摘要: An occlusion device having laminated polyvinyl alcohol sheets for occluding a defect. The laminated polyvinyl alcohol sheets provide an increased tear strength to the sheets that allows the device to be fully retrievable through the same catheter used to deploy it. The laminated sheets are created by obtaining thin sheets of polyvinyl alcohol foam, arranging the sheets on one another, and applying heat and pressure to laminate the sheets together.

摘要: A method of forming a PVA foam structure for use in an occlusion device such that the PVA foam structure comprises non-thrombogenic properties. The method comprises forming a PVA gel and incorporating heparin into the PVA gel. The PVA foam structure is then treated with the PVA gel and heparin mixture, such as by soaking the PVA foam structure in the gel.

摘要: An RPM variation test for use in an engine analyzer system is used to test internal combustion engines. The engine analyzer individually disables cylinders and monitors instantaneous engine RPM, to generate an engine map. The engine analyzer performs an engine performance test upon the internal combustion engine. The engine map is used to map the results of the engine performance test. Using the present invention, an engine map is produced just prior to performing an engine performance test.

摘要: The present invention involves a toy vehicle which includes a body, at least three wheels, wheel support means and a suspension system. The wheel support means connects the body and the wheels in conjunction with the suspension system such that the body may be raised or lowered merely by pulling or pushing on the wheels away from or toward the underside of the body. The suspension system utilizes hollow plastic tubes which include a flexible zone with a plurality of circumferential corrugations which enable the tube to be stretched to sequential lengths until the corrugations assume a longitudinally spaced position. The toy vehicle of the present invention may have as part of its suspension system a single tube as described, or a plurality of tubes, such as one for each of the two front wheels or one for the front wheels and one for the back wheels, or any other combination which may be functionally possible. At least two tubes is preferred.

摘要: The present invention is an occlusion device having a centering arm network that self-centers across a defect and can be retrieved and redeployed in situ. A self centering system allows the center of the occlusion device to remain properly positioned within the defect, which increases the effectiveness of the occlusion device. The self centering system is comprised of a plurality of centering arms which define a flexible intermediate zone. In addition, the occlusion device of the present invention has a plurality of right arms connected to the plurality of centering arms which make it possible to retrieve and redeploy the occlusion device in situ.

摘要: A method and apparatus for conducting a visual acuity test are provided. The method includes displaying a visual acuity test on a display device (20) that is initiated by a controller (16) such as a handheld keypad controller (16), which is operatively associated with the computer-processing unit (12). The patient's eye is fixated using an eye fixation assessment on a display device during portions of the visual acuity test and is initiated by a controller such as a foot pedal controller (14), which is operatively associated with the CPU. Contrast sensitivity can also be evaluated on the display device by selectively altering the contrast of an image and background on the display device (20).

摘要: The present invention provides an occluder with a self centering system that keeps the occluder properly centered in a defect which allows the center of the occluder to remain properly positioned within the defect so that the left and right sides cover the entire defect which reduces the chance of blood shunting through the defect and increases the effectiveness of the occluder. The self centering system is comprised of a series of arms that provide tension to hold the right and left sides in place. The arms are shaped to provide a flexible intermediate zone comprising a left and a right conical shaped network, wherein each network extends from the right and left sides and narrows at the center section. The flexible intermediate zone centers the occluder and helps to hold it in place.
