TU068

The stent graft comes in two nominal lengths (100mm or 150mm) with different inner vessel (ID) and outside vessel OD graft diameters (mm). There are 40 catalogue items with the above combinations Overall length: 340-390 mm. Vascular graft length 240 mm; Stent graft length 100-150 mm; Stent graft diameter 20-40 mm; Collar width 12 mm;

Thoraflex™ Hybrid device is a woven polyester prosthesis, with the addition of nitinol ring stents. The device is specifically designed for the treatment of aneurysm and/or dissection in the ascending thoracic aorta, aortic arch and descending thoracic aorta. Branches are provided to accommodate reconstruction of the major aortic branch vessels and intra-operative attachment of a perfusion cannula during cardio-pulmonary bypass where antegrade perfusion techniques are employed. The stented section of the graft enables treatment of the diseased descending thoracic aorta in a single-stage procedure without the need to anastamose a stented and unstented prostheses together. Thoraflex Hybrid™ device has been impregnated with an absorbable protein. The aim of the impregnation is to provide a polyester vascular prosthesis which does not require pre-clotting. The protein is a bovine gelatin which has been cross-linked to a set level to control its rate of removal. It serves in place of fibrin, which seals the polyester prosthesis during normal pre-clotting. The gelatin is hydrolyzed within approximately 14 days and is replaced by normal tissue incorporation. Gelatin has been chosen as it is a non-toxic protein, a fact which is reflected by its extensive use as a safe plasma expander.
