US Patent:

20010002562, Jun 7, 2001

Filed:

Jan 19, 2001

Appl. No.:

09/766361

Inventors:

Timothy Moutafis - Gloucester MA, US
C. Coffin - Topsfield MA, US
Frank Patterson - Exeter NH, US
Marvel Yoder - Andover MA, US

International Classification:

B26D001/00
B26D007/00
B26F003/00

US Classification:

083/013000, 083/177000

Abstract:

A system for generating a high pressure fluid jet includes a variable pressure pump and a burst resistant delivery tube which safely conducts the pressurized stream to an instrument. The pump may include a disposable diaphragm pump cartridge which is driven by a reusable pump. The delivery tube may be a coiled hypo tube which enhances flexibility.

Appl. No.:

8/481566

Inventors:

Frank Van Patterson - Exeter NH
Marvel John Yoder - Andover MA
Timothy E. Moutafis - Gloucester MA

Assignee:

HydroCision, Inc. - Wilmington MA

International Classification:

A61B 1720

US Classification:

604 22

Abstract:

An instrument for delivering a variable pressure stream of fluid as a coherent jet. The instrument may be configured for holding in the hand of a user or for manipulation by machine control. The orifices may be oriented axially, transversely or obliquely. A deflector may be provided opposite the orifice to transform the jet stream into a harmless spray. The deflector may be slidable (in the axial mode) or pivotable (in the transverse mode) to ensure a small instrument profile. The instrument may be moldable allowing the user to reshape the jet tip into a desired configuration. The instrument may be remotely steerable and enable a user to selectively alter the direction of the jet without having to remove the instrument from the surgical site.

International Classification:

H01S 308
H01S 322

US Classification:

331 945G

Abstract:

A high pressure, high power, continuous wave electro-dynamic laser having one of the electrodes (preferably the cathode) made of a porous conductive surface and a backing material capable of broad band acoustic absorption. Such an arrangement effectively absorbs acoustic disturbances which arises primarily from a linear instability within the resonant cavity of the electro-dynamic laser and thereby substantially reduces output flux modulations within the resonant cavity.

Assignee:

Hydrocision, Inc. - Wilmington MA

International Classification:

B61B 1720

US Classification:

604 22

Abstract:

A method of pin-pointing a fluid jet onto a target involves pumping fluid at a low pressure through a jet creating instrument, directing the low pressure jet onto a target and pumping the fluid at a higher pressure while maintaining the jet on the target.
