US FDA has given 510(k) regulatory clearance to Vascular Solutions Inc., a 
Minneapolis, Minnesota firm, to market the GuideLiner™ catheter. The device, designed to provide a coaxial guide extension and rapid exchange for coronary or peripheral interventions, comes in 6F, 7F, 8F (Freedom Fries) sizes and is delivered through standard guide catheters, hence it allows physicians to use “standard length guidewires, balloons or stents through an existing hemostatic valve,” according to the company.
From the press release:
The GuideLiner is a unique coaxial “mother and child” guide extension with rapid exchange convenience that provides back-up support and selective deep intubation in challenging coronary interventions. The GuideLiner catheter will be available in 6, 7 and 8 French sizes as part of Vascular Solutions’ specialty catheter product line. CE mark clearance of the GuideLiner was received and European sales and clinical uses commenced in October, with the U.S. launch of the GuideLiner catheter expected to commence in November through Vascular Solutions’ direct sales force.
Dr. Douglas Fraser, an Interventional cardiologist with Manchester Heart Centre in Manchester, United Kingdom, commented on his initial clinical experience with the GuideLiner: “Deep intubation of the Guideliner catheter within a soft 6F guide provides better backup support and is less traumatic than using stiff 7F and 8F guides that were previously required in complex disease. Furthermore, the soft and very flexible tip will often cross tortuous disease where a stent gets stuck, enabling delivery of stents and other equipment directly to the target lesion. The GuideLiner is as easy to insert as a standard rapid exchange balloon catheter and has quickly become a routine part of my angioplasty practice.”
Dr. Colm Hanratty, an interventional cardiologist at Belfast City Hospital in Belfast, Ireland, commented on one of his initial clinical uses of the GudieLiner: “In this patient, despite modification of the diseased segment and subsequent pre-dilatation, we could not track a 3.0 mm stent across the lesion due to significant friction in the proximal vessel. We then passed a 6F GuideLiner into the vessel and by removing the proximal resistance we could then deliver the 3.0 mm stent, followed by a 4.0 mm stent and post-dilatation with a 4.0 mm balloon. Deep intubation with the Guideliner facilitated delivery, allowed us to optimize stent apposition and also improved visualization of the vessel due to selective cannulation.”
