Abstract:
A method for placing an embolic coil into an aneurysm comprising the steps of:providing a delivery catheter having a proximal end and a distal end, a first lumen and a second lumen with a side opening from the second lumen proximal the distal end of the catheter, and a puller wire extending through said first lumen and being fixedly attached to the delivery catheter at a location proximal the distal end of the catheter; introducing the delivery catheter into the vessel of a patient over a guidewire extending through the second lumen to generally align the side opening of the delivery catheter with the aneurysm; withdrawing the guidewire; pulling the proximal end of the puller wire to cause the delivery catheter to deflect at a location proximal to the side opening in said second lumen to thereby cause the side opening to move to a position adjacent to the aneurysm; introducing an embolic coil deployment device into the delivery catheter through the second lumen and through the side opening; delivering an embolic coil into the aneurysm; withdrawing the embolic coil deployment device from the delivery catheter; releasing the proximal end of the puller wire to permit the catheter to straighten; and, thereafter withdrawing the delivery catheter from the vessel of the patient.
