Title: Prosthetic heart valve packaging and deployment system
Inventor: HODSHON FRED
IPC: B65D81/05
Filed: 2010-12-17
Abstract: Packaging for prosthetic heart valves including an assembly for securely retaining a heart valve within a jar and facilitating retrieval therefrom. The assembly includes a packaging sleeve that fits closely within the jar and has a clip structure for securing a valve holder. Contrary to previous designs, in one embodiment the valve holder is directed downward into the jar, and the valve is retained with an inflow end upward. The valve may have flexible leaflets, and a leaflet parting member on the end of the shaft extends through the leaflets and couples with the valve holder. The assembly of the packaging sleeve, valve, and holder can then be removed from the jar and a valve delivery tube connected with the holder, or to the leaflet parting member. The packaging sleeve may be bifurcated into two halves connected at a living hinge to facilitate removal from around the valve/holder subassembly. The packaging system facilitates attachment of the valve delivery tube for use in a quick-connect valve implant procedure.

Abstract: An ergonomically enhanced electric power tool is disclosed that incorporates a new type of user grip and control system. This grip and control system is housed in a substantially rigid control-housing sheath, which provides enhanced leverage and control over the drilling process while reducing stress on the users hand, wrist, and arm. The tool motor is disposed substantially in parallel with the users wrist, but on a different plane, and eliminates the traditional pistol type of power-tool grip. The control-housing sheath contains a grip-controller assembly that allows the user to control most major drill operations within the gauntlet-like control-housing sheath. The inventive concepts described can be applied to myriad hand-held power tools, and a detailed example for a power drill is provided.

Abstract: A device for measuring mild perceptual impairment of a human subject, comprises a generator of stimuli, a producer of responses to the stimuli, and a processor of the responses. Each stimuli has at least one parameter and includes a first-order dynamic stimulus and a second-order dynamic stimulus. The generator applies temporal frequency variations to at least one of the first-order and second-order dynamic stimuli.  Responses to the stimuli are indicative of a perception of the at least one parameter of each stimuli by the human subject and of a sensitivity of the human subject to the temporal frequency variations applied to at least one of first-order and second-order dynamic stimuli. The processor determines a perceptual signature which is a characteristic pattern of performance determined by measuring luminance sensitivity of the human subject to static and the first order dynamic stimuli and measuring contrast sensitivity of the human subject to static and the second order dynamic stimuli in view of determining if the human subject suffers from mild perceptual impairment. Determining perceptual signature is based on the temporal frequency variations applied to at least one of the first-order and second-order dynamic stimuli.
