AMBU A/S Injection Moulding Method for Endoscope
Summary
USPTO granted US Patent 12,605,046 B2 to AMBU A/S for an injection moulding method used to manufacture an elongate articulated bending section body for an insertion endoscope. The method involves a mould with sub-cavities distributed so each sub-cavity is separated from another by an odd number of sub-cavities without an external fluid inlet. The patent includes 14 claims and names Kaspar Mat Matthison-Hansen as the inventor.
What changed
USPTO issued Patent 12,605,046 B2 to AMBU A/S covering a moulding method for manufacturing articulated bending section bodies used in insertion endoscopes. The invention relates to a mould with strategically distributed sub-cavities where each sub-cavity is separated from adjacent sub-cavities by an odd number of sub-cavities lacking external fluid inlets, enabling segmented construction via hinge members.
Medical device manufacturers developing endoscopic or other articulated flexible medical instruments should review this patent when designing similar moulding processes for bending sections. The patent could affect competitive product development in the flexible endoscope market. AMBU A/S now holds enforceable patent rights for this specific moulding technique in the United States.

Abstract
A method for moulding an elongate articulated bending section body (4) for a medical device including a number of segments (7) interconnected via a number of hinge members (8). The method includes the use of a mould having a first number of sub-cavities where each of the sub-cavities has at least one external fluid inlet through which a liquified plastic material is injected into the mould. The sub-cavities are so distributed that each sub-cavity is separated from another sub-cavity by an odd number of sub-cavities without an external fluid inlet.
