Abstract: A tip assembly for a liquefaction surgical handpiece. The tip assembly has an inner connector and an outer cap. The outer cap contains an external thread for attaching the tip assembly to a handpiece. The inner housing contains an alignment tab and fits within the outer cap so as to allow rotation of the inner connector within the outer cap. The inner and outer liquefaction tip tubes are frictionally fit into a bore in the inner connector. The proximal end of the inner housing contains a gasket that seal the inner housing against the handpiece.

Abstract: A tip assembly for a liquefaction surgical handpiece having a break-away or frangible tip protector. The tip protector protects the delicate tip from damage during handling and shipment, but is easily removed prior to use.

Abstract: A tip for a surgical handpiece having two coaxial tubes or channels mounted within a body. The tip has one or more features that shape the fluid discharge so as to optimize the performance of the handpiece for varying parts of the surgical procedure.

Abstract: A surgical handpiece having a tip with at least two coaxially spaced electrically conductive tubes. The tubes are separated by an electrical insulator. The interior of the inner tube is used for aspiration of liquefied tissue. The outer tube is surrounded by a soft irrigation sleeve that forms an irrigation fluid path. The distal portion of the interior tube terminates inside of the outer tube so as to form a boiling region. Surgical fluid from the irrigation fluid path can enter the boiling region through a hole or port in the outer tube. Electrical current is passed between the inner and outer tube to rapidly boil any surgical fluid in the boiling region. The boiling fluid rapidly expands out of the ring between the tube ends and forces hot fluid to contact the targeted tissue, thereby liquefying the tissue and allowing the tissue to be aspirated. Such a construction allows the boiling chamber to be self-priming and operate even if the outer tube is occluded with material.

Abstract: A container for delivery of a surgical fluid to a surgical handpiece is disclosed. The container includes a volume for receiving the surgical fluid to be delivered to the handpiece and an end for removably engaging a receptacle in a surgical console and for fluidly coupling with a source of pressurized fluid in a surgical console.

Abstract: An apparatus for delivery of a surgical fluid to a surgical handpiece is disclosed. The apparatus generally includes a container and an adapter receiving one end of the container. The container holds the surgical fluid to be delivered to the handpiece. The adapter is for removably engaging a receptacle in a surgical console and for fluidly coupling with a source of pressurized fluid in a surgical console.
