The document describes image processing and computational modeling for device sizing and placement, but there is no mention of AI or ML algorithms being used for these functions. The "automatic" features described appear to be based on traditional image processing techniques and geometric calculations.
No.
This device is a pre-operative planning and sizing tool, not a device that directly treats or prevents a condition.
No
The device is intended for pre-operational planning and sizing for neurovascular interventions and surgery, the computational modeling of device placement, and visualization of cerebral blood vessels. It is explicitly stated that "Information provided by the software is not intended in any way to eliminate, replace or substitute for, in whole or in part, the healthcare provider's judgment and analysis of the patient's condition." This indicates it is a planning and visualization tool, not a diagnostic one.
Yes
The device description explicitly states "The Sim&Size software is a medical device intended to provide a 3D view...". The entire description focuses on the software's functionalities, modules, and steps for processing image data and performing computational modeling. There is no mention of accompanying hardware components that are part of the medical device itself. While it uses input from imaging modalities and is installed on standard computer operating systems, the device being regulated is the software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze specimens from the human body. The core function of an IVD is to examine samples like blood, urine, tissue, etc., to provide information about a patient's health.
- This device analyzes medical images. Sim&Size processes 3D rotational angiography images of cerebral blood vessels. It does not analyze biological specimens.
- The intended use is for preoperational planning and sizing. The software is used to visualize and model the placement of neurointerventional devices based on imaging data, not to diagnose a condition through laboratory analysis of a specimen.
Therefore, Sim&Size falls under the category of a medical device that processes and analyzes medical images for clinical planning purposes, rather than an In Vitro Diagnostic device.

Device Description
The Sim&Size software is a medical device intended to provide a 3D view of the final placement of implants. It uses an image of the patient produced by 3D rotational angiography. It offers clinicians the possibility of computationally model neurovascular implantable medical devices (IMD) in the artery or in the aneurysm to be treated through endovascular surgery, IMD such as the flow-diverters (FD) and the intrasaccular devices (ISD).
Sim&Size is a software designed with two modules. FDsize is the module that allows to preoperationally plan the choice of size of flow-diverter devices. IDsize is the module that allows to preoperationally plan the choice of size of intrasaccular devices.
Associated to these two modules, a common module is intended to import DICOM and to provide a 3D reconstruction of the vascular tree in the surgical area.
Sim&Size has been simplified as much as possible to guide the user in an intuitive way in order to reduce the total number of actions required and thus to optimize the time taken to obtain the desired results. There are currently seven steps required to choose the optimal size of an IMD to be placed:
- 1- Importing the images: the 3D rotational angiography DICOM files are imported.
- 2- Selecting of the region of interest (ROI): the user positions and focuses a sphere in the placement zone.
- 3- Threshold validation: the user checks the accuracy of the automatically extracted arterial wall. The threshold can be adjusted if needed.
- 4- Choosing the entry point: the user clicks on the entry point to the arterial network in order to retrieve the vessel centerlines.
- 5- Correct automatically or manually the centerline if needed: the user corrects the centerline going through a vessel fusion with the automatic tool or manually.
- 6- Initializing the implant: the user selects an IMD reference and the ideal placement zone.
- 7- Sizing the implant: IMD apposition is shown by a color chart in the 3D view. The user can change the IMD reference and placement zone to complete the planning for the intervention.
Patient images can be imported into Sim&Size in two ways: the user has the ability to transfer images using an external storage device (e.g. USB stick) or to retrieve images directly from Scanners Workstation if the option is enabled (only the retrieve function is possible).
The Sim&Size software is compatible with the operating systems MS Windows and Mac OS, when it is first installed a check is done to verify if the user's computer meets the minimum requirements for the use of the software. When a new version of the software is available, the update can be done by the user through a link send by Sim&Cure, the user then follow the instructions indicated in the user manual or by the use of the updater tool SacUpdates that notifies the user, then assists the download and the installation of the last version.
The computational modeling of three devices are supported by the software: Medtronic Pipeline Flex Embolization Device (PED - P100018/S015) flow diverter: Stryker Surpass Evolve Flow Diverter System (Evolve - P170024 S003); and Microvention Woven EndoBridge Aneurysm Embolism System (WEB - P170032) intrasaccular devices. The Medtronic Pipeline Flex Embolization Device, Stryker Surpass Evolve Flow Diverter and Microvention Woven EndoBridge Aneurysm Embolism System devices referenced here are FDA-approved neurointerventional devices.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Software Verification and Validation Testing:
Software verification and validation testing were conducted as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" in section 16. The software was considered a "moderate" level of concern.
Performed tests:
- Tests of importation of DICOM images.
- Patient manager tests.
- Tests of image display and processing.
- Functioning tests for visualization of anatomic reconstruction.
- Report creation and visualization tests.
- Fusion correction tests (automatic and manual).
- Cybersecurity tests.
Key results: The new feature of manual fusion correction has been tested and the tests are passed. The cybersecurity testing has been improved and all the tests are passed. No regression between the predicate device and version 1.0.6. All continuous, supervised, and acceptance tests passed.
Performance Testing - Bench, functioning tests for computational modeling of neurovascular devices:
FDsize module:
- Verification testing: checks that the Flow Diverter final length and apposition computed through the software are conform to their mathematical definition.
- Validation tests: Experimental benchtests (optical acquisitions of new IMD devices samples in unconstrained and constrained configurations), Realistic in vitro (silicone model) datasets (predictability of the simulation model assessed comparing in-vitro and virtual Flow Diverters devices implanted in silicone phantom of patients presenting with intracranial aneurysms), In vivo studies (results based on comparisons between FD implanted in patients presenting with intracranial aneurysms and virtual FD deployment).
Key result: The results obtained in these verification and validation studies allow to demonstrate that the inclusion of the new Implantable Medical Devices databases in the Sim&Size software have no impact on the safety and performance of the device.
IDsize module:
- Verification testing: verification and validation of the new in-house mechanical solver (Sim&Cure Finite-Element (sacFE) solver). A variety of verification test cases were performed.
- Validation tests: Experimental benchtests (assess accuracy of IDsize computational model in a well-controlled experimental configuration), Realistic in vitro (silicone model) datasets (comparison done between implanted in silicon phantoms of idealized aneurysms anatomies and virtual WEB computationally modeling with Sim&Size), In vivo studies (results based on comparisons between WEB implanted in patients presenting with intracranial aneurysms and virtual WEB deployment).
Key result: The new simulation model appeared to be more robust than the old one and better captures the mechanical behavior of the device when subjected to the compression solicitation than the old simulation model. The new and old model provide a similar overall accuracy. Integration of the new mechanical solver and the model change in the Sim&Size software have no impact on the safety and performance of the device.
Overall: All performance testing has been performed and passed. The software Sim&Size in its last version 1.0.6 has met the required specifications for the completed tests.

- verify the proper calibration of the simulation model with the device geometrical O parameters that were provided by each of the device manufacturers.
- assess the predictability of the product Sim&Size for the new IMDs. O
The results obtained in these verification and validation studies allow to demonstrate that the inclusion of the new Implantable Medical Devices databases in the Sim&Size software have no impact on of the safety and performance of the device.
IDsize module
- The verification testing provides the verification and validation of the new in-house mechanical ● solver. The simulation model is based on this solver, for which a variety of verification test cases were performed. The significant amount of performed verification test cases makes us confident about this in-house solver and enables us to rule on the proper verification of the computational model.
- The validation tests are:
- Experimental benchtests which assess the accuracy of the IDsize computational model in a o well-controlled experimental configuration.
- Realistic in vitro (silicone model) datasets in which a comparison is done between O implanted in silicon phantoms of idealized aneurysms anatomies and virtual WEB computationally modeling with Sim&Size.
- In vivo studies for which the results are based on comparisons between WEB implanted in O patients presenting with intracranial aneurysms and virtual WEB deployment.
These validation testing allows to:
- Demonstrate that the new simulation model appeared to be more robust than the old one and o better captures the mechanical behavior of the device when subjected to the compression solicitation than the old simulation model.
- Assess the predictability of the product Sim&Size for the Intrasaccular Device WEB. o
- Demonstrate that the new and old model provide a similar overall accuracy. O
The results presented in these verification and validation studies allow to demonstrate that integration of the new mechanical solver and the model change in the Sim&Size software have no impact on of the safety and performance of the device.
All performance testing has been performed and passed.
The software Sim&Size in its last version 1.0.6 has met the required specifications for the completed tests.
8. Summary
