Concentric Medical Releases Larger Clot Removal Catheter

July 26, 2011 — Concentric Medical Inc. has launched the DAC 070 Catheter, the fourth and largest diameter addition to its distal access catheter (DAC) family to aid clot removal in ischemic stroke patients. 

The DAC catheter was the first in a new class of catheters known as distal access catheters. It was designed to help physicians navigate challenging anatomy in the brain and provide stability during neurovascular procedures. Stability and ease of navigation are important to keeping interventional procedures both safe and short.

Concentric Medical pioneered this new class with the introduction of the first DAC, the DAC 044, in August 2008. It was originally designed to provide distal navigation and neurovascular stability during clot retrieval procedures in patients experiencing ischemic stroke.

With the launch of two additional sizes in 2009, the DAC 038 and the DAC 057, they help make many interventional neurovascular procedures easier.

With the launch of the DAC 070, Concentric Medical now offers a broad selection of sizes to support a wide variety of neurovascular procedures. The new product offers the stability of the original catheters with the added benefit of a larger lumen through which physicians can deliver multiple therapeutic devices.

After his initial experience with the new DAC 070, Adnan Siddiqui, M.D., director of neurosurgical research and stroke services at the University of Buffalo in Buffalo, N.Y., said, "The DAC 070 is a nice addition to the family. Not only does it provide the key design benefits of a smaller DAC, but the larger lumen allows for the introduction of multiple devices while maintaining good lumen integrity. The balance of stability and flexibility make this catheter uniquely helpful in a variety of cases including some in the venous vasculature."

Following his initial cases with the DAC 070, J. Mocco, M.D., a neurointerventionalist at Shands Hospital in Gainesville, Fla., said, "The DAC family of catheters represents a unique and powerful tool for neurovascular procedures. The full array of sizes and lengths make this technology helpful in many clinical situations. In my experience, DACs provide the critical stability and support needed to make previously challenging cases easier and improve patient outcomes."
