Temporary vascular scaffold with adjunctive energy delivery

A method of diminishing recoil and restenosis at a target site in a blood vessel, the method comprising:

• (a) advancing a medical device to the target site, wherein the medical device comprises:
• (i) a stent-like structure comprising a plurality of scoring members and a plurality of non-scoring members, wherein a number of the plurality of non-scoring members is greater than a number of the plurality of scoring members,
• (ii) an expandable element capable of expanding the stent-like structure against a wall of the body vessel, wherein the plurality of scoring members are configured to score and penetrate into a plaque and/or a wall of the blood vessel with focal forces,
• (iii) an inner shaft and an outer shaft, wherein a distal end of the stent-like structure is coupled to a distal end of the inner shaft and a proximal end of the stent-like structure is coupled to the outer shaft, wherein the expandable element is disposed in and operatively coupled to the inner shaft,
• wherein translation of the inner and outer shafts collapses the stent-like structure over a collapsed expandable element for removal from the body vessel;
• (b) gradually inflating the expandable element to press the stent-like structure against the wall of the blood vessel and expand the blood vessel;
• (c) applying an adjunctive energy source;
• (d) collapsing the expandable element to provide flow of blood distally;
• (e) leaving the stent-like structure expanded supporting the vessel wall for greater than 3 minutes;
• (f) collapsing the stent-like structure;
• and
• (g) removing the expandable element and the stent-like structure.
