Specification
Dredger revascularization stent retriever is an innovative medical device used for intra-arterial thrombectomy, a procedure used to remove blood clots from the brain. The device is designed with a self-expanding stent and a retriever component made of material that can grasp and retrieve the clot from the blocked blood vessel. The Dredger's key feature is its ability to be used in diverse clinical scenarios due to its flexible and innovative design. The stent retriever is compatible with 0.021 inch microcatheters and can enable efficient removal of blood clots in different cerebral artery occlusion sites. Its meticulous and controlled grasping mechanism ensures that the clot is withdrawn intact to avoid fragmentation, reducing the risk of embolization.

The Dredger's key feature is its ability to be used in diverse clinical scenarios due to its flexible and innovative design. The stent retriever is compatible with 0.021 inch microcatheters and can enable efficient removal of blood clots in different cerebral artery occlusion sites. Its meticulous and controlled grasping mechanism ensures that the clot is withdrawn intact to avoid fragmentation, reducing the risk of embolization. It is indicated for acute ischemic stroke patients, particularly those with occlusions of major cerebral arteries such as the middle cerebral artery or the internal carotid artery. The device can also be used in patients exhibiting symptoms of large-vessel occlusion and can significantly benefit patients who are ineligible for intravenous thrombolysis. Dredger has a high procedural success rate, and the device's ability to restore blood flow to the brain swiftly has saved countless lives. When compared with traditional treatment approaches, the Revascularization Stent Retriever can achieve better functional outcomes due to its high efficacy rate in removing the clot, less invasive nature, and shorter procedural time.
Features &Advantages
1. The flexible tip is made of advanced materials such as nitinol, a shape-memory alloy that can be bent and twisted without losing its strength or shape. This flexibility allows the device to navigate smoothly through the tortuous pathways of the cerebral vasculature, avoiding sharp turns and tight bends that could cause injury to the vessel walls.By minimizing the risk of vascular injury, the flexible tip helps to ensure a safer and more effective treatment for patients. In addition, its flexibility also allows for greater control and precision during the procedure, enabling the clinician to manipulate the device with greater ease and accuracy.
2. The minimum radial support force is about 20% lower than that of its competitors, which means that it offers a more gentle and less invasive treatment option. The reduced force of the stent retriever is significant as it minimizes the stimulation and damage to the tunica intima. The tunica intima is the innermost layer of the blood vessels, and its damage can lead to inflammation, clot formation, and further complications. By reducing the force exerted on this layer, the stent retriever can reduce the risk of these complications, leading to a smoother recovery process.
3. The unique feature of this stent retriever is its active mesh, which is incorporated into the design of the stent. The mesh has the ability to change shape and conform to the blood vessel it is placed in. This allows the stent to capture and hold onto the blood clot, ensuring that it is removed from the patient’s brain. Moreover, the mesh is active during the entire retrieval process, meaning that it can adjust to the changing shape and size of the clot as it is being removed.
4. Protection umbrella-style net basket design enables the device to capture blood clots and prevent them from breaking off or escaping downstream. The retrieval basket is also designed with an expandable feature that allows it to cover a larger area of the vessel, which enhances its effectiveness.The stent retriever's other feature is its ability to collect and retrieve small emboli. Emboli are small clumps of debris that can break off from larger clots during retrieval and migrate downstream to cause blockages in other parts of the brain. The device's collection feature ensures that these emboli are captured, preventing any downstream complications.
