Patent number: 6860868Abstract: A surgical handpiece having at least two lumens or tubes mounted to a body. At least one tube is used for aspiration and at least one other tube is used to inject heated surgical fluid for liquefying a cataractous lens. A portion of the second tube is enlarged to form a pumping chamber. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the second tube. The pumping chamber may use a pair of electrodes.Type: GrantFiled: August 29, 2003Date of Patent: March 1, 2005Assignee: Alcon Manufacturing, Ltd.Inventors: Glenn Sussman, Donald M. Cohen

Publication number: 20050038417Abstract: 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.Type: ApplicationFiled: August 15, 2003Publication date: February 17, 2005Inventors: Ziad Ghannoum, Sean Madden, Glenn Sussman, John Underwood

Publication number: 20040053818Abstract: An improved solution for use in the removal of cataractous lenses via liquefracture is described. The liquefracture solution contains a viscosity-enhancing agent to increase the residence time of the solution in the heating chamber of the liquefracture handpiece, thereby increasing the expulsion force of the solution from the handpiece (i.e., “pulse force”). An agent that releases gas when the liquefracture solution is heated in the handpiece may also be included in the solution, thereby also enhancing the pulse force of the solution upon expulsion from the handpiece. The solution preferably also contains a partially water-soluble agent that forms a temporarily insoluble precipitate when heated in a liquefracture handpiece. The precipitate acts as an abrasive agent when expelled with the liquefracture solution from the handpiece, thereby facilitating the cutting and disintegration of the cataractous lens material.Type: ApplicationFiled: May 30, 2003Publication date: March 18, 2004Inventors: Mandar V. Shah, Glenn Sussman, Donald M. Cohen, Uday Doshi

Patent number: 6589204Abstract: A surgical handpiece having two coaxial tubes or channels mounted within a body. The first tube is used for aspiration and is smaller in diameter than the second tube so as to great an annular passage between the first and second tube. The annular passage communicates with a pumping chamber formed between two electrodes. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the annular passage. The electrodes are insulated from each other.Type: GrantFiled: June 27, 2000Date of Patent: July 8, 2003Assignee: Alcon Manufacturing, Ltd.Inventors: Glenn Sussman, Martin J. Padget, Donald M. Cohen

Patent number: 6589201Abstract: A surgical handpiece having two coaxial tubes or channels mounted within a body. The first tube is used for aspiration and is smaller in diameter than the second tube so as to create an annular passage between the first and second tube. The annular passage communicates with a pumping chamber formed between two electrodes. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the annular passage. The distal end of the annular gap is sealed by sealing together the distal ends of the first and second tube and a plurality or orifices or ports may be formed near the seal. As the expanding gas is propelled down the annular gap, the gas/liquid stream is forced out of the distal orifices in a controlled and directed manner. The distal end of the first and second tubes may contain a bend.Type: GrantFiled: March 14, 2000Date of Patent: July 8, 2003Assignee: Alcon Manufacturing, Ltd.Inventors: Glenn Sussman, Martin J.

Publication number: 20020161326Abstract: A tip for a liquefraction surgical handpiece. The tip uses at least two channels or tubes. One tube is used for aspiration and at least one other tube is used to inject heated surgical fluid for liquefying a cataractous lens. The distal portion of the injection tube terminates just inside of the aspiration tube and can be steered or directed so that heated fluid escaping the injection tube can be injected directly into the eye or reflected off of the internal wall of the aspiration tube prior to entering the eye. Alternatively, the injection tube may be relatively rigid but be extendable or contain a rotatable deflector that alternatively allows the heated fluid to be injected directly into the eye or reflected off of the internal wall of the aspiration tube. The handpiece may also contain other tubes, for example, for injecting relatively cool surgical fluid.Type: ApplicationFiled: October 28, 1999Publication date: October 31, 2002Inventors: GLENN SUSSMAN, THOMAS G. CAPETAN, DONALD M. COHEN

Patent number: 6398759Abstract: A surgical handpiece having two coaxially mounted tubes or channels mounted to a body. The first tube is used for aspiration and is smaller in diameter than the second tube so as to create an annular passage between the first and second tube. The annular gap communicates with a pumping chamber formed between two electrodes. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the annular gap. The distal end of the annular gap is sealed by frictionally fitting together the distal ends of the first and second tube. One or more grooves formed in either the first or second tubes allow fluid being propelled down the annular gap to escape. A stop may be provided against which the escaping fluid impinges such as by crimping the second tube near the distal end of the second tube.Type: GrantFiled: October 17, 2000Date of Patent: June 4, 2002Assignee: Alcon Manufacturing, Ltd.Inventors: Glenn Sussman, Donald M.

Patent number: 6315755Abstract: A control system for a Liquefracture handpiece that uses output from a surgical console to generate a control signal for an RF amplifier. The output from the RF amplifier is used to drive the handpiece heating element. To prevent excessive heated fluid from entering the eye, the vacuum in the handpiece is monitored and excessive or rapid increases in vacuum level (indicating an occlusion or low aspiration flow) causes the power to the heating element to be reduces or eliminated.Type: GrantFiled: December 14, 1999Date of Patent: November 13, 2001Assignee: Alcon Manufacturing, Ltd.Inventor: Glenn Sussman
