Independently-manufactured drug delivery module and corresponding receptacle in an implantable medical device
First Claim
1. A drug delivery system for an implantable medical device comprising:
- a housing of an implantable component of the medical device having an exterior surface with one or more recesses formed therein; and
a drug-delivery module that retains at least a quasi-solid state and releasably carries at least one drug,wherein the module and housing are physically distinct, and the module and recess are correspondingly dimensioned such that a dimension of the module is sized slightly larger than a corresponding dimension of the recess, thereby securing the module within the recess.

Abstract
A drug delivery system for an implantable medical device and methods for making and using the same. Embodiments include a housing of an implantable component of the medical device and one or more at least quasi-solid drug-delivery modules that retain an at least quasi-solid state if not a solid state. The drug-delivery modules and component housing are physically distinct, and as such, may be manufactured independently of each other. The independently-manufacturable drug delivery modules each carry a drug, while the component housing has an exterior surface with one or more recesses formed therein. Associated module(s) and recess(es) are correspondingly dimensioned so that each module may be securely retained within an associated recess via, for example, an interference fit such as by physical interlocking or by friction fit. When so retained in a housing recess, the drug-delivery module and surrounding exterior surface of the housing form a contiguous component surface.

15. A drug delivery system for an implantable medical device comprising:
-
a housing of an implantable component of the medical device having an exterior surface with one or more recesses formed therein; and a drug-delivery module that retains at least a quasi-solid state and releasably carries at least one drug, wherein the module and housing are physically distinct, and the module and recess are correspondingly dimensioned such that the module may be securely retained within the recess, wherein the recess has a dimension that is slightly larger than the corresponding dimension of the drug delivery module thereby forming a gap in the recess after insertion of the drug-delivery module, the gap providing access to a removal tool to facilitate removal of the module from the recess, and wherein the drug delivery system has an a single drug delivery module per recess.

16. A method for implanting a drug delivery system in connection with an implantable medical device, comprising:
-
obtaining a drug-delivery module that releasably carries at least one drug; producing, independently of the drug-delivery module, a housing for the implantable medical device component, the housing having an exterior surface with at least one recess formed therein, wherein the module(s) and recess(es) are correspondingly configured such that a dimension of the module is sized slightly larger than a corresponding dimension of the recess; and inserting the drug-delivery module into the recess subsequent to the device'"'"'s manufacture such that the module is secured in the recess as a result of the dimension of the module being sized slightly larger that the corresponding dimension of the recess. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A method for implanting a drug delivery system in connection with an implantable medical device, comprising:
-
obtaining a drug-delivery module that releasably carries at least one drug; obtaining a housing for the implantable medical device component, the housing having an exterior surface with at least one recess formed therein, wherein the module(s) and recess(es) are correspondingly configured such that a dimension of the module is sized slightly larger than a corresponding dimension of the recess,; and inserting the drug-delivery module into the recess subsequent to the device'"'"'s manufacture such that the module is secured in the recess as a result of the dimension of the module being sized slightly larger that the corresponding dimension of the recess.
