Patent ID: 8182544

Claim:
A method for placing an embolic agent into an aneurysm comprising the steps of: using a delivery catheter having a proximal section, an intermediate section, and a distal section which is formed from a relatively flexible polymeric material, the delivery catheter having a first lumen and a second lumen, and the delivery catheter having a pre-shaped retaining wire extending through the first lumen to form a normally deflected distal section; inserting a straightening wire into the second lumen of the delivery catheter to cause the normally deflected distal section of the delivery catheter to become relatively straight; introducing the delivery catheter into a vessel of a patient to a position where the normally deflected distal section is generally aligned with an aneurysm; withdrawing the straightening wire from the second lumen of the delivery catheter to cause the normally deflected distal section to again become deflected and thereby move to a position proximate to the aneurysm; introducing an embolic agent deployment system into the second lumen of the delivery catheter and through the normally deflected distal section; delivering an embolic agent into the aneurysm with the embolic agent deployment system; withdrawing the embolic agent deployment system from the delivery catheter; again inserting the straightening wire into the second lumen of the delivery catheter to cause the normally deflected distal section to become relatively straight; and, thereafter withdrawing the delivery catheter from the vessel of the patient.
