The present invention is directed to an articulate minimally invasive surgical instrument with a flexible wrist to facilitate the safe placement and provide visual verification of the ablation catheter or other devices in Cardiac Tissue Ablation (CTA) treatments. In one embodiment, the instrument is an endoscope which has an elongate shaft, a flexible wrist at the working end of the shaft, and a vision scope lens at the tip of the flexible wrist. The flexible wrist has at least one degree of freedom to provide the desired articulation. It is actuated and controlled by a drive mechanism located in the housing at the distal end of the shaft. The articulation of the endoscope allows images of hard-to-see places to be taken for use in assisting the placement of the ablation catheter on the desired cardiac tissue. The endoscope may further include couplings to releasably attach an ablation device / catheter or a catheter guide to the endoscope thereby further utilizing the endoscope articulation to facilitate placement of the ablation catheter on hard-to-reach cardiac tissues. In another embodiment, the articulate instrument is a grasper or any other instrument with a flexible wrist and a built-in lumen to allow an endoscope to insert and be guided to the distal end of the instrument.

A nasal cannula assembly designed for contact with the nasalabidial area of a patient's face comprising a nasal cannula, a pair of oxygen supply tubes connected to opposite ends of the nasal cannula and a main oxygen supply line. The nasal cannula is made of a flexible plastic material molded into a light-weight hollow tubular member having a main body portion formed at an acute angle in the center and having a pair of spaced exterior orifices projecting from the body at an angle and curved upwardly and inwardly for directing gas flow into a patient's nostrils. Attachment points for oxygen supply tubes are above center of gravity of the nasal cannula to make it self-righting thus eliminating need for stiff supply tubing to orient cannula. Oxygen supply tubes made from ultra-high molecular weight PVC possess superior flexibility and low compression set so that little tension on the tubing is required to hold cannula in proper position. A main oxygen supply line made from ultra-high molecular weight PVC resists the formation of twisted loops that tend to block oxygen flow.

Disclosed is an ammunition cartridge case that includes a sleeve, a base fixedly attached to the sleeve and a fiber reinforced polymer composite annulus that is at least partially within the base. In certain embodiments, the sleeve and the base are formed partly or entirely from a metal, for example steel or stainless steel. The base has a central aperture that affords for the annulus ring to fit within. The annulus is dimensioned such that it fits securely within the central aperture of the base and has a center aperture wherein a primer can be located. The annulus ring contains a volume of composite fibers ranging from 10 to 90 volume percent. The annulus isolates the primer from the cartridge case and thereby prevents galvanic corrosion between the primer and case. In addition, a metallic foil can be present between the annulus and the cartridge case in order to assure proper securement of the annulus therewithin.
