An apparatus for targeting a desired target site on a body tissue comprising a wall of a first body cavity of a patient includes a target catheter. The framing member, when deployed into an expanded condition, has a framing member body which includes a three-dimensionally bulbous portion defining a maximum body footprint in a lateral dimension and has longitudinally spaced proximal and distal body ends which are both longitudinally spaced from the maximum body footprint. The proximal body end is attached to the target catheter. A protrusion has a diameter which is smaller than the maximum body footprint diameter. At least one target point is carried by the framing member and is adapted for placement adjacent the desired target site. At least one target pathway is attached to at least one target point. At least a portion of the target pathway is substantially spaced apart from the framing member body.
