Abstract: A system for vaporization of plant-derived concentrates is provided that includes a reusable device that contains electronic features, one or more heaters; and a disposable cartridge that provides an array of concentrate aliquots. Each concentrate aliquot of the array can conveniently be individually addressed by one of the heaters.

Abstract: Interventional catheter assemblies and components providing improved operational control of interventional catheters and/or operating heads of interventional catheters are provided. In general, controllers incorporate at least two operator selectable control features for controlling operation of the interventional catheter and/or an operating head, and are housed independently of the interventional catheter operating systems and other control systems, which may be provided in a housing located or locatable at a proximal region of the interventional catheter. The controller may be both dockable in and removable from the housing, and is operable in both a docked condition and a removed condition, providing flexibility and mobility in operational control during an interventional procedure.

Abstract: Interventional catheter assemblies that operate over a guide wire are disclosed. Specifically, an elongated flexible catheter is associated at its proximal end with a housing having a guide wire port where the guide wire exits the housing. The housing additionally incorporates a guide wire brake mounted within a slot positioned a distance from the guide wire port for engaging and releasing a guide wire. The slot is generally arranged at an angle to the path of the guide wire as it exits the guide wire port. When the guide wire is clamped in the angled slot, variable lengths of exposed guide wire accumulate in a substantially unrestrained condition when the flexible catheter is advanced and retracted relative to the guide wire, allowing movement of the distal end of the catheter over considerable distances without repositioning and re-clamping the proximal end of the guide wire.
