Abstract: A kit for connecting a hollow cannula (40) to a hollow organ of a patient's body may include a sheath (70) having a tapered surface defined by a plurality of flaps (92) at its distal end (96). A delivery tube (50) is slidably positioned within the sheath so that the sheath and delivery tube form a sealed enclosure that entirely contains the cannula. The enclosure and the cannula may be completely purged of air. An elongated dilator (10) may project through the sealed assembly in slideable engagement with the sheath and delivery tube. After advancing the liquid-filled enclosure into the organ, the distal end of the sheath is opened by advancing the delivery tube, and the cannula is advanced until an anchor (48) at the distal end of the cannula exits the delivery tube inside the organ and opens to anchor the cannula in place. An external securement device (130) may be applied on the cannula so as to hold the wall of the organ between the expanded anchor on the inside of the wall and the external securement device on the outside of the wall.

Abstract: The present invention relates to an apparatus and methods for pumping blood from the venae cavae to the pulmonary arteries and thereby bypassing the right ventricle of the heart. The apparatus includes a pump and an inflow and outflow cannula. In one embodiment, the inflow and outflow cannula are inserted through a single percutaneous opening into a subclavian vein and advanced into the venae cavae. When the outflow cannula is advanced into a pulmonary artery, it is redirected into same. The pump at a proximal end of the bypass apparatus is disposed in a cavity of the body such as near a patient's rib cage. In operation, blood is carried through the inflow cannula from the venae cavae into the pump and then pumped through the outflow cannula into at least one of the right or left pulmonary artery.
