Abstract
A balloon catheter is provided having an expandable distal portion, said expandable portion having a proximal end, a distal end and distal expansion means, said expandable portion being adapted for expansion at its distal end, from its distal end to its proximal end. A stent delivery system is provided to facilitate introduction and placement of a stent, and includes a catheter having an expandable distal portion constructed and arranged for expanding the outer diameter of the catheter from a contracted state to an expanded state, said distal portion further comprising a balloon, and a stent positioned around the distal portion of the catheter around the balloon, said stent having a proximal end and a distal end and further having a contracted condition, said stent being sized in the contracted condition to closely surround the balloon in the contracted state, and being adapted to expand to an expanded condition from its distal end to its proximal end in response to expansion of the balloon member from its distal end.

17. A stent delivery system comprising:
-
a catheter comprising a proximal portion, a distal portion, a shaft and an expandable balloon located at the distal portion, said balloon having a proximal end and a distal end and being constructed and arranged for expanding the outer diameter of said balloon from a contracted state to an expanded state, said balloon being adapted for expansion from a distal end thereof, the balloon having an inflation port at a distal portion thereof, an inflation lumen in fluid communication with the inflation port for supplying an inflation fluid to the balloon; a radially expandable stent of generally cylindrical configuration positioned around said distal portion of said catheter around the balloon, said stent having a contracted condition, being sized in the contracted condition to closely surround the balloon in the contracted state, and further being expandable to an expanded condition; expansion means associated with the balloon for expansion of the balloon from the distal end thereof first and in a proximal direction, whereby said stent is adapted for expansion from a distal end thereof to a proximal end thereof in response to the expansion of the balloon and release of the stent by expansion of the balloon. - View Dependent Claims (18, 19)
