Abstract
A flexible cannula device includes a solid cannula shaft, a solid cannula tip including an opening, and a coil positioned between and welded to the cannula shaft and cannula tip, the cannula shaft, coil, and cannula tip forming a lumen in fluid communication with the opening. A flexible cannulated drill includes a solid cannula shaft, a solid cannula tip shaped to drill through tissue, a coil positioned between and welded to the cannula shaft and cannula tip, and a handle connected to the cannula shaft. The coil can be a double helix coil comprising an inner coil within an outer coil. A tube inside the coil prevents fluid from leaking between rings of the coil. A cannula system includes an introducer needle and the flexible cannula device. A screw mechanism can adjust a length that the flexible cannula device extends beyond a distal end of the introducer needle.
