Intended Use

CenterMed Patient Matched Assisted Surgical Planning (ASP) System is intended for use as a software system and image segmentation system for the transfer of imaging information from a medical scanner such as a CT based system. The input data file is processed by the ASP system and the result is an output data file. This file may then be provided as digital models or used as input to a rapid prototyping portion of the system that produces physical outputs including anatomical models, surgical splints and surgical planning case reports for use in maxillofacial surgery. CenterMed Patient Matched ASP System is also intended as a pre-operative software tool for simulating/evaluating surgical treatment options.

Device Description

CenterMed Patient Matched Assisted Surgical Planning (ASP) System is a combination of software design and additive manufacturing for customized virtual pre-surgical treatment planning in maxillofacial reconstruction and orthognathic surgeries. The system processes patients' imaging data files obtained from the surgeons for treatment planning and outputs various patient-specific products (both physical and digital), including surgical guides, anatomical models, surgical splints, and surgical planning case reports. The physical products (surgical guides, anatomical models and surgical splints) are manufactured with biocompatible polyamide (PA-12) using additive manufacturing (Selective Laser Sintering).

AI/ML Overview

The CenterMed Patient Matched Assisted Surgical Planning (ASP) System is intended for use as a software system and image segmentation system for the transfer of imaging information from a medical scanner (e.g., CT) to produce digital models or physical outputs like anatomical models, surgical guides, surgical splints, and surgical planning case reports for maxillofacial surgery. It also serves as a pre-operative software tool for simulating/evaluating surgical treatment options.

2. Sample Size Used for the Test Set and Data Provenance

The document does not describe a clinical study with a "test set" in the traditional sense of evaluating algorithm performance against ground truth on patient data. Instead, it details non-clinical tests for the physical and software components.

  • Mechanical Testing: Test specimens were used for bending and tensile testing. The specific number of specimens is not provided, but they were sterilized and aged to evaluate material properties.
  • Biocompatibility Testing: Test specimens (presumably of the device materials) were used for cytotoxicity, sensitization, intracutaneous reactivity, acute systemic toxicity, and pyrogenicity tests. The specific number of samples for each test is not detailed.
  • Sterilization Validation: Not specified, but sufficient samples would be used to demonstrate a sterility assurance level of 10^-6^.
  • Software Validation: This involved "Quality and on-site user acceptance testing" based on pre-defined requirement specifications. It does not refer to a data set for algorithm evaluation, but rather to the internal validation of the software development process and functionality.

The data provenance is from internal testing performed by the manufacturer or their designated testing facilities, rather than clinical patient data. The country of origin of the data is not specified directly, but the company is based in Walnut Creek, California, USA, and the tests refer to international standards (ISO, ASTM, USP). The studies were conducted specifically for the purpose of this 510(k) submission (prospective in the context of regulatory filing).

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

Not applicable. This device is not an AI/ML diagnostic or prognostic tool that requires expert-established ground truth on a test set of patient cases for performance evaluation. The "ground truth" for the non-clinical tests refers to the established scientific standards and criteria outlined by ISO, ASTM, and USP.

4. Adjudication Method for the Test Set

Not applicable, as there was no clinical test set requiring expert adjudication.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was Done

No. The document explicitly states: "Clinical testing was not necessary for the determination of substantial equivalence, or safety and effectiveness of the CenterMed ASP System." Therefore, an MRMC comparative effectiveness study was not performed.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was Done

The device is described as a "software system and image segmentation system" and a "pre-operative software tool." While the software components are validated ("Software validation" section), this validation focuses on the correct implementation of specifications and mitigation of risks. It is not framed as a standalone performance study in the sense of an algorithm making decisions or predictions independently. The workflow involves trained engineers operating the software and physicians evaluating the outputs for surgical planning. The "standalone" performance being assessed here is the functional integrity and safety of the software and physical outputs according to design specifications, rather than a diagnostic performance metric.

7. The Type of Ground Truth Used

For the non-clinical studies described:

  • Mechanical Testing: Ground truth is derived from the established physical properties and limits defined by the ISO and ASTM standards.
  • Biocompatibility Testing: Ground truth is the biological safety criteria outlined in the ISO 10993 series and USP <151>.
  • Sterilization Validation: Ground truth is the defined sterility assurance level (SAL) of 10^-6^ as per ANSI/AAMI/ISO 17665-1.
  • Software Validation: Ground truth is the "pre-defined requirement specifications" for the COTS software components, ensuring they function as intended.

No pathology, expert consensus on patient images, or outcomes data were used as ground truth, as no clinical study directly evaluating algorithm performance on patient cases was conducted.

8. The Sample Size for the Training Set

Not applicable. The document does not describe the development of a machine learning algorithm that requires a "training set" of data. The software components mentioned are "Commercially off-the-shelf (COTS) software applications for image segmentation and processing." These are pre-existing software tools, not a newly developed AI algorithm that would undergo a training phase by CenterMed.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as there was no training set for a newly developed AI algorithm. The COTS software validation focused on their correct implementation and functionality within the CenterMed ASP System.

2 General Workflow

The general workflow of CenterMed Patient Matched Surgical Planning System begins with software simulation of patients' imaging data files obtained from the surgeon for treatment planning. Products (surgical guides, surgical splints and anatomical models) are designed based on these imaging data files, converted to 3D STL files, and sent to manufacturing to be preprocessed, printed, and post-processed. Simultaneously, a surgical planning case report is created based on the same imaging data files as well as the STLs of the designed products. The completed output of the system includes the surgical planning case report, anatomical models, and corresponding surgical guides and/or surgical splints. These are packaged, labeled, and sent to the surgeon clean and non-sterile. The surgeon or relevant hospital staff will sterilize the surgical guides, surgical splints and anatomical models before use in the operating room. The workflow is shown in Figure 1.

5 Differences from Predicate

  • Subject device creates anatomical models using Polyamide-12 (PA-12) material with a . SLS manufacturing process, whereas the predicate device uses resin material with an SLA manufacturing process.
  • . Compared to that of the predicate device, the subject device's input data also includes patients' teeth models (either physical or digital models) and patients' digital photos.
  • For the predicate device, manufacturing materials include epoxy/resin and acrylic for . anatomical models, methacrylate for splints, and polyamide, Titanium Alloy (Ti-6A1-4V) and CP Titanium for guides. The subject device only uses PA-12 to manufacture all anatomical models, surgical guides, and surgical splints.
  • . The predicate device provides two kinds of surgical guides, one made with polyamide and the other made with Titanium Alloy (Ti-6Al-4V) and CP Titanium. The subject device only uses surgical guides made of polyamide, along with medical grade 316L stainless steel sleeves. Surgical splints of the subject device are made with the same manufacturing process as the surgical guides, both using polyamide as the raw material.
  • . The predicate device guides are used for bone cutting or marking, while those of the subject device are provided in three types: bone cutting, bone marking, and bone repositioning.
  • . The predicate device uses previously cleared fixation screws which range from 1.5mm -2.7mm diameter, with length of 4mm - 22mm. The subject device recommends a range of standard screw sizes to the doctor (diameter 1.5mm - 2.1mm, length 5mm - 22mm) (Standard screw sizes determined by manufacturer catalogs of medical grade screws for maxillofacial surgeries).
  • The predicate device utilizes four (4) commercially off-the-shelf (COTS) software . applications for image segmentation and processing, whereas the subject device utilizes three (3) commercially off-the-shelf (COTS) software applications for image segmentation and processing, and two (2) commercially off-the-shelf (COTS) software for manufacturing.
  • The predicate device has one contraindication that is not present in the subject device. . "Bone tumors located in the implant base region". The subject device does not include implants and therefore this contraindication is not relevant to the subject device. All other contraindications are identical to the predicate device.

8 Clinical Performance Data

Clinical testing was not necessary for the determination of substantial equivalence, or safety and effectiveness of the CenterMed ASP System. The predicate device did not perform clinical testing for their products (surgical guides, splints, anatomical models, case reports), and since there are no significant technological differences, or significant indications for use differences between the subject device products (surgical guides, surgical splints, anatomical models, surgical planning case reports) and the predicate device, clinical testing is not needed for the subject device.

9 Animal Studies Data

Animal testing was not necessary for the determination of substantial equivalence, or safety and effectiveness of the CenterMed ASP System. The predicate device did not perform animal testing for their products (surgical guides, splints, anatomical models, case reports), and since there are no significant technological differences, or significant indications for use differences between the subject device products (surgical guides, surgical splints, anatomical models, surgical planning case reports) and the predicate device, animal testing is not needed for the subject device.

10 Conclusions

The predicate device chosen was KLS Martin Individual Patient Solutions System. It was shown that the subject device, CenterMed Assisted Surgical Planning System is substantially equivalent to the predicate device. Both have the same indications for use as a software and image segmentation system for the transfer of imaging information from a medical scanner, and both result in creation of outputs such as anatomical models, surgical guides, surgical splints and surgical planning case reports for use in maxillofacial surgery. Both create physical outputs using rapid prototyping. They are both intended for use as a pre-operative software tool for simulating and evaluating surgical treatment options.

Any differences between the predicate device and the subject device have been thoroughly analyzed to conclude no safety or efficacy issues in the subject device. A full risk analysis was performed to determine the safety of the device, and any residual risk has been justified. Additionally, mechanical, biocompatibility, and sterilization tests have been performed. All tests passed their respective test criteria. Software risk analysis and validation was also performed of the COTS software used to design and manufacture the subject device.

Based on the comparisons and analyses detailed above in this summary, we believe that the information and performance test reports of the subject device provided in this 510(k) submission are sufficient to demonstrate and provided support the conclusion of Substantial Equivalence to the predicate device.
