The Gore DrySeal Sheath with Hydrophilic Coating was designed to minimize blood loss during the insertion of endovascular devices. Repairing thoracic aortic aneurysms (TAA) and abdominal aortic aneurysms (AAA) endovascularly has proven to be a successful alternative to open surgical repair, however physicians still strive to improve these procedures. The Gore DrySeal Sheath with Hydrophilic Coating was designed to minimize coating particulation and increase sheath lubricity, allowing for easier insertion and removal during endovascular repair procedures. It is comprised of a introcucer sheath complete with a Gore DrySeal Sheath valve attached, a dilator, and a 2.5 ml valve inflation syringe. The Gore DrySeal Sheath valve is pressurized to create a seal, minimizing blood loss while accommodating multiple catheters and wires. Intraprocedural manipulation is not necessary to maintain hemostasis. The sheath is available in profiles from 12 to 26 Fr in Fr increments.
