Abstract
A peripheral memory patch apparatus for attachment to a patient'"'"'s skin includes a high capacity memory for storing physiologic data uplinked from an implantable medical device. A resilient substrate provides support for a memory, microprocessor, receiver, and other electronic components. The substrate flexes in a complimentary manner in response to a patient'"'"'s body movements. The substrate is affixed to the patient'"'"'s skin with the use of an adhesive which provides for comfort and wearability. The low profile peripheral patch apparatus is preferably similar in size and shape to a standard bandage, and may be attached to the patient'"'"'s skin in an inconspicuous location. A status indicator provides for a visual, verbal, or tactile indication of the operational status of the peripheral memory patch. Uplinking of physiologic telemetry data from the internal memory of an implantable medical device to the peripheral memory patch is initiated in response to a transfer signal produced by the peripheral memory patch. The transfer signal may be generated by the implantable medical device or upon actuation of a switch by the patient. Various telemetry techniques including radio frequency, acoustic, and body bus telemetry techniques, may be employed to transfer information between the implantable medical device and the peripheral memory patch.
