    • A urinary tract valve includes an expandable valve element (40) positionable within a bladder (12) of a patient via a urinary tract of the patient in a collapsed configuration. The expandable valve element is configured to transition from the collapsed configuration to an expanded configuration after being positioned within the bladder of the patient. The expandable valve element includes a ferromagnetic element that facilitates selective control of the expandable valve element with a magnetic field between an open position and a closed position when positioned within the bladder of the patient. In the closed position, the expandable valve element is configured to seal an internal urethral opening of the patient. In the open position, the expandable valve element is configured to allow urine to pass from the bladder of the patient, through an internal urethral opening of the patient and into a urethra of the patient.
    • 泌尿道瓣膜包括可膨胀的阀元件(40),该可膨胀阀元件(40)能够通过处于折叠构型的患者的尿道定位在患者的膀胱(12)内。 可膨胀阀元件构造成在定位在患者的膀胱内之后从收缩构型转变成扩张构型。 可膨胀阀元件包括铁磁元件,其在定位在患者的膀胱内时有助于在打开位置和关闭位置之间的磁场选择性地控制可膨胀阀元件。 在关闭位置,可膨胀阀元件构造成密封患者的内部尿道开口。 在打开位置,可膨胀阀元件构造成允许尿从患者的膀胱通过患者的内部尿道开口并进入患者的尿道。
