the catheter is then removed from the body fig6 shows a catheter 600 for deploying stents in accordance with another embodiment of the invention the embodiment of fig6 has many components in common with the embodiment of fig1 and similar components are identified by the same reference numeral in both embodiments the embodiment of fig6 has a cylindrical carriage 605 mounted on the tube 102 the carriage has a plurality of annular depressions three are shown in fig6 610 a 610 b and 610 c configured to receive a stent as described below the depressions 610 all have the same length a as indicated in fig6 which is essentially equal to the length of the balloon 104 between the depressions 610 are barriers 620 a and 620 b the carriage 605 is made from an elastic material such as rubber the carriage 605 is slidable along the tube 102 by means of a wire 116 that extends along the length of the tube 102 from the proximal end 120 of the catheter to the carriage 605 the carriage 605 and the wire 116 form a positioner for moving a stent from a position in which it does not surround the balloon 104 to a position in which it surrounds.
