Stent and device for stent-delivery

Elongated device (20) for implantation of stents, for implantation of a stent (26), including the stent a tubular body having a distal region (46), comprising d ispositivo: one shaft (22) with a distal region (30), a proximal region and an opening or lumen (34) through, at least the distal region of the shaft; and an elongate release member (24) movable, having a proximal region, a distal region (40) and a distal end (42), wherein the distal region of the elongate release member (24) is arranged inside the opening of the distal region of the shaft (22), wherein the distal region of the release element (24) is dimensioned such that collaborates to hold, so that can be released, the distal region (46) the stent (26) between the distal region of the release element (24) and the distal region of the shaft (22), such that said release liberates only the coupling between the distal region of the release element (24) body and the distal region (46) of the stent (26) body by moving the release element which releases the entire stent (26) of the shaft (22).
