Abstract

Provided herein is a percutaneous expandable venous cannula device, and related methods. The device is easily inserted, for example, using standard Seldinger technique via the right internal jugular. The device includes multiple, multi-holed limbs that softly fill, e.g., the right atrium to facilitate complete drainage, enable retraction of the chamber in surgery, and mitigate suction occlusion, filling the entire atrium and allowing for efficient and rapid emptying of the chamber. In aspects, the device facilitates minimally-invasive aortic or mitral valve surgery with single placement via the right internal jugular as the sole cannula needed for full support.
