Abstract
An elongated guidewire assembly has a distal segment configured to be selectively maneuvered, along an elongated introducer assembly. The distal segment is configured to selectively transmit a tenting force from the elongated guidewire assembly to the first biological wall after the distal segment has contacted, at least in part, the first biological wall and the distal segment has been selectively protracted away from the distal introducer assembly.
Claims20
An apparatus for use with a first biological wall and a second biological wall of a patient, the second biological wall being positioned proximate to the first biological wall, and an elongated introducer assembly positioned proximate to the first biological wall, the apparatus comprising:
- an elongated guidewire assembly having a distal segment terminating at a distal puncture device, the distal segment including a distal length configured to extend beyond the elongated introducer assembly to contact, at least in part, a first outer surface of the first biological wall upon selective protrusion of the distal segment from a distal introducer exit portal of the elongated introducer assembly;
- wherein the elongated guidewire assembly is configured to transmit, through the distal length, a tenting force applied along the elongated guidewire assembly to the first biological wall after the distal length has contacted the first outer surface, wherein the tenting force transmitted to the first biological wall is insufficient to puncture the second biological wall.
An apparatus for use with a first biological wall of a patient, the apparatus comprising:
- an elongated introducer assembly positioned proximate to the first biological wall;
- and
- an elongated guidewire assembly having a distal segment terminating at a distal puncture device, the distal segment including a distal length configured to extend beyond the elongated introducer assembly and to be selectively protracted away from the elongated introducer assembly to contact, at least in part, a first outer surface of the first biological wall upon selective protrusion of the distal segment from a distal introducer exit portal of the elongated introducer assembly;

An apparatus for use with a first biological wall and a second biological wall of a patient, the second biological wall being positioned proximate to the first biological wall, the apparatus comprising:
- an elongated introducer assembly having a distal introducer exit portal configured to be selectively maneuvered and positioned proximate to the first biological wall;
- and
- an elongated guidewire assembly having a distal segment terminating at a distal puncture device configured to be selectively maneuvered along the elongated introducer assembly;
- wherein:
- the distal segment has a distal length configured to contact, at least in part, a first outer surface of the first biological wall in response to selective protracted movement of the distal segment and the distal puncture device away from the distal introducer exit portal after the distal introducer exit portal has been maneuvered proximate to the first outer surface of the first biological wall;
- and
- the distal segment is configured to selectively transmit a tenting force from the elongated guidewire assembly to the first biological wall in response to application of the tenting force along, at least in part, the elongated guidewire assembly after the distal length of the distal segment has contacted, at least in part, the first outer surface of the first biological wall, wherein the tenting force transmitted to the first biological wall is insufficient to puncture the second biological wall.
