Claims19
A medical device with a balloon-stent assembly comprising a balloon expandable stent, a balloon within the balloon expandable stent, and a breakable tether that links the balloon expandable stent and the balloon;
- wherein the breakable tether does not wrap around the stent and is not a restraining tether that restrains an expansion of the stent;
- wherein the breakable tether does not wrap around the balloon;
- and
- wherein the breakable tether is so configured that, while the balloon expandable stent is being expanded by the balloon and after the balloon expandable stent has been expanded by the balloon and has been placed in a position in a tissue lumen or a channel within a tubular tissue structure, the breakable tether does not break apart;
- but while the balloon is being moved away from the already-placed balloon expandable stent or after the balloon is moved away from the already-placed balloon expandable stent, the breakable tether breaks apart without disrupting the position of the already-placed balloon expandable stent.
