Patent Application Titled "Packaging For A Ventricular Assist Device" Published Online (USPTO 20240277995).

A patent application titled "Packaging For A Ventricular Assist Device" has been published online. The inventors of the device are Friedland, Ori; Lubinsky, Gad; Rosenblum, Daniel; Rozenfeld, Avi; Troshin, Victor; Tuval, Yosi; Zemer Harel, Hagit. The ventricular assist device is a mechanical circulatory support device used to assist and unload cardiac chambers in patients with a failing heart or at risk during percutaneous coronary interventions. The device includes a motion-cushioning spring that acts as a shock absorber and is coupled to an elastomeric material to reduce the risk of thrombi and hemolysis. The patent application also describes the use of a distal thrust bearing and a proximal motion-cushioning spring to stabilize the impeller of the device. The apparatus is designed to be packaged in a non-radially constrained configuration for delivery to the left ventricle using a delivery catheter. The packaging includes a slanted surface to reduce the likelihood of air bubbles entering the catheter. [Extracted from the article]
