Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
A method of pin-pointing and cutting a target with a fluid jet, comprising the steps of: providing a fluid jet system including a variable pressure pump, a source of fluid in communication with the pump, a delivery tube in communication with an outlet of the pump and an instrument in communication with the delivery tube having an orifice for creating a fluid jet as the pumped fluid exits therefrom; pumping fluid at a low pressure through the instrument to create a low pressure jet; directing the low pressure jet onto a target to pinpoint the target to be cut; pumping the fluid at a higher pressure while maintaining the jet on the target; wherein cutting of the target is achieved at the higher pressure, while the jet at the lower pressure is unable to cut the target.
Claim 2
Independent Claim
137 words
A method of pin-pointing and cutting a target with a fluid jet, comprising the steps of: providing a fluid jet system including a variable pressure pump, a source of fluid in communication with the pump, a delivery tube in communication with an outlet of the pump and an instrument in communication with the delivery tube having an orifice for creating a fluid jet as the pumped fluid exits therefrom; pumping fluid at a low pressure through the instrument to create a low pressure jet; directing the low pressure jet onto a target to pinpoint the target to be cut; pumping the fluid at a higher pressure while maintaining the jet on the target; wherein cutting of the target is achieved at the higher pressure, while the jet at the lower pressure is unable to cut the target.
Claim 3
Dependent Claim
24 words
The method as recited in claim 1 further comprising the step of utilizing the jet to break up the cut target into smaller fragments.
Claim 4
Dependent Claim
17 words
The method as recited in claim 1 wherein the low pressure includes pressures less than 1,000 p.s.i.
Claim 5
Dependent Claim
17 words
The method as recited in claim 1 wherein the higher pressures includes pressures greater than 1,000 p.s.i.
Claim 6
Dependent Claim
30 words
The method as recited in claim 1 further comprising the step of dispersing a visually observable dye in the fluid before the low pressure jet is directed onto the target.
Claim 7
Dependent Claim
16 words
The method as recited in claim 1 wherein the target is supported by the human body.
Claim 8
Dependent Claim
12 words
The method as recited in claim 6 wherein the target is tissue.
Claim 9
Dependent Claim
12 words
The method as recited in claim 6 wherein the target is bone.
