Method and apparatus for endoconduit targeting
First Claim
1. 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.

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.

11. 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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A surgical apparatus for illuminating a series of body conduits including a primary conduit and a secondary conduit extending laterally from the primary conduit, the apparatus comprising:
-
an elongate tube adapted for insertion into the primary body conduit and having a proximal end, a distal end, and portions of the tube defining a lumen; a first energy source providing energy emanating from the distal end of the tube and having first energy characteristics; a second energy source movable along the tureen of the tube to regions exterior of the tube, the second energy source providing energy with second energy characteristics different than the first energy characteristics of the first energy source; and the second energy source being adapted for movement laterally of the tube and into the secondary conduit. - View Dependent Claims (21, 22, 23, 24, 25, 26)
