The DredgerTM Endovascular Clot Retrieval Devices is used to remove the thrombus blocked in the intracranial large arteries within 8 hours of the onset of ischemic stroke to achieve the therapeutic purpose of restoring blood flow, including the M1 and M2 segments of the internal carotid artery and middle cerebral artery.
The DredgerTM Endovascular Clot Retrieval Devices, also known as mechanical thrombectomy devices, are a revolutionary treatment option for patients suffering from an ischemic stroke. These devices are designed to remove clots from blood vessels in the brain, minimizing damage to brain tissue, and ultimately reducing the impact of the stroke. The use of endovascular clot retrieval devices is recommended for patients suffering from an acute ischemic stroke caused by an occluded large artery within six hours of symptom onset. Typically, patients with large artery occlusion have poor outcomes and are at a high risk of permanent disability or death. However, through the use of these devices, patients have a higher likelihood of a successful outcome and recovery. Endovascular clot retrieval devices are also useful for patients who are not eligible for intravenous thrombolysis. Intravenous thrombolysis is a routine procedure that involves the injection of a clot-busting medication into the bloodstream, but it can only be used within a short window of time after symptom onset. For patients who do not meet the criteria for intravenous thrombolysis or have not responded to it, endovascular clot retrieval devices offer an alternative solution, allowing the physician to safely remove the blood clot and restore blood flow to the affected area, reducing further neurological damage. Furthermore, these devices are used to manage acute stroke patients with extensive collateral circulation, in whom intravenous thrombolysis may not be necessary. It is a crucial tool for patients with a high risk of thrombolysis-associated complications such as bleeding.
Features & Advantages
1. The soft atraumatic distal tip is a key feature that makes endovascular clot retrieval devices effective and safe. It ensures that the device can be used without causing harm, allowing doctors to effectively remove clots and restore blood flow to the affected area
2. Large push wire allows for improved control and precision during the procedure. It allows the surgeon to push the device through the problematic blood vessel with greater ease, reducing the risk of damage to surrounding tissues and organs.
3. The truck net is a unique component to ensure effectively remove clots from the bloodstream. It is specially designed to trap and hold clots as they are pulled out of the body, preventing them from breaking apart and causing further damage to the vessel walls.
4. The varied cell design of this device enables it to efficiently clamp the blood clots, ensuring a secure grip on the blockage. This design also allows for better engagement with different types of blood clots, improving the overall efficacy of the retrieval procedure.
5. Lowest radial outward force means they have a gentle touch that minimizes damage to the artery walls. This is especially important during the removal process, when the device must be careful not to damage the delicate intima that lines the inside of the blood vessels.
6. Closed ring design allows for precise matching with the profile of the patient’s blood vessels. This means that the device can be accurately positioned to target the clot and remove it effectively, without causing damage to the surrounding tissue.
