Abstract
A peel-away sheath for a catheter includes at least one weakened area in a non-longitudinal pattern, such as a helical pattern, along the length of the sheath. One embodiment of a catheter sheath includes a tube having at least one pull wire integrally located within its wall. Another embodiment of a catheter sheath includes a tube having at least one integral lumen within its wall. The integral lumen may house a filling material. One embodiment of a catheter may include a first sheath which is positioned within a second sheath, with each of the first and second sheaths having at least one weakened area along its length. A reinforcing guide for a guide catheter includes a tube having a lumen with a diameter at least as large as the guide catheter diameter. The reinforcing guide includes a gap with a width which is less than the guide catheter diameter.
