Dredger Thrombectomy Stent Retriever is a specialized medical device used in the treatment of ischemic strokes caused by blood clots in the cerebral arteries. These devices are designed to remove the blood clot from the affected artery, thus restoring blood flow to the brain and preventing further damage. One particular type of thrombectomy stent retriever is the dual-layered stent, which has proven to be effective in treating a variety of ischemic stroke cases.

The dual-layered DredgerTM thrombectomy stent retriever is a uniquely designed device that consists of two layers. The outer layer is made of tightly packed metal wires that form a cage-like structure when deployed in the affected artery. The inner layer is a mesh of finer wires that are tightly woven together to create a strainer-like structure. When the device is deployed in the affected artery, the outer layer expands to capture the blood clot, while the inner layer filters out any debris or small clots that may have broken off during the thrombectomy procedure. DredgerTM thrombectomy stent retriever has a unique design that enables it to cover a large surface area while simultaneously providing high radial force. The stent retriever layers work together to ensure the clot is removed safely from the blocked artery, reducing the risk of damage to the vessel wall. One of the key advantages of stent retriever device is its excellent visibility. This is especially important when performing minimally invasive procedures, as it ensures that the device is positioned accurately and increases the likelihood of success. Another advantage of the stent retrieval device is its unique stent design. It utilizes a variable mesh design that allows for greater adaptability to the contours and dimensions of the cerebral vasculature. This ensures maximum coverage of the occlusion site and provides excellent radial force for effective clot retrieval.
