Abstract

An instrument for the placement of a self-expanding stent in a body canal, which comprises an elongated inner tube having an outer tube disposed along its axis adapted to carry and retain a self-expanding stent adjacent its proximal end, and an arrangement for releasing the stent, in combination with at least one of the following components: (a) a location member for positioning and fixing the instrument so that the stent is released at a desired location in the body canal, and (b) a member for releasing the stent in a retrograde manner. A method for placing a self-expanding stent in a body canal is also disclosed.
