ABSTRACT:
A catheter employs a pre-formed distal end and a proximal deflection mechanism for steering the catheter. A shaped member extends from a shaped region of the catheter sheath to at least a portion of an anchor region. A steering ribbon extends from a proximal region of the sheath and passes within at least a portion of the anchor region. A distal end of the steering ribbon is joined with a proximal portion of the shaped member. At least one steering tendon is disposed within the sheath and has a first end attached at the anchor region and a second end located at the proximal region of the sheath. Movement of the steering tendon in a proximal direction causes the deflection region to deflect relative to the longitudinal axis of the catheter while the shape of shaped region of the sheath is substantially maintained.
