Method and device for selective addition of a bioactive agent to a multi-phase implant
First Claim
1. An implant assembly for constructing a two-phase implant comprising:
- a. a base comprising;
i. a bottom portion;
ii. a top portion;
iii. a lower implant compartment having a cross-sectional shape, said lower implant compartment extending through said top portion and said bottom portion;
b. a cover secured to said base comprising;
i. an upper portion having an upper implant compartment, wherein the upper implant compartment cross-sectional shape is equivalent to the cross-sectional shape of the lower implant compartment; and
ii. a lower portion having a lower receiving compartment sized to receive the top portion of the base.

Abstract
A method and device for assembling a multi-phase implant for insertion into a patient defect site that spans more than one tissue type. The assembly device comprises a base and cover portion for constructing a two-phase implant separated by a membrane. A repeating intermediate portion that connects the base and cover can be used to construct implants with more than two phases, with each phase separated by a membrane. The invention is also for multi-phase implants, wherein adjacent phases are separated by a membrane. In an embodiment, the implant phases are selectively loaded with a bioactive agent selected to promote tissue repair in the tissue surrounding each phase.
