    • An implantable vessel occlusive device and method for occluding a vessel are described, for example to occlude the urethra or bladder neck. The devices and methods described utilize an occlusive member connected to a control mechanism. The occlusive member is reversibly changed from a non-occlusive condition to an occlusive condition, for example by depressing an activation button contained within a resilient, elastomeric cover surrounding the control mechanism. In the occlusive position, an initial tension is applied to the occlusive member through a tensioning suture. The tension is translated into an occlusive pressure applied to the urethra or bladder neck that is sufficient to prevent urinary leakage. The non-occlusive position can be obtained by depressing the de-activation button. The occlusive member is constructed to allow elution of drugs, such as may be required to combat infection or tissue encapsulation from its surface.
    • 描述了用于闭塞血管的可植入血管闭塞装置和方法,例如用于闭塞尿道或膀胱颈。 所描述的装置和方法利用连接到控制机构的闭塞构件。 例如通过压下容纳在围绕控制机构的弹性的弹性盖内的激活按钮,闭塞构件可逆地从非闭塞状态变为闭塞状态。 在闭塞位置中,通过张紧缝合线向闭塞构件施加初始张力。 张力转化为施加于尿道或膀胱颈部的足以防止漏尿的闭合压力。 通过按下去激活按钮可以获得非闭塞位置。 封闭构件被构造成允许药物洗脱,例如可能需要与其表面的感染或组织封装作斗争。
