摘要： A medical guidewire system comprising a first inner member having a first outer diameter, a second intermediate member having a second outer diameter larger than the first outer diameter, and a third outer member having a third diameter larger than the second outer diameter of the second member. The second member has a longitudinal extending opening to receive the first member for sliding movement with respect to the first member and the third outer member has a longitudinally extending opening to receive the second member for sliding movement with respect to the first and second member. The first member has a first stiffness, the third member has a third stiffness greater than the first stiffness, and the second member is movable to stiffen the guidewire system.

摘要： A method of adjusting the stiffness and size of a guidewire without full withdrawal of the guidewire from a patient's vascular system comprising providing a guidewire system comprising an inner member having a first outer diameter and a first stiffness, an outer member having a third larger diameter and a third stiffness, and a stiffener positioned between the inner and outer members and having a second outer diameter larger than the first diameter and smaller than the third diameter. The method includes selectively changing the relative positions of the members to alter the pushability and stiffness of the guidewire system.
