The leaflets are attached to the frame between posts (8), with a free edge (3a, 3b) which can seal the leaflets together when the valve is closed under back pressure. The leaflets are created in a mathematically defined shape allowing good wash-out of the whole leaflet orifice, including the area close to the frame posts, thereby relieving the problem of thrombus deposition under clinical implant conditions.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the complete Patent AT-E401045-T1: [Translated] PRODUCTION PROCESS FOR HEART VALVE PROSTHESIS on the official website.", "downloadURL": "https://pubchem.ncbi.nlm.nih.gov/patent/AT-E401045-T1", "mediaType": "text/html", "title": "Official Data Source"}], "identifier": "https://healthdata.gov/api/views/dm8p-i74c", "issued": "2025-09-05", "keyword": ["chemistry", "innovation", "patent", "pubchem", "research"], "landingPage": "https://healthdata.gov/d/dm8p-i74c", "modified": "2025-09-06", "programCode": ["009:066"], "publisher": {"@type": "org:Organization", "name": "National Center for Biotechnology Information (NCBI)"}, "theme": ["NIH"], "title": "Patent AT-E401045-T1: [Translated] PRODUCTION PROCESS FOR HEART VALVE PROSTHESIS"}
