Abstract
A catheter for sensing vertebrate conditions has plural piezoresistive sensors directly electrically coupled to discrete application specific integrated circuits. A mechano-responsive element is in pressure sensitive relationship with the piezoresistive sensor to act as a transfer medium through which vertebrate conditions such as pressure, temperature, water, glucose, and pH are transferred. Each integrated circuit is electrically coupled to a data acquisition system with monolithic circuitry in order to amplify and multiplex signals from multiple sensors.
