## Abstract

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.

## Claims

### Claim 1

A method comprising:
providing (i) a first stent and (ii) a second stent proximal to the first stent;
advancing the first stent against a guidewire into a lumen of a subject;
deploying the first stent in the lumen of the subject;
while maintaining the guidewire in the lumen of the subject subsequently to deployment of the first stent, advancing the second stent over the guidewire into the lumen of the subject; and
deploying the second stent in the lumen alongside the first stent, wherein an outer surface of the first stent is disposed against the guidewire and wherein the second stent surrounds the guidewire.
