B0410/7118 DBB/tac 0414h SUPERELASTIC FORMABLE GUIDEWIRE Abstract of the Disclosure A guidewire is provided having a malleable segment extending beyond a superelastic tip portion of the guidewire. Such a configuration provides a guidewire which is resistant to kinking and plastic deformation in the superelastic portion, but which has a distal segment which can be shaped by a physician immediately prior to use in a surgical procedure. The malleable segment can be attached to the distal end of the superelastic tip portion, or alternatively, can result from a malleable coating on a portion of the superelastic tip, wherein the coating is thick enough to allow the coated portion of the tip to be formed into a desired shape. The malleable segment can be radiopaque to ease fluoroscopic visualization of the guidewire. In addition, the entire guidewire located proximally to the malleable segment can be fabricated from a superelastic alloy to provide resistance to kinking and plastic deformation along virtually the entire length of the guidewire.
