1. An implantable surgical device having a deployed shape and an undeployed shape, said device comprising:
- a. an elongated flexible inflatable portion; and
b. an elongated flexible and substantially inextensible band portion having a distal end, a proximal end and a longitudinal axis therebetween, said band portion being attached to said inflatable portion along an inner face thereof, wherein when said device is in its undeployed shape said band portion has a concave cross section along a majority of its longitudinal axis, taken perpendicular to said longitudinal axis, and wherein when said device is in its deployed shape said band portion has a substantially linear cross section along a majority of its longitudinal axis.

Abstract
An implantable surgical device having a deployed shape and an undeployed shape. The device includes an elongated flexible inflatable balloon portion and an elongated flexible and substantially inextensible band portion. The band portion has a distal end, a proximal end and a longitudinal axis therebetween. The band portion is attached to the balloon portion along an inner face thereof. When the device is in its undeployed shape at least a portion of the band portion has a concave cross section taken perpendicular to the longitudinal axis.
