Abstract: The present disclosure relates generally to the field of medical devices and establishing fluid communication between body lumens. In particular, the present disclosure relates to devices and methods for establishing a controlled flow or access passage between body lumens. For example, a device may include an elongate tubular body defining a lumen along a length thereof. The elongate tubular body may have an unexpanded configuration and an expanded configuration. In the expanded configuration, a proximal portion of the elongate tubular body may expand into a proximal retention member and a distal portion of the elongate tubular body may expand into a distal retention member, leaving a cylindrical saddle region extending therebetween. The cylindrical saddle region may include a constricted portion configured to move between a first diameter configuration and a second diameter configuration larger than the first diameter configuration.

Abstract: A mandrel for forming a stent with a tapered profile and one or more anti-migration features includes a first stent shaping segment having a first diameter, a second stent shaping segment having a second diameter less than the first diameter and a tapered segment disposed therebetween. A third stent shaping segment is releasably securable to the second stent shaping segment and has a third diameter greater than the second diameter. One or more movable pins are outwardly extendable from corresponding apertures formed within the tapered segment. An actuation element is engagable with the first stent shaping segment and includes a tapered surface configured to engage the one or more movable pins and support the one or more movable pins extended from the corresponding apertures.

Abstract: Medical devices and methods for making and using a medical device are disclosed. An example medical device may include an implantable endoprosthesis. The implantable endoprosthesis may include a cylindrical body having a proximal end, a distal end, and an axial bonding region extending between the proximal end and the distal end. The cylindrical body may include one or more winding filaments and a plurality of discrete axial bonds disposed along the axial bonding region. The discrete axial bonds may secure together edge regions of the one or more winding filaments.

Abstract: Medical devices and methods are disclosed in the present application. In one illustrative example a tissue removal device may comprise an elongate shaft defining a lumen and having a proximal end and a distal end, wherein a proximal portion of the elongate shaft has a first diameter and a distal portion of the elongate shaft has a second diameter, and wherein the first diameter is less than the second diameter and an elongate member disposed at least partially within the elongate shaft, the elongate member having a proximal end and a distal end, the distal end of the elongate member comprising a cap. In some further embodiments, the elongate member may be axially translatable between a proximal position and a distal position, and the cap may form a closed receptacle with the distal portion of the elongate shaft when the elongate member is in the proximal position.

Abstract: A method for processing a biopotential signal includes detecting a pacing signal, and applying a dynamic filter on a pacing channel based on the detected pacing signal. A method for processing a biopotential signal includes detecting a pacing signal, and automatically obtaining a post-pacing interval based at least in part on the pacing signal.

Abstract: A valve includes a body having an interior and defining at least one inlet passageway and discharge passageway. The valve also includes a flow diverter disposed within the body between the inlet and discharge passageways to receive a fluid from the inlet passageway in an inlet direction. The diverter is adapted to discharge the fluid to at least one discharge passageway in a direction that differs from the inlet direction. The diverter is rotatable to vary the discharge direction. According to one embodiment, the discharge direction is substantially perpendicular to the inlet direction.

Abstract: A method and device for coating a medical device, such as a stent, including forming coating droplets using a mesh nebulizer and transporting the coating droplets to the medical device, for example through a converging chamber. The coating droplets may be accelerated to a speed sufficient to break the coating droplets into smaller droplets upon impact with the medical device. The mesh nebulizer may have a convex inlet side and may form a converging plume of coating droplets. The mesh nebulizer may have one or more groups of pores, the pores within each group may be subject to similar amplitudes of vibration. The coating material may be heated or cooled prior to nebulizing. The chamber may include baffles configured to allow only a predetermined size range of coating particles to pass.

Abstract: A vehicle thermal management system includes an exhaust gas cooler configured to receive exhaust gas from the engine and to cool the exhaust gas before it is recirculated back into the engine. A valve is located downstream from the exhaust gas cooler, and is operable to control the amount of exhaust gas passing through the exhaust gas cooler. Intake air mixes with the exhaust gas downstream from the first valve. The mixed gas is then cooled by a mixed gas cooler before it enters the engine intake manifold. A coolant is circulated through the mixed gas cooler and a heat exchanger. The mixed gas rejects heat to the coolant via the mixed gas cooler, and the coolant rejects heat to the ambient air via the heat exchanger.

Abstract: A vehicle thermal management system includes a temperature control fluid for controlling the temperature of at least a portion of a vehicle system. A pump is configured to pump the temperature control fluid through a heat exchanger to facilitate the transfer of heat between the temperature control fluid and ambient air. A fan is operable to move the ambient air across the heat exchanger to facilitate increased heat transfer. A control system is used to control operation of the pump and the fan. The control system is provided with operation data that includes optimized operating speeds for the pump and the fan to minimize power consumption, while maximizing heat transfer.
