Abstract: An endoscope includes a handle including a handle housing, an irrigation inlet port adapted to receive irrigation fluid, and an irrigation channel; and an insertion cord extending distally from the handle. The insertion cord includes an insertion tube; a bending section extending from the insertion tube; a distal tip extending from the bending section and including a tip housing; a camera at least partially enclosed in the tip housing; interstitial space within the insertion tube in fluid communication with the irrigation channel; and at least one interstitial flow opening in fluid communication with the interstitial space and adapted to discharge the irrigation fluid.

Abstract: A static mixer is disclosed. The static mixer comprises a housing (22) defining an internal mixing cavity (36) that longitudinally extends along a central axis between an inlet (38) and an outlet (40) and is adapted for axial flow of a fluid therethrough. The static mixer also comprises a mixing element (42) disposed within the mixing cavity (36). The mixing element (42) is configured to be free from an impingement surface oriented substantially perpendicular to a main direction of fluid flow through the internal mixing cavity (36). The mixing element (42) comprises an elongated mixing blade that is oriented longitudinally within the mixing cavity (36) and comprises a nose axially oriented toward the inlet (38). The static mixer may comprise a heat-exchanging jacket integrally formed with the housing (22). An additive manufacturing system comprising the static mixer, and methods of making and using the same, are also disclosed.

Abstract: A device including a rod with a tip and a channel formed in the tip. The device further includes a containment member including a first end and a second end opposite the first end. The second end is coupled to the tip, and the containment member includes an opening positioned at the first end. An expansion string and a compression string are coupled to the opening of the containment member. The expansion string extends through the channel in the tip.

Abstract: A method of forming a porous three-dimensional (3D) is disclosed. The method comprises (I) printing a first composition on a substrate (16) with the nozzle (12) of the apparatus (10) to form at least one first filament (14) comprising the first composition, (II) selectively controlling the distance and/or the speed such that the at least one first filament coils on the substrate to give a first layer on the substrate, the first layer comprising a coiled filament, optionally repeating steps I) and II) with independently selected composition(s) for any additional layer(s), and (III) exposing the layer(s) to a solidification condition. A porous three-dimensional (3D) article formed in accordance with the method is also disclosed.

Abstract: A method of forming a three-dimensional (3D) article is disclosed. The method comprises (I) printing a first composition (14) on a deformable substrate (18) at a volumetric flow rate with a 3D printer to forma deformable first filament (16) comprising the first composition on the deformable substrate. The method further comprises (II) controlling the volumetric flow rate to reduce a deformation force applied by a nozzle (12) of the 3D printer to the deformable substrate (18) and give a first layer comprising the deformable first filament (16) on the deformable substrate. In the method, (I) and (II) may optionally be repeated with independently selected composition(s) to form any additional deformable filament(s) and corresponding layer(s). Finally, the method comprises (III) exposing the layer(s) to a solidification condition. A 3D article formed in accordance with the method is also disclosed.

Abstract: A face mask that may be used for bag-mask ventilation, during the induction of general anesthesia for example, and allows for two-handed or ambidextrous use. The face mask includes a dome connected to a deformable rim, which forms an enclosed air space when the rim is pressed against a patient's face. The dome has a connection port and a contoured outer surface adjacent the connection port. The contoured outer surface includes contour features such as a pair of crossed composite recesses which may each receive a different one of a user's thumbs. The connection port is aligned with the patient's mouth when the mask is in use and an adapter may be included that attaches to the connection port and provides a ventilation port as well as an intubation port that is aligned with the mouth.
