Microelectronic Stent Monitoring
In Germany, approximately 4.5 million people suffer from peripheral arterial vascular occlusive diseases with severe circulatory disorders in the pelvic region and in the legs. Every year there are about 200,000 new cases. These illnesses often result in severe impairments of the patients' quality of life, who often can only walk a few metres without interruption. In order to establish a sufficient blood flow, the patients receive a vascular prosthesis (stent) after reopening of the stenosis, which should keep the affected artery permanently open. Deposits in the stent can lead to flow problems up to complete occlusion with correspondingly serious consequences, ranging from walking difficulties to amputation or death. In order to detect the formation of stenoses at an early stage, the blood flow through the stent must be monitored continuously. Only in this way it is possible to react in time with appropriate medical measures if necessary. This monitoring is currently carried out with the aid of ultrasound procedures, which can only be carried out in appropriately equipped laboratories, which is why continuous monitoring is currently not possible.

The aim of the project is therefore to develop an electronic invasive system that can be inserted into the diseased blood vessels in order to measure the blood flow and telemetrically transfer it to the outside.
