Multipolar cardiac catheter for high-density mapping of the left atrium for the treatment of atrial fibrillation (CeraMap)

Project description 

In the CeraMap research project, a cardiac catheter demonstrator was developed with which the misdirected electrical impulses in atrial fibrillation (AFIB) can be detected quickly and cost-effectively using high-density mapping. With conventional catheters, the measurement signals are guided via leads to the proximal end of the catheter. If high-density mapping is the aim, the large number of electrodes required in the space-limited catheter shaft leads to bottlenecks and also causes high material and set-up costs. To overcome these limitations, flexible PCB technology was used in the project. The PCBs were used both for generating the measurement structure and for signal transmission.
