includes receiving a response from the implantable medical device, the response indicating that the device initiated the sensing of blood pressure measurements. The method includes receiving one or more data packets from the implantable medical device. The one or more data packets can include a base pressure measurement that is representative of a starting point of a blood pressure waveform. The one or more data packets further include a delta value measurement representative of a difference between another blood pressure measurement and the base pressure measurement, or a difference between a current measurement and one or more previous measurements. Additionally, the method includes generating a pressure waveform from the one or more data packets. | 04-07-2011 |
