Abstract: An injection needle including a shaft extending between a hub end, an injection end, and a lumen formed within the shaft. The lumen forms an opening that extends through the shaft from the hub end to the injection end. The injection end includes a bevel having a point and a heel, with the opening formed by the lumen passing through the bevel. Multiple slots may be formed within the shaft close to the injection end and near the bevel. The multiple slots may include a first group on one side of the shaft and a second group on an opposing side of the shaft.
