Abstract: An endoprosthesis configured to shift between a collapsed configuration and an expanded configuration may include a tubular scaffold formed from a single filament knitted about a central longitudinal axis and defining a length from a proximal end to a distal end, the tubular scaffold including a plurality of rows of loops and a plurality of rows of rungs arranged around the central longitudinal axis in an alternating fashion; and a polymeric covering extending along the tubular scaffold. Each row of loops and each row of rungs extends longitudinally along the tubular scaffold between the proximal end and the distal end. The tubular scaffold includes a first cutout region extending along a majority of the length of the tubular scaffold and a second cutout region extending along a majority of the length of the tubular scaffold. The polymeric covering is uninterrupted along the first cutout region and the second cutout region.

Abstract: A valve assembly for a medical device that includes an enclosure to store an agent, a funnel coupled to the enclosure, and configured to receive the agent via an opening of the enclosure, and a valve fluidly coupled to the enclosure and the funnel. The valve is at least partially disposed between the enclosure and the funnel, and at least a portion of the agent is received on the valve. The valve is configured to move from a first position to a second position relative to the enclosure and the funnel to selectively release the agent from the enclosure into the funnel. In the first position, the valve is configured to close the opening and inhibit the agent from exiting the enclosure and entering the funnel. In the second position, the valve is configured to open the opening and release the agent from the enclosure for delivery into the funnel.

Abstract: Force magnitudes and/or directions may be determined objectively using orthodontic brackets having an elastomeric member which allows one portion of the bracket to be resiliently moveable relative to at least on other portion of the bracket. In a preferred embodiment, the brackets include a lower base member, an upper bracket member, and an elastomeric layer interposed between the lower base and upper bracket members. The orthodontic bracket is advantageously employed as part of a system whereby the orthodontic bracket includes a force indicator which distorts in response to relative movement between the at least one and other portions of the bracket to provide an indication of force applied to the bracket. An optical detector may be provided to optically detect the indicator and issue an output signal indicative of the relative resilient movement between the lower base and upper bracket members.

Abstract: Microreactors (10) and methods for generating hydrogen peroxide are disclosed. More specifically, microreactors (10) and methods are provided for the batchwise generation of hydrogen peroxide in which respective hydrogen and oxygen electrolysis chambers, and a hydrogen peroxide reaction chamber is fluid-connected to and positioned physically between, the electrolysis chambers. In specially preferred embodiments, the hydrogen peroxide microreactor (10) of the present invention will be in the form of a silicon chip reactor body having a pair of electrolysis channels (14-1, 14-2), reactant channel (14-3) positioned between the electrolysis channels, and at least one (preferably several) connector channel(s) (14-4) which fluid-connect(s) the pair of electrolysis channels (14-1, 14-2) with said reactant channel (14-3). A pair of electrodes (16-1, 16-2) is provided so that each is in operative association with a respective one of the electrolysis channels (14-1, 14-2).

Abstract: A skin cleansing and moisturizing device including a hand-held control wand that is detachably secured to a pad, one side of which is adapted to cleans the user's skin. A mechanical vibratory assembly is provided within the housing and imparts a vibratory motion to the pad. Additionally, a heat source is provided for heating the user's skin. The vibratory assembly may also apply suction to the skin through the pad.

Abstract: A device for cleansing teeth, including an arcuate housing defining an open top channel for placement over an arch of teeth and a plurality of cleansing components disposed within the channel for engaging and cleansing side and bottom surfaces of the teeth in the housing. The cleansing components include micro-fibrils that project from wall(s) of the housing or are defined on carriers suspended in a medium disposed in the channel.
