Cook launches high flow Cantata microcatheter and Alight guidewire


Cook has introduced two new solutions for targeting and treating challenging anatomy – the high-flow 0.027” ID Cantata microcatheter and the 0.016” Alight guidewire. 

Information on the Cook website states that both products can be shaped by hand, even the all-nitinol Alight microwire. The products also exhibit optimal tip torqueability and can be used as companion products or to complement the products physicians are already using.


The Cantata microcatheter is now available in a 2.9F size with a high-flow 0.027” ID that allows the delivery of a wider range of embolic agents. Complementing the existing line of superselective microcatheters (0.021” ID and 0.025” ID), the Cantata 2.9 is hand-shapeable and has a full-length braid for optimal torqueability.

Cantata offers a combination of support and torqueability to help interventional radiologists navigate tortuous anatomies, while minimising trauma with distal softness and microwire tracking, a press release from the company states.


Accepting .018 inch embolization coils, the Cantata allows coil delivery and can be used in combination with a wide range of emobolization products, including Cook’s MicroNester and Tornado Microcoils. Designed to be Lipiodol and dimethyl sulfoxide (DMSO) compatible, the Cantata microcatheter can be used in a range of procedures. The kink-resistant braided construction along the entire length of the shaft provides improved torque response and trackability for vessel selection while maintaining catheterization. With a hydrophilic coating designed to reduce surface friction, the 2.8 and the 2.5F catheter lines can achieve a flow rate as high as 3.5 mL/sec and 1.6 mL/sec, respectively. The five durometer zones, more than any other microcatheter, deliver a distinct yet seamless transition from the shaft to the soft, distal tip, reducing the risk of trauma.


Alight superselective guidewire

The Alight superselective guidewire is a companion for the microcatheter. This 0.016” all-nitinol wire has the ability to be shaped by hand to individual specifications and with no transition, there will be uninterrupted torque transmission. The distal polymer jacket provides good visibility under fluoroscopy, notes information on the Cook website.


Andrew Conder, senior global product manager, Embolic Therapies, Cook Medical, told Interventional News that one of the main advantages conferred by the Cantata 2.9F high-flow microcatheter is that it gives physicians the ability to achieve improved imaging of distal vasculature due to its higher injection rates.

The new all-nitinol Alight guidewire is the only guidewire on the market that combines the durability of nitinol with shapeability, he noted. “The tip of the Alight has the dual advantage of increased durability from nitinol combined with the ability to be shaped by the physician who can tailor the tip to suit that of the target vessel. We believe that the shapeability of the nitinol tip will be beneficial to physicians who had to previously sacrifice durability in long drawn out cases,” he said.

Conder noted that while the company had always had a broad embolization treatment portfolio, with Cantata and Alight it was looking to provide physicians with more access solutions.
