Dredger mechanical thrombectomy stent retriever is a device that is designed to remove blood clots in the cerebral vasculature. They consist of a mesh-like stent attached to a delivery platform, which is inserted into the artery and navigated to the site of occlusion. The stent is then deployed, creating a mesh that traps the clot within its struts. Once the stent retriever is fully deployed, it is withdrawn with the clot, thereby restoring blood flow to the affected area of the brain.

One of the key features of DredgerTM mechanical thrombectomy stent retriever is their mechanical thrombectomy capability. Unlike thrombolytic agents, which are drugs that dissolve blood clots, stent retrievers physically remove the clot, allowing for faster and more effective revascularization. Moreover, stent retrievers have a higher recanalization rate than thrombolytic agents, which translates into better clinical outcomes. DredgerTM stent retriever devices come in different sizes and shapes to suit different anatomies and occlusions. They are made of radiopaque materials that can be visualized under imaging modalities, such as fluoroscopy, angiography or computed tomography, which is crucial in guiding the operator to the site of occlusion and monitoring the procedure.
