Abstract
A guiding catheter has incorporated toward its distal end, a flexible member capable of non-uniform elongation to cause the distal end portion to bend and straighten as desired so that it can be maneuvered through and accurately positioned in a tortuous, non-linear conduit containing branches, for example blood vessels. The flexible member comprises interconnected, and preferably braided, filaments with gaps between the filaments. The member has a first configuration that is axially lengthened and a second configuration that is axially shortened. Means are provided to move the member between its first and second configurations. Biasing means are provided to restrict axial lengthening along one side of the flexible member resulting in bending of the catheter tip.
