Percutaneous device for stable hemodialysis blood access
The granted patent US12016989B2 describes a percutaneous device designed for medical applications involving blood circulation. The device features a contact body made from a biocompatible material that interfaces with skin tissue, both internally and externally. It includes a tubular body that connects an artery to a vein, facilitating blood flow. Additionally, the device incorporates a blood removal tubular body that channels blood to an external circuit and a blood return tubular body that returns blood to the venous system. The design aims to ensure effective blood management in clinical settings.
Further specifications of the device highlight the materials used in its construction. The contact body can be made from hydroxyapatite or tricalcium phosphate, while the tubular body may consist of materials such as Gore-Tex®, expanded polytetrafluoroethylene (ePTFE), polyurethane (PU), or polyolefin-elastomer-polyester (PEP). The device also includes a connector that allows for separation of its upper and lower parts, enhancing its functionality. The lower part of the connector is equipped with puncture-type hollow bodies for both blood return and removal, which are securely attached to the respective tubular bodies. This design aims to improve the efficiency and safety of blood circulation procedures.
