1. An apparatus for an ancillary assembly having an exit portal configured to be positioned proximate to a first tissue portion and a second tissue portion of a biological wall of a patient, the apparatus comprising:
an elongated guidewire assembly having a distal-shaped section including a distal puncture tip, a first linear portion extending from the distal puncture tip to a first inflection portion, an intermediate portion extending from the first inflection portion to a second inflection portion, a second linear portion extending from the second inflection portion towards a proximal end of the elongated guidewire, the elongated guidewire assembly configured to be received in an elongated lumen of the ancillary assembly; and
the distal puncture tip configured to be deployed from the exit portal of the ancillary assembly in such a way that the elongated guidewire assembly, in a relaxed deployed condition, forms a deployed distal-shaped section having a distal curve and a relative offset between the first inflection portion and the second inflection portion after the elongated guidewire assembly is in the deployed condition, such that, in the deployed condition the distal puncture tip does not extend proximally beyond a plane orthogonal to a longitudinal axis of the second linear portion and passes through the second inflection point.
