20080200945 | DEVICE FOR OCCLUDING VASCULAR DEFECTS - Embodiments of the present invention provide devices and methods for treating abnormalities. For example, a device according to one embodiment includes a plurality of planes of occlusion, at least one plane of occlusion comprising a plurality of layers of occlusive material. The device is configured to at least partially occlude an abnormality. | 08-21-2008 |
20090062841 | DEVICE FOR OCCLUDING VASCULAR DEFECTS - A multi-layer occluder for treating a target site within the body is provided. The occluder may include first and second layers. For example, the first layer may include braided strands of metallic material, and the second layer may include braided strands of polymeric material. At least one of the first or second layers may be configured to facilitate thrombosis. | 03-05-2009 |
20090210047 | STENT GRAFT FOR REINFORCEMENT OF VASCULAR ABNORMALITIES AND ASSOCIATED METHOD - A stent graft for reinforcement of a vascular abnormalities and an associated method are provided. According to one embodiment, the stent graft includes a flexible tubular structure comprising a proximal end and a distal end and having an expanded heat set configuration. The tubular structure is configured to be constrained to a smaller diameter than the expanded heat set configuration, and the tubular structure is heat set such that at least a portion of the proximal and/or distal ends is configured to fold over on itself when unconstrained. | 08-20-2009 |
20090210048 | STENT/STENT GRAFT FOR REINFORCEMENT OF VASCULAR ABNORMALITIES AND ASSOCIATED METHOD - A stent/stent graft for reinforcement of vascular abnormalities and an associated method are provided. According to on embodiment, the stent/stent graft includes a flexible tubular structure comprising proximal and distal ends and having a heat set configuration. The tubular structure is configured to engage a lumen upstream and downstream of a vascular abnormality, such as an aneurysm, and a portion between the proximal and distal ends of the tubular structure is configured to engage the aneurysm. | 08-20-2009 |
20140135827 | MULTI-LAYER BRAIDED STRUCTURES FOR OCCLUDING VASCULAR DEFECTS - A collapsible medical device and associated methods of occluding an abnormal opening in, for example, a body organ, wherein the medical device is shaped from plural layers of a heat-treatable metal fabric. Each of the fabric layers is formed from a plurality of metal strands and the assembly is heat-treated within a mold in order to substantially set a desired shape of the device. By incorporating plural layers in the thus-formed medical device, the ability of the device to rapidly occlude an abnormal opening in a body organ is significantly improved. | 05-15-2014 |
20140261299 | INTERNAL COMBUSTION ENGINE - An internal combustion engine is described that includes an expansion cylinder adjacent to a first combustion cylinder (or power cylinder). Combustion gases from the first cylinder are directed to the expansion cylinder to act on the piston in the expansion cylinder. The expansion cylinder has a larger bore (i.e. larger diameter piston) and/or a longer stroke than the first cylinder. The longer stroke also results in a much larger crankshaft arm resulting in a significantly improved mechanical advantage (i.e. torque). In addition, the expansion cylinder includes a check valve that is designed to automatically open the expansion chamber to atmosphere if a negative pressure develops due to the varying amount of exhaust gases at different speeds. In one embodiment, two power cylinders can be connected to one expansion cylinder. | 09-18-2014 |
