Releases

New and updated cases

• 4 new Flow diversion cases with more complex and challenging aneurysms to allow for more advanced training
• Added full guidance for one AIS case, to learn the basic steps and to allow for unproctored training
• 2 new larger and more complex AVMs to allow for more advanced training, handling multiple feeders and reflux
• Updated and refined anatomies, including adding ophthalmic arteries where previously missing, to improve the fidelity of the challenges presented during cerebral navigation

‍

New features and improvements

• Ready for case rehearsal of flow diversion cases planned using Ankyras validated planning platform
• A completely new and more realistic model for flow diverters enabling flow diversion in more complex and challenging anatomies, improving thefidelity of the training
• Foreshortening based on Ankyras’ validated algorithm to align training with planning and to better understand the complexity of flow diverters
• Increased visibility of embolic agent for increased realism and better training
• Updated portfolio of intracranial stents to better represent the real devices used
• New look and feel to improve usability
• Automatic calibration for measurements and possibility to zoom when roadmaps are used to better align with the features found in the angio suite
• Switched position of frontal and lateral planes to align with the most common setup in the angio suite
• High-resolution forces on latest generation of G7 for improved realism and for the operator to better appreciate and understand the nuances of the friction forces during neuro intervention
• Ready for automatic updates to speed-up and facilitate more frequent updates of the solution, to always be updated with the latest version
• Onlinebug and feedback reporting available

‍

The VIST NV connect module is a new common NV platform for neurovascular procedures. All neurovascular cases are now available in the same environment, where continuous updates and improvements will be a natural part of this new platform. New procedures and cases will be regularly added, based on market input.

This first release of the platform is a technical release and introduces an updated and consolidated version of existing neurovascular procedures for VIST.

The VIST NV Connect module is also part of a broader concept based on a common subscription offering, an integrated planning, rehearsal, and training solution for interventional neuroradiology. Supported by high-end simulation and connected online services, it bridges the gap between industry and physicians, fostering collaboration and excellence.

‍

Features & Highlights

All NV procedures available in the same module

• Flow Diversion (FD)
• Intracranial Atherosclerosis Disease (ICAD)
• Acute Ischemic Stroke (AIS)
• Carotid Intervention
• Arteriovenous Malformation (AVM)
• Cerebral Aneurysm Coiling

Anatomies and lesion

Updated NV anatomies with multiple lesion locations per procedure. Radial and femoral access.

Bifurcation for Assisted Coiling cases

Applicable for G7+ and G7 2024 with bifurcation license.

‍

Procedure tab with useful features for the trainee

• Show access path
• Show landing zones
• Remove deployed implant
• Show thrombi
• Pause device movement

‍

3D-RA tab

Allows the trainee with the positioning and sizing of both lesions and devices.

‍

Place tool

This functionality allows the trainee to skip the access and to train directly on the procedure. This feature is available for all procedures except for the Carotid Intervention.

‍

Benchmarks per procedure

Each type of procedure has specific benchmarks based on the metrics applicable for the chosen procedure (e.g. in Coiling procedures the metrics measure aneurysm filling, while in AIS the metrics look for the remaining thrombi).

‍

Improved physics

• Physics behavior of catheters
• Increased friction and force feedback with smaller forces such the forces in the NV procedures

Release date: 2024-11-01

‍

Changes:

• Fix of a bug related to post-dilation of self-expandable stents
• Adding metrics recording whether manual or quick access has been used
• Fix of a bug related to the pop-up windows when exchanging the 0.014'' wire by the EPD filter in the Carotid cases
• Improvement of device behavior in steep take-offs and tortuosities
• Improvement of contrast injection configuration
• Message informing “The clot is free” has being disabled if the clot has already been removed

Release Date: 2024-10-07

Updates:

• AVM:
  • Glue attenuation improved for a more realistic looking in fluoro
  • Warning for “too low injection pressure”
  • Glue injection only available for 0.010’’ microcatheters
• Warning activated for “Coil detached inside catheter”
• Warning for “Stent deployed inside catheter” is removed from flow diverters and stentrievers, since the warning isn’t needed for those devices
• Warning for “Distal angiogram needed” is removed in AIS before the stentriever selection
• “Detach” button is inactive after it is being clicked once, to make it clear for the user that the detachment has already been done
• The anatomy in two cases is updated to eliminate a couple of artifacts in the heart
• EPD filter added in all the procedural messages where it was missing in the previous version of the software
• Fixed an issue with stentrievers and other self-expanding stents that rotates when partly deployed
