Research Activities in Balloon Angioplasty

The NRC research group in balloon angioplasty develop leading edge technologies for the balloon angioplasty intervention and the design of related cardiovascular devices.

Overview

Innovative tools are being developed to:

• optimise balloon/stent materials and design

• assist the cardiologist in planning the intervention

in order to address the following needs:

• control balloon failure

• balloon/stent miniaturization

• control restenosis and avoid thrombosis

Balloon failure modes

The benefits of membership are:

• competitive advantage on developed technologies

• seminars and web-site access on results of research program

• access to NRC laboratories for prototyping and R&D studies

Research Program
