    摘要: An intracorporeal device, preferably a guidewire, and method of making same that has an elongate inner core element with an outer layer of material disposed about the core element. The layer of material can be applied as a braid, strand or smooth layer of material, and is preferably a metal. If the layer of material is applied as a braid or strand, it may be subsequently cold drawn so as to create a smooth layer from the braid or strand. The inner core element, may be homogeneous, or may consist of drawn filled tubing with at least two layers of material, preferably biocompatible metals. In this way, the multiple layer distal section of the elongate core can be shaped or ground so as to achieve the desired mechanical properties and provide surfaces for attachment of components that are readily bonded or soldered to.

    摘要: An intraluminal device having an adhesive primer coat formed of a carbonaceous material and a lubricious top coat of a hydrophilic polymeric material. The invention also comprises the methods of making such intraluminal devices. The primer coat of the invention may comprise pure carbon, or a carbon based material such as a polymer. Preferably, the primer coat has a thickness of about 0.1 to about 2 &mgr;m. In a presently preferred embodiment, the primer coat is applied using chemical vapor deposition (CVD), but in certain embodiments, physical vapor deposition (PVD) may be suitable. The deposited primer coat forms an effective substrate for adhesion of the hydrophilic polymer top coat.
