Claims10
A device for positioning an apparatus introduced into an arterial network via an endoscope in a bifurcated vessel having two daughter vessels, only one of which is to be treated, the device comprising:
- a tubular element having an asymmetrical lateral extension for angular positioning of the apparatus;
- and
- a detachable sleeve which, at the time of the introduction into an artery, surrounds the tubular element and the lateral extension to maintain the lateral extension in a folded position against the tubular element, the detachable sleeve being attached to a thread, wherein the asymmetrical extension can be released by pulling on the thread and by thus withdrawing the sleeve.
A positioning device for use with a stent having a beveled end comprising:
- a tubular element and an asymmetrical extension foldably connected to the tubular element, the asymmetrical extension extending laterally outwardly from the tubular element unless held in another position by a retainer;
- and
- a retainer for selectively holding and releasing said asymmetrical extension, wherein the retainer is a detachable sleeve extending around the tubular element and the asymmetrical extension.
