Arterial cannula which allows proximal and distal perfusion within a cannulated vessel

A cannula includes a first segment configured to reside entirely within a vessel. The first segment includes a proximal exit opening disposed nearer to the heart, and multiple fenestrations disposed distally away from the proximal exit opening near a cannulation site. The fenestrations in combinatio...

Summary:A cannula includes a first segment configured to reside entirely within a vessel. The first segment includes a proximal exit opening disposed nearer to the heart, and multiple fenestrations disposed distally away from the proximal exit opening near a cannulation site. The fenestrations in combination with the proximal exit opening enable simultaneous perfusion of blood into the cannulated vessel along proximal and distal directions. During a medical procedure, blood introduced into a vessel (e.g., the femoral artery) by way of the cannula can exit the cannula in a manner that provides concurrent blood flow in a first set of directions proximally towards the heart and a second set of directions distally away from the heart. Radially displaceable anchoring elements positionable adjacent to the vessel's superficial wall aid retention of the first segment in the vessel. The fenestrations and/or anchoring elements can be arranged obliquely around portions of the cannula's circumference.
