Abstract: An introducer assembly introduces an elongate member into a tubular structure and may be configured into ready, introduced, and detached modes. The introducer assembly has a guide tube, a slide collar, and proximal and distal connector assemblies. The guide tube has a proximal body, and a distal portion, the distal portion being rotatably connected to the proximal body. The slide collar has a grip, a slide post, and a centered capture structure. The proximal connector assembly is detachably nested within the centered capture structure. The distal connector assembly is detachably nested within the distal portion and is connectable to the tubular structure. The introducer assembly may be converted from the ready mode to the introduced mode to the detached mode by manual manipulation to introduce and secure the elongate member within the connected tubular structure, and then detach the guide tube leaving the elongate member within the connected tubular structure.

Abstract: An electromagnetic radiation (EMR) delivery system for delivering EMR at wavelengths, intensities, exposures, and durations to locations inside and/or outside a patient's body in, on, and surrounding a tubular structure such as a tube, catheter, and/or a catheter extension to prevent, reduce, and/or eliminate infectious agents in, on, or surrounding the tubular structure. A smart light engine box generates the therapeutic EMR, controls treatments, and monitors the health of the system. A fiber optic disposable, introduced and positioned by an introducer assembly, makes at-home use of the EMR delivery system possible. Specific embodiments of the EMR delivery system for use with peritoneal dialysis catheters, dialysis accesses, and hemodialysis accesses are also disclosed.

Abstract: Load cells incorporating rocker pin configured columnar central structures within a weighing system have the attribute of self-erecting upon being displaced from a vertical orientation due to dynamic transverse loading effects, as may be occasioned by vehicle movements onto a scale. The resultant transient vector forces thus developed have been observed to cause a rotational phenomenon in the rocker pin configured cells which causes unacceptable damage to the instrumentation control communication components of the load cell system. A mounting technique for such load cells is developed wherein only these rotation inducing forces are restrained, while the vertical force vectors representing valid load data are maintained in an unrestricted or uncompromised manner. In one aspect of the invention, a hexagonal form of mounting between a rocker pin neck-contact surface region and a corresponding receiver cavity achieves a fully pivoting and freely abutting geometry while effecting the noted restriction of rotation.
