Abstract: Embodiments of the present disclosure are directed to apparatuses, devices, and methods for secure connections between tubular structures. In one implementation, a first tube constructed of nitinol may have windows formed on an end thereof. A second tube constructed of stainless steel tube may be inserted within the first tube, and the windows may be filled with adhesive or solder. The adhesive or solder may bond with the first tube, forming connection pins which secure the tubes together. In some embodiments, the connected tubes may form an endoscopic needle. The nitinol portion of the needle may be sufficiently flexible for positioning within the bending section of an endoscope without deformation. The stainless steel portion of the needle may render the needle significantly less expensive than prior needles constructed solely of nitinol.

Abstract: An infusion set includes a base (221) and a flexible catheter (242) movable from a first catheter position disposed substantially entirely within the base (221) to a second catheter position in which a free end of the catheter (242) is disposed externally of the base (221). An introducer needle (234) is located within the catheter (242) and is movable between a first introducer needle position disposed substantially entirely within the base (221) and a second introducer needle position in which a free end of the introducer needle (234) is disposed externally of the base (221). A spring (281) is activated to move the catheter (242) from the first to the second catheter position and the introducer needle (234) from the first to the second introducer needle position to facilitate insertion of the catheter (242).

Abstract: A system to detect a position of a cannula may include a cannula, which may include a distal tip and an inner lumen. Also, the system may include an optical fiber, which may be disposed within the inner lumen of the cannula and may include a first end, a second end, and a U-shaped portion disposed between the first end and the second end. The U-shaped portion may be at least proximate the distal tip. Further, the system may include a light emitter, which may be coupled with the first end of the optical fiber, and a light receiver, which may be coupled with the second end of the optical fiber. Moreover, the system may include an electronic processor. The electronic processor may be coupled with the light receiver and configured to detect a decrease in an intensity of light received at the light receiver.

Abstract: Embodiments of the disclosure include an endoscope tip assembly for use on an endoscope, during procedures. The endoscope tip assembly may include a base, configured to receive an endoscope tip configured to not disengage from the endoscope tip during a procedure. The endoscope tip assembly may also include a plurality of struts, connected by a webbing, that may fold flat during insertion, and may assume a balloon-like shape during withdrawal.

Abstract: Embodiments of the disclosure may include an endoscope floor stand. In accordance with one embodiment, an endoscope floor stand may include a base and an adjustable body. The body may include at least a first elongated structure having a first end and a second end, wherein the first end is connected to the base. The body may also include at least a second elongated structure slideably moveable relative to the first elongated structure to adjust a height of the endoscope floor stand, and the second elongated structure may be suspended above the base. The stand may also include a ball joint, wherein at least a portion of the ball joint is configured to removably couple to an end of the body located opposite the base. The ball joint may also include a holder extending from the ball joint and dimensioned to receive an endoscope.

Abstract: Optical sensors, systems, and methods are described, which may be used to provide or analyze information about a subject. The optical sensor may be placed in proximity to the subject and may include optical sources and optical detectors. The optical sources may irradiate the subject with optical signals and the optical detectors can detect signals from the subject. Analysis of the detected signals can yield information about the subject.
