Apparatus and method for targeting a body tissue
First Claim
1. An apparatus for targeting a desired target site on a body tissue comprising a wall of a first body cavity of a patient, the apparatus comprising:
- a target catheter having a longitudinally extending target catheter lumen surrounded by a tubular target catheter wall having an outer surface;
a framing member having a collapsed condition in which the framing member is adapted for insertion into the first body cavity and an expanded condition in which the framing member is adapted for placement within the first body cavity, the framing member, when deployed into the expanded condition, having;
a framing member body which includes a three-dimensionally bulbous portion defining a maximum body footprint in a lateral dimension and having longitudinally spaced proximal and distal body ends which are both longitudinally spaced from the maximum body footprint, a diameter of the bulbous portion being significantly smaller at the proximal and distal body ends than at the maximum body footprint, the proximal body end being attached to the outer surface of the target catheter wall, anda protrusion located at the distal body end, the protrusion having a diameter which is smaller than the diameter of the maximum body footprint, the protrusion extending longitudinally distally from the distal body end of the bulbous portion;
at least one target point carried by the framing member and adapted for placement adjacent the desired target site; and
at least one target pathway attached to at least one target point, at least a portion of the target pathway extending through the target catheter lumen, and the target pathway being substantially spaced apart from the framing member body.

Abstract
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.

13. An apparatus for targeting a desired target site on a body tissue comprising a wall of a first body cavity of a patient, the apparatus comprising:
-
a target catheter having a longitudinally extending target catheter lumen surrounded by a tubular target catheter wall having an outer surface; a framing member defining a longitudinally oriented central framing member axis and having a collapsed condition in which the framing member is adapted for insertion into the first body cavity and an expanded condition in which the framing member is adapted for placement within the first body cavity, the framing member, when deployed into the expanded condition, having; a framing member body which includes a three-dimensionally bulbous portion defining a maximum body footprint in a lateral dimension and having longitudinally spaced proximal and distal body ends which are both longitudinally spaced from the maximum body footprint, a diameter of the bulbous portion being significantly smaller at the proximal and distal body ends than at the maximum body footprint, the proximal body end being attached to the outer surface of the target catheter wall, and a protrusion located at the distal body end, the protrusion having a maximum protrusion diameter which is significantly smaller than the diameter of the maximum body footprint, the protrusion including a plurality of protrusion body beams extending longitudinally distally from the distal body end of the bulbous portion, each protrusion body beam extending in a plane substantially parallel to, and laterally spaced from, the central framing member axis, each protrusion body beam having a distal body beam end which is laterally spaced from each other distal body beam end to define a protrusion aperture substantially concentric to the central framing member axis, the protrusion aperture permitting unobstructed access longitudinally therethrough to an interior of the bulbous portion via the distal body end; at least one target point carried by the framing member and adapted for placement adjacent the desired target site; and at least one target pathway attached to at least one target point, at least a portion of the target pathway extending through the target catheter lumen, and the target pathway being substantially spaced apart from the framing member body. - View Dependent Claims (14, 15, 16, 17)
