Patent ID: 7066925

Claim:
A method of inserting a catheter over a catheter guide wire comprising: providing a catheter having: an elongated body having a proximal end and a distal end; a first lumen having: a sidewall extending between the proximal end and the distal end; a first distal opening disposed at the distal end; and a first guide wire opening disposed proximally of the distal end and co-planar with the sidewall; and a second lumen connected to the sidewall and extending between the proximal end and a second distal end, proximal of the distal end, wherein the second lumen includes: a second opening extending obliquely away from the sidewall distally toward the first distal opening; and a second guide wire opening disposed proximally of the second opening and in a plane generally parallel to the sidewall; wherein the method further comprises: providing a catheter guide wire having a proximal end; inserting the proximal end of the guide wire through the first distal opening; inserting the proximal end of the guide wire through the first lumen to the first guide wire opening; exiting the proximal end of the guide wire from the first lumen through the first guide wire opening; pulling the proximal end of the guide wire longitudinally along an exterior of the first lumen to the second lumen; pulling the proximal end of the guide wire over the second lumen to the second guide wire opening; inserting the proximal end of the guide wire through the second guide wire opening and into the second lumen; inserting the proximal end of the guide wire through the second lumen; and drawing the proximal end of the guide wire from the proximal end of the second lumen.
