First Claim
Patent Images
1. A drug-eluting device comprising:
- an open cell drug-eluting matrix containing at least one elutable drug and at least one anti-adhesion substance that facilitates non-irritating motion of the device across adjacent tissue; and
an anterior spinal plate comprising at least one affixation feature for providing affixation of the drug-eluting matrix to said anterior spinal plate,wherein said drug-eluting matrix is configured to engage a surface of said anterior spinal plate and comprises rifampin and minocycline, wherein the rifampin and minocycline are configured to be eluted from said drug-eluting matrix towards said surface of said anterior spinal plate, andwherein said anterior spinal plate and said drug-eluting matrix are provided as two separately sterilized components, said anterior spinal plate being sterilized using an autoclave and said drug-eluting matrix being sterilized using sterilizing radiation or sterilant gas.
