Abstract
A stent delivery system comprises a catheter having a distal end and a proximal end, and a self expanding stent device having a compressed state and an expanded state and being positioned along the catheter and close to the distal end thereof. The stent delivery system further comprises a capsule enclosing the self-expanding stent device in its compressed state along substantially the whole length thereof. The capsule has an open distal end and a proximal end fixed to the catheter. Further, the capsule has at least one perforation extending longitudinally of said capsule from the distal end substantially to the proximal end thereof. The stent delivery system also comprises a balloon positioned within the capsule so as to break the capsule along said at least one perforation when inflated, whereby the stent device may expand to its expanded state, Thereafter the catheter with the broken capsule may be withdrawn from a duct in which the catheter has been introduced to a desired position.
