No
The summary describes a software component for planning and a hardware component for guiding, but there is no mention of AI, ML, or any related technologies in the description or performance studies. The system relies on identifiable anatomical landmarks from imaging scans for alignment and positioning.
No
The device is a surgical instrument designed to assist in the positioning of Total Knee Replacement components and marking bone, not to treat a disease or condition itself.
No
Explanation: The device is described as a surgical instrument system used to assist in the positioning of Total Knee Replacement components, guide bone marking, and aid in implant alignment. Its functions are intra-operative assistance and guidance, not diagnosing a patient's condition.
No
The device description explicitly states that the system consists of both a software component and a hardware component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Device Function: The Zimmer Patient Specific Instruments System is described as a surgical instrument used intra-operatively to assist in the positioning of knee replacement components and guiding bone marking. It uses patient imaging data (MRI) to create patient-specific guides for surgery.
- Lack of Biological Sample Testing: The description does not mention any testing of biological samples from the patient. The system's function is based on anatomical landmarks identified from imaging data and used during the surgical procedure itself.
Therefore, the device's purpose and mechanism of action clearly fall outside the scope of in vitro diagnostics. It is a surgical planning and guidance tool used during a surgical procedure, not a diagnostic test performed on biological samples.

Intended Use / Indications for Use
The Zimmer Patient Specific Instruments System is intended to be used as a surgical instrument to assist in the positioning of Total Knee Replacement components intra-operatively and in guiding the marking of bone before cutting provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans.
The Zimmer Patient Specific Instruments System is to be used with Zimmer NEXGEN CR-FLEX fixed bearing, Zimmer NEXGEN CR fixed bearing, Zimmer NEXGEN LPS-FLEX fixed bearing, Zimmer NEXGEN LPS fixed bearing and Zimmer Gender Solutions Natural - Knee Flex fixed bearing prostheses families only.
The Zimmer Patient Specific Instruments are intended for single use only.

§ 888.3560 Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.

Device Information
Description of the device
The Zimmer Patient Specific Instruments System consists of a software component, Zimmer Patient Specific Instruments Planner and a hardware component, Zimmer Patient Specific Instruments and is designed to assist the surgeon in the placement of total knee replacement components for Zimmer NEXGEN CR-FLEX fixed bearing, Zimmer NEXGEN CR fixed bearing, Zimmer NEXGEN LPS-FLEX fixed bearing, Zimmer NEXGEN LPS fixed bearing and Zimmer Gender Solutions Natural - Knee Flex fixed bearing prostheses.
Functioning of the device
The Zimmer Patient Specific Instruments System generates a pre-surgical plan based on MRI imaging data using the Zimmer Patient Specific Instruments Planner (software component). The software is then used pre-operatively by a qualified surgeon to inspect, fine-tune and approve the pre-surgical plan. Next, Zimmer Patient Specific Instruments are designed and manufactured based on the approved pre-surgical plan. Zimmer Patient Specific Instruments are patient specific templates that transfer the pre-operatively determined positioning of the Total Knee Replacement components to the patient intra-operatively, assisting the surgeon in positioning and aligning the actual Total Knee Replacement components by guiding and marking drill locations.
Intended use
The Zimmer Patient Specific Instruments System is intended to be used as a surgical instrument to assist in the positioning of Total Knee Replacement components intra-operatively and in guiding the marking of bone before cutting provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans.
The Zimmer Patient Specific Instruments System is to be used with Zimmer NEXGEN CR-FLEX fixed bearing, Zimmer NEXGEN CR fixed bearing, Zimmer NEXGEN LPS-FLEX fixed bearing, Zimmer NEXGEN LPS fixed bearing and Zimmer Gender Solutions Natural - Knee Flex fixed bearing prostheses families only.
The Zimmer Patient Specific Instruments are intended for single use only.
