Abstract
A bio-compatible lumen bearing device such as a catheter formed of a polymeric material having a titanium surface bonded to the underlying exposed catheter surface. The titanium surface is employed in patients to improve bio-compatibility and enhance lubricity during insertion and removal.
Claims9
A lumen bearing component comprising:
- a lumen defined by an interior surface of a surrounding wall having an exterior surface and additionally having end wall surfaces communicating between said interior surface and said exterior surface, said lumen formed of polymeric material being flexible as needed for intravenous insertion and navigation;
- a titaniumized surface, said titaniumized surface formed in a first layer completely covering all of said exterior surface of said surrounding wall;
- said titaniumized surface providing means for increased lubricity and bio-compatibility with a body of a patient in which said catheter is positioned;
- said titaniumized surface in said first layer being the only surface formed completely on all of said exterior surface, said titaniumized surface being composed exclusively of titanium;
- a second layer of said titaniumized surface also completely covering all of said interior surface;
- said titaniumized surface covering said exterior surface in said first layer and said titaniumized surface covering said interior surface in said second layer, both having a thickness, said thickness being substantially being in a range between 20-60 nm;
- and
- said thickness of both said first layer and said second layer of said titaniumized surface, within said range, providing means for maintaining a flexibility of the underlying polymeric material.
