摘要： An inflatable stent for use in the repair and maintenance of pipes such as water or gas supply pipes, or for use as a medical device comprises an inflatable portion having an inner and outer membrane. When inflated, the inner and outer membranes are radially spaced apart to define an annular space there between. The inner membrane defines a passage between a first and second end and the outer membrane defines a first diameter (D1) of the stent. The inner and outer membranes are connected by a plurality of connecting members in the annular space. End caps are disposed on the first and second ends of the stent which connect the inner and outer membranes. The inflatable portion further comprises an inflatable pipe or lumen engaging portion that defines a second, larger diameter (D2) of the stent, when inflated.
