Devices for Stroke Intervention: Review of Stent Retrievers and Balloon Guide Catheter
Globally, stroke is the second leading cause of death, killing nearly 6 million people each year. It is also the third leading cause of disability. In the United States, approximately 795,000 people suffer a stroke annually, and it is the leading cause of serious, long-term disability. In fact, in the U.S. a stroke occurs every 40 seconds, and every four minutes someone dies of a stroke.
We are bringing you more information regarding devices for stroke intervention:
TREVO XP PROVUE RETRIEVER
COVIDIEN’S SOLITAIRE™ FR REVASCULARIZATION DEVICE
CELLO BALLOON GUIDE CATHETER
TREVO® XP PROVUE RETRIEVER
Stryker's TREVO XP ProVue Retriever is a clot retriever for patients with ischemic stroke. Clinicians can view the retriever under fluoroscopic imaging while performing the clot retrieval.
According to the company, this allows for enhanced delivery and placement.
The retriever comes in a variety of sizes, including 3x20 mm, 4x20 mm, and 6x25 mm.
The TREVO XP ProVue Retriever received Prix Galien's "Best Medical Technology" award in 2014.
COVIDIEN’S SOLITAIRE™ FR REVASCULARIZATION DEVICE
The Solitaire FR Revascularization Device is an advancement in the endovascular treatment of acute ischemic stroke. The Solitaire device is used by interventional radiologists to recanalize the major cerebrovascular arteries that become occluded during a stroke leading to infarct of brain tissue distal to the thrombus.
“This new device is taking acute ischemic stroke care to a new level," said Dr. Vitor Mendes Pereira, Department Chairman at Geneva University Hospital in Geneva, Switzerland, and Principal Investigator for the Solitaire FR for Acute Ischemic Stroke study. "It clearly surpasses the first generation of clot-removing procedures, which were only moderately successful in reopening target arteries, and gives us a far superior tool for revascularization in stroke patients.”
Retrospective data collection from European sites experienced with the use of the Solitaire FR, when used as 1st choice device to treat patients with ischemic stroke and restore blood flow. Six European centers treated 141 patients for acute ischemic stroke using the Solitaire FR, as first intention device, in relation to their own clinical practice which involved the use of mechanical thrombectomy devices and pharmacologic agents from March 2009 to June 2010.
FlowGate Balloon Guide Catheter offers proximal flow control and a stable platform to facilitate the insertion and guidance of an intravascular catheter. It provides a balance of trackability and support with a large lumen and is indicated for use as a conduit for retrieval devices.
FlowGate is a new and unique BGC. It is easy to use, less stiff, and has improved trackability from bench testing that could possibly allow smoother delivery into the distal cervical and proximal petrous segment of the internal carotid artery (ICA). This feature allows it to possibly work more effectively and more completely, resulting in more reversal of flow given its more distal location.
The 8-F model has a 0.084-inch inner lumen allowing for more aggressive aspiration as well as concomitant use of intermediate large-bore aspiration catheters for salvage techniques as needed.
