Abstract: A novel lipid concentrate vaporizer apparatus comprises an elongate hollow tubular upper portion including an opening at one end, a lower portion including a bulbous closed second end, a solid stem extending away from the bulbous portion and a solid heating tip formed at the end of the stem. The upper and lower portions share a wall thickness and the bulbous end includes one or more air intake holes formed at a position above the stem and when the tip is heated to a temperature to vaporize and not combust the lipid concentrate contained in a vessel having a specific shape, the tip makes contact with the lipid concentrate and the resulting vapor is drawn into the upper portion via the holes by a user creating suction and inhaling at the opening at the one end.

Abstract: The present invention provides devices, instruments, systems, and methods to navigate medical instruments within the thoracic cavity. More specifically, the present invention provides a navigation system comprising medical instruments having electromagnetic tracking functionality and the integration of previously acquired imaging into a user interface of the navigation system.

Abstract: The present invention is a surgical instrument for use with a viewing system and, if desired, an irrigation fluid supply system. The surgical instrument can be readily assembled and includes an elongated shaft and a flexible endoscope or optical assembly that can be readily and removably secured along substantially the entire length of the shaft by a mounting tube or other mounting means.

Abstract: A surgical instrument for improved viewing of a surgical site by a surgeon from the perspective of a working element of the instrument. The surgical instrument includes an elongated shaft with a distal operating portion extending at least about one-fourth of the length of the shaft. A working element is disposed on a distal end of the shaft. An elongated fiberoptic assembly is included, having image fibers with a distal end with an objective lens for defining a predetermined field-of-view, and a coupling device at a proximal end for coupling same to a viewing system. A mounting device is utilized for mounting the fiberoptic assembly to the shaft along the length of the distal operating portion thereof. The distal end of the image fibers is positioned with a predetermined portion of the working element within the field-of-view of the fiberoptic assembly.
