The wall also at least partially defines a second lumen extending lengthwise of the wall and terminating in a closed second end. The wall is configured and dimensioned such that the cannula can be inserted into the patient's heart. A first aperture extends through the wall from the first lumen to an exterior surface of the wall. A second aperture extends through the wall from the second lumen to the exterior surface of the wall.Type: ApplicationFiled: February 17, 2023Publication date: August 24, 2023Inventors: Jose L.
