Abstract
A balloon catheter includes an inflatable expander member for deploying a large diameter stent includes a plurality of balloon segments affixed to the distal end of a multi-lumen catheter body, the segments being selectively expansible in groups whereby the stent can be spread to conform to the blood vessel in which it is deployed while still permitting blood to perfuse through the spaces occupied by the uninflated ones of the segments. By using plural segments of smaller effective diameter, the composite expander can be made large enough to spread a collapsed stent without exceeding the burst strength of the individual balloon segments.
