1. Medical monitoring apparatus comprising:
- (a) a tubular stent having first and second ends and a lumen extending therebetween, the first end adapted for placement in a left cardiac chamber with the second end extending through a portion of the cardiac septum into a right cardiac chamber of a living animal;
(b) means on the first and second ends adapted for cooperating with the cardiac septum for inhibiting displacement of the tubular stent;
(c) an occluding member disposed in the lumen;
(d) electronic circuit means affixed to the tubular stent for sensing at least one measurable parameter; and
(e) electronic circuit means on the tubular stent 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.
