A stent retriever is a medical device used to retrieve blood clots in the brain. This device has revolutionized the treatment of acute ischemic stroke by improving the chances of successful reperfusion in cases where traditional thrombolytic therapy was ineffective. The stent retriever industry has grown rapidly in recent years, with numerous manufacturers producing a variety of products to meet the needs of physicians and patients.
DredgerTM revascularization device is designed to be inserted through a catheter and guided to a site of occlusion in the cerebral vasculature. Once in position, the device is deployed to engage the clot and retrieve it from the vessel. These devices typically have a self-expanding cage or mesh that can be compactly packaged into a thin delivery tube. When deployed, the mesh expands to engage the clot and allow it to be withdrawn from the vessel.
There are several features to consider when choosing a stent retrieval. One important consideration is the size and shape of the device. Smaller, more flexible stentre trievers are preferred for accessing smaller cerebral vessels, while larger, more rigid devices may be necessary for removing larger or more resistant clots. Another important feature is the retriever's ability to conform to irregular or tortuous vasculature, which can make retrieval more challenging.
The DredgerTM revascularization device is a self-expanding stent retriever that is widely used by neurovascular specialists. It is a flexible, nitinol-based device that is available in a variety of sizes to accommodate different vessel diameters. It is designed to engage and retrieve clots in the middle cerebral artery and other large cerebral vessels.
