Expansion Device for Treatment of Vascular Passageways
First Claim
Patent Images
1. A system for delivering an expansion device to a treatment location within a patient'"'"'s body, the system comprising:
- an elongate shaft having a distal end portion; and
an expansion device coupled to the distal end portion of the elongate shaft and moveable between a collapsed configuration and an expanded configuration, the expansion device having a distal end and a proximal end, and the expansion device comprising an inner expandable member and a plurality of outer expandable members,wherein the plurality of outer expandable members comprise at least five outer expandable members that at least partially surround the inner expandable member and when the expandable member is in the expanded configuration, gaps between adjacent outer expandable members provide perfusion passageways across the expansion device.

Abstract
A delivery system for delivering an expandable member to a treatment location includes an elongate shaft and an expandable member coupled to a distal end of the elongate shaft. The expandable member is moveable between a collapsed configuration and an expanded configuration, and has an inner expandable member and a plurality of outer expandable members that at least partially surround the inner expandable member.

16. An expansion device comprising:
-
an elongate shaft having a distal end portion; an inner balloon member coupled to the distal end portion of the elongate shaft and moveable between a collapsed configuration and an expanded configuration; and a plurality of outer balloon members that at least partially surround the inner balloon member, each of the outer balloon members being moveable between a collapsed configuration and an expanded configuration, the outer balloon members having a generally circular cross-sectional shape when in the expanded configuration, wherein, when the inner balloon member and at least some of the outer balloon members are in the expanded configuration within a body lumen, a plurality of passageways are provided between an outer surface of the expanded inner balloon member and an inner surface of the body lumen to allow blood to flow through the passageways and across the expansion device. - View Dependent Claims (17, 18, 19, 20, 21)

22. A method for delivering an expandable member through the vasculature of a patient comprising:
-
providing an expandable member at a distal end of an elongate shaft, the expandable member having a distal end and a proximal end, the expandable member comprising an inner expandable member and a plurality of outer expandable members at least partially surrounding the inner expandable member; delivering the expandable member to a treatment site; expanding the inner expandable member in a passageway of the body of the patient; expanding the plurality of outer expandable members in the passageway; and permitting blood to pass through a plurality gaps formed between an inner surface of the passageway and outer surfaces of the inner and outer expandable members.
