Patent ID: 7842025

Claim:
A catheter comprising: an elongated, flexible catheter body having proximal and distal ends and a lumen extending therethrough; an intermediate section at the distal end of the catheter body having proximal and distal ends and first and second off-axis lumens extending therethrough; a handle mounted at the proximal end of the catheter body, the handle comprising: a handle housing having proximal and distal ends and generally hollow interior, whereby the catheter body is attached to the handle housing, a first moveable member having a proximal end mounted in the interior of the handle housing and a distal end extending outside the handle housing, the first moveable member being longitudinally moveable relative to the handle housing, and a second moveable member mounted in the interior of the handle housing and longitudinally moveable relative to the handle housing; and a rotatable member mounted on the handle housing, whereby rotation of the rotatable member causes longitudinal movement of the second moveable member; a first puller wire extending through the catheter body and first off-axis lumen of the intermediate section, having a proximal end anchored to the first moveable member of the handle, and having a distal end anchored at or near the distal end of the catheter; and a second puller wire extending through the catheter body and second off-axis lumen of the intermediate section, having a proximal end anchored to the second moveable member of the handle, and having a distal end anchored at or near the distal end of the catheter.
