Heart assist device

a heart assist device and heart tube technology, applied in the field of heart assist devices, can solve the problems of affecting the ability of the heart tube to fully unload the ventricle, the risk of bleeding and/or thromboembolic complications, and the vads may also present a risk of complications, so as to reduce the size of the device, prevent the backflow into the ventricle, and enhance the natural flow of blood

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a heart assist device and more particularly, though not necessarily, to an improved implantable left ventricular assist device.

[0002] Background to the Invention

[0003] A ventricular assist device, or VAD, is a mechanical device used to help either one or both ventricles of the heart to pump blood. VADs are designed to assist either the right (RVAD) or left (LVAD) ventricle, or both at once (BVAD). The choice of device depends on the underlying heart condition, although LVADs are the most widely used.

[0004] In early procedures, the VAD pump was placed outside the body. More recently, the most commonly used VADs comprise an integrated pump and are implanted during open or closed-heart surgery, with a control line passing through the skin to a body worn controller. The use of implanted VADs with integrated pumps improves patient mobility and therefore a patient's capacity to lead a near normal life outside hospital.
