The summary describes a customized implant based on CT scans and a design process, but there is no mention of AI or ML being used in the design or manufacturing process. The software mentioned is for design and is unchanged from a previous clearance.
No
The device is intended for augmentation or restoration of bony contour, which is a structural or reconstructive purpose, not directly therapeutic in nature like treating a disease or condition.
No
The device is an implant used for augmentation or restoration of bony contour, not for diagnosing a condition.
No
The device description explicitly states the device is a physical implant molded from porous high density polyethylene (HDPE), which is a hardware component. While software is used in the design process, the final device is a physical implant.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "augmentation or restoration of bony contour in craniofacial defects." This describes a surgical implant used directly on the patient's body to correct a physical defect.
- Device Description: The device is a customized implant made of porous material, designed to be fixed into place surgically. It is provided sterile for single use. This is consistent with a surgical implant.
- Lack of IVD Characteristics: An IVD is a medical device intended to be used in vitro (outside the body) to examine specimens, including blood, tissue, and urine, from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not perform any such analysis of biological specimens.
Therefore, the Stryker CMF MEDPOR® Customized Implant is a surgical implant, not an IVD.

III. PREDICATE DEVICE
Stryker CMF MEDPOR Customized Implant – K121315 This predicate has not been subject to a design-related recall.
IV. DEVICE DESCRIPTION
The Stryker CMF MEDPOR® Customized Implant is sold as a kit of two identical implants plus one host bone model. The Stryker CMF MEDPOR Customized Implants are molded from porous high density polyethylene (HDPE) to the specific reconstruction boundaries indicated by the surgeon via submission of CT scans and a customized implant request. The porous structure of the MEDPOR material allows for tissue ingrowth. The implant is fixed into place using compatible Stryker fixation systems. The implants and host bone model are provided sterile for single use only.

Proposed Modification: The Subject device Stryker CMF MEDPOR Customized Implant has the same Intended Use/Indications for use, material, and operational principle as the Primary predicate Stryker CMF MEDPOR Customized Implant K121315. This 510(k) is being submitted to allow for two additional surgeon design options.
V. INDICATIONS FOR USE
The Stryker CMF MEDPOR Customized Implant is intended for the augmentation or restoration of bony contour in craniofacial defects.
The proposed modifications do not alter the Intended Use/Indications for Use statement for the Subject device. The Intended Use/Indications for Use is identical to the Primary predicate device Stryker CMF MEDPOR Customized Implant K121315.
COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE VI. PREDICATE DEVICE
The Stryker CMF MEDPOR Customized Implant is compared to its predicate device for substantial equivalence based on the following criteria:
- A. Principle of Operation
- B. Technological Characteristics
A. Principle of Operation
The basic operational principle of the Stryker CMF MEDPOR Customized implant remains the same: to augment or restore bony contours in the craniofacial region. The Subject device allows for fixation with previously cleared Stryker screws with the addition of plates from the same previously cleared Stryker product line. Both the Subject device and the Predicate device can be trimmed and contoured to fit the specific needs of the patient. The Subject device and the Predicate device are permanent implants and have the same craniofacial area of application.
B. Technological and Operational Characteristics
The Subject device and Predicate devices are based on the following technological elements:
- Same operating principle: to augment or restore bony contours in the craniofacial region
- Same area of contact and contact duration (tissue/bone/greater than 30 days) -
- -Same sizes as the Primary predicate device
- -Same material: there is no change in the implant or host bone material
- Same sterilization method: there is no change in the implant or host bone sterilization method
5
- Similar design process: the proposed modification allows for additional design options compared to the Primary predicate. The surgeon may now choose a nonflanged inlay implant and provide additional "single stage" design inputs for the scope of the implant reconstruction boundary.
- -Similar mode of fixation: screw fixation with the addition of plate fixation
VII. PERFORMANCE DATA
Based on the Risk Analysis performed on the modifications to the device, the following performance data were provided in support of the substantial equivalence determination.
Biocompatibility Testing
Biocompatibility testing was not required as a basis for substantial equivalence. There is no change in the material, duration or location of contact or sterilization method.
Performance Bench Testing
The following performance bench tests were completed.
- -Screw Pullout Testing
- End user validation testing -
Software Verification and Validation Testing
The Stryker CMF MEDPOR Customized Implant does not directly contain software or have an electronic user interface.
Software is used in the design process of the Stryker CMF MEDPOR Customized Implant. The addition of the single stage design option does not change the manufacturing process. The same internal control systems as cleared in the predicate K121315 remain unchanged.
Animal Testing
Animal testing was not required as a basis for substantial equivalence.
Clinical Testing
Clinical testing was not required as a basis for substantial equivalence.
VIII. CONCLUSIONS
The results of the non-clinical data demonstrate the Stryker CMF MEDPOR Customized Implant will perform as intended in the specified use conditions. According to the comparison based on the requirements of 21 CFR 807.87 and the information provided herein, it is concluded that the information included in this submission supports substantial equivalence.
