Codman Neuro Launches 7-F Envoy DA XB Guiding Catheter

July 30, 2014—Codman Neuro, part of DePuy Synthes Companies of Johnson & Johnson, announced the launch of the Envoy DA XB distal access guiding catheter and the 7-F Envoy guiding catheter for neurovascular procedures. 

The announcement was made at the 11th annual meeting of the Society of NeuroInterventional Surgery in Colorado Springs, Colorado, where Codman Neuro is featuring the new device alongside its portfolio of neurovascular solutions, including microcoils, vascular reconstruction devices, and the full line of Envoy guiding catheters. 

According to the company, the Envoy DA XB device enables access to more distal anatomy and is designed to provide additional proximal support of the catheter when more stability is required. The new catheter is part of the Envoy DA guiding catheter family designed with a flexible distal segment for navigation to distal anatomy. It features a stainless steel end-to-end braided construction, a distal 10-cm hydrophilic coating, soft distal tip with a recessed metal marker, and the company’s Brite Tip technology for enhanced visibility. 

The 7-F Envoy is the company’s largest diameter guiding catheter, expanding upon the 6-F Envoy guiding catheters. The new catheters are offered in multiple shape configurations to navigate and treat different anatomy, noted Codman Neuro.

In the company’s press release, Ajit S. Puri, MD, commented, “Each of these new catheters provides reliable navigation and stability and offers distinct advantages during neurovascular procedures. The Envoy DA XB guiding catheters provide the reliable navigation associated with the standard Envoy guiding catheter, but in addition, offer distal catheter position in tortuous vascular segments. The 7-F Envoy guiding catheter has an inner lumen that accommodates and navigates multiple interventional devices without friction. It also has great support and optimal lumen for use with most carotid stents.” Dr. Puri is with the Division of Neurointerventional Surgery at University of Massachusetts Memorial Medical Center in Worcester, Massachusetts.

Gaurav Gupta, MD, stated, “The Envoy DA guiding catheter with its soft flexible distal segment and 0.071-inch inner lumen allows for ease of placement into the petrous segment, as well as additional inner lumen, for smooth advancement when using multiple devices such as a balloon and microcatheter. In addition, it works very well with intermediate catheters providing excellent stability as you place these devices in distal anatomy.” Dr. Gupta is Director of Cerebrovascular and Endovascular Neurosurgery at Rutgers Robert Wood Johnson Medical School in New Brunswick, New Jersey.
