    摘要: Test device for testing proper positioning of a radioactive radiation source for brachytherapy in an applicator tip, said device comprising

    a base device containing

    at least one, preferably at least two radiation detector(s),
    at least one, preferably at least two channel(s) for guiding radiation,
    at least one, preferably at least two opening(s) in the surface of the base device, each channel connecting one radiation detector with one opening in the surface of the base device, and

    an applicator holder comprising a cavity for receiving the applicator tip, including the radioactive radiation source, said applicator holder further including at least one, preferably at least two opening(s), which is/are arranged to match the opening(s) in the base device, and at least one, preferably at least two collimating channel(s), which channel(s) form(s) extensions of the channel(s) in the base device through the opening(s) in the base device, and which channel(s) connect(s) separate points of the cavity with the opening(s) in the applicator holder to guide and collimate radiation emitted in separate positions of the cavity to the respective radiation detector, one of which points is located at the distal end of the cavity. Preferably the applicator holder is separate from the base device, this embodiment allowing for sterilization of the holder before insertion of the applicator tip.

    摘要: An endoluminal device (20) for deployment in a body lumen includes a radially expandable stent (30), a graft attached to the stent, and a plurality of indicator members (50) affixed to the graft and adapted to form a normal pattern in response to a normal pressure differential and an abnormal pattern in response to an abnormal pressure differential across the graft. By forming different patterns at different pressure differentials, the indicator members enable the detection of a change in pressure which could be evidence of a leak. A system (70) for detecting a change in pressure differential includes the endoluminal device and an imaging system for displaying the indicator members. A method for detecting a change in pressure includes the steps of identifying the normal pattern, implanting the device, imaging the indicator members, and comparing the imaged pattern with the normal pattern to determine whether the normal pressure or an abnormal pressure differential exists.
