Patent number: 6511325Abstract: An aortic stent-graft model is provided. A hollow Y-frame is cast from polyurethane to form a core. After silicone aortic wall thickness and aneurysmal segments are applied to the contour of the core, the polyurethane core is removed to leave a hollow aortic model of silicone. Marking indicia are applied to the aortic model to effect selected dimensional measurements. The model can be utilized to calibrate the equipment of testing modalities such as contrast aortography (CA), spiral computed tomography (CT), magnetic resonance imaging (MRI), and intravascular ultrasonography (IVUS). Dimensional measurements from the marking indicia are compared to corresponding images of the model to detect any variation needed for calibration. An aortic stent-graft model can also be utilized to simulate introduction of a guidewire and catheter for deployment of a stent for repair of an abdominal aortic aneurysm (AAA).Type: GrantFiled: May 4, 1998Date of Patent: January 28, 2003Assignee: Advanced Research & Technology InstituteInventors: Stephen G.

Patent number: 6460342Abstract: A wave rotor detonation engine and method are provided. The wave rotor detonation engine includes a rotor rotatably mounted within a housing, an inlet port, an exhaust port, and an igniter for igniting the gases within the rotor. The rotor includes a plurality of circumferentially spaced longitudinally extending combustion chambers in which detonative combustion occurs. The inlet port has a plurality of separate inlet zones for supplying fuel and air mixtures to the inlet end of the rotor. The inlet zones are circumferentially spaced about the perimeter of the rotor so that the combustion chambers interact with these inlet zones sequentially. Each inlet zone is capable of introducing a different combustible mixture sequentially to a given combustion chamber as it rotates past the inlet zones. This results in the stratification of differing concentrations of combustible material within the combustion chambers which is particularly suited to create detonative combustion within the wave rotor.Type: GrantFiled: April 26, 2000Date of Patent: October 8, 2002Assignee: Advanced Research & Technology InstituteInventor: Mohamed Razi Nalim
