An obturator device for protecting a needle bevel and facilitating insertion of a needle into an elongate medical tube, such as a drainage catheter, is disclosed. The obturator device includes a jacket that mates and is substantially flush with the needle bevel, and a sleeve that encircles the jacket and needle bevel to protect against piercing or puncturing the medical tube during a medical procedure. The obturator device also includes a mandrel coupled to the jacket and extending outwardly therefrom and into a needle lumen to secure the jacket against the needle. In an example use, the obturator device and needle are advanced through a cavity of the medical tube until the obturator device extends from a distal end of the medical tube. Thereafter, the obturator device is removed to expose the needle bevel on a distal end of the medical tube for insertion into a patient's body.
