Abstract
A long nose manipulatable catheter is described herein. The catheter generally comprises a flexible joint region defining a main lumen and an adjacent wire lumen. The wire lumen has an opening near or at a distal end of the flexible joint region and a push/pull wire can be pushed or pulled through the wire lumen. The catheter assembly may also comprise at least one radio-opaque marker band for securing the push/pull wire. The joint region has a predetermined length sized to affect a flexure of the joint and is generally located at the distal end of the catheter. The joint region itself may be varied to extend distally from where the braid terminates, or it may extend to encompass a portion of the braid. By varying a length of the joint region, the amount of curvature and flexure of the joint region can be controlled.
