Abstract
A precurved cardiac introducer sheath (4) includes an elongate, hollow body having main and tip portions (24, 22). The tip portion includes first through fifth segments (26, 28, 30, 32, 34). The first, second, and third segments lie in a first plane (36) while the fourth and fifth segments lie in a second plane (38) oriented at a second angle (37) of about .+-.10 to 170.degree. to the first plane. The second segment defines an arc extending along a first, included angle of about 90-110.degree. while the fourth segment defines an arc extending along a third, included angle of about 90-140.degree. . The first, third, and fifth segments are preferably generally straight segments. The precurved introducer sheath is preferably configured to direct the electrophysiology catheter (18) directly at the posterior region (52) of the left atrium (40). The precurved introducer sheath is preferably housed within an outer introducer sheath (46) having a radially deflectable distal end (46), or a fixed distal curve.
