Abstract
A novel self-blunting needle apparatus (10d) employs a blunting member (70) and a needle (12). The blunting member (70) may be disposed within the needle (12) and may be adapted for fluid flow therethrough. The needle (12) may then be inserted into a patient's tissue and the blunting member (70) may be extended to blunt the apparatus. In other embodiments, e.g., apparatus (10), a driver (76) may be employed to move the blunting member (70) without obstructing fluid flow. There may be a locking spline (58) and cam channel (30) configuration to prevent backward motion of the blunting member (70) in various embodiments. A hollow body (22) is configured to facilitate assembly.
