Abstract
Hypotubes such as micromachined hypotubes can include one or more tie layers appropriate for subsequent application of a hydrophilic coating. In particular, a medical device may include a micromachined hypotube having a level of flexibility and a tie layer disposed over the hypotube such that the medical device has a level of flexibility at least substantially equivalent to the level of flexibility of the hypotube.
Claims11
A medical device comprising:
- a hypotube micromachined to include a plurality of slots along substantially the entire length thereof wherein the slots are substantially perpendicular to the axial direction of the hypotube with adjacent slots having distal ends that are substantially semicircular in shape and project in opposite directions along a circumference of the hypotube, the hypotube having a level of flexibility;
- and
- a tie layer disposed about the entire length of the exterior of the hypotube such that the medical device has a level of flexibility at least substantially equivalent to the level of flexibility of the hypotube.
