Patent ID: 7722914

Claim:
A process for preparing a micromantled, drug-eluting endovascular stent, the stent comprising a scaffold and a stretchable, compliant microfibrous, non-woven mantle directly on the scaffold, comprising the steps of (1) dissolving at least polymer in at least one organic liquid comprising at least solvent to produce at least one uniform solution; (2) dissolving or dispersing at least one bioactive agent in each polymer solution; (3) transferring the product of step 2 to a syringe component of an electrospinning apparatus; and (4) electrostatically spinning at least one type of microfiber directly onto a metallic stent placed on a grounded, solid holding mandrill, wherein the grounded, solid holding mandrill is attached to a larger mandrill for concerted coaxial radial rotation and wherein the holding mandrill comprises a non-conductive polymeric rod, grounded through a partially embedded T-shaped metallic strip.
