Dual lumen peel-away sheath introducer
First Claim
1. An apparatus for introducing at least two medical devices within vasculature, comprising:
- an elongate inner member, the elongate inner member having a length and including structure to separate the at least two medical devices substantially the length of the elongate inner member; and
an introducer sheath having an internal bore sized to receive the elongate inner member;
wherein the elongate inner member and introducer sheath cooperate to receive the at least two medical devices.

Abstract
A system and method for introducing medical devices within vasculature that incorporates a dual lumen introducer allowing a plurality of guidewires to be introduced without entanglement. The introducer further includes slits formed in the dual lumen introducer and a dilator or an inner member with grooves that facilitate easy removal of the introducer and dilator from vasculature. The dual lumen introducer maintains separation between guidewires. The slits in the dual lumen introducer and the dilator grooves allow removal from the guidewires by slipping the device off the guidewires without retracting them the entire guidewire length. A peel-away sheath protects the vasculature from the guidewires, prevents the dilator from slipping off the guidewires, and maintains access to an expanded vessel for the introduction of medical devices.

20. A method for providing a path to a target site within a vessel using an introducer sheath assembly having a length and including structure that receives a plurality of medical devices and that separates the medical devices substantially the length of the introducer sheath assembly, comprising:
-
gaining access to a femoral artery of a patient;
inserting the introducer sheath assembly within the femoral artery;
advancing the introducer sheath so that a distal end thereof is adjacent a bifurcation in an aorta; and
configuring the plurality of medical devices so that the introducer sheath assembly separates the medical devices substantially the length of the introducer sheath assembly. - View Dependent Claims (21, 22, 23)
