GUIDE WIRE STRUCTURE FOR INSERTION INTO AN INTERNAL SPACE |
摘要 |
<p>A method is described of inserting guide wires into a lumen, for example into the human gastrointestinal tract. A guide wire structure is employed which comprises at least two guide wires (1, 2) each having a leading end portion which terminates in a leading end, the guide wires being connected to one another by a junction (3) at or adjacent their leading ends, the guide wires have a first position in which the leading end portions are substantially parallel to one another, a second position in which theleading end portions are curved, and a third position in which at least one of the leading end portions forms a loop. The guide wire structure is steered through the gastrointestinal tract by selectively advancing or retracting a single guide wire or advancing more than one guide wire simultaneously, according to the path which is required to be followed.</p> |
