Bifurcated Balloon and Stent
First Claim
1. A stent for treatment of a vascular bifurcation, comprising a distal member and a proximal member, the distal member and the proximal member comprising tubular bodies, the distal member comprising first struts oriented in the proximal direction and the proximal member comprising second struts oriented in the distal direction, wherein at least one of the first struts is connected to at least one of the second struts on a first side of the stent, while on a second side of the stent, opposite the first side, one or more of the first struts are unconnected to any of the second struts and one or more of the second struts are unconnected to any of the first struts.

Abstract
A stent (22) for the treatment of a vascular bifurcation includes a distal member (40) and a proximal member (42), the distal member and the proximal member comprising tubular bodies, the distal member comprising first struts (64, 66) oriented in the proximal direction and the proximal member including second struts (54, 56) oriented in the distal direction, such that at least one of the first struts is connected to at least one of the second struts on a first side of the stent (46), while on a second side (48) of the stent, opposite the first side, one or more of the first struts are unconnected to any of the second struts and one or more of the second struts are unconnected to any of the first struts.

10. A method for manufacturing a stent for treatment of a vascular bifurcation, comprising:
-
providing distal and proximal members comprising tubular bodies, the distal member comprising first struts oriented in the proximal direction and the proximal member comprising second struts oriented in the distal direction; and connecting at least one of the first struts to at least one of the second struts on a first side of the stent, while not connecting one or more of the first struts on a second side of the stent, opposite the first side, to any of the second struts and not connecting one or more of the second struts on the second side to any of the first struts.

12. A method for treatment of a vascular bifurcation having a side vessel branching from a main vessel, the method comprising:
-
introducing into the main vessel in proximity to the side vessel a stent comprising a distal member and a proximal member, the distal member and the proximal member comprising tubular bodies, the distal member comprising first struts oriented in the proximal direction and the proximal member comprising second struts oriented in the distal direction, wherein at least one of the first struts is connected to at least one of the second struts on a first side of the stent, while on a second side of the stent, opposite the first side, one or more of the first struts are unconnected to any of the second struts and one or more of the second struts are unconnected to any of the first struts; advancing the stent into the side vessel, such that the first side of the stent is bent with the distal member partially within the side vessel, and the second side of the stent faces away from the side vessel; expanding the stent to support portions of the main vessel and the side vessel; and bending the unconnected first struts to support a further portion of the main vessel distal to the vascular bifurcation. - View Dependent Claims (13, 14)

15. A method for treatment of a vascular bifurcation having a side vessel branching away from an axis of a main vessel, the method comprising:
-
introducing into the main vessel in proximity to the side vessel a balloon having a main body and a protrusion; advancing the main body partially into the side vessel such that the protrusion faces into a portion of the main vessel distal to the bifurcation; expanding the main body, causing the main body to assume an expanded shape that bends within the bifurcation; and expanding the protrusion, causing the protrusion to extend along the axis of the main vessel into a portion of the main vessel distal to the bifurcation. - View Dependent Claims (16, 17)
