A method for removing a solvent from a stent, comprising the steps of: rotating the stent above a nozzle exit portion of a dryer to cause a gas produced by the dryer to affect a removal rate of solvent from the stent, the gas being produced by the following steps: supplying a gas to the dryer, the gas being delivered through a circular conduit such that the gas has an input mean flow direction (V ∞) into the dryer, characterized in that, the method further comprises the steps of: decelerating the gas as it encounters a first chamber of the dryer, the first chamber presenting the gas with a first enlarged space arranged such that the gas is expanded in a direction perpendicular to the input mean flow direction, after the gas has been expanded in a direction perpendicular to the input mean flow direction, accelerating the expanded gas by forcing the gas to make a 90° turn and flow substantially parallel to the input mean flow direction through a linear array of apertures (50, 52), the array being arranged along a direction perpendicular to the mean flow direction, the gas entering a second chamber, and decelerating, and then accelerating the gas as it fills the second chamber, the second chamber presenting the gas with a second enlarged space, followed by a narrowed space downstream of the second enlarged space and the nozzle exit downstream of the narrowed space; wherein the gas produces a uniform heat transfer from the gas to the stent over the entire surface of the rotating stent. rotating the stent above a nozzle exit portion of a dryer to cause a gas produced by the dryer to affect a removal rate of solvent from the stent, the gas being produced by the following steps: supplying a gas to the dryer, the gas being delivered through a circular conduit such that the gas has an input mean flow direction (V ∞) into the dryer, characterized in that, the method further comprises the steps of: decelerating the gas as it encounters a first chamber of the dryer, the first chamber presenting the gas with a first enlarged space arranged such that the gas is expanded in a direction perpendicular to the input mean flow direction, after the gas has been expanded in a direction perpendicular to the input mean flow direction, accelerating the expanded gas by forcing the gas to make a 90° turn and flow substantially parallel to the input mean flow direction through a linear array of apertures (50, 52), the array being arranged along a direction perpendicular to the mean flow direction, the gas entering a second chamber, and decelerating, and then accelerating the gas as it fills the second chamber, the second chamber presenting the gas with a second enlarged space, followed by a narrowed space downstream of the second enlarged space and the nozzle exit downstream of the narrowed space; supplying a gas to the dryer, the gas being delivered through a circular conduit such that the gas has an input mean flow direction (V ∞) into the dryer, characterized in that, the method further comprises the steps of: decelerating the gas as it encounters a first chamber of the dryer, the first chamber presenting the gas with a first enlarged space arranged such that the gas is expanded in a direction perpendicular to the input mean flow direction, after the gas has been expanded in a direction perpendicular to the input mean flow direction, accelerating the expanded gas by forcing the gas to make a 90° turn and flow substantially parallel to the input mean flow direction through a linear array of apertures (50, 52), the array being arranged along a direction perpendicular to the mean flow direction, the gas entering a second chamber, and decelerating, and then accelerating the gas as it fills the second chamber, the second chamber presenting the gas with a second enlarged space, followed by a narrowed space downstream of the second enlarged space and the nozzle exit downstream of the narrowed space; decelerating the gas as it encounters a first chamber of the dryer, the first chamber presenting the gas with a first enlarged space arranged such that the gas is expanded in a direction perpendicular to the input mean flow direction, after the gas has been expanded in a direction perpendicular to the input mean flow direction, accelerating the expanded gas by forcing the gas to make a 90° turn and flow substantially parallel to the input mean flow direction through a linear array of apertures (50, 52), the array being arranged along a direction perpendicular to the mean flow direction, the gas entering a second chamber, and decelerating, and then accelerating the gas as it fills the second chamber, the second chamber presenting the gas with a second enlarged space, followed by a narrowed space downstream of the second enlarged space and the nozzle exit downstream of the narrowed space;
