1. Medical monitoring apparatus comprising:
- (a) support means adapted to be chronically implanted at a predetermined location in the vascular system of a living animal;
(b) means affixed to the support means for sensing at least one measurable parameter; and
(c) means on the support means for telemetrically transmitting signals representative of the sensed parameter percutaneously to a signal receiver.

Abstract
A medical monitoring apparatus designed to be implanted in the vascular system is capable of sensing and transmitting via a telemetry link to an external monitor both pressure and temperature information. An internally or externally powered microcircuit component is supported on a stent-like structure and adapted to be placed in the vascular system. Placement in the ventricular septum permits measurement of pressure and temperature in the left ventricle without introducing thrombus generating materials in the left ventricle.
