Publication number: 20150151090Abstract: The present application describes a coaxial guide coil catheter device to be placed inside of a standard cardiovascular guide catheter for facilitating extra support in the coronary artery when advancing interventional cardiology devices such as balloon catheters and stent delivery systems. This device is passed through the main lumen of a standard guide catheter so that the tip of the coaxial guide coil device is extended past the tip of the guide catheter and into the coronary artery. The proximal portion of the coaxial guide coil will remain within the guide catheter. The device improves the ability of the guide catheter to remain seated in the coronary ostium during interventional procedures.Type: ApplicationFiled: June 10, 2013Publication date: June 4, 2015Inventors: Gregg Stuart Sutton, Jeffrey M. Welch, Karl V. Ganske

Patent number: 8292850Abstract: A coaxial guide catheter to be passed through guide catheter having a first lumen, for use with interventional cardiology devices that are insertable into a branch artery that branches off from a main artery. The coaxial guide catheter is extended through the lumen of the guide catheter and beyond the distal end of the guide catheter and inserted into the branch artery. The device assists in resisting axial and shear forces exerted by an interventional cardiology device passed through the second lumen and beyond the flexible distal tip portion that would otherwise tend to dislodge the guide catheter from the branch artery.Type: GrantFiled: January 26, 2012Date of Patent: October 23, 2012Assignee: Vascular Solutions, Inc.Inventors: Howard Root, Gregg Sutton, Jeffrey M Welch, Jason M Garrity
