Guiding introducer for right atrium
First Claim
1. A guiding introducer to be used in the right atrium of a human heart comprised of a first, second and third sections, wherein a first section is a generally elongated straight section contained in a generally flat plane, wherein merged with the distal end of said first section of said introducer is the second section which is an upwardly curved section curved out of said flat plane in a longitudinal curve from the distal end of the first section with a radius of about 0.5 cm. to about 2.5 cm. to form an arc of approximately 40 to 60 degrees, and wherein merged with the distal end of the second section lies in a plane which is the third section, wherein said third section is directed at an angle of approximately 40 to 60 degrees from the plane of the first section.
