Device and method for tacking plaque to blood vessel wall

A method of further treating atherosclerotic occlusive disease in a blood vessel after a balloon angioplasty, comprising:

• advancing a plurality of tacks in a compressed state to a plaque dissection at a treatment area in a blood vessel after a balloon angioplasty has been performed at the treatment area, each of the tacks of the plurality of tacks comprising an annular band and a plurality of barbs on an outer annular periphery, and extending annularly around a longitudinal axis and extending longitudinally between a distal most end and a proximal most end which defines a tack width;
• expanding a first tack of the plurality of tacks to hold the plaque dissection against a wall of the blood vessel;
• and
• expanding a second tack of the plurality of tacks to hold the plaque dissection against the wall of the blood vessel, the second tack spaced away from the first tack a distance equal to at least the tack width of the second tack such that a portion of the treatment area between the first and second tacks that has been treated by the balloon angioplasty includes diseased tissue that is not covered by a tack.

• advancing a plurality of tacks to a treatment area in a blood vessel after a balloon angioplasty has been performed at the treatment area, each of the tacks of the plurality of tacks having a distal most end and a proximal most end along a longitudinal axis, and having a tack width defined by the distance between the distal most end and the proximal most end;
• expanding a first tack of the plurality of tacks against a wall of the blood vessel at the treatment area;
• and
• expanding a second tack of the plurality of tacks against the wall of the blood vessel at the treatment area, the second tack spaced away from the first tack a distance equal to at least the tack width of the second tack such that a portion of the treatment area between the first and second tacks that has been treated by the balloon angioplasty includes diseased tissue that is not covered by a tack.
