Abstract

The operational and functional aspects of one or more IMDs is controlled by physiological data acquired from an external device. Various externally deployed devices collect vital signals for transmission to the IMD. Upon receipt of the signals the IMD cooperatively modifies therapy and diagnostic procedures to be substantially compliant with the received signals. Further, the IMD may store some of the signals for future follow-up or patient data management as needed.

Claims

1. A system comprising:

at least one implantable medical device (“

IMD”

providing therapy delivery, said IMD including a processor controlling the delivery of therapy to a patient; and

an external sensor module having at least one physiological sensor adapted to operatively couple to a surface portion of a lower peripheral limb of the patient and operational to continuously collect physiological data of the patient wherein said external sensor module continuously transmits the continuously collected physiological data to the IMD;

wherein said IMD processor processes the physiological data to produce therapy delivery control signals in implementation of dynamic, closed-loop self-monitoring therapy delivery and wherein said external sensor module comprises a sock-based sensor and wherein said sock-based sensor is adapted to collect physiological data including at least one of;

a patient weight metric, a patient ankle-swelling metric, a patient activity metric.

2. The system of claim 1 wherein said at least one cardioverter/defibrillator IMD comprises one of:

a pacemaker, an implantable cardioverter/defibrillator, a drug delivery system, a nerve stimulator.

3. The system of claim 1 wherein said external sensor module transmits the physiological data to the IMD over a communication channel including RF signals.

4. The system of claim 1 wherein said physiological sensor is a piezoresistive force sensor.

5. A method comprising:

providing therapy delivery using at least one implantable medical device (“

IMD”

), said IMD including a processor controlling the delivery of therapy to a patient; and

continuously collecting physiological data of the patient using an external sensor module having at least one physiological sensor;

continuously transmitting the physiological data from said external sensor module to the IMD; and

processing the physiological data to produce one or more therapy delivery control signals in a dynamic, closed-loop, self-monitoring therapy delivery regime wherein said external sensor module comprises a sock-based sensor and wherein said sock-based sensor is adapted to collect physiological data including at least one of;

a patient weight metric, a patient ankle-swelling metric, a patient activity metric.

6. A method according to claim 5, wherein said at least one IMD comprises a pacemaker.

7. A method according to claim 5, wherein said external sensor module transmits the physiological data to the IMD over a communication channel including RF signals.

8. A method according to claim 5, wherein said at least one physiological sensor comprises a one of:

a pressure sensor, an oxygen saturation sensor, an acceleration sensor, an impedance sensing apparatus.
