Abstract
A method of manipulating a catheter assembly involves providing an inner catheter member movably disposed within an outer catheter member. At least a distal end portion of the inner catheter member has a stiffness greater than that of at least a distal end portion of the outer catheter member. The distal end portion of the outer catheter member includes a deflectable distal end. The method further involves advancing the inner catheter member through the outer catheter member toward the deflectable distal end of the outer catheter member, and longitudinally displacing the distal end portion of the inner catheter member relative to the deflectable distal end of the outer catheter member to alter a shape of the deflectable distal end.
