Abstract: A zinc-air charger having a case defining a plurality of pass core vents, and an internal case cavity; a plurality of zinc-air cells that are electrically coupled and disposed within the internal case cavity; a coupling plug configured to couple with and provide electrical power generated by the plurality of zinc-air cells to a device that is separate from the zinc-air charger; and a system configured to: output electrical power generated by the plurality of zinc-air cells to the device; identify a state of the plurality of zinc-air cells, determine, based at least in part on the identified state of the plurality of zinc-air cells, that one or more of the plurality of zinc-air cells are air-starved, and in response to determining that the one or more of the plurality of zinc-air cells are air-starved, generate a power cut-off for a period of time that ceases electrical power output to the device.

Abstract: A modular wound therapy training device, system, and method of use for the device are provided. The device may include a support tray, an elastic insert, a base within the elastic insert, a recess within the base, a conformable polymer, a dressing and a negative pressure source. The recess may be circumferentially smaller than the base and the conformable polymer may be sized to fit within the recess. The device is preferably sized and shaped to form a system when aligned and assembled with duplicates of the device. A method is provided to apply negative pressure and installation therapy when a negative pressure source is activated through a protective dressing.

Abstract: Provided herein are compositions that are useful for attracting fish, conch, crustaceans, or any combination thereof. Also provided herein are processes of preparing the compositions, methods of using the compositions for improving the biosecurity of an environment, and methods of using the composition for attracting fish, conch, crustaceans, or any combination thereof.

Abstract: A storage container includes a frame body with insulated walls at least partially enclosing a cavity, a door member connected to the frame body to selectively cover an opening in the frame body to the cavity, a cooling system connected to the frame body to maintain a temperature in the cavity at or below a first temperature threshold, and a heating system connected to the frame body to maintain the temperature in the cavity at or above a second, lower temperature threshold.

Abstract: A system for canceling acoustic feedback includes an input for receiving a digital audio signal and a processor configured to detect acoustic feedback signal in the digital audio signal and to determine the frequency of the feedback signal The system also includes a plurality of bandpass filters for attenuating the feedback signal. The processor is further configured to: select a bandpass filter from among the plurality of bandpass filters. The selected bandpass filter comprises a response characteristic that attenuates parts of the signal at the frequency of acoustic feedback signal.

Abstract: The present invention provides a medical system comprising an elongated medical device having a longitudinal lumen, such as a catheter or a needle, and a stylet configured to be inserted into and subsequently removed from the longitudinal lumen. The stylet is configured to have at least one indicator that indicates that the distal end of the stylet is about to exit the lumen as the stylet is being withdrawn during use. Each indicator alerts the user that the stylet is almost completely withdrawn from the lumen such that the user may take proper precautions and prevent the stylet from inadvertently and uncontrollably exiting the lumen. Each indicator may be located in the proximity of the distal end of the stylet and present either a visual, physical, or audible indication. Additionally, the present invention provides a method that indicates the longitudinal position of a stylet relative to an elongated medical device.

Abstract: A stent introducer apparatus includes a handle having a housing and a rotatable reel. An inner stent carrier having a proximal end and a distal end is provided, with the proximal end being connected to the housing of the handle. An outer sheath movably disposed about the inner stent carrier and having a proximal end and a distal end is provided, with the proximal end being connected to the reel of the handle. Rotation of the reel relative to the housing peels the outer sheath away from the inner stent carrier so as to move the outer sheath proximally relative to the inner stent carrier, thereby exposing the distal end of the inner stent carrier. The inner stent carrier has a stent carrying portion at its distal end to carry a stent that is deployed when the distal end of the inner stent carrier is exposed.

Abstract: A stent delivery system for positioning a first and second stent the first and second branch lumens of a bifurcation. The stent delivery system includes stent introducers and a sheath or catheter having a frangible wall. A method of delivering stents to anatomies such as bifurcated ducts or vessels.

Abstract: A stent delivery system and method for positioning a first and second stent in the main lumen and the first and second branch lumens of a bifurcation.

Abstract: A method and apparatus for introducing a first elongate medical device and short wire guide that are coupled together into a work site and remotely disconnecting them within the work site such that a secondary device comprising a catheter member can be introduced over the wire guide to the work site, and/or a second wire guide can be introduced to the work site via a passageway of the primary access device. A system of indicia, such as radiopaque or viewable markers, permits the operator to monitor the relative alignment of the devices within the work site to determine when uncoupling has occurred. In one example of the method, a wire guide and primary access device (e.g., a sphincterotome) is coupled to the wire guide and introduced via a duodenoscope into the biliary system. After performing a first medical operation, the devices are uncoupled with the wire guide being left within the biliary system such that a secondary access device, such as a balloon, biopsy device, stent delivery catheter, dilator, etc.
