Intended Use

Sim&Size enables visualization of cerebral blood vessels for preoperational planning and sizing for neurovascular interventions and surgery. Sim&Size also allows for the ability to computationally model the placement of neurointerventional devices. General functionalities are provided such as: - Segmentation of neurovascular structures - Automatic centerline detection - Visualization of X-ray based images for 2D review and 3D reconstruction - Placing and sizing tools - Reporting tools 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.

Device Story

Sim&Size is a standalone SaMD for preoperational planning of neurovascular interventions. It takes 3D rotational angiography DICOM images as input. The software performs segmentation of neurovascular structures and automatic centerline detection. Clinicians use the device to simulate the placement of various neurointerventional implants (flow-diverters, intrasaccular devices, stents, and coils) within the patient's vascular anatomy. The system provides tools for sizing, positioning, and measuring the simulated implants. Outputs include simulation reports (PDF/DCM/VTP) and reconstructed vascular models. Used in clinical settings by physicians to assist in surgical planning; the software does not replace clinical judgment. Benefits include improved pre-procedural assessment of device fit and deployment, potentially optimizing treatment outcomes.

Clinical Evidence

Bench testing only. Testing included software verification and validation per FDA guidance, comparison of predictive behavior versus theoretical behavior, bench testing using silicone phantom models, and retrospective in vivo testing comparing in vitro cases with device simulations.

Technological Characteristics

Standalone software running on standard PC (Windows/Mac). Inputs: DICOM 3D rotational angiography. Features: Segmentation, centerline detection, 3D reconstruction, and simulation modules (FDsize, IDsize, STsize, FCsize). Connectivity: Local files, physical media, or PACS (query/retrieve). Output: PDF, DCM, VTP files. No patient contact. Non-invasive.

Indications for Use

Indicated for preoperational planning and sizing for neurovascular interventions and surgery, including computational modeling of neurointerventional device placement in cerebral blood vessels.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management.
