Abstract
An intraosseous needle set comprising a cannula is provided. The cannula has a first end, a second end, and a bore configured to receive a sample from a target area. The first end of the cannula is configured to penetrate the target area and has a plurality of teeth. The plurality of teeth may have at least one tooth that comprises a tapered surface. The plurality of teeth may each have a first side and a second side, where a length of the first side is less than a length of the second side. The first and second sides may intersect to define tips that are disposed at an angle between 0 and 30 degrees relative to a longitudinal axis of the cannula, and the first side of a first tooth and the second side of an adjacent tooth may also intersect at an angle between 55 and 80 degrees.
