Description of Invention

Left Ventricular Assist Devices (LVADs) are a promising alternative to cardiac transplantation in patients in patients with end stage heart failure. These devices are implanted as a bridge to transplant, bridge to recovery and as a destination therapy. The potential of cardiac recovery after using such mechanical support is the most desired goal in the treatment of end-stage heart failure with LVADs, allowing device explantation and avoiding cardiac transplantation and lifelong mechanical support, with reduced complications. There is a critical need for a device for effectively transitioning a patient from having a LVAD to cardiac recovery without complications and unnecessary strain on the heart tissue. 

This invention is a titanium plug for an explanted Left Ventricular Assist Device (LVAD) that is coupled to a suture ring attached to the apex of the left ventricle of a patient’s heart to prevent blood loss from the left ventricle upon removal of the LVAD from the suture ring.

Stage of Development

Prototype with proof-of concept data. The device was approved by FDA for compassionate use for a heart failure patient.
