Abstract: A medical insertion device includes an introducer assembly, a needle, and a housing. The introducer assembly includes a dilator coaxially disposed in a sheath, the dilator removably engaged to the sheath in an insertion configuration. The needle is coaxially disposed in the dilator, the needle having a distal tip and a proximal end coupled to a needle hub. The housing may be removably engaged to the dilator. The needle hub is movably disposed in the housing between a first locked position, a second locked position, and a third locked position.

Abstract: A CNC system including a travelling drive bar assembly for support of material to be processed. A CNC system including a cutting tool operates on a work piece in at least three axes, with a gantry across the machine that a carriage moves along and a tool that moves vertically on the carriage. A drive bar, oriented perpendicularly to the gantry and to a vertical axis, may travel to support and move the workpiece along its line of orientation. The drive bar may include an elongated structural member, two tracks mounted longitudinally to the elongated member on opposite sides of the elongated member, and a rack, adapted to accept a pinion to urge the drive bar to move, also mounted longitudinally to the elongated member. Guide wheels may receive the tracks to support and align the drive bar. Rollers may further support material that is mounted to the drive bar.
