摘要： Apparatus (20) is provided for use with a guidewire (12). The apparatus includes a guide tube (22) having a guidewire-engaging portion (122) and a slit (28) extending proximally along a wall of the guide tube, from a distal end (32) of the tube, a proximal end (29) of the slit being located distally to a proximal end (30) of the tube. A first stent (52) surrounds the tube and is advanceable together with the tube into a lumen of a subject, the first stent being slidably advanceable off the distal end of the tube; and a second stent (54), proximal to the first stent, surrounding a proximal portion of the tube, and advanceable off the distal end of the tube into the lumen, and placed alongside the first stent subsequently to advancement of the first stent off the distal end of the tube. Other applications are also described.

摘要： A stent-deployment assembly includes an elongated stent-conveyance tube comprising a hollow longitudinal lumen configured to have a guidewire traverse longitudinally therethrough. The stent is arranged to surround a first stent-conveyance tube segment and a pushing tube surrounds a second stent-conveyance tube segment that is proximally displaced from the first stent-conveyance tube segment. A first locking member is engaged with the elongated stent-conveyance tube, and a second locking member includes a first portion arranged to transversely traverse the pushing tube and a second portion constrained within an interior volume of the stent by the presence of the first locking member.

摘要： A guide tube (220) has a guidewire-engaging portion (222) at a distal portion (260) thereof, a first stent (54) surrounding the guide tube, advanceable together with the guide tube into a subject's lumen, a guidewire (12) arranged (i) entering the guide tube from a distal-end (320) opening thereof, (ii) disposed in the guidewire-engaging portion, and (iii) passing out of the guide tube proximally to the guidewire-engaging portion, and a second stent (54), proximal to the first stent, surrounding a proximal portion (240) of the guide tube and the guidewire. The first stent is slidably deployable off the distal end of the guide tube upon the guidewire having laterally exited the guidewire-engaging portion, and the second stent is slidably deployable off the distal end of the guide tube subsequently to deployment of the first stent, without the guidewire having been moved proximally. Other applications are also described.

摘要： A stent-deployment assembly for use with a guidewire comprises a biliary stent and an elongated stent-conveyance tube comprising a guidewire-retaining segment that includes respective distal and proximal apertures defining a guidewire-path therethrough, and a lengthways laterally-breachable portion. In a stent-advancement configuration, the guidewire passes through the respective apertures so as to interiorly traverse the guidewire-retaining segment, and 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. 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 tube without longitudinal displacement of the guidewire.
