Abstract: An expandable stent for medical implantation is described which has a generally cylindrical structure with a central longitudinal axis. At least a portion of the generally cylindrical structure is formed from an arrangement of circumferentially curved structural members. The portion expands from a compressed state to an expanded state by a spiraling motion of each of the structural members about the central longitudinal axis. In the compressed state, each of the structural members may nest within an open region formed by segments composing the structural member, such that the portion of the generally cylindrical structure has no overlapping regions. A ratio of a circumferential length of each structural member to a spacing between adjacent structural members may be in the range of about 1.8 to about 2.3.

Abstract: A bi-directional steerable guidewire having a deflectable distal tip which comprises a longitudinal hypotube and a spring coil attached to the distal end of the hypotube and also includes a longitudinally movable deflection member which is attached to the distal end of the spring coil and a tip retaining member which extends from the distal end of the hypotube to the distal end of the spring coil for providing very precise deflection of the distal tip.
