Claim:
1. A method of separating tissue surrounding a lead within a blood vessel, the method comprising the steps of: inserting a sheath set over a proximal end the lead within the blood vessel, the sheath set comprising: aligning the first indicator of the inner sheath with the proximal end of the outer sheath; aligning the rotational position indicator of the inner sheath with the rotational position indicator of the outer sheath, thereby creating a linearly aligned position for the inner sheath and outer sheath; advancing the inner sheath and the outer sheath concurrently in the linearly aligned position over the lead in the blood vessel; and further advancing and rotating the inner sheath such that the first beveled end of the inner sheath extends distally of the beveled distal end of the outer sheath.
