CANNULAE AND SYSTEM HAVING REDUCED FLOW RESISTANCE

摘要

A multilumen cannula (1700) is provided for the exchange of blood within a patient's vasculature. The cannula (1700) a multilumen includes a first elongate portion (1702) defining a first lumen (1704) and a second elongate portion (1706) defining a second lumen (1708). The first elongate portion (1702) extends between a first distal end (1710) and a proximal end (1714). The second elongate portion (1706) extends between a second distal end (1712) and the proximal end (1714). At least one of the first elongate portion (1702) or the second elongate portion (1706) is configured to reduce flow resistance through the cannula.
