Title (EN) PROXIMAL AND DISTAL RELEASE DELIVERY SYSTEM
(FR) SYSTÈME DE PLACEMENT À LIBÉRATION PROXIMALE ET DISTALE
Abstract:
(EN) Stent delivery device includes an inner member having a distal tip, a stent disposed over a stent receiving region of the inner member, an outer sheath slidable over the inner member, a stent sheath removably coupled to both the distal tip and a distal end of the outer sheath, and a stent expanding element attached to the distal tip and/or the distal end of the outer sheath. The stent expanding element is biased in an elevated position and aids expansion of the stent when the stent sheath is removed. The stent delivery device includes a proximal junction removably coupling the distal end of the outer sheath to the stent sheath, and a proximal junction removably coupling the stent sheath to the distal tip. Each of the proximal and distal junctions are separately actuatable to decouple the stent sheath from either the distal tip or the outer sheath.
(FR) La présente invention concerne un dispositif de placement de stent qui comprend un élément interne ayant une pointe distale, un stent disposé sur une région de réception de stent de l’élément interne, une gaine externe pouvant coulisser sur l’élément interne, une gaine de stent couplée de façon amovible à la fois à la pointe distale et à une extrémité distale de la gaine externe, et un élément d’extension de stent fixé à la pointe distale et/ou à l’extrémité distale de la gaine externe. L’élément d’extension de stent est sollicité dans une position élevée et facilite l’extension du stent lorsque la gaine de stent est retirée. Le dispositif de placement de stent comprend une jonction proximale couplant de façon amovible l’extrémité distale de la gaine externe à la gaine de stent, et une jonction proximale couplant de façon amovible la gaine de stent à la pointe distale. Chacune des jonctions proximale et distale peut être actionnée séparément pour séparer la gaine de stent de la pointe distale ou de la gaine externe.
