Cook Medical introduces a new thoracic aortic aneurysm stent

Release date: 2009-05-12

Cook Medical has announced the launch of its new Zenith TX2 stent with Pro-Form technology, which provides better controllability for interventional treatment of thoracic aortic aneurysm (TAA), thereby enhancing the clinical outcome of endovascular repair in patients with TAA. Efficacy.

Currently, the technology has been approved by CE Mark (European Standard Certification). This innovation provides unprecedented safety for TAA endovascular repair, and even includes stent-graft placement for extremely narrow aortic arches that clinicians consider to be quite tricky.

In China, there are approximately 100,000 patients with thoracic aortic aneurysms. With the aging of today's population and changes in people's lifestyles, especially diets, the incidence of arteriosclerosis and hypertension in China is higher, and the incidence of aneurysms is on the rise. Because most aneurysms have no symptoms before rupture, and current surgical techniques are immature, less than one in a thousand have received effective treatment.

In approximately 25% of all TAA patients, the inverted U-shaped aortic arch is extremely narrow. Many of the currently available endoluminal stents are not too rigid, or the radial bracing force is too small to fit the internal curved surface of the narrow aortic arch, so that the aneurysm cannot be completely closed. Therefore, in the past, surgeons had to use complicated methods to reduce the risk of endoleaks and ruptures after aneurysm repair, but this also made the repair surgery more complicated and lengthy.

Ralf Kolvenbach, professor at the Augusta Hospital in Germany, the Catholic Hospital in Düsseldorf, and the University of Düsseldorf, was the first vascular surgeon to use the TX2 Pro-Form for TAA repair surgery. He said: "With the TX2 Pro-Form, I The thoracic aortic aneurysm can be closed in the shortest possible time with maximum controllability. The new stent delivery system helps me achieve precise placement of the stent and perfectly fit the vessel wall. With the help of this stent graft system, the chest The safety of aortic aneurysm repair will reach a new height."

Mr. Phil Nowell, global head of Cook's Medical Aortic Interventions Division, said that our goal is to provide the industry's best-performing, highest-controllable technology to surgeons. At present, many doctors have discovered that when the stent is placed in the narrow aortic arch, it forms a 'birdbill' type groove at the bottom of the aortic arch. We believe that the improved technology introduced this time can solve this problem very well. Shanghai Medical Device Industry Association
