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 includes a disposable diaphragm pump cartridge which is driven by a reusable pump. The delivery tube may be a coiled hypo tube which enhances flexibility.

Fluid jet cutting system

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.

Instrument for creating a fluid jet

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.

Method for using a fluid jet cutting system

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.
