Abstract:
An embodiment of the targeting system includes a penetrating beam emitter (10), a penetrating beam receiver (13), and a targeting assembly (16). The targeting assembly is adjustable. The targeting assembly (16) has a targeting marker in a path of a penetrating beam (19) provided by the emitter (10). The targeting marker is at least partially opaque to a penetrating beam (19) emitted by the emitter (10), and the targeting marker indicates a targeting point on a target axis. The targeting assembly (16) further includes a targeting beam device capable of providing a targeting beam along the target axis. In addition, the present invention includes a method of calibrating a targeting system, and a method of targeting an area of interest.
Abstract:
A method and system for the application of molecular sieves to the removal of carbon dioxide and carbon monoxide from the patient expired gases during anesthesia. The system is especially useful in anesthesia using any of the halogenated ether inhalation anesthetic agents. The expired gases are dried using a non-reactive desiccant to remove water, passed through a filter capable of removing particles larger than 0.3 microns, passed through a bed containing either natural or synthetic molecular sieves capable of removing carbon dioxide and carbon monoxide and then returned to the breathing circuit for recirculation to the patient.
Abstract:
Provided is a sevoflurane anesthetic product which can remain substantially undegraded after long periods of storage, as well as a method for preparing the product. The product comprises sevoflurane in a glass container having a water content of less than 130 ppm. The method comprises drying sevoflurane having a water content of greater than 130 ppm to a water content les than 130 ppm. A preferred method of drying comprises contacting a sevoflurane composition having a water content of greater than 130 ppm with alumina-containing molecular sieves such that the water content is reduced to less than 130 ppm.
Abstract:
A targeting system, which provides an adjustable optical assembly, for use with imaging systems having a penetrating beam source, a penetrating beam receiver. The optical assembly has a targeting marker in the path of a penetrating beam emitted by the source. The targeting marker is at least partially opaque to the penetrating beam emitted by the source, and the targeting marker indicates a targeting point on a target axis. The optical assembly further includes a sensible targeting beam device that is capable of providing a sensible targeting beam coaxial and collinear with the target axis. In addition, there is provide a method of aligning the targeting system, such as the system described above, and a method of targeting an area of interest. One advantage of the system and method is that it requires only a two point alignment.

Abstract:
This invention is an invasive instrument (400), such as a biopsy needle, syringe or drill, adapted to be guided by an energy beam (66) such as a laser beam along a predefined line of sight path (65) toward a subsurface target (50). The instrument is adapted for use in conjunction with an energy beam targeting and directing system which directs an energy beam in a line of sight path toward a target. The instrument includes a means for percutaneously accessing a subsurface target, an energy conducting portion and an energy responsive means interposed between the means for percutaneously accessing a subsurface target and the energy conducting portion; and a method whereby an operator monitors the energy responsive means for a visual indication of alignment of the instrument with the predefined line of sight path, while advancing the means for percutaneously accessing the subsurface target along the line of sight path toward the target.
