Medical devices having full or partial polymer coatings and their methods of manufacture

Abstract

Medical devices for insertion into the body of human or veterinary patients, wherein the device comprises a) a working element (e.g. a wire, a guidewire, a tube, a catheter, a cannula, a scope (e.g., rigid or flexible endoscope, laparoscope, sigmoidoscope, cystoscope, etc.) a probe, an apparatus for collecting information from a location within the body (e.g., an electrode, sensor, camera, scope, sample withdrawal apparatus, biopsy or tissue sampling device, etc.) which has an outer surface and b) a continuous or non-continuous coating on the outer surface of the working element. The outer surface of the working element is prepared to create a surface topography which promotes mechanical or frictional engagement of the coating to the working element. In some embodiments the coating is a lubricious coating and/or a swellable coating.
