METHOD AND DEVICE FOR SELECTIVE ADDITION OF A BIOACTIVE AGENT TO A MULTI-PHASE IMPLANT

摘要

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 portion (20) and cover portion (30) for constructing a two-phase implant separated by a membrane (23). A repeating intermediate portion (40) that connects the base (20) and cover (30) can be used to construct implants with more than two phases, with each phase separated by a membrane (23). 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.
