Better treatment for heart patients

Minimally invasive and gentle: 
Drug-coated balloon catheters

A new medical technology could help millions of heart patients worldwide: Hemoteq, a Freudenberg Medical company, has developed a drug-coated balloon catheter that can keep narrowed heart vessels open over the long term.


Gentle and effective


Coronary heart disease is the leading single cause of death worldwide. Until now, patients often had to be treated with bypass surgery or stents. The new balloon catheter offers a more gentle alternative:

  • Minimally invasive procedure
  • No permanent implants (stents)
  • Fast recovery and lower risks

Precision on a micro scale

The innovation lies in the special coating: its microcrystalline structure ensures that the drug is delivered precisely and in a controlled way where it is needed. 

The balloon is just two millimeters wide and twelve millimeters long – requiring extremely precise manufacturing processes.

Improved quality of life, lower risk


The treatment can be repeated as often as necessary and leads to shorter hospital stays and fewer complications. The balloon catheter is already available in the USA, Europe, and Asia.

Did you know?


Each year, around nine million people die from coronary heart disease due to plaque buildup in the coronary arteries, which restrict blood flow and can lead to heart attacks. Many of these cases could be prevented with timely diagnosis and targeted treatment.
