Abstract: A wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an external infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the volume sensor assembly. The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system further includes a first valve assembly configured to selectively isolate the pump assembly from the reservoir, and a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set.

Abstract: The system isolates a clot using a proximal obstruction device, such as a balloon, to stop blood flow. An expandable device is advanced through the clot and is expanded to disrupt the clot from the vessel walls. The expandable device may include the use of tines, a balloon, negative pressure, adhesives, or jet spray to disrupt and dislodge the clot.

Abstract: A patch-sized fluid delivery device may include a reusable portion and a disposable portion. The disposable portion may include components that come into contact with the fluid, while the reusable portion may include only components that do not come into contact with the fluid. Redundant systems, such as redundant controllers, power sources, motor actuators, and alarms, may be provided. Alternatively or additionally, certain components can be multi-functional, such a microphones and loudspeakers that may be used for both acoustic volume sensing and for other functions and a coil that may be used as both an inductive coupler for a battery recharger and an antenna for a wireless transceiver. Various types of network interfaces may be provided in order to allow for remote control and monitoring of the device.

Abstract: Some aspects of the disclosure relate to a system and methods for creating a viewing impression that can comprise selecting a video frame from a content item based on interest or value in the video frame. Another version of the content, such as a trick file, can be created by inserting one or more copies of the video frame, for example, adjacent to one another.

Abstract: A computer-implemented method may be used for semantic navigation of content. The method may include determining a first content complexity level for a user, and presenting a first content to a user device operated by the user. The first content may be presented at the first content complexity level of the user. Additionally, the method may include receiving a navigation command from the user on a portion of the first content via the user device; and determining a second content at a second content complexity level based on the navigation command. The second content may convey the same information as the first content. Additionally, the method may include replacing the first content with the second content on the user device. The second content may be presented at the second content complexity level, and the second content complexity level may be different than the first content complexity level.

The wearable infusion pump assembly also includes a releasable engagement assembly configured to allow the reusable housing assembly to releasably engage the disposable housing assembly. A switch assembly of the wearable infusion pump assembly is configured to effectuate a functionality of the infusion pump assembly.

Abstract: An occlusion device with particular utility in occlusion of left atrial appendages is described. The occlusion device utilizes an inflatable balloon comprising a proximal portion to inflate with an inflation fluid delivered by an outer catheter body and conform to a shape of the left atrial appendage and a distal portion to fill with an adhesive delivered by an inner catheter body. The distal portion of the inflatable balloon sticks to the tissue wall of the left atrial appendage. The outer catheter body is configured to position the inner catheter body inside the outer catheter body.

Abstract: A method of dispensing a therapeutic fluid from a line includes providing an inlet line connectable to an upstream fluid source. The inlet line is in downstream fluid communication with a pumping chamber. The pumping chamber has a pump outlet. The method also includes actuating a force application assembly so as to restrict retrograde flow of fluid through the inlet while pressurizing the pumping chamber to urge flow through the pump outlet. A corresponding system employs the method.

Abstract: A composite polishing strand has a polishing strip for polishing a dental restoration, such as a filling, and may incorporate a floss leader coupled to a polishing strip. The floss leader may be snapped down between teeth and the polishing strip may then be pulled into the interproximal contact area for polishing a dental restoration. A composite polishing strip may also include a threader having an insert end that can be inserted into an interproximal contact area, such as an interproximal subjacent contact area, and pushed through to the opposing side. The threader may then be pulled to locate the polishing strip in the interproximal contact area for polishing the dental restoration. The composite polishing strip having both a threader and floss leader enables two different methods of locating the polishing strip in the interproximal contact area and therefore is very versatile.

Abstract: System and methods of delivering adhesive material are described for occluding target locations within a patient. The systems include a catheter configured to deliver adhesive to a target location and one or more of a light source to harden the adhesive, a retention structure to contain the adhesive prior to curing, a balloon to occupy a target location, and an open cell foam plug to occupy a target location.

Abstract: A computer implemented continuous dual auction system consisting of a computer, server, and a process for creating a real-time, or substantially real-time, online marketplace for the sale of goods and services. The system allows a buyer to define parameters of one or more items that the buyer wishes to purchase and place a bid on all of the items that satisfy those parameters. The system automatically takes any fees to be paid by the buyer and the seller into account for a buyer's bid and a seller's offer. The system may be accessed via a web browser or a remote application.
