<p>A stent (10) and an introducer catheter (30) comprising carrier means (14) for delivering a bioactive substance at the implantation site of the stent (10). The carrier means (14) comprise channels (15) and/or ridges (16) that extend longitudinally along the stent (10) and define areas spaced from the internal wall of the introducer catheter that become coated with bioactive substance passed through the introducer catheter. Alternatively, the carrier means (14) may be defined by the introducer catheter (30), which may have the channels (35) and/or ridges (37) on its internal wall (36).</p> |
