The DredgerTM stent retrieval device is intended to restore blood flow and retrieve clots by removing thrombus from a large intracranial vessel for patients experiencing acute ischemic stroke symptom onset.
The DredgerTM stent retriever device is used to remove blood clots from the cerebral arteries of patients who have suffered an acute ischemic stroke. An ischemic stroke is caused by the blockage of a blood vessel in the brain, leading to a sudden interruption of the blood supply. This can cause significant damage to the brain, resulting in motor, cognitive, and sensory deficits. The intracranial stent retriever is designed to restore blood flow to the affected area of the brain, thereby reducing the risk of permanent disability or death. It is made up of several components. The first is a flexible catheter, which is inserted into an artery in the groin and guided up to the blocked vessel in the brain. Once the catheter is in place, a stent retrieval is deployed. This is a tiny, expandable mesh tube that can be used to capture and remove the clot.
Features & Advantages
1. Non-traumatic guide wire tip is particularly essential as it reduces the chances of traumatic injury during the device's introduction into the targeted area.
2. A larger push rod provides more supporting force, which enables medical practitioners to achieve more efficient clot retrieval during the procedure.
3. Double-layered structure with a movable mesh enables the device to move more flexibly, significantly reducing the chance of complications in the targeted area. This feature also helps to increase the stability of the device during the procedure.
4. Minimum radial support force reduces the risk of vessel wall injury during the procedure. This feature makes the device safer during the operation and consequently reduces the chances of complications that may arise due to vessel wall injury.
5. Front-end protective umbrella-like mesh design helps to prevent the detachment of debris during the extraction process.
6. Full process imaging capability not only allows the medical practitioners performing the procedure to have a clear view of the entire process of the device's deploymen, but it also enables medical practitioners to monitor the procedure in real-time.
