Abstract: A coaxial illuminated laser endoscopic probe and active numerical aperture control apparatus and method of use, succinctly known as an illumination and laser source, capable of selectively providing illumination light and laser treatment light through a single optical fiber. The apparatus and method is especially useful during ophthalmic surgery. The present art is capable of providing the aforesaid through an optical fiber of such small size that heretofore said fiber was only useable for laser treatment light only. The present art also, with its unique optical system, allows for two illumination light outputs from a single illumination source. The apparatus utilizes a phototoxicity risk card to calibrate the system to prior art or safe illumination levels since the unique optical system provides illumination light of greater intensity than the prior art.

Abstract: A microsurgical laser probe is provided with a distal end portion of an optic fiber that projects from a tubular sleeve of the probe and can be caused to bend relative to the probe sleeve by manual manipulation of a mechanism on a handle of the probe.

Abstract: A device for radial optic neurotomy comprising a radial optic neurotomy knife and its method of use. Comprising in a preferred embodiment, a uniquely formed asymmetrical “V” shaped tip having a first sharpened leg and a second dulled leg and a depth gauge. In a preferred embodiment said depth gauge comprises a laser mark which is substantially perpendicular with a central axis of a tip holding shaft. The device is specially designed for performing the radial optic neurotomy (RON) surgical procedure and thereby promoting relaxation of the scleral outlet.

Abstract: A high efficiency ultrasonic surgical aspiration tip apparatus and accompanying method for surgical use. The apparatus has one or more substantially “V” or “U” shaped cuts in a contacting. The apparatus and method of use provides a cutting action at the contacting end when the tip is ultrasonically excited. The apparatus and method of use further provides a substantially uniform ultrasonic and aspiration field due to the positioning and shape of the substantially “V” or “U” shaped cuts. The aforesaid further allows a surgeon to position the ultrasonic generator handpiece at any rotational angle for provision of the benefits cited.

Abstract: An ophthalmic surgery light transmitting apparatus has an optic fiber having a flexible length with a light source connector mounted on one end of the optic fiber and the opposite end of the optic fiber being adapted to be mounted to an ophthalmic surgery instrument to provide illumination for the instrument. The cross-sectional area of the optic fiber transitions as it extends from the end connected to the light source connector to the opposite end of the optic fiber. The optic fiber transitions from a larger cross-sectional area of the optic fiber at the light source connector to a smaller cross-sectional area of the optic fiber at the opposite end.

Abstract: An assembly used to adapt a BNC type connector of a microsurgical optic fiber instrument to a threaded SMA type bushing of a light source includes an adapter that can be threaded on the bushing of the light source and is also connectable to the BNC connector.

Abstract: A microsurgical instrument used in ophthalmic surgery to remove proliferative membranes during a surgical procedure treating proliferative vitreoretinal membrane disorders and other macular diseases where the microsurgical instrument has a instrument handle, a tip, and abrasive particles attached to a scraping edge projecting beyond the tip. The microsurgical instrument may be fitted with infusion, aspiration, or illumination sources, and these sources are directed to the surgical site in proximity to the scraping edge, the abrasive particles on the edge scrape membranes to remove tissue at the surgical site. In one embodiment, the microsurgical instrument may be configured with a retractable/extendable pick where the relative stiffness of the pick and the edge may be adjusted. In another embodiment the edge may also be angularly positionable as it is retracted/extended from the microsurgical instrument.

Abstract: An energy efficient air distribution system placed within the conditioned space of a building comprising a duct having an interior volume for conducting air. One of the exterior surfaces may have an ornamental design providing the impression the device is actually cornice molding. At least one recess is positioned along the exterior surface of the duct, such that it is obscured from view by a viewer standing within an occupancy zone of a room. An outlet is positioned within the recess for directing a flow of air from the duct interior volume through the exterior surface. The duct serves a function of conducting air throughout the room, and also has an aesthetically pleasing appearance. Junction boxes may be placed within the conditioned space for connecting the ducts. Junction boxes may further include an ornamental exterior for a pleasing aesthetic appearance.

Abstract: A heat retentive server, comprising a central portion comprising a heat storage member formed of a material which is preferably susceptible to being heated by induction, is provided with one or more valves which are normally in closed positions, and are capable of opening to vent excess pressure in the central portion. In one preferred embodiment, a valve is placed so as to allow communication between the central portion and a different interior region of the server. In another embodiment, a valve is placed so as to allow communication between the central portion and the exterior of the server. In another embodiment, a server is provided with at least one valve of each type.

Abstract: A surgical instrument comprises an instrument head and an instrument handle. The instrument head has a proximal end, a distal end, a head static part at the proximal end, a reciprocative part generally at the proximal end, and a moveable distal part at the distal end. The reciprocative part is operatively connected to the moveable distal part so that movement of the reciprocative part between forward and rearward positions causes movement of the moveable distal part between first and second positions. The instrument handle has a handle body attachable to the head static part of the instrument head, a handle plunger configured for reciprocating relative to the handle body generally along the instrument axis, and a lever arm. The handle plunger is operatively engageable with the reciprocative part of the instrument head when the head static part is attached to the handle body.
