Flagship project: Development of SWORDCATH®

Venipuncture is part of daily routine in medicine

In medicine, "puncturing" a blood vessel means "piercing" it with a needle, known as a "puncture needle". These needles need to be as small as possible – that is, the diameter must be small enough that the puncture doesn't cause damage. For example, punctures can be performed to administer drugs directly into the patient's bloodstream. 
Puncturing is also the first step when introducing a catheter into a blood vessel. "Catheters" are sterile tubes that can potentially remain within the blood vessel for some time to deliver drugs and other infusions.

In an emergency, for example major blood loss in accident victims, the catheter needs to be as large as possible – that is, it must have a large diameter – in order to deliver large quantities of infusion solution or a life-saving blood transfusion over a short period of time. Smaller catheters can suffice for other applications, such as continuously administering drugs over longer periods of treatment.


In many cases, however, the catheter needs to be inserted into one of the large vessels close to the heart, known as the "central venous" vessels. For example, drugs designed to stabilise the patient's blood pressure and heart rate need to take effect as close as possible to the heart.

The SWORDCATH® has a simple design

Current catheter systems can have negative consequences

Currently, most catheter systems rely on the "Seldinger technique", introduced in 1953. This technique is time-consuming and can have negative consequences. It has to be laboriously learned and practiced before it can be performed safely according to the medical guidelines. Since it requires sterile conditions, a whole array of different components are needed, some of which can only be assembled directly at the patient's bedside. This demands a significant investment of time, personnel and space. The procedure usually requires an assistant.

The SWORDCATH® is designed to make catheter insertion much simpler, safer and more efficient 


The SWORDCATH® is being developed as a catheter systems that conveniently packages all the necessary components together. The system uses a novel, intuitive and easy-to-learn puncturing technique that combines a small puncture needle with a larger catheter.


The SWORDCATH® will make it simple, safe and quick to insert either large or small catheters into blood vessels or anywhere else. A series of tests performed on a simulation dummy has produced promising model results.

As well as saving a considerable amount of time, our goal is to eliminate the need for an assistant when using the SWORDCATH®. From the business perspective, this makes the system particularly attractive for cost-intensive applications, such as in the operating theatre. In addition, the SWORDCATH® will only include a few disposable components that have to be discarded as soon as the catheter is inserted. 


The SWORDCATH® will be able to puncture more than just blood vessels, and might therefore open up new applications, leading to new options for patient care. Its simple and stable design gives it an edge in areas where medical supply chains are challenged, for example in emergency, catastrophe and military applications. 


Millions of catheters are inserted into blood vessels around the world every year, so the SWORDCATH® system targets a very broad market. 


Needless to say, the SWORDCATH® system will comply with all regulatory and legal requirements.

Building a portfolio of catheter systems

We are building a portfolio of catheter systems.


Currently, we are developing the ROBUNÜLE, a particularly robust indwelling venous cannula. Together with our partners, we are also working on improved catheter systems to make patient care simpler, safer and more efficient. In our research, we are mindful of professionally protecting our intellectual property.
