Abstract: An apparatus for removing suspect breast tissue which includes a penetrating member in the form of a stylet with a tapered front end that can be guided along a localization guide wire. The apparatus also including a first cutting device in the form of a cannula slidingly engaged with the stylet. A driving assembly is in driving engagement with the cannula and, upon activation, potential energy stored in the driving assembly acts to drive the forward end of the cannula forward of the stylet's forward end so as to define a core cavity. A second cutting device which includes a garret wire having a looped section positioned within a recess at the forward end of the cannula is also provided. The driving assembly preferably also acts to rotate the cannula with a cam arrangement such that the cannula rotates when being driven forward.

Abstract: A light filtering system for creating perception of a stereoscopic image from a conventional video image is disclosed. The light filtering system has a first lens formed of a red filter and a second lens formed of a green filter. In a preferred embodiment, the red filter will filter light to the dominant eye while the green filter will filter light to the non-dominant eye. A method creating perception of a stereoscopic image by a viewer of a conventional video image also is disclosed.

Abstract: A method for percutaneous excisional breast biopsy and a percutaneous excisional breast biopsy device (PEBB device).

Abstract: A method of using a protective apparatus with an intravenous system and especially an implanted intravenous needle assembly or a Y-junction of a piggy back intravenous system. The protective apparatus includes a protective sheath having an open end and a second end suitable for connection with a fluid introduction source. The sheath includes a slot along its lowest surface and can include a needle extending within a hollow interior defined by the sheath. The sheath features two curved runner sections or a pair of wing-shaped runners which extend from a channel section defining a portion of the slot. The curved runner sections and wing-shaped runners allow for easy insertion of a needle into a taped receptive port of an implanted intravenous needle assembly. An alternate embodiment features two slits with or without an additional channel/elongated aperture combination.

Abstract: A syringe assembly which greatly reduces the chances of an operator coming in contact with an infectious needle. The syringe assembly includes an outer casing within which an inner chamber slides. A plunger having a sealing plug at one end extends into both the inner chamber and outer casing such that the sealing plug is fixedly secured within the interior of the inner chamber and outer casing, yet free to slide along the length of the inner chamber. The inner chamber and outer casing are structured such that the needle can be retracted completely within the interior of the outer casing when the inner chamber is releasably locked at the rear end of the outer casing. The needle can also be placed into an operational position when the inner chamber with attached needle is releasably locked at the forefront of the outer casing.

Abstract: An aortic graft that is specifically constructed for intraluminal insertion and comprising a flexible hollow, tubular material, having a generally cylindrical shape with an upper end and lower end and having a minor and major axis, and having disposed along its major axis a plurality of parallel struts, the struts having angled hooks with barbs at their upper ends, the upper ends of the struts extending beyond the upper end of the tubular material, thus allowing the graft to be securely attached to the inside of the aorta above the aneurysm. A tubular device for inserting the graft is also disclosed.
