Abstract
Abstract A multichannel probe comprising a hollow tube defining a distal end and a proximal end, the tube being made of a flexible self-supporting material enabling the tube to fold or to be curved, and said hollow tube being subdivided into at least three independent longitudinal channels by at least two internal partitions disposed longitudinally substantially parallel to the axis of symmetry of the tube.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
207 words
A method of endoscopically treating inorganic deposits in ducts utilizing a self-supporting elongated hollow flexible tube having a proximal end and a distal end and a longitudinal axis, the tube divided into at least three channels extending along the longitudinal axis of the tube, comprising; inserting the distal end of the tube into a lumen of the duct and advancing the tube to the inorganic deposit; inserting a laser optical fiber for transmitting laser radiation into one of the channels of the tube and advancing the laser optical fiber to the inorganic deposit; inserting an observation optical fiber for transmitting light radiation into one of the channels of the tube and advancing the observation optical fiber to the region of the distal end of the tube; selectively injecting an irrigation medium into one of the channels of the tube; destroying the inorganic deposit by applying laser radiation to the laser optical fiber while visually monitoring the treatment through the observation optical fiber; withdrawing the laser optical fiber and the observation optical fiber at the conclusion of treatment; stopping injection of the irrigation medium; maintaining the tube in the body lumen of the duct for draining the treated lithiases prior to withdrawing the tube; and withdrawing the tube.
Claim 2
Independent Claim
207 words
A method of endoscopically treating inorganic deposits in ducts utilizing a self-supporting elongated hollow flexible tube having a proximal end and a distal end and a longitudinal axis, the tube divided into at least three channels extending along the longitudinal axis of the tube, comprising; inserting the distal end of the tube into a lumen of the duct and advancing the tube to the inorganic deposit; inserting a laser optical fiber for transmitting laser radiation into one of the channels of the tube and advancing the laser optical fiber to the inorganic deposit; inserting an observation optical fiber for transmitting light radiation into one of the channels of the tube and advancing the observation optical fiber to the region of the distal end of the tube; selectively injecting an irrigation medium into one of the channels of the tube; destroying the inorganic deposit by applying laser radiation to the laser optical fiber while visually monitoring the treatment through the observation optical fiber; withdrawing the laser optical fiber and the observation optical fiber at the conclusion of treatment; stopping injection of the irrigation medium; maintaining the tube in the body lumen of the duct for draining the treated lithiases prior to withdrawing the tube; and withdrawing the tube.
Claim 3
Independent Claim
198 words
A method of endoscopically treating lithiases utilizing a multichannel probe of a self-supporting elongated hollow flexible tube having a proximal end and a distal end and a longitudinal axis, the tube divided into at least three channels extending along the longitudinal axis of the tube, comprising: inserting the distal end of the tube into a lumen of the body to the lithiases; inserting a laser optical fiber for transmitting laser radiation into one of the channels of the tube and advancing the laser optical fiber to the lithiases; inserting an observation optical fiber for transmitting light radiation into one of the channels of the tube and advancing the observation optical fiber to the region of the distal end of the tube; selectively injecting an irrigation medium into one of the channels of the tube; destroying the lithiases by applying laser radiation to the laser optical fiber while visually monitoring the treatment through the observation optical fiber; withdrawing the laser optical fiber and the observation optical fiber at the conclusion of treatment; stopping injection of the irrigation medium; maintaining the tube in the body lumen for draining the treated lithiases prior to withdrawing the tube; and withdrawing the tube.

Claim 5
Dependent Claim
55 words
The method of claim 2, wherein the tube includes four channels and the method includes first inserting a guide wire into the lumen; inserting the tube onto the guide wire for advancing the tube along the guide wire to the region of the lithiases; and withdrawing the guide wire at the end of the treatment.
Claim 6
Dependent Claim
33 words
The method of claim 2, including the step of anesthetizing the lumen by injecting an anesthetic into one channel of the tube as the tube is being introduced and advanced along the lumen.
Claim 7
Dependent Claim
24 words
The method of claim 2, including injecting a contrast substance into the tube to verify the position for drainage after treatment of the lithiases.
Claim 8
Independent Claim
198 words
A method of endoscopically and percutaneously treating lithiases utilizing a self-supporting elongated hollow flexible tube having a proximal end and a distal end and a longitudinal axis, the tube divided into at least three channels extending along the longitudinal axis of the tube, comprising: inserting the distal end of the tube percutaneously into the body and advancing the tube to the lithiases; inserting a laser optical fiber for transmitting laser radiation into one of the channels of the tube and advancing the laser optical fiber to the lithiases; inserting an observation optical fiber for transmitting light radiation into one of the channels of the tube and advancing the observation optical fiber to the region of the distal end of the tube; selectively injecting an irrigation medium into one of the channels of the tube; destroying the lithiases by applying laser radiation to the laser optical fiber while visually monitoring the treatment through the observation optical fiber; withdrawing the laser optical fiber and the observation optical fiber at the conclusion of treatment; stopping injection of the irrigation medium; maintaining the tube in the body lumen for draining the treated lithiases prior to withdrawing the tube; and withdrawing the tube.
