Jotec has announced it will launch an updated version of its E-vita abdominal stent graft system. According to Jotec, the new system, E-vita abdominal XT, represents latest catheter technology with excellent properties. “The new delivery system and the previously optimised spring configuration of the stent graft in 2011 form a completely enhanced stent graft system,” the company stated in a press release.
E-vita abdominal XT is indicated for endovascular treatment of abdominal aortic aneurysms which may also affect the iliac arteries. The stent graft system can be used if the diameter of the aortic neck ranges from 19 to 29mm and the diameter of the iliac artery ranges from 11 to 23mm.
According to Jotec, the E-vita abdominal XT device offers a new designed multifunctional wire-reinforced catheter with high flexibility in the proximal part and outstanding pushability in the distal portion without any risk of kinking. The hydrophilic coating significantly reduces friction during insertion and passage of the arterial vessel system. The delivery system offers a small crossing catheter profile starting at 16F for the extensions and 20F for the main body. The system kept the patented Squeeze-to-Release deployment mechanism for stepwise or continuous release of the stent graft while focusing on precise positioning and safe handling.
The modular stent graft consists of four different modules: main body, contralateral leg, iliac and aortic extension. The updated spring configuration combines smaller spring height and increased spring distance, which leads to improved flexibility especially in the legs. Furthermore, the introduction of the special E-marker on the short leg of the main body helps to localise the short leg and supports canalisation. The main body is available in diameters from 24 to 34mm, trunk length of 50 and 70mm and a total covered length of 150 and 170mm. The distal diameter of the ipsilateral leg varies from 12 to 22mm and for the contralateral leg from 12 to 24mm. E-vita abdominal XT is expected to receive the CE mark in November 2012 and will be immediately introduced into the market.
