1. A stent-deployment assembly for use with a guidewire, comprising:
a. a single biliary stent; and
b. an elongated stent-conveyance tube comprising a guidewire-retaining segment that includes (i) respective distal and proximal apertures defining a guidewire-path therethrough, and (ii) a lengthways laterally-breachable portion,
wherein:
i. in a stent-advancement configuration, (A) the guidewire passes through the respective apertures so as to interiorly traverse the guidewire-retaining segment, (B) the stent is arranged to surround a stent-conveyance tube segment that is proximally displaced from the guidewire-retaining segment, for advancement of the stent together with the stent-conveyance tube along the guidewire into a body lumen of a human subject, and (C) the single stent is the only stent surrounding the stent-conveyance tube, and
ii. when the stent is disposed, in the stent-advancement configuration, at a target deployment location within the lumen, a proximal-direction withdrawal of the stent-conveyance tube is effective to cause the guidewire to breach the laterally-breachable portion of the guidewire-retaining segment so as to decouple the guidewire from the stent-conveyance tube without longitudinal displacement of the guidewire.
