Abstract
Methods and apparatus are disclosed for customizing an elution rate of a stent. The stent includes a hollow strut that forms the stent, the hollow strut defining a lumenal space, a drug formulation disposed within the lumenal space of the hollow strut, and at least one side port for eluting the drug formulation in vivo. When the stent is in the radially expanded configuration the hollow strut is deformable from a first configuration that has a first elution rate for the drug formulation to a second configuration that has a second elution rate for the drug formulation. The second elution rate is faster than the first elution rate. The hollow strut deforms from the first configuration to the second configuration upon application of an applied pressure above a predetermined threshold.
