Abstract
A splittable cannula includes a radiopaque marker placed at or near the distal end of the cannula. The radiopaque marker may be a unitary piece, or may consist of several portions. The cannula may include a sheath or catheter body with a grooved score line running along a portion of the sheath body and a radiopaque marker located at a distal end of the body and abutting the body. The radiopaque marker may be located within the lumen of the sheath, may be embedded in the sheath wall, or may be affixed to the external sheath wall. The radiopaque marker may be scored, notched, grooved, or contain apertures longitudinally. The notches, grooves, apertures, and/or score lines in both the sheath or catheter body and the radiopaque marker serve to provide a weakened tear path. An electrode lead may be coupled with the radiopaque marker.
