1. A puncture visualization device for a percutaneous puncturing procedure, the puncture visualization device comprising:
a guidewire, including:
a proximal section;
a distal section including a distal coil and a distal tip; and
an inner support engaged with the distal coil;
a needle including a needle lumen configured to receive the guidewire;
a lock configured to engage with the guidewire to inhibit relative motion between the guidewire and the needle;
an optical sensor, located at the distal tip of the guidewire, the optical sensor configured to be locked into a position by the lock to provide a distal field of view from a location within the needle and near a distal end of the needle for visualization to facilitate puncturing a target with the distal end of the needle; and
wherein the guidewire includes a first alignment feature that engages with the lock so as to define a length of the guidewire within the needle that locates the optical sensor at the distal tip of the guidewire at a location that is within the needle that is at a specified offset distance from a distal end of the needle to establish the distal field of view of the optical sensor to extend beyond the distal end of the needle.
