System and apparatus comprising a multi-sensor catheter for right heart and pulmonary artery catheterization

A control system for a multi-sensor catheter for right heart catheterization and pulmonary artery catheterization, wherein said plurality of optical pressure sensors for measuring blood pressure concurrently at each optical pressure sensor location are configured to measure concurrent pressure waveforms for at least two locations within the right heart and pulmonary artery comprising a right atrial pressure waveform, a right ventricular waveform, a pulmonary artery waveform and a pulmonary capillary wedge pressure, to provide concurrent blood pressure measurements at each optical pressure sensor location, the control system comprising:

• a light source and detector, and an optical interface for coupling, via respective input/output ports, to each of the optical fibers and optical sensors of the multi-sensor catheter;
• data storage and a processor configured for processing optical data indicative of pressure values obtained from each of said optical pressure sensors to generate data for pressure blood pressure waveforms;
• and
• wherein the processor is further configured for outputting said data to a patient monitoring system to display concurrent blood pressure waveforms for at least two of the right atrium, right ventricle and pulmonary artery, and pulmonary capillary wedge pressure.
