1. A bi-directional perfusion cannula, comprising:
an elongate tube configured for insertion into an artery, the elongate tube defining a lumen and including:
a distal region having a first longitudinal axis and extending proximally from a distal tip, the distal tip defining a first aperture in fluid communication with the lumen;
a proximal region having a second longitudinal axis and extending proximally from the distal region to a proximal end;
a bend region disposed between the distal region and the proximal region, the bend region forming an angle such that the first longitudinal axis is non-parallel to the second longitudinal axis; and
a protuberance formed in the elongate tube and formed at least partially on the bend region, the protuberance defining a single length of greater wall thickness compared to a wall thickness of the elongate tube extending proximally and distally therefrom, wherein the protuberance is limited to a lower one half of a cross-section of the elongate tube, wherein a second aperture extends through the protuberance and is in fluid communication with the lumen, the second aperture being centered around a third longitudinal axis different from the first longitudinal axis.
