1. A method of treatment a human or veterinary patient involving two adjacent bodily structures comprising:

  • providing a first catheter having a first interior channel, the first catheter having a first orifice between said first interior channel and an exterior of the catheter, said first catheter having a first magnetically attracting tip, said first magnetically attracting tip comprising a ferromagnetic material located in a length of said first catheter that includes said first orifice, said first magnetically attracting tip having a polarity parallel to said first interior channel;

    providing a second catheter having a second interior channel, the second catheter having a second orifice between said second interior channel and an exterior of the second catheter through a side wall of said second catheter, said second catheter having a second magnetically attracting tip, said second magnetically attracting tip comprising a ferromagnetic material, located in a length of said second catheter that includes said second orifice, said second magnetically attracting tip comprised of three magnetic sections, a first magnetic section, a middle magnetic section and a third magnetic section, said first and third magnetic sections having opposing polarity, and said middle magnetic section having its polarity oriented perpendicular to the polarity of said first and second section, said second orifice located in said middle magnetic section, wherein the second catheter includes a radio-opaque marker disposed along a distal portion thereof to indicate a rotational orientation of the second orifice;

    locating said first catheter within a first body structure;

    locating said second catheter within a second body structure adjacent the first body structure;

    positioning the second catheter to rotationally align the second orifice of the second catheter with the first orifice of the first catheter by observing the radio-opaque marker on the second catheter under image guidance;

    placing said first magnetically attracting tip within said first body structure adjacent said second magnetically attracting tip with a layer of tissue between said first magnetically and second magnetically attracting tips such that said first and second magnetically attracting tips align and magnetically couple to each other with first and second orifices opposed to each other but separated by the layer of tissue between them; and

    passing a piercing device through the first orifice, through the layer of tissue, and into the second orifice.
