Medical device companies developing similar bifurcation treatment systems should conduct freedom-to-operate analyses to assess potential licensing needs.
What to do next
- Review patent claims to understand protected stent delivery technology
- Conduct freedom-to-operate analysis if developing competing bifurcation treatment devices
- Consider licensing opportunities if technology is relevant to product pipeline

Abstract
A stent delivery system for treating a bifurcated vessel includes a first elongate shaft with a first expandable member. A first stent having a side hole is disposed over the first expandable member. A second elongate shaft has a second expandable member. The second elongate shaft is slidably disposed under the proximal end of the first stent and extends out of the side hole. The first stent is fully crimped over a proximal portion and a distal portion of the first expandable member and a proximal portion of the second expandable member so as to prevent axial movement of the first stent relative to the first or second elongate shafts during delivery. Portions of the first or second expandable members may be pillowed to provide a protective barrier that prevents edges of the stent from catching on other objects.
