The WEB™ Embolization System is first-in-class intrasaccular technology offering a single-device treatment alternative to endovascular coils and complex stenting procedures. The intrasaccular embolization system minimizes the need for a dual antiplatelet regimen required for intraluminal therapies.


The WEB Aneurysm Embolization System is indicated for use at the middle cerebral artery (MCA) bifurcation, internal carotid artery (ICA) terminus, anterior communicating artery (AComm) complex, or basilar artery apex for the endovascular treatment of adult patients with saccular, wide neck bifurcation intracranial aneurysms with dome diameter from 3 mm to 10 mm and either neck size 4 mm or greater or the dome-to-neck ratio is greater than 1 and less than 2.

The WEB Aneurysm Embolization System is contraindicated for patients with known bacterial infection that may interfere with or negatively affect the implantation procedure and patients with known hypersensitivity to nickel. For complete indications, contraindications, potential complications, warnings, precautions, and instructions, see instructions for use (IFU provided in the device).


The VIA™ Catheter is intended for the introduction of non-liquid interventional devices (such as stents/flow diverters) and infusion of diagnostic (such as contrast media) or non-liquid therapeutic agents into the neuro, peripheral, and coronary vasculature. The VIA Catheter is contraindicated for use with liquid embolic materials, such as n-butyl 2-cyanoacrylate or ethylene vinyl alcohol & DMSO (dimethyl sulfoxide). The VIA Catheter is contraindicated for use in the pediatric population (<22 yrs of age).

Features and Benefits

Simple

Single-device solution for complex aneurysms.


Innovative

The WEB device is constructed from a unique MicroBraid that facilitates ease-of-use and treatment durability.


Effective

Multiple GCP studies prove the safety and effectiveness of the device in a challenging aneurysm category.



Recommended Compatible Devices

The VIA microcatheter was specially designed for dedicated use with the WEB device to maximize system performance. The VIA microcatheter ensures smooth delivery, controlled deployment and reliable retrieval of the WEB device.

Use Case Examples

The WEB Aneurysm Embolization System is indicated for use at the middle cerebral artery (MCA) bifurcation, internal carotid artery (ICA) terminus, anterior communicating artery (AComm) complex, or basilar artery apex for the endovascular treatment of adult patients with saccular, wide neck bifurcation intracranial aneurysms with dome diameter from 3 mm to 10 mm and either neck size 4 mm or greater or the dome-to-neck ratio is greater than 1 and less than 2.

Safety informations

Non-clinical testing demonstrated that the WEB Aneurysm Embolization Device is MR Conditional. A patient with this device can be scanned safely in an MR system under the following conditions:

- Static magnetic field of 3-Tesla or less

- Maximum spatial gradient magnetic field of 4,000-Gauss/cm (40-T/m)

- Maximum MR system reported, whole body averaged specific absorption rate (SAR) of 2-W/kg for 15 minutes of scanning (i.e., per pulse sequence) in the Normal Operating Mode

 

Under the scan conditions defined, the WEB Aneurysm Embolization Device is expected to produce a maximum temperature rise of 1.4˚C after 15-minutes of continuous scanning (i.e., per pulse sequence).

In non-clinical testing, the image artifact caused by the WEB Aneurysm Embolization Device extends approximately 5-mm from this implant when imaged using a gradient echo pulse sequence and a 3-Tesla MR system.
