Master Thesis Topic 

Optimization of the thermal response time of a PiCCO Catheter for Advanced Hemodynamic Monitoring 

The PiCCO catheter is a key component of the PiCCO hemodynamic monitoring technology and enables the determination of cardiac output through transpulmonary thermodilution. A temperature sensor (thermistor) integrated into the catheter measures very small blood temperature changes. The speed and consistency of this measurement, commonly expressed as the thermal response time (τ), are critical for measurement accuracy and clinical performance. 

Your Challenge 

In this thesis you will investigate how the thermal response behaviour of the existing PiCCO catheter design can be improved and how variability between catheters can be reduced. The current design includes an integrated sensor located inside the catheter, creating a complex heat transfer system between blood, catheter materials, and sensor components. 

Scope  

• Conduct a literature review on heat transfer mechanisms, sensor technology, and medical sensor design. 

• Analyse the current catheter design and identify key parameters influencing thermal response time. 

• Develop and assess innovative design concepts to reduce τ and improve measurement consistency. 

• Investigate the impact of geometry, materials, sensor positioning, and manufacturing tolerances. 

• Perform simulations (e.g., FEM/CFD) and/or experimental testing to evaluate design alternatives. 

• Use Design of Experiments (DoE) and statistical methods to identify critical parameters. 

• Establish decision criteria considering performance, manufacturability, risk, regulatory impact, and cost. 

• Recommend an optimized design concept and implementation roadmap. 

Expected Outcome 

The thesis should deliver a comprehensive understanding of the factors influencing thermal response performance and provide a data-driven recommendation for future product improvements. The results may directly contribute to the next generation of PiCCO catheter technology.
