Anterior spinal plate with preformed drug-eluting device affixed thereto
First Claim
1. A drug-eluting device comprising a drug-eluting biocompatible matrix comprising a layer of a bioresorbable polymer and at least one antibacterial elutable drug comprising clindamycin at a level of from 1 to about 20 weight percent of the drug-eluting biocompatible matrix in combination with rifampin at a level of from 1 to about 20 weight percent of the drug-eluting biocompatible matrix, and minocycline at a level of from 1 to about 20 weight percent of the drug-eluting biocompatible matrix, said device comprising at least one locking element configured to attach with an anterior spinal plate, wherein the matrix comprises a non-bioresorbable layer disposed in between the plate and the bioresorbable layer and each layer comprises distinct zones of concentration within the matrix with the drugs clindamycin, rifampin and minocycline.

14. A spinal implant kit comprising:
- a) an anterior spinal plate; and
, b) at least one preformed drug-eluting device fabricated from a drug-eluting matrix comprising a layer of a bioresorbable polymer and at least one antibacterial elutable drug comprising clindamycin at a level of from 1 to about 20 weight percent of the drug-eluting matrix in combination with rifampin at a level of from 1 to about 20 weight percent of the drug-eluting matrix, and minocycline at a level of from 1 to about 20 weight percent of the drug-eluting biocompatible matrix, said device comprising at least one locking element configured to attach with said anterior spinal plate, wherein the matrix comprises a non-bioresorbable layer disposed in between the plate and the bioresorbable layer and each layer comprises distinct zones of concentration within the matrix with the drugs clindamycin, rifampin and minocycline.
- a) an anterior spinal plate; and
- 15. A method for surgically installing an anterior spinal plate in a body which comprises surgically installing an anterior spinal plate in the body of a patient and affixing to at least a portion of a surface of the plate at least one preformed drug-eluting device fabricated from a drug-eluting biocompatible matrix comprising a layer of a bioresorbable polymer and at least one antibacterial elutable drug comprising clindamycin at a level of from 1 to about 20 weight percent of the drug-eluting biocompatible matrix in combination with rifampin at a level of from 1 to about 20 weight percent of the drug-eluting biocompatible matrix, and minocycline at a level of from 1 to about 20 weight percent of the drug-eluting biocompatible matrix, said device comprising at least one locking element configured to attach with said anterior spinal plate, wherein the matrix comprises a non-bioresorbable layer disposed in between the plate and the bioresorbable layer and each layer comprises distinct zones of concentration within the matrix with the drugs clindamycin, rifampin and minocycline, the affixing step being carried out prior to, during or following the installing step.
