Abstract

A combined vascular access port and physiologic parameter monitoring device. The vascular access port and the monitoring device may be connected by a cooperative geometry. The vascular access port and the monitoring device may be implanted at the same time and in the same anatomical location (e.g., subcutaneous pocket). The monitoring device may include a telemetry unit that transmits physiological measurement data to a local data collection system (e.g., carried by the patient or located in the patient'"'"'s home), which may re-transmit the data to a remote data collection system (e.g., located at a physician'"'"'s office or clinic) via a suitable communication link.
