Wireless Implantable Sensor for Early Detection of Stent Blockages

healthTestedTRL 5

Imagine a tiny, smart alarm system inside a blood vessel. When a stent—which is like a small mesh tube used to keep arteries open—starts to clog up again, this sensor sends a wireless signal. It lets doctors find the problem early and fix it before it leads to serious complications like limb loss.

The business problem

What needed solving

Stents often reclog (restenosis) in 23% of cases, but this is usually detected too late, leading to high mortality and amputations. There is currently no low-cost, frequent, non-invasive way to monitor these implants.

The solution

What was built

A wireless implantable sensor system consisting of an optimized geometric stent design, a read-out unit (ROU) with digital filters, and a diagnostic software algorithm based on NASCET criteria.

Who can put this to work

Medical Device Manufacturing
enterprise
Target: Cardiovascular stent producer

If you are a stent producer dealing with the 23% restenosis rate occurring within 6 years after implantation — this project developed a smart monitoring device that enables early, non-invasive diagnosis. This adds a high-value monitoring layer to existing therapeutic hardware.

Healthcare Providers
mid-size
Target: Angiology and vascular clinics

If you are a clinic dealing with the unmet challenge of frequent PAD surveillance — this project developed a low-cost read-out unit that allows non-specialist practitioners to monitor patients. This reduces the need for expensive, specialized diagnostic equipment for every check-up.

Health Insurance
enterprise
Target: Private health insurance providers

If you are an insurer dealing with the high costs of late-stage PAD complications and amputations — this project developed a wireless detection system that prevents unchecked disease progression. This could save the EU economy over €1bn per year by reducing emergency interventions.

Frequently asked

Quick answers

What is the cost-benefit of this system?

The device is designed for low-cost monitoring by non-specialist practitioners, which is estimated to save the EU economy over €1bn per year.

Can this be scaled for global markets?

Based on available project data, there is a massive global market with over 237 million people suffering from PAD and 3.5M stents implanted annually.

What is the IP or licensing status?

Based on available project data, the project is led by VesselSens GmbH, but specific patent or licensing terms are not detailed in the summary.

What regulations must the device meet?

The project has already carried out biological safety evaluations meeting the requirements of ISO 10993-1:2018.

What is the current development timeline?

The project runs from October 2022 to July 2025, with animal testing (Task 1.4) as the current upcoming milestone.

Consortium

Who built it

The project is managed by a single-partner consortium consisting of VesselSens GmbH, a German SME. This 100% industry-led structure suggests a strong focus on commercialization and rapid market entry rather than academic research, with the SME acting as both the coordinator and the sole developer.
