Abstract: Disclosed herein are ultrasound systems and methods for sustained spatial attention. For example, an ultrasound system can include a console and an ultrasound probe. A display of the console can be configured to display ultrasound images and one or more still or moving images of a procedural field. The ultrasound probe can include a camera integrated into the ultrasound probe for recording the one-or-more still or moving images of the procedural field with a depth of field including a distal end of a probe head and a field of view including a spatial region about the probe head. With the one-or-more still or moving images displayed along with the ultrasound images, a clinician need not switch his or her spatial attention between spatial regions such as the procedural field and the display quite as frequently as with existing ultrasound systems, thereby sustaining spatial attention in one or more spatial regions.

Abstract: Disclosed herein are hands-free ultrasound probes, assemblies, systems, and methods. An ultrasound-probe assembly, for example, can include an ultrasound probe and a single-use pad coupled to a patient-facing side of the ultrasound probe. The ultrasound probe can include a probe body, a stabilizer extending from the probe body, a probe head including ultrasonic transducers in an array in a patient-facing portion of the probe body, and a needle-guide holder extending from the probe body. The stabilizer is configured for hands-free stabilization of the ultrasound probe when the ultrasound probe is placed on a patient with the pad interfacing a skin surface of the patient. An ultrasound system can include a console and the foregoing ultrasound-probe assembly. A method can include using the foregoing ultrasound system for hands-free ultrasound imaging while inserting a needle into an anatomical target to establish an insertion site for placement of a vascular access device.

Abstract: A pre-curved catheter includes a hub and an elastically deformable tubular body coupled to the hub. The elastically deformable tubular body can include a first body segment including a first body segment length including a lumen, a second body segment distal the first body segment, the second body segment including a second body segment length, and a first transitional body segment interposed between the first body segment and the second body segment. The first transitional body segment can include a selected first degree of curvature representing an angular change between a direction in an orientation of the first body segment and a direction in an orientation of the second body segment.

Abstract: A connector interface configured to enable component interconnection with a location sensor of a catheter placement system is disclosed. The catheter placement system is configured to assist a clinician in positioning a catheter in a desired location within a body of a patient. In one embodiment, the location sensor assembly comprises a location sensor body for temporary placement on a portion of the patient body, and a connector interface. The connector interface is configured to removably attach to the location sensor and provide a plurality of electrically conductive pathways between the location sensor and additional components of the catheter placement system to enable the additional components to operably connect with the location sensor. The connector interface further includes a first connector configured to operably connect with a second connector of one of the additional components of the catheter placement system through a drape interposed between the first and second connectors.

Abstract: A propulsion system and an aircraft that includes the propulsion system are provided. The propulsion system includes an engine and a cowling that surrounds at least a portion of the engine. The propulsion system also includes an inlet. The inlet includes a compression surface that is upstream and external to the cowling. The compression surface can slow air flow from a supersonic speed to a subsonic speed before the air flow enters the cowling.

Abstract: Embodiments of an inlet, aircraft, and propulsion system includes an inlet spike with a compression surface configured to decelerate air flow from supersonic speed to subsonic speed before the air flow enters a cowling throat and diffuser section of the propulsion system.
