No
The description focuses on receiving and displaying a numerical signal representing force, with no mention of algorithms, learning, or complex data processing beyond a simple conversion.
No
The device aids the surgeon in developing a balanced implantation by displaying force readings but does not directly treat the patient or perform a therapeutic action.
No.
The device aids the surgeon in balancing a knee implantation by displaying force measurements, not by diagnosing a medical condition or disease.
No
The device description clearly states it consists of two physical units: a force sensing unit and an electronic display unit, both of which are battery-powered hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Function: The eLIBRA® system is designed to measure and display force during a surgical procedure (partial knee replacement). It directly interacts with the patient's anatomy during surgery to aid the surgeon in achieving proper balance.
- No Specimen Analysis: The device does not analyze any biological specimens taken from the patient.
Therefore, the eLIBRA® Display Unit and Force Sensor fall under the category of surgical instruments or devices used during a medical procedure, not In Vitro Diagnostics.
N/A
Intended Use / Indications for Use
The eLIBRA® Display Unit is a reusable battery powered device designed to receive an electronic signal from the eLIBRA® Uni Soft-Tissue Force Sensor for a Partial Knee replacement. The unit displays a number from 0-19 for flexion and extension positions of the knee joint to aid the surgeon in developing a balanced implantation during a primary unicondylar knee arthroplasty (UKA). The force sensor is sterile, for single patient use.

Device Description
The device consists of two units, the force sensing unit and an electronic display. The eLIBRA® Uni Soft-Tissue Force Sensor for a Partial Knee Replacement is a single use battery powered device designed to transmit an electronic signal to the eLIBRA™ Display Unit. The eLIBRA Display Unit is a reusable battery powered device designed to receive an electronic signal from the eLIBRA® Uni Force Sensing Unit. The unit displays a number from 0-19 for both the for flexion and extension positions of the knee joint to aid the surgeon in developing a balanced implantation during a primary unicondylar knee arthroplasty (UKA). Each number is equivalent to 0.5 pounds of force.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Both bench and test laboratory testing was performed. Bench testing included mechanical testing, radio frequency, and sterility testing, including EO residues. The results were satisfactory and revealed no concerns over safety and effectiveness as compared to our predicate device. The tests demonstrated that the device is as safe, as effective, and performs in a substantially equivalent manner to the predicate device.
