Abstract: A system can include a non-light-emitting, variable transmission device a controller coupled and configured to provide power to the first non-light-emitting, variable transmission device; and a router configured to provide power and control signals to the first controller. In an aspect, the controller includes a first connector; the router includes a second connector; and a cable including a third connector and a fourth connector at different ends of the cable. The first and third connectors are coupled to each other, and the second and fourth connectors are coupled to each other. In another aspect, the system can include other non-light-emitting, variable transmission devices, and controllers. The system can be configured to perform a method of controlling the system that includes determining power requirements for the controllers and allocating power to the controllers corresponding to the power requirements.

Abstract: A wire used in the medical field for guiding purposes, as well as in other fields, such as in the field of orthodontics for teeth aligning purposes. The wire, when prepared for use in such applications, exhibits an innovative blend of advantageous properties, including enhanced kink resistance over stainless steel wires and enhanced stiffness over Nitinol wires, which enhance its use as a medical guidewire or stylet, and further, as an arch wire in orthodontia applications.

Abstract: The guidewire provides a core and wire coil construction. The core can be shaped with a generally squared-off distally facing shoulder that forms a platform for a proximal end portion of the wire coil. The wire coil can have a plurality of spaced apart coil turns at its proximal end portion. A bonding agent comprising an adhesive can be used to secure the core to the wire coil proximal end portion.

Abstract: An introducer system has a splittable sheath which includes a marker band. The marker band allows the sheath to be viewed under fluoroscopy while inserted within a patient, and while still allowing a medical device to be introduced therethrough. In addition, the marker band allows for the sheath to be split using a slitter in a longitudinal direction which permits the sheath to be removed from the venous system without having to be withdrawn over an end of the medical device. The marker band has perforations, comprises a mesh structure, or can comprise a braid structure, which each allow for the sheath, and the marker band, to be slittable.

Abstract: The slitter includes a handle section having a handle member and an arcuate section joined thereto, a knife blade, a clamp member and interfitting parts for mounting the clamp member to the handle members for limited vertical movement between catheter clamping and release positions, each of the arcuate section and the clamp member having vertically opposite facing surfaces for clampingly engaging opposite surface portions of any one of a number of different outer diameter catheters. The arcuate section has a nose portion for entering between the clamped catheter and the introducer when the introducer is to be removed from the catheter without being moved over the proximal terminal end of the catheter. The knife blade is located radially outwardly of the arcuate section surface that abuts against the clamped catheter, extends radially outwardly of the nose and is located rearwardly of the forwardmost part of the nose.

Abstract: A dilator is axially movable to have its tubular member movably extended through the tubular portion of an introducer with the dilator hub abuttable against the tubular portion proximal edge. A locking finger mounted to the introducer tab (or handle) is radially extendable into a hub recess to lockingly retain the dilator and introducer in a coupled relationship to prevent accidental axial separation. The recess is formed by the hub main body and a radially extending flange to open radially outwardly. In one embodiment, the introducer tab is of a flexibility for being manually bent to move the locking finger out of the recess to permit axial separation while in a second embodiment, a flange notch is provided for the locking finger to relatively move axially therethrough when the dilator and introducer are relatively rotated from a position where the locking finger abuts against the flange.
