An implantable or insertable therapeutic agent delivery device |
| abstract |
Disclosed herein is an implantable or insertable therapeutic agent delivery device comprising a coating material provided on at least a portion of said device, said coating material prohibiting substantial release therefrom of a therapeutic agent at or below about a physiological pH and allowing substantial release therefrom of a therapeutic agent at or above about said phxiological pH. Also disclosed herein are coating materials for the implantable or insertable therapeutic agent delivery device. The coating materials are preferably polymers derivatized to contain moieties that are cationically charged at a pH below their pKa values and which thus can attract negatively charged therapeutically agents at pH values below their pKa values and which become predominantly uncharged at pH values above about their pKa values and thus substantially release the negatively charged therapeutic agents at such pH values, which are preferably about physiological pH. Also disclosed are methods of derivatizing a polymer to contain such moieties and methods of providing a coating of the derivatized polymer onto at least a portion of a surface of an implantable or insertable therapeutic agent delivery device. |
