Gore DrySeal Sheath used in first patient to aid in minimally invasive treatment of abdominal aortic aneurysms


Revolutionary device delivers consistent performance, better control, and minimised blood loss during endovascular procedure.

Gore has recently announced the first patient case involving the revolutionary Gore DrySeal Sheath. The sheath aids in minimally invasive treatment for patients with abdominal aortic aneurysms (AAA) with the Gore Excluder AAA endoprosthesis and thoracic aortic aneurysms (TAA) with the Gore TAG thoracic endoprosthesis. The successful procedure was performed by Alan Lumsden, chairman of the Department of Cardiovascular Surgery, The Methodist Hospital in Houston, USA, during a Gore-sponsored Acute Symptomatic AAA Workshop conducted in The Methodist DeBakey Heart and Vascular Center.

Gore received FDA clearance in April 2010 to market the Gore DrySeal Sheath, which comprises the innovative haemostatic Gore DrySeal Valve attached to the introducer sheath. The Gore DrySeal Valve is truly unique in that it is pressurised to create a seal, thereby minimising blood loss and accommodating multiple wires and catheters simultaneously. The valve consists of a silicone outer tube and an inner film tube that create an effective haemostatic seal that easily adapts to the profiles of the inserted devices. The device is available in profiles from 12 to 26Fr, in 2Fr increments, and has a working length of 28cm.

According to Lumsden, “The ability of the Gore DrySeal Valve to accommodate multiple devices during difficult procedures with minimal blood loss keeps the operating field free from excess blood, while helping to prevent unnecessary blood loss to the patient. The Gore DrySeal Sheath requires no intra-procedural manipulation of the valve, delivering consistent performance throughout the procedure and allowing the physician to maintain focus on the endovascular procedure – without being concerned about blood loss at the patient access site.”

Gore Aortic business leader David Abeyta added, “This latest addition to Gore’s portfolio of world-class endovascular devices and accessory products minimises patient blood loss during procedures with endovascular devices, such as the Gore Excluder AAA endoprosthesis.”
