FDA Reviews Catheter Use Differences

Share

In a letter to healthcare providers, CDRH says it is aware of marketing materials and recently published literature that imply a new intended use for some neurovascular guide catheters for neurovascular thrombosis removal in patients with acute ischemic stroke. The letter says that FDA has not cleared neurovascular guide catheters for that indication.

“Healthcare providers are encouraged to carefully consider the information provided [in the letter] explaining the FDA cleared intended use when reading marketing materials and literature provided for guide catheters,” the letter says. “It is also important for healthcare providers to be aware of and consider the differences in device design between cleared neurovascular guide catheters and neurovascular thrombus retrieval catheters and the potential implications those differences may have during certain uses, especially in the more distal regions of the neurovasculature.”

A chart in the letter gives the product code, indication, and performance data for thrombus retrieval catheters and guide catheters. It notes that the two types may be designed with different features, such as length, diameter, and variations in material stiffness distally and proximally. “Use of neurovascular guide catheters for thrombus removal may affect the safety and performance, which could result in device failure and/or serious adverse events such as vessel damage, perforation, or dissection when used in the most distal regions of the neurovasculature,” it cautions.
