Abstract

The sensor and memory unit (30, 92 or 94) includes a sensor assembly (34) having at least one sensor (48, 50 or 96) therein and a memory (18, 22, 70, 98) associated and fixed therewith. In one embodiment the memory (70, 98) is mounted in a memory module (38 or 90) which is connected by a multiconductor lead (40 or 88) to the sensor or sensors (48, 50 or 96). Also the sensor assembly (34) can be fixed in the distal end (36) of a catheter (32). The sensor and memory unit (94) can be coupled to signal processing and conditioning circuitry (76, 176 or 276) which can include a microprocessor (178) for processing the sensor (96) signals and conditioning/correcting same based upon the information data retrieved from the memory (98).
