Abstract:
Background: In the treatment of giant cerebral aneurysms with flow-diverting stents, access to the distal parent artery is critical but occasionally challenging. This article provides our experience with a novel steerable microcatheter in such a situation, as well as a review of the literature. Case Description: A 73-year-old woman presented with right ptosis and external ophthalmoplegia. Magnetic resonance angiography revealed a giant right cavernous internal carotid artery aneurysm. Endovascular treatment was planned with flow diversion, but distal access was not possible using the standard

Abstract:
Background/Aim: Although transarterial chemo-embolization (TACE) is a key treatment for hepatocellular carcinoma (HCC), its effectiveness depends on the cannulation of the microcatheter tip into the feeding artery. Steerable microcatheters allow remote operation of the tip, enabling its insertion into feeding arteries otherwise difficult to reach. This study investigated the indications and effectiveness of steerable microcatheters in TACE for HCC. Patients and Methods: We retrospectively examined 22 patients with HCC who underwent TACE using steerable microcatheters at our Department between

<strong>Abstract</strong> Ongoing advancements in vascular intervention are fueled by the pursuit of improved patient outcomes and procedural efficiency. This study presents a newly developed steerable microcatheter tailored for the delivery and retrieval of liquid embolic agents in vascular procedures, specifically targeting the obstruction of blood flow to aneurysms. Key to this research is the incorporation of a biocompatible and embolization tip that can be detached from the steerable microcatheter body using thermoplastic sleeves.

Abstract:
Level one trauma centers experience horrific injuries on a regular basis. Blunt or penetrating trauma causing vascular injuries are treated by surgeons and interventional radiologists. When a blood vessel is completely transected, the ends of the vessel retract and vasospasm occurs as a normal survival response. When this phenomenon occurs, it is sometimes impossible to reattach the two ends of the injured vessel by surgical means and a bypass graft is often required. However, from an endovascular perspective, covered stents can serve as a vascular bypass as well. The limiting factor with an e

Abstract:
Catheters used for endovascular navigation in interventional procedures lack dexterity at the distal tip. Neurointerventionists, in particular, encounter challenges in up to 25% of aneurysm cases largely due to the inability to steer and navigate the tip of the microcatheters through tortuous vasculature to access aneurysms. We overcome this problem with submillimeter diameter, hydraulically actuated hyperelastic polymer devices at the distal tip of microcatheters to enable active steerability. Controlled by hand, the devices offer complete 3D orientation of the tip. Using saline as a working

Abstract:
The treatment of carotid stenosis complicated by severe vessel tortuosity can present challenges in distal vessel selection and device delivery. This article reports the use of a steerable microcatheter (SM) for carotid artery stenting (CAS) in such cases. A 67-year-old male with transient lower extremity weakness and bilateral cerebral infarctions was found to have bilateral carotid stenosis. CAS was planned for both carotid arteries due to coronary artery disease. The left carotid artery exhibited severe stenosis with a 90-degree angle between the common and internal carotid artery (ICA). An

ObjectiveTo report our early experience in using the steerable ‘Columbus’ guidewire, also known as ‘Drivewire’ in the USA, and its potential applications in neurovascular interventions.MethodsNeurointerventions in 36 patients (20 female, 16 male) using the steerable Columbus guidewire were recorded from August 2019 to December 2020 and included a variety of neurovascular procedures: Treatment of aneurysms (n=17), thrombectomy in acute ischemic stroke (n=12), and others (n=7), such as treatment of stenosis and embolization procedures. Immediate follow-up with digital subtraction angiography and
