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.

Claims (18)

1. 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 formed completely upon all of said exterior surface of said surrounding wall, said titaniumized surface also completely covering all of said interior surface; 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 being the only surface formed completely on all of said exterior and said interior surface, and said titaniumized surface being composed exclusively of titanium; said titaniumized surface covering said exterior surface being covalent bonded with said exterior surface in a first layer having a thickness substantially being in a range between 20-60 nm; and

maintaining said thickness within said range providing means to maintain a flexibility of the underlying polymeric material.

2. The lumen bearing component of claim 1 wherein said lumen bearing component is a catheter from a group of lumen bearing catheters including Peritoneal Dialysis Catheters, Hemodialysis Catheters, Pleural Drainage Catheters, Peritoneal Drainage Catheters, Biliary Catheters, Urethral Catheters, CV Catheters, Ventricular-Peritoneal Shunts, Ventricular Drainage Catheters, Ascites Shunts, Urinary Catheters, and PICC lines.

3. The lumen bearing component of claim 1 , wherein the lumen bearing component is a catheter.

4. 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 formed completely upon all of said exterior surface of said surrounding wall, said titaniumized surface completely covering all of said interior surface, said titaniumized surface being the only surface formed completely on all of said exterior and said interior surface;

said titaniumized surface being composed exclusively of titanium, 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 covering said exterior surface is covalent bonded with said exterior surface in a first layer, said first layer having a thickness substantially being in a range between 20-60 nm; and

maintaining said thickness within said range providing means to maintain a flexibility of the underlying polymeric material.

5. The lumen bearing component of claim 4 wherein said lumen bearing component is a catheter from a group of lumen bearing catheters including Peritoneal Dialysis Catheters, Hemodialysis Catheters, Pleural Drainage Catheters, Peritoneal Drainage Catheters, Biliary Catheters, Ureteral Catheters, CV Catheters, Ventricular-Peritoneal Shunts, Ventricular Drainage Catheters, Ascites Shunts, Urinary Catheters, and PICC lines.

6. The lumen bearing component of claim 4 , wherein the lumen bearing component is a catheter.

7. 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; and

a titaniumized surface formed completely upon all of said exterior surface of said surrounding wall, said titaniumized surface also completely covering all of said interior surface, said titaniumized surface also completely covering all of said end wall surfaces, 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 being the only surface formed completely on all of said exterior and said interior surface, and said titaniumized surface being composed exclusively of titanium;

wherein said titaniumized surface covering said exterior surface is covalent bonded with said exterior surface, said interior surface and said end surfaces in a first layer, said first layer having a thickness substantially being in a range between 20-60 nm.
