Abstract: An implantable medical device includes a lead body having a distal end and a proximal end, a lumen and at least one lead wire extending through the lumen. The lead wire has an outer surface and a polymeric coating on at least a portion of the outer surface of the lead wire. The coating includes a first structure having a first end proximate the outer surface of the lead wire and a second end opposite the first end. The second end is movable relative to the first end and relative to the lead wire.

Abstract: A medical device includes a tubular body having a distal end and a proximal end, a lumen extending through the tubular body from the distal end to the proximal end, a wire extending through the lumen from the distal end to the proximal end, and a polymeric coating. The wire has an outer surface. The polymeric coating is on at least a portion of the outer surface of the wire. The coating comprises a bulk material and a plurality of flexible microstructures disposed on the bulk material. The microstructures extend outwardly from a surface of the polymeric coating.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an elongate inner member having a guidewire lumen extending therethrough. An outer member may be disposed about the inner member. An inflation lumen may be formed between the inner member and the outer member. The medical device may be configured to have a first stiffness when the inflation lumen is free of inflation media and a second stiffness different from the first stiffness when inflation media is disposed within the inflation lumen. In addition, the inner member may include a collapsible region that is configured to deflect radially inward when inflation media is disposed within the inflation lumen.
