    摘要: A method and structure for notifying clinicians with patients with implantable medical devices (IMDs), about recalls and upgrades, therapy improvements, longevity estimates/improvements, and follow-up frequency recommendations is implemented in an interactive preferably wireless communications system involving a preferably web-enabled remote expert station. Either the clinician or the patient may initiate and access the remote expert station. During such communications, the patient's IMDs are evaluated against a first database comprising patient data and a second database comprising statistical, survivability, probability projections. The patient or the clinician may also access a database containing patient-specific information including other device information. If one or more of the patient's IMDs matches with a recalled or an up-gradable unit such message is posted to the clinician and the patient. Remedial action is taken, by replacing the unit, upgrading/reprogramming the unit, adjusting the patient's follow-up timing to thereby ensure effective and safe therapy and clinical care.

    摘要: An Implantable Medical Device (IMD) for controllably releasing a biologically-active agent such as a drug to a body is disclosed. The IMD includes a catheter having one or more ports, each of which is individually controlled by a respective pair of conductive members located in proximity to the port. According to the invention, a voltage potential difference generated across a respective pair of conductive members is used to control drug delivery via the respective port. In one embodiment of the current invention, each port includes a cap member formed of a conductive material. This cap member is electrically coupled to one of the conductive members associated with the port to form an anode. The second one of the conductive members is located in proximity to the port and serves as a cathode. When the cap member is exposed to a conductive fluid such as blood, a potential difference generated between the conductors causes current to flow from the anode to the catheter, dissolving the cap so that a biologically active agent is released to the body. In another embodiment of the invention, each port is in proximity to a reservoir or other expandable member containing a cross-linked polymer gel of the type that expands when placed within an electrical field. Creation of an electric field between respective conductive members across the cross-linked polymer gel causes the gel to expand. In one embodiment, this expansion causes the expandable member to assume a state that blocks the exit of the drug from the respective port. Alternatively, the expansion may be utilized to assert a force on a bolus of the drug so that it is delivered via the respective port. Drug delivery is controlled by a control circuit that selectively activates one or more of the predetermined ports.

    摘要: Power consumption in medical and battery powered devices is reduced through the use and operation of multiple digital signal processing systems and through the application of different supply voltages to analog and digital circuits, respectively. Each processor of the multiple systems performs at least one particular function in a predetermined time period. The multiple digital signal processors of such systems can be operated at lower clock frequencies relative to those that would be required by one of such processors to complete the multiple functions within the predetermined time period. With reduced clock frequency, power consumption is reduced. Further, with reduced clock speed, supply voltages applied to such digital signal processors may also be reduced. A source applies a first fixed supply voltage to the digital circuits of the medical or battery powered device and a voltage generation circuit (e.g., a charge pump circuit) having the first fixed supply voltage applied thereto is used for generating a second fixed supply voltage to be applied to analog circuits of the device. Power consumption may also be reduced through the operation of circuits at clock speeds of lower levels to adequately complete desired functions during predetermined time periods (e.g., blanking interval, upper rate interval, etc.) just-in-time prior to subsequent required functional processes; by providing supply voltages tailored for various circuits of an integrated circuit; by operating two or more circuits of an integrated circuit at different clock frequencies; by changing the supply voltage level “on the fly” as required by specific circuit timing functions required for various circuitry based on clock frequencies used to control operation of such circuitry; and/or by tailoring back gate bias or adjusting back gate bias “on the fly” for circuits based on the supply voltage level applied to the circuits.

    摘要: Power consumption in medical and battery powered devices is reduced through the use and operation of a data monitor which measures, senses or detects signals, inputs or outputs in a medical device before they are input to a principal or main digital signal processor, controller or microprocessor. In response to detecting or measuring such a signal which meets certain amplitude, frequency and/or phase characteristics, the data monitor directs or controls clock or voltage supply circuits to increase or decrease clock frequency, or to increase or decrease the voltage provided to certain circuits within the medical device. The clock frequencies and/or voltages so employed are tailored to reduce the amount of power consumed by the medical device while preserving computational performance.

    摘要: Methods and apparatus for confirming programming of implantable medical device (IMD) operating parameter values and operating modes by emission of audible sounds by the IMD are disclosed. The IMD includes an audio transducer that emits audible sounds including voiced statements or musical tones stored in analog memory correlated to a programming or interrogation operating algorithm or to a warning trigger event. The audible sounds can comprise the sole uplink transmission or may augment the contemporaneous uplink RF transmission of stored data, and/or programmed operating modes and parameters and/or device operations and states in an interrogation or during programming. To conserve energy, the audible sounds accompanying interrogation and programming of the IMD are at a low volume that preferably cannot be heard without use of an external audio amplifier or stethoscope. Voiced statements warning of battery energy depletion or imminent delivery of a therapy are emitted at a higher volume that is sufficient to be heard by the patient, so that the patient can take appropriate action. The volume of audible sounds confirming programmed changes made by a patient using a limited function programmer or magnet is also increased so that the patient can hear them.
