Hemopump

Hemopump is a medical device used in the field of cardiology to assist the heart in pumping blood. It is a type of ventricular assist device (VAD) that is inserted into the aorta to help increase the flow of blood in patients with heart failure or during heart surgery.

Overview

The Hemopump is a small, catheter-mounted, axial flow pump designed to provide temporary circulatory support. It is inserted into the femoral artery and advanced into the ascending aorta, where it helps to pump blood by rotating at high speeds. The device is typically used in patients undergoing high-risk angioplasty, or in patients with severe heart failure who are awaiting a heart transplant.

Mechanism of Action

The Hemopump works by drawing blood from the left ventricle into the aorta, effectively bypassing the heart's pumping function. This is achieved through the use of a small, rotating impeller that creates a flow of blood from the ventricle into the aorta. The speed of the impeller can be adjusted to control the rate of blood flow.

Indications

The Hemopump is indicated for use in patients with severe, refractory cardiogenic shock or in patients undergoing high-risk percutaneous coronary interventions. It may also be used as a bridge to heart transplantation in patients with end-stage heart failure.

Risks and Complications

As with any medical device, the use of the Hemopump carries certain risks. These may include bleeding, infection, vascular damage, and thromboembolism. In some cases, the device may also cause hemolysis, or the destruction of red blood cells.
