Endovascular device having a stent

An intravascular medical device, comprising:

• a stent having a lumen therethrough and having a small dimension for placement into a delivery device for delivery to a deployment site in a vessel of a patient and being expandible thereat to an enlarged dimension, and
• at least one inflatable member secured to said stent and having an inflation lumen extending therefrom, said at least one inflatable member being sufficiently small in a deflated state to be placed into said delivery device for delivery to said deployment site;
• and
• said at least one inflatable member being affixed to said stent along an outer surface thereof and is disposed circumferentially therearound, and is inflatable to press radially outwardly against a wall of said vessel in sealing engagement therewith.

An intravascular medical device, comprising:

• a stent having a lumen therethrough and having a small dimension for placement into a delivery device for delivery to a deployment site in a vessel of a patient and being expandible thereat to an enlarged dimension, and
• at least two inflatable members secured to said stent and having respective inflation lumens extending therefrom, said at least two inflatable members being sufficiently small in a deflated state to be placed into said delivery device for delivery to said deployment site;
• and
• said at least two inflatable members being affixed to an outer surface of said stent and is disposed circumferentially therearound spaced from each other, and being inflatable to press radially outwardly against a wall of said vessel in sealing engagement therewith at spaced locations.

• at least one inflatable member secured to said stent and having an inflation lumen extending therefrom, said at least one inflatable member being sufficiently small in a deflated state to be placed into said delivery device for delivery to said deployment site;
• and
• said at least one member being affixed to an inner surface of said stent to expand radially inwardly upon inflation and engage and press against either itself or another said at least one inflatable member to occlude said lumen of said stent.
