About Us

At Berlin Heart we do everything we can to provide people with heart failure with the best possible care. The aim of our work is to ensure that these patients live well despite their illness.



Ventricular assist devices for patients worldwide

Berlin Heart GmbH develops, produces and markets innovative systems for mechanical circulatory support. With our products EXCOR® Adult and EXCOR® Pediatric, we cover the entire scope of medical indications. We are the only company in the world offering systems that can support patients of every age and size, from newborns all the way to adults.

Our systems are used for left, right* or biventricular (bilateral) circulatory support: EXCOR®, Berlin Heart’s paracorporeal VAD, is virtually unrivaled in the domain of biventricular circulatory support. 

With our world-renowned products, we are one of the industry's market leaders. We aspire to develop pioneering solutions with the highest precision and reliability. Our developments are always geared toward the needs of our customers and the requirements of the market – and will continue to do so in the future.

(*EXCOR® Adult and EXCOR® as RVAD are not FDA approved.)

What defines Berlin Heart

At Berlin Heart we do everything we can to provide people with heart failure with the best possible care. The aim of our work is to ensure that these patients live well despite their illness. These are our guiding principles:



We support our users during the entire VAD therapy: from patient selection and preparation to implantation and postoperative care. Therefore, we provide a top level 24/7 medical and technical support. 


Outstanding quality

Berlin Heart products and services stand for high quality “Made in Germany”. We produce our blood pumps, cannulae and driving units at our headquarters in Berlin-Lankwitz. Regular audits and certification processes prove the quality of our products.



Future orientation

We invest about half of our turnover in research and development projects. Using state-of-the-art technologies and professional expertise, we are constantly working to develop new products as well as develop existing products further. In research groups, we discuss with clinicians how the VAD therapy can be improved.


With our products we support newborns and children, for whom no approved long-term support exists otherwise. Our sense of responsibility towards patients with heart disease is also reflected in our commitment. For example, we support the McDonald's Kinderhilfe and are committed to an open discussion on organ donation.



Milestones in Berlin Heart’s history

CE-Approval of the EXCOR® Venous Cannula

The EXCOR® Venous Cannula enables a standardized implantation of the EXCOR®  VAD to support the sub-pulmonary circulation of patients with venous connection abnormalities (e.g. Fontan circulation). Patients with failing Fontan circulation thus receive a new chance for a donor heart.

CE-Approval of the EXCOR® Graft Cannula

The new EXCOR® Graft Cannula is designed to offer the surgeon more options for cannulation during the implantation of the EXCOR®  system.

Berlin Heart is one of the first companies worldwide whose quality management system was successfully audited according to the new MDR.

Clinical research

European EXCOR® Investigator Group

In April 2015, users of the Berlin Heart system EXCOR® Pediatric founded the European EXCOR® Pediatric Investigator Group (short EEPIG). The group now consists of more than 50 VAD experts from 15 countries. The aim of the research group is to discuss and improve various aspects of pediatric VAD therapy. The biannual EEPIG meetings also provide a platform for the initiation of multicenter studies. A working group formed by the EEPIG deals, for example, with the topic of anticoagulation. A corresponding study, the Thromboembolic RIsk Study (TRIS), is currently in preparation.


Biventricular Heart Failure Research Group

Representatives of various European VAD clinics form the biventricular heart failure research group. At regular meetings, members evaluate approaches for optimal treatment of patients with biventricular heart failure. Within the research group, the prospective study "Successful support of biventricular heart failure patients by new EXCOR® Adult pumps with bileaflet valves" by Schmack et al. emerged.


Research Funding

Biofluid Mechanics Lab at the Charité – Universitätsmedizin Berlin and Berlin Heart GmbH are jointly involved in the project "Research on a pediatric VAD".

The aim of the project is further research for a pediatric VAD, enabling an explicitly tailored therapy in children. This includes, starting from the clinical boundary conditions for children, the design development of both the bearing and the pump, the validation of the concept and the feasibility studies for the system. Final step of the project will be the validation in an in vivo animal model.

The project is co-financed by the European Regional Development Fund (ERDF).


What we stand for

As a medical technology company, we take responsibility not only for the quality of our products, but also for our patients and fellow human beings. Therefore, we are involved in projects that are particularly close to our hearts:


Ronald McDonald House Charities

With its houses, the foundation offers families of seriously ill children a home near the clinic where the young patients are being treated. As we know how important family closeness is, especially for young patients, we support the foundation and in particular the Ronald McDonald House in Berlin-Wedding. As an annual Christmas donation Berlin Heart assumes the sponsorship for an apartment and therefore its maintenance costs. In addition, our employees get involved in a very personal way: amongst others with renovation campaigns, cooking evenings for the residents of the house or through specially arranged bake sales.


Organ donation

Organ donation: While the number of patients on the waiting lists is steadily increasing, the number of available organs has been declining for years. At Berlin Heart we know what the often long wait for a donor heart means for the patients. This is why we want to draw attention to this problem all the more. Within and outside of our company, Berlin Heart is therefore committed to an open and conscious debate on the issue of organ donation.


Labdoo: This charitable aid project gives children and young people access to IT and education. Berlin Heart supports Labdoo by donating PCs and laptops. The equipment benefits young people in schools, orphanages, child, youth and refugee projects in 107 countries worldwide. The hardware and Labdoo-added software allow pupils and refugees to take full advantage of the digital opportunities.
