  • Heart valve
    Patent number: 12213878
    Abstract: A method of manufacturing a heart valve comprises: a step of injection moulding a first part of the heart valve from a first block-copolymer, wherein the injection moulding is performed at a temperature below an order-disorder transition temperature of the block copolymer, such that a phase structure is present in the molten block-copolymer; a step of injection moulding a second part of the heart valve from a second block-copolymer that is different to the first block-copolymer, by over-moulding over the first part to form an over-moulded structure, wherein the injection moulding is performed at a temperature below order-disorder transition temperatures for the first and second block copolymers, such that a phase structure is present in the molten second block-copolymer and remains present in the first block-copolymer; and a step of cooling the over-moulded structure, without heating it above the order-disorder transition temperatures between the step of injection moulding the second part and the step of cool

  • HEART VALVE
    Publication number: 20220125580
    Abstract: The invention relates to a method of manufacturing a heart valve, comprising: a step of injection moulding a first part (110) of the heart valve from a first block-copolymer, wherein the injection moulding is performed at a temperature below an order-disorder transition temperature of the block copolymer, such that a phase structure is present in the molten block-copolymer; a step of injection moulding a second part (114) of the heart valve from a second block-copolymer that is different to the first block-copolymer, by over-moulding over the first part (110) to form an over-moulded structure, wherein the injection moulding is performed at a temperature below order-disorder transition temperatures for the first and second block copolymers, such that a phase structure is present in the molten second block-copolymer and remains present in the first block-copolymer; and a step of cooling the over-moulded structure, without heating it above the order-disorder transition temperatures between the step of injection
