Abstract
An apparatus and method for curving a catheter after deployment include a catheter having a primary lumen, a secondary lumen, and a resilient fiber contained within the secondary lumen. The resilient fiber and the secondary lumen have corresponding, preformed curve shapes when the catheter is in a straight, unstressed condition. The resilient fiber is slidable within the secondary lumen to create a desired curve shape in the catheter as the curved portion of the resilient fiber slides into an originally straight portion of the secondary lumen. In another embodiment, the preformed curve shape of the resilient fiber is held in a straight condition within a stiff, marker ring segment of the catheter until after the catheter is deployed. Once deployed, the resilient fiber is slid out of the marker ring segment, and the preformed curve shape of the resilient fiber creates a corresponding curve shape in the catheter.
