Patent ID: 7311719

Claim:
An inflatable medical device comprising: a support member having a longitudinal axis, a proximal portion, a central portion and a distal portion wherein said central portion has a smaller diameter than said proximal and distal portions, wherein each portion has a substantially uniform diameter; and an inflatable balloon including a proximal portion having an inner surface thereof bonded to an outer surface of the proximal portion of the support member, a distal portion having an inner surface thereof bonded to an outer surface of the distal portion of the support member, a first expanding portion extending distally from the proximal portion of the inflatable balloon, and a second expanding portion extending proximally from the distal portion of the inflatable balloon, wherein each of the expanding portions includes a plurality of rigid members arranged along an inner surface thereof to define a predetermined shape of the inflatable balloon when the inflatable balloon is fully inflated and the rigid members of the first expanding portion are spaced apart from the rigid members of the second expanding portion, wherein the plurality of rigid members is repositionable between a first position and a second position.
