  • Dual outside diameter cannula for insertion into bone
    Publication number: 20030236506
    Abstract: A cannula and a method of inserting the cannula into a bone within a patient. The cannula comprises a distal section, a proximal section, and an intermediate section positioned therebetween. The distal section has a smaller diameter than the proximal section. The smaller diameter assists in inserting the distal section into the bone. The increased diameter of the proximal section gives rigidity and strength to prevent bending or flexing during insertion. The proximal section has a wall thickness greater than the distal section to give rigidity and strength to the cannula.
