Intended Use

SurgiCase Guides are intended to be used as surgical tools to transfer a pre-operative plan to the surgery. The devices are intended to guide the marking of bone and/or guide surgical instruments during craniofacial osteotomies. SurgiCase Guides are intended for single use only.

Device Story

Patient-specific templates designed from pre-operative software planning (SurgiCase software, K073449) based on CT or MRI imaging; used to transfer surgical plans to physical anatomy. Guides consist of polyamide base shaped to patient anatomy with integrated functional elements for drilling or bone cutting. Used in clinical settings by surgeons during craniofacial osteotomies to improve accuracy of bone marking and instrument positioning. Single-use device; provides anatomical reference for surgical site. Benefits include increased precision in transferring complex pre-operative plans to the surgical field.

Clinical Evidence

No clinical testing was performed. Evidence consists of bench testing, including quantitative validation using bone models and cadaveric specimens to assess accuracy of surgical plan transfer, qualitative fit/stability evaluation, biocompatibility testing, sterilization dimensional stability testing, and packaging/shipment testing.

Technological Characteristics

Patient-specific templates; material: polyamide; sensing/actuation: mechanical anatomical fit; energy source: none (manual); form factor: custom-designed to patient anatomy; connectivity: none; sterilization: validated sterilization cycles.

Indications for Use

Indicated for use as surgical tools to transfer pre-operative plans to surgery by guiding bone marking and/or surgical instruments during craniofacial osteotomies. Intended for single use.

Regulatory Classification

## Device Information

### Description and functioning of the device

The SurgiCase Guides are patient specific devices or templates that are based on a pre-operative software planning and are designed to fit a specific patient. These templates are used to assist a surgeon in transferring this pre-operative plan to the surgery by guiding the marking of bone and/or guiding surgical instruments. Guides are individually designed and manufactured for each patient using a design and manufacturing process with strict procedures and work instructions to guarantee templates that consistently perform in a safe and effective way.

The SurgiCase Guides are based on a software planning generated using the previously cleared SurgiCase software (K073449).

Image /page/1/Picture/0 description: The image shows handwritten text on a white background. The text "K111558" is on the top line, and "P.2 of 3" is on the bottom line. The handwriting is clear and legible, and the text is centered on the page.

SurgiCase is software for pre-operative simulation of implant placement and surgical treatment options, based on imaging information from a medical scanner such as a CT scanner or a Magnetic Resonance Imaging (MRI) scanner. The SurgiCase software was previously reviewed under K073449 and is not submitted for review in this 510k submission. References to the software are included to give a complete overview on the guide design process.

#### Intended use

SurgiCase Guides are intended to be used as surgical tools to transfer a pre-operative plan to the surgery. The devices are intended to guide the marking of bone and/or guide surgical instruments during craniofacial osteotomies.

The principal difference between the subject and predicate device is with respect to the anatomical region where the guides will be applied -- craniofacial for the subject guides versus mandibular and maxillary for the predicate guides.

SurgiCase Guides are intended for single use only.

### Summary of technological characteristics

Device comparison showed that the proposed device is substantially equivalent in intended use, material and performance characteristics to the predicate device.

The proposed device has the same principles of operation as the predicate device: Each guide, made from polyamide, consists of a basic shape that fits the patient's anatomy and serves as an anatomical reference to position the guide on the surgical site. For each planned drill location, a functional element for drilling is added to the base shape and for each planned bone cut, a functional element for cutting is added.

## Performance data

#### Non-clinical tests

Non-clinical tests included to assess the safety and effectiveness of the device:

- . Quantitative validation using bone models and cadaveric specimens to validate the accuracy the guides obtain in transferring a surgical planning to the actual surgery during craniofacial osteotomies. Qualitative validation to evaluate the fit and stability of the guides.
The guides meet the predefined acceptance criteria.

- Biocompatibility testing: According to the results of biocompatibility testing on the finished device, the biocompatibility requirements have been met. Cytotoxicity testing was also performed on the finished device after sterilization. The finished product was determined to be non-cytotoxic.
- Sterility testing: A sterilization dimensional stability test was performed to verify the device does not deform more than the predefined production tolerance after two sterilization cycles. A sterility test demonstrates that the device can be successfully sterilized with the recommended sterilization parameters.
- . A packaging and shipment test was performed to demonstrate the device can be safely shipped without

Conclusion: Testing verified that the accuracy and performance of the system is adequate to perform as intended.

The text appears to be handwritten, with the exception of the words "Clinical tests", which are printed in a bold font. The text is arranged in three lines, with the first line containing the code "K111558", the second line containing the page number "p. 3 of 3", and the third line containing the words "Clinical tests".

No clinical testing was performed to support this submission.

### Substantial equivalence to predicate devices

In conclusion, the SurgiCase Guides have similar intended use, principles of operation and performance characteristics compared to the predicate device. The only difference in intended use is the surgical region where the guides will be applied: cranial for the subject guides versus mandibular and maxillary for the predicate device.

Non-clinical testing data demonstrates that the accuracy and performance of the system is adequate to perform as intended during craniofacial osteotomies. The information presented supports substantial equivalence of these SurgiCase Guides to the predicate device for this new indication.
