The invention provides a device for filtering emboli from blood flowing through a lumen defined by the walls of a vessel in a patient’s body, comprising a filter element and a self-expanding radial element associated with the filter element. The inventive station comprises a bracket that supports a blow mould, a stretch rod and means for controlling the movements of the stretch rod. The light emitting portion and light receiving portion are disposed so that the optical path of the light beam projected from the light emitting portion and received by the light receiving portion intersects the slide direction of the lens cover. Each delivery site receives from 2. Products produced with these methods and the use of the products are also provided. Deforming the profile involves comparing each zone of the component workpiece that has excess or insufficient thickness with elementary deformation configurations each in the form of a mesh portion and of points, the elementary deformation configurations being filed in a database, the database associating the parameters of the morphing function with each elementary deformation configuration.
