The summary describes a software system for image segmentation and surgical planning, and a process for creating physical models from digital data. While it mentions image processing and a "stand-alone software package," there is no explicit mention of AI, ML, deep learning, or any related terms or concepts that would indicate the use of these technologies. The performance studies focus on the accuracy of the production process and the resulting models, not on the performance of an AI/ML algorithm.
No.
The device is intended for image segmentation and pre-operative surgical planning, and produces physical replicas for adjunctive use in diagnosis, patient management, and treatment selection. It does not directly provide therapy.
No
The PRE-SURE software system and its physical replicas are intended for "adjunctive use along with other diagnostic tools and expert clinical judgement for diagnosis". This means the device itself is not a diagnostic tool but rather an aid that complements other diagnostic methods.
No
While the system includes a software component for image processing and surgical planning, it explicitly describes the creation of physical replicas (3D printed models) as part of its intended use and device description. The performance studies also include testing related to the accuracy and materials of these physical models.
Based on the provided information, the PRE-SURE software system is not an In Vitro Diagnostic (IVD).
Here's why:
- IVD Definition: An IVD is a medical device used to perform tests on samples such as blood, urine, or tissue to detect diseases or other conditions. These tests are performed outside of the body (in vitro).
- PRE-SURE's Function: The PRE-SURE system processes medical imaging data (DICOM) to create digital and physical anatomical models. It is used for surgical planning and as an adjunctive tool for diagnosis, patient management, and treatment selection.
- Lack of Sample Testing: The PRE-SURE system does not perform any tests on biological samples. Its input is imaging data, not biological material.
- Focus on Anatomical Modeling: The core function is the creation of anatomical models for visualization, planning, and physical representation.
While the physical replica is intended for adjunctive use along with other diagnostic tools, the PRE-SURE system itself is not performing a diagnostic test on a biological sample. It is a tool that aids in the interpretation and utilization of existing diagnostic imaging data.
N/A
Intended Use / Indications for Use
The PRE-SURE software system is intended for use as a software interface and image segmentation system for the transfer of DICOM imaging information from a medical scanner to an output file. It is also intended as pre-operative software for surgical planning. For this purpose, the output file may be used to produce a physical replica. The physical replica is intended for adjunctive use along with other diagnostic tools and expert clinical judgement for diagnosis, patient management, and/or treatment selection of genitourinary applications.

Device Description
End Users of the PRE-SURE device receive digital and/or physical patient anatomical models from Lazarus 3D. The physical models are intended for adjunctive use along with other diagnostic tools and expert clinical judgement for diagnosis, patient management, and/or treatment selection of genitourinary applications. Digital models may be viewed by End Users using any program cleared for their intended use.
The PRE-SURE patient modeling system is a method for the creation of patient models. This system will be used exclusively by Lazarus 3D, with some physician input and feedback, to produce models for End Users. Importantly, and unlike other 3D modeling systems, in the PRE-SURE process the design and production of patient models is performed by Lazarus 3D and not by the End User or a third party. The internal process within Lazarus 3D used for creating PRE-SURE patient models includes use of an FDA cleared stand-alone software package. As a part of the PRE-SURE production process, this software is intended for internal use within Lazarus 3D to create digital anatomical models from patient radiological data that can be used by End Users for a variety of uses such as training, education, and pre-operative surgical planning.
The patient specific digital anatomical models may be further used as an input to a 3D printing-based production process performed by Lazarus 3D to create physical patient models. Each individual patient's model can be created rapidly from the patient's radiological data using Lazarus 3D's patented rapid prototyping technology. The resulting physical models of patient anatomy are primarily composed of silicone materials that can be cut, can be sutured, and in some cases can even bleed.

The PRE-SURE patient modeling system is a method for the creation of patient models. This system will be used exclusively by Lazarus 3D, with some physician input and feedback, to produce models for End Users. Importantly, and unlike other 3D modeling systems, in the PRE-SURE process the design and production of patient models is performed by Lazarus 3D and not by the End User or a third party. The internal process within Lazarus 3D used for creating PRE-SURE patient models includes use of an FDA cleared stand-alone software package. As a part of the PRE-SURE production process, this software is intended for internal use within Lazarus 3D to create digital anatomical models from patient radiological data that can be used by End Users for a variety of uses such as training, education, and pre-operative surgical planning.
The patient specific digital anatomical models may be further used as an input to a 3D printing-based production process performed by Lazarus 3D to create physical patient models. Each individual patient's model can be created rapidly from the patient's radiological data using Lazarus 3D's patented rapid prototyping technology. The resulting physical models of patient anatomy are primarily composed of silicone materials that can be cut, can be sutured, and in some cases can even bleed.
5. INDICATIONS FOR USE
The PRE-SURE software system is intended for use as a software interface and image segmentation system for the transfer of DICOM imaging information from a medical scanner to an output file. It is also intended as pre-operative software for surgical planning. For this purpose, the output file may be used to produce a physical replica. The physical replica is intended for adjunctive use along with other diagnostic tools and expert clinical judgement for diagnosis, patient management, and/or treatment selection of genitourinary applications.
6. SUBSTANTIAL EQUIVALENCE DISCUSSION
PRE-SURE employs similar fundamental technologies as the identified predicate device, including:
- . Viewing of medical imaging data in the axial, coronal, and sagittal views
- Ability to process, review and analyze medical imaging data
- lmage transfer and manipulation via software used for the creation of a 3D object.
- Use of the 3D object for diagnosis, patient management and/or treatment selection.

The logo consists of a blue and orange diamond shape on the left, followed by the text "LAZARUS 3D" in a bold, sans-serif font. Below the company name is the tagline "Operate with confidence" in a smaller, regular font.
However, in the PRE-SURE process the analysis of patient data and production of patient models is performed by Lazarus 3D and is provided as a service to End Users. By contrast, the predicate device is sold as a software and hardware package that allows End Users or third parties to produce their own patient models. Additionally, while the predicate patient models are produced in relatively hard materials (e.g., plastics), PRE-SURE physical models can be created in soft silicone materials that can be cut, sutured, and in some cases even bleed. Both devices can be used to create a physical rendering of radiological data for visualization and analysis. However, the additional capabilities of PRE-SURE models may provide new opportunities for pre-surgical planning and rehearsal.

7. NON-CLINICAL PERFORMANCE DATA
The following performance data were provided in support of the substantial equivalence determination:
Production Process Accuracy Study
The purpose of this accuracy study was to evaluate the accuracy of PRE-SURE patient model production processes. Models of various dimensions were created using PRE-SURE from computer models with dimensions pre-defined in silico. Comparisons were made between the physical models created using PRE-SURE and the in-silico input data, revealing that measurements fell within pre-defined acceptance criteria.
Digital and Physical Model Accuracy Study
The purpose of this accuracy study was to compare results from the entire PRE-SURE workflow to those of the predicate device. MRI and CT scan input data from actual cases were analyzed using the predicate and subject devices to create 3D computer models and

physical models of the patient anatomy. These models were then compared, revealing that measurements fell within pre-defined acceptance criteria.
Build Envelope Testing - Accuracy Validation
The purpose of this study is to define where on the 3D printer, and in what orientation, models can be produced in sufficient accuracy for the intended use. Models of genitourinary conditions were built using 3D prints from different locations the 3D printer build plate, and in different orientations. Results show that sufficient accuracy can be achieved for models built in any orientation or position.
Materials Testing - Accuracy Validation
The purpose of this study is to test the accuracy and bonding of the range of materials included in the build envelope for PRE-SURE physical patient models. Multi-material genitourinary models were produced using combinations of the most difficult to use materials within the PRE-SURE build envelope. Testing shows that all materials and material combinations produce models of sufficient accuracy for the intended use. Additionally, all tested materials bond well with all other tested materials and thus can be used together to form multi-material patient models.
Testing on Especially Challenging Genitourinary Cases
The purpose of this study is to test was to test the accuracy of the subject production process when creating complex genitourinary models. Models of three conditions that are difficult to produce for a variety of reasons were manufactured. These physical models were analyzed using a CT scanner and volumetrically compared against the digital design. Results indicate that the subject 3D manufacturing process can reproduce complex genitourinary conditions with sufficient accuracy for the intended use.
Summary
All performance testing which was conducted as a result of risk analyses and design impact assessments showed conformity to pre-established specifications and acceptance criteria. The acceptance criteria were established in order to demonstrate the device performance and substantial equivalence to the predicate device.
8. STATEMENT OF SUBSTANTIAL EQUIVALENCE
