Abstract
Methods of using a catheter involve providing a sheath comprising a proximal region, a deflection region, a distal-end region including a shapeable region, an anchor region defined between the deflection region and the shapeable region, and a longitudinal axis. The method also involves imparting a pre-established shape to the shapeable region. The method further involves applying axial force in a proximal direction at the anchor region so as to cause the deflection region to deflect relative to the longitudinal axis while the pre-established shape imparted to the shapeable region of the sheath is substantially maintained.
