Abstract
An inlet cannula is provided for supplying a fluid from a human vessel to a fluid pump, the inlet cannula formed as a hollow structure suitable for conveying the fluid and a surface of the inlet cannula has an ingrowth zone and an inlet zone separated from each other by a tear-off edge extending in the circumferential direction of the inlet cannula, wherein a first tangent to the inlet zone on the tear-off edge has an angle to a longitudinal axis of the inlet cannula of >0° and <180°, and wherein a surface roughness in the ingrowth zone is greater than a surface roughness in the inlet zone, and wherein along the flow direction the ingrowth zone is concave, convex, or not curved and the inlet zone is convexly curved, and wherein the tear-off edge forms a curvature transition between the ingrowth zone and the inlet zone.
