ABSTRACT:
Devices and methods for delivering stents to target vessel regions, including stent delivery through microcatheters to narrow cerebral arteries. One stent delivery device includes a stent having the distal region everted over the distal end of a delivery tube, having the everted stent distal end captured by a distal element of a elongate release member disposed through the delivery tube. The delivery tube can have a distal taper to a small profile distal end. The everted stent distal region can be captured between the release member distal element and the surrounding delivery tube distal region walls. The captured and everted stent can be distally advanced to a target site, followed by manipulating the release member to free the captured stent. Some devices utilize distal advancement of the release member while other devices use proximal retraction of the release member to free the captured stent distal end. Once released, the stent is free to self-expand or be expanded against the surrounding blockage and/or vessel walls. In some methods, a guide catheter or microcatheter is also included and disposed about the everted and captured stent to advance the stent, delivery tube, and release member to a location near the site to be stented. The devices and methods provide stent delivery not requiring an enclosing delivery sheath about the stent. The everted stent can thus have a very small distal profile enabling small diameter vessels to be crossed and treated.
