Abstract

An inflatable medical device and method for the placement of a stent in a body passageway by means of a two stage expansion of the stent and for the delivery of medications to precise location in the passageway. The device includes a catheter shaft (14) having a plurality of lumens (13, 22, 28) disposed therein. The catheter shaft has a distal end adapted to be disposed within a vascular passageway.
An inflatable balloon is defined by a generally cylindrical wall and is adapted to receive inflation fluids. The balloon is disposed on the distal end of the shaft. An array of circumferentially arranged inflation conduits (40) is disposed in the wall. The conduits (40) are spaced from each other within the wall of the balloon whereby to form an annular array. An array of medication delivering conduits (25) can be disposed within the wall of the balloon. These conduits are adapted to deliver medications to predetermined locations within the body passageway being treated. A stent (30) is removably disposed around the exterior of the wall of the balloon and is expandable radially outwardly from a narrow insertion diameter to a larger second diameter by the expansion of the balloon (16) and then to a still larger third diameter by inflation of the inflation conduits (40) whereby to expand the body passageway and seat the stent.
