    摘要: Medical devices for navigation through anatomy, including guidewires, which may have a core wire, a slotted tubular member, or both. Embodiments may have coils, including non-circular cross-section edge-wound marker coils, extended coil tips, and soldered or glued mesial joint coils. Core wires may have a step, ridge, or taper at the joints to the tubular member, and may be flattened at the distal tip. Radiopaque material may be located inside the tubular member, and the distal tip may be heat treated to make it shapeable. Additional tubular members or coils may be used concentrically or in line and may enhance flexibility, provide radiopacity, reduce friction, or reduce material or manufacturing cost. Tubular members may be chamfered or tapered continuously or incrementally. Slots may be arranged in groups, such as groups of three, and may be equal in depth or unequal in depth to provide a steerable or compressible tip.

    摘要: This is a catheter assembly and a section of that catheter assembly. That catheter assembly may be used in accessing a tissue target within the body, typically a target which is accessible through the vascular system. Central to the invention is the use of a braided metallic reinforcing member, typically of super-elastic alloy ribbon, situated within the catheter body in such a way to create a catheter having an exceptionally thin wall, controlled stiffness, high resistance to kinking, and complete recovery in vivo from kinking situations. The braid may have a single pitch or may vary in pitch along the axis of the catheter or catheter section. The braided ribbon reinforcing member typically is placed between a flexible outer tubing member and an inner tubing member to produce a catheter section which is very flexible but highly kink resistant. The catheter sections made according to this invention may be used alone or in conjunction with other catheter sections either made using the concepts shown herein or made in other ways. The more proximal sections of the catheter assembly are often substantially stiffer than the more distal sections due to the presence of stiff polymeric tubing or metallic tubing or composited materials in the stiffer section.
