Abstract
A generally tubular device (e.g., a stent or catheter) for placement in a lumen of a patient's body is made by forming a depressed pattern in an external surface of a mold. The depressed pattern corresponds to a desired shape of the generally tubular device. A material is deposited in the depressed pattern for the material to form the generally tubular device conforming to the depressed pattern. The generally tubular device is separated from the mold.
