Patent ID: 7285109

Claim:
A reconfiguration device which comprises: an elongated balloon defining an axis and having an inner surface, said balloon being moveable between an inflated configuration wherein said balloon is substantially cylindrically shaped, and a deflated configuration wherein said balloon is collapsed onto said axis along predetermined fold lines in said balloon, said balloon further comprising: a midsection having a substantially cylindrical-shape in the inflated configuration, said midsection defining the axis; a first end portion attached to said midsection, said first end portion surrounding the axis and having a substantially conical-shape in the inflated configuration with a diameter decreasing in a direction away from said midsection; and a second end portion attached to said midsection, said second end portion surrounding the axis and having a substantially conical-shape in the inflated configuration with a diameter decreasing in a direction away from said midsection; and a first elastomeric member, a second elastomeric member and a third elastomeric member to guide said balloon into said deflated configuration upon deflation of said balloon, wherein: said first elastomeric member is attached to a first plurality of attachment points located on said inner surface of said balloon in said midsection; said second elastomeric member is attached to a second plurality of attachment points on said inner surface of said balloon in said first end portion; and said third elastomeric member is attached to a third plurality of attachment points on said inner surface of said balloon in said second end portion.
