IMPELLA HISTORY:
It could be said that the Impella heart pump catheter is derived from the machine designed by Archimedes in Alexandria, in the 3rd century BC: the Archimedes screw.
This is a summary, detailed and expanded information in this video:
This machine was a positive displacement pump, and not really an axial pump.
Irrigation systems based on Archimedes' screw have persisted in some regions of the world, as Egypt.
In 1976, doctor Richard Wampler, from USA, visited Egypt, and this irrigation mechanism caught his attention.
Returning home, got involved in the design of artif hearts. Using the idea, but with impeller, his team developed the Hemopump. Introduced through femoral artery, powered by external motor, it could provide flow of 3 to 4 L/min.
However, Hemopump failed to success and was discontinued. Fortunately, the principles persisted. In 1991, Siess et al, in Aachen, Germany, initiated modifications to enhance the Hemopump design: redesigned impeller and motor into the catheter itself.
Impella Cardiotechnik was founded in December 1997. This small company developed successful pilot animal experiments with Impella, and obtained CE-label in 1999 for intraoperative use.
Finally, in 2005, after developing diverse products and numerous patents, the company was acquired by the American medical technology firm Abiomed.
