DredgerTM neurovascular stent retriever is a neurosurgical device for the treatment of ischemic stroke. It is used primarily to treat blood clots that block blood vessels in the brain, helping patients restore blood supply and normal brain function. Time is of the essence in the treatment of ischemic stroke. Neurovascular stent retriever acts like a remover, it can remove thrombus through vascular stent, make the blood flow in the brain, reduce the death and dysfunction of nerve cells, thereby reducing the mortality and disability of patients. DredgerTM is applicable for the blockage of large and small blood vessels, including carotid artery, middle cerebral artery and cerebellar artery, the removal rate can reach more than 90%. This means that even if the thrombus is located in a complicated location, the Neurovascular stent retriever can still effectively remove it, improving the success rate of treatment.
Features &Advantages
1. Dredger neurovascular stent retriever is designed with a non-invasive guide wire tip, which can effectively prevent damage to the inner wall of the blood vessel. When performing surgical treatment, it often occurs that the tip of the surgical instrument is slender or too sharp, and the inner wall of the blood vessel is scratched during the operation, causing greater damage.
2. Dredger has a larger push guide rod, which enhances the maneuverability of the device and makes the treatment smoother.
3. A front-end umbrella-type basket design, which has a pocket function, which can prevent small emboli from escaping to the far end, making it safer. When performing endovascular surgery, once a small emboli escapes, it can cause a greater crisis, often requiring more complicated and cumbersome surgical treatment. The front-end protective umbrella basket design of the Neurovascular Stent Retriever can effectively avoid this situation.
4. The device adopts the fourth-generation design concept of the first variable mesh with double-layer movable mesh, and the success rate of the first thrombectomy is higher. When performing endovascular surgery, a stent device is often required to help the treatment and enhance the treatment effect. In neurovascular stent retriever's double-layer stent movable grid design, the stent grid can be more precisely adapted to the changes and complex conditions in the blood vessel through a changeable design, thereby improving the success rate of thrombectomy.
5. The device has the smallest radial support force, which can reduce the ratio of competing products by 15%, and greatly reduce the stimulation and damage of the vascular intima. When performing endovascular surgery, it is inevitable to cause a certain degree of damage to the inner wall of the blood vessel, but too much damage will cause greater damage to the treatment effect and the patient's body. The minimum radial support force of the Neurovascular Stent Retriever can effectively reduce the damage to the inner wall of the blood vessel and ensure the safety and effectiveness of the treatment.
6. The device full length visibility, which can directly observe the operation process in the blood vessel. When performing endovascular surgical treatment, it is very important to observe the real-time performance of the surgical process.
