Abstract:
1. A method of invert bonding of a balloon comprising: bonding a sheath balloon to a stent at a first bond location, where the sheath balloon has first surface and a second surface, where the bonding at the first bond location is between the stent and a portion of the first surface, where the first surface faces the stent and where the stent is configured to pass acoustic signals through an acoustic channel that is independent of an inflation channel of the balloon; pulling the sheath balloon from an unbounded end over the first bond to a chosen second bond location so that the first surface faces away from the stent forming an inverted bond at the first bond location; bonding the sheath at the second bond location where the bonding at the second bond location is between the stent and a portion of the second surface; and coupling the acoustic channel to at least one of a microphone or a receiver at one end of the acoustic channel.
