Abstract
Apparatus and methods for percutaneously forming a passageway between adjacent vessels, a vessel and an organ, or different regions of an organ are provided comprising first and second catheters carrying distally positioned electromagnets. The first and second catheters are percutaneously advanced to positions within a body so that the distal endfaces oppose one another and magnetically attract one another, causing the lumens of the catheters to become aligned. A cutting wire is then advanced out of the first lumen, through the thickness of the tissue captured between the catheters, and into the second lumen. The cutting wire may be advanced fully through the second catheter so that it exits the patient, and upon removal of the first and second catheters, serves as a guide wire. Methods of percutaneously performing surgery are also provided.
