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.

Abstract: A method and device for inserting an implant of synthetic material or healthy bone or cartilage into a bone or cartilage defect of unknown depth. The device includes an inner shaft within a hollow outer shaft. One end of the inner shaft of the device is suitable for inserting into the bone or cartilage defect in order to determine the depth, while the other end of the outer shaft is suitable for holding an implant. The implant is cut to fit the defect. The device is partially transparent or translucent to allow visualizing of the implant and defect. The delivery device can be bent or curved to allow the device to be introduced to a defect at different angles and positions. The methods and devices are suitable for delivery of implants to defects having complex shapes.
