Clinical trials

The objective of this study is to assess the safety and effectiveness of mechanical thrombectomy (MT) using the ANA funnel catheter in its intended use, which is to facilitate the navigation and deployment of other neurovascular devices and to allow flow arrest during mechanical thrombectomy procedures performed in subjects experiencing acute ischemic stroke (AIS) secondary to large vessel occlusion (LVO) and treated within 24 hours of symptom onset.

The goal of this study is to evaluate the safety and performance of the CONDA stent retriever in patients with acute ischemic stroke due to large vessel occlusion, treated within 24 hours of symptom onset. The main objectives are: * To determine the rate of device success, defined as the ability of the CONDA retriever to reach the blocked vessel, be deployed and retrieved successfully, and facilitate reperfusion. * To evaluate safety, measured as the rate of symptomatic intracranial hemorrhage within 24 hours of the procedure. The use of CONDA in this study follows the same approach as other CE-marked stent retrievers. Supportive devices (such as long sheaths, guide catheters, balloon catheters, distal access catheters, the ANA funnel catheter, microcatheters, and microwires) may be used according to investigator preference and local practice, in line with their labeling and instructions for use. Participants will: * Be evaluated using standard clinical and imaging assessments to confirm eligibility. * Undergo mechanical thrombectomy with the CONDA device, with or without supportive devices as selected by the treating physician. * Have standard follow-up evaluations to assess treatment safety and effectiveness.
