Abstract: A beam block for laser cutting to produce a perforated tubular workpiece includes a tubular head section configured to be accommodated within an inner cavity of a semi-finished product during laser cutting, The tubular head section includes a recess at its first end configured to accept molten workpiece material into an inner surface of the tubular head section. A shaft section is located at a second end of the tubular head section. A plunger is configured to be reciprocated along an inner cavity of the tubular head section inner to the first end of the tubular head section to thereby eject molten workpiece material from the inner surface of the tubular head section. The plunger can be reciprocated periodically during laser cutting to eject molten workpiece material.

Abstract: A production system for producing a medical device from a tube includes a tube positioning device for positioning the tube. The tube positioning device is configured to hold the tube such that a portion of the tube extends from the tube positioning device along a longitudinal direction. A guiding device is used to guide the portion of the tube, and a laser cutting device is used to form the medical device from the portion of the tube. The guiding device comprises a plurality of bearing elements each configured to abut the portion of the tube and each having a convex curvature in a plane spanned by the longitudinal direction and a transverse direction perpendicular to the longitudinal direction.
