Concentric Medical launches Dac 070, a new distal access catheter for neurovascular procedures


Concentric Medical announced the launch of the Dac 070 catheter. This is the fourth and largest diameter addition to the Dac family, making it the most complete family of distal access catheters commercially available.

The Dac catheter was the first in a new class of catheters known as distal access catheters. It is designed to help physicians navigate challenging anatomy in the brain and provide stability during neurovascular procedures.


Concentric Medical pioneered this new class of catheters with the introduction of the first Dac, the Dac 044, in August 2008. This device was originally designed to provide distal navigation and neurovascular stability during clot retrieval procedures in patients experiencing ischaemic stroke. With the launch of two additional sizes in 2009, the Dac 038 and the Dac 057, the Dac catheters quickly proved themselves as an invaluable tool in making many interventional neurovascular procedures easier.


The Dac 070 offers the stability of the original Dac 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, director of Neurosurgical Research and Stroke Services, University of Buffalo, New York, USA, 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, a neurointerventionalist at Shands Hospital in Gainsville, Florida, USA, 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, Dac provide the critical stability and support needed to make previously challenging cases easier and improve patient outcomes.”
