In this 3D walkthrough, we show how the LVIS® Jr functions as a low-profile, visualized intraluminal support stent to enable stent-assisted coiling of wide-neck intracranial aneurysms. Deployed through a microcatheter into small, distal vessels, LVIS Jr is placed across the aneurysm neck to provide scaffolding while embolization coils are delivered into the sac—helping keep coils contained and supporting durable occlusion. In the United States, LVIS/LVIS Jr are indicated for use with neurovascular embolization coils to treat wide-neck saccular aneurysms (neck: 4 mm or dome-to-neck: 2 mm) arising from parent vessels 2.0–4.5 mm in diameter in adults—the exact anatomy this visualization highlights. -- Connect with Terumo Neuro: https://www.instagram.com/terumoneuro/ https://www.linkedin.com/company/terumoneuro/ https://x.com/terumoneuro

The video is a 3D animation of Terumo Neuro’s LVIS® and LVIS® Jr. devices supporting coil embolization of wide-neck aneurysms. It shows microcatheter delivery and deployment across the aneurysm neck, where the braided implant provides a scaffold to keep coils inside the sac. With the scaffold in place, detachable coils are packed to promote occlusion while maintaining parent-artery and branch-vessel flow. Radiopaque markers guide placement, and the device can be resheathed before detachment, emphasizing a precise, minimally invasive workflow. -- Connect with Terumo Neuro: https://www.instagram.com/terumoneuro/ https://www.linkedin.com/company/terumoneuro/ https://x.com/terumoneuro

Visish M. Srinivasan, MD, Aditya Vedantam, MD, and Peter Kan, MD, MPH Department of Neurosurgery, Baylor College of Medicine, Houston, Texas We present a case of a patient with an anterior communicating artery aneurysm treated by PulseRider-assisted coil embolization. PulseRider is a new device, FDA approved for treatment of broad-necked aneurysms of the basilar apex or internal carotid artery terminus. The aneurysm was broad-necked and involved the anterior communicating artery and was considered for traditional stent-assisted coiling as well as PulseRider-assisted coiling. The authors present the treatment plan and strategy and then fluoroscopic recording of the PulseRider delivery and subsequent coiling phase. Nuances of technique for this new device used in a challenging setting are discussed.

The pCONus is a new category of intraluminal device intended to treat complex, wide neck intracranial bifurcation aneurysms. It is designed to support the coil mass at the level of the neck of those aneurysms that cannot be easily coiled or surgically treated.

Endovascular (meaning within the blood vessel) embolization, or coiling, uses the natural access to the brain through the bloodstream via arteries to diagnosis and treat brain aneurysms. The goal of the treatment is to safely seal off the aneurysm and stop further blood from entering into the aneurysm and increasing the risk of rupture or possibly rebleeding. A small incision is made over the artery and a needle is used to puncture the blood vessel. A sheath (hollow thin tube) is then placed in the artery, which provides constant access to the artery. This catheter sheath can remain in the artery for 24 to 48 hours after the procedure, so that further interventions can be performed, if necessary. Using a catheter (hollow plastic tube) over a guiding wire, the artery leading to the aneurysm is selected. The wire is removed and the catheter is used to inject a contrast dye into the blood stream in order to visualize the normal blood vessels as well as delineate the aneurysm. The entire process is done using continual x-ray visualization and high-speed radiographic filming techniques. The doctor takes measurements and views of the aneurysm. Once the angiogram has detected the presence, size, and location of the aneurysm, a smaller "micro catheter" is then placed inside the initial catheter. Once the micro catheter is successfully navigated into the aneurysm opening, the coil system is introduced. Platinum coils are deposited into the aneurysm, reducing or blocking the flow of blood into the aneurysm. Once placed inside the aneurysm, a small electrical current is passed through the wire. As a result of this electrolysis, the coil detaches from the wire and remains inside the aneurysm. The wire is removed. It may take several coils to obliterate the aneurysm. In some cases the opening into the aneurysm may be wide, and a balloon or a small stent can be placed inside the blood vessel along the neck of the aneurysm to assist in the coiling procedure. If a balloon is used, it is deflated and removed at the end of the procedure. If a stent is used, it is implanted permanently into the artery, sometimes in a separate procedure, prior to coiling. The stent acts as a scaffold inside the artery to help keep the coils in place inside the aneurysm. After aneurysm packing with coils, the catheter systems are removed and the patient is transferred to the Intensive Care Unit for monitoring and further care.

A brain aneurysm is a weak area in a blood vessel wall that causes the vessel to bulge or balloon out and sometimes burst.
