A stent mandrel fixture for supporting a stent during the application of a coating substance is provided. A method supporting a stent during the application of a coating substance is also provided.
What is claimed is: 1. A stent mandrel for partially covering a stent during an application of a coating composition, comprising: a mask made of or coated with a non-stick material; means for masking the stent so that an outer surface of the stent is exposed for coating by a coating substance, the
What is claimed is: 1. A stent mandrel for partially covering a stent during an application of a coating composition, comprising: a mask made of or coated with a non-stick material; means for masking the stent so that an outer surface of the stent is exposed for coating by a coating substance, the means for masking including an inflatable bladder in fluid communication with a pressure source; an engine connected to the mandrel and configured for rotating the stent during the application of the coating composition; and a coupling that decouples rotational motion supplied to the stent from the engine from pressure supplied to the bladder from the pressure source. 2. The stent mandrel of claim 1, wherein the mask is made from a thin material, and wherein the means for masking the stent includes means for masking both a luminal surface and a side surface of the stent using the mask. 3. The stent mandrel of claim 2, wherein the material is polytetraflouroethylene. 4. The stent mandrel of claim 2, wherein the thin material is capable of conforming to the shape of a stent strut when radially expanded into the stent strut. 5. The stent mandrel of claim 1, wherein the means for masking the stent includes means for masking a luminal surface of the stent by radially expanding the mask without also radially expanding the stent. 6. A stent support for stents that are to be partially coated with a coating composition, comprising: a mandrel base; a masking element; a lever; a rod having a longitudinal axis and configured to be moved in or out of the base; and means for placing the masking element on at least a luminal surface of a stent when the rod is at least moved parallel to its longitudinal axis and out of the base including a coupling between the rod and the lever, wherein the coupling converts rotational motion of the lever about an axis perpendicular to the longitudinal axis to motion of the rod parallel to the longitudinal axis.
