Abstract
Abstract A method for performing a surgical operation on a body conduit includes the step of inserting into the conduit an apparatus having at its distal end an element the location of which is detectable from regions exterior of the body. The apparatus is moved within the conduit until the element is positioned relative to a predetermined location where the element functions as a target. Detecting the location of this target within the conduit facilitates insertion of a surgical instrument percutaneously of the body and toward the predetermined location. The targeting apparatus may be used with an endoscope and may include a variety of active and passive elements which form the target. The surgical instrument can be inserted percutaneously transverse to the axis of the conduit to perform a variety of surgical operations. Sidebranch occlusion in an insitu procedure is greatly facilitated by this method and apparatus.

Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
166 words
A method for performing a surgical operation on a conduit within a human body, comprising the steps of: inserting into the body conduit an elongate apparatus having a first axis extending between a distal end and a proximal end, the apparatus having at its distal end an element adapted to provide an indication of the location of the distal end of the device within the conduit; moving the apparatus axially through the conduit until the element is positioned relative to a predetermined location along the conduit; activating the element to produce a target positioned relative to the predetermined location along the conduit; detecting the activated element from a location exterior of the body to ascertain the predetermined location along the conduit; inserting percutaneously into the body a surgical instrument having a second axis extending to a distal tip; guiding the instrument along the second axis and toward the target; and operating the surgical instrument to perform the surgical operation on the conduit at the predetermined location.
Claim 2
Independent Claim
166 words
A method for performing a surgical operation on a conduit within a human body, comprising the steps of: inserting into the body conduit an elongate apparatus having a first axis extending between a distal end and a proximal end, the apparatus having at its distal end an element adapted to provide an indication of the location of the distal end of the device within the conduit; moving the apparatus axially through the conduit until the element is positioned relative to a predetermined location along the conduit; activating the element to produce a target positioned relative to the predetermined location along the conduit; detecting the activated element from a location exterior of the body to ascertain the predetermined location along the conduit; inserting percutaneously into the body a surgical instrument having a second axis extending to a distal tip; guiding the instrument along the second axis and toward the target; and operating the surgical instrument to perform the surgical operation on the conduit at the predetermined location.

14 words
The method recited in claim 9 wherein the occluding device is a ligating device.
Claim 12
Independent Claim
127 words
A method for performing a surgical procedure on one of a series of body conduits including a primary conduit and a secondary conduit extending laterally from the primary conduit, comprising the steps of: inserting into the primary conduit an apparatus having a first energy source and portions defining a lumen; issuing from the lumen a second energy source; guiding the second energy source laterally into the secondary conduit to form a target positioned relative to a predetermined location along the secondary conduit; inserting percutaneously into the body a surgical instrument adapted to perform the surgical procedure; guiding the surgical instrument toward the target from regions exterior of the body; and operating the surgical instrument to perform the surgical operation on the secondary conduit at the predetermined location.
Claim 13
Independent Claim
