Patients suffering from Abdominal Aortic Aneurysms (AAA) are submitted to the innovative endoluminal stent graft procedure. Several medical centres throughout the USA are currently participating in Phase II for the Investigational Device Exemption (IDE) trial of the customized TALENT stent graft, developed by the World Medical Manufacturing Corporation. In order to offer the best conditions for the minimally invasive endovascular repair of aortic aneurysms, the Florida based company decided to close an agreement with Medical Media Systems to deliver the 3D Preview Surgery Planning Software. This valuable tool allows the clinical trial investigators to accurately plan the intervention, as well as to correctly size the endovascular stent grafts.
The Preview Surgery Planning Software constitutes in fact a 3D imaging service towards the surgeon. Computed Tomography (CT) scan data are used as an initial source to construct coloured 3D images of the patient's vascular anatomy. The physician can view the detailed structure from any possible angle, inside or outside the blood vessel. In this way, it is possible to precisely measure the blood vessel dimensions and to introduce virtual endograft simulations of the right size into the model, in order to make sure that the implants will accurately fit the patient's specific anatomy.
The imaging tool has been cleared by the Food and Drug Administration (FDA) and can equally be applied for plaque identification, thrombus and blood flow. In combination with the endoluminal stent grafts of the World Medical Manufacturing Corporation, which are designed to perfectly match with the individual patient's physical structure, the Preview software is bound to enhance the success of minimally invasive procedures to treat and cure aortic aneurysms. This enabling technology prevents surgeons from poor patient selection for this delicate type of intervention but also allows for post-operative analysis of patient/graft interaction, according to Vice President, Product Design and Marketing, Peter Robbie of Medical Media Systems.
Traditional imaging methods, such as CT scan and arteriography, often lead to artefacts and errors. Instead, the Preview software offers a computerized 3D model, especially developed for detailed endovascular AAA imaging. Dr. Hugh Beebe, Director of the Jobst Vascular Center and Professor of Surgery at the University of Michigan Medical School, states that the imaging tool substantially reduces the risk for the patient while being cost-effective at the same time. The medical centres, which are involved in the Phase II Study of the TALENT endoluminal stent graft, undoubtedly will benefit to the full from the Preview software support.
