4.3.4. CTE Provisional
The Persona Tibial Keel length ranges from 23.4 mm to 40 mm. The Canary Tibial Extension adds
58 mm to the length of the tibial keel nominally when assembled. This CTE Provisional is used to
ensure the fit of the CTE implant within the patient’s anatomy prior to CTE implantation. Figure
7 shows the CTE Provisional.

4.4. Base Station Systems
The CTE with CHIRP Base Station subsystems are composed of external base station units and
associated software that facilitate communication with the CTE implant. There are two Base
Station system configurations: an OR Base Station system for use by the Surgical team, and a
Home Base Station system for use by the Patient. The Base Station units query a specified CTE
implant to transmit data to and from that CTE implant and to the Canary Cloud Data Management
Platform for:
Activation of a CTE implant during surgical procedure
Linking of a CTE implant with a patient
