  • Patent number: 5395384
    Abstract: Instrument (1) designed, in particular, to permit the extraction of vein sections such as, for example, varices, including a two-piece supple cable (2) that is flexible and strong, both ends of which support a bullet shaped member (3).The cable (2) has a diameter substantially smaller than that of the vein to be extracted, and a length corresponding substantially to at least the length of the vein. The two cables are connected end to end by complementary connecting pieces. An olive-shaped member holds the connecting pieces within an internal bore. The bullet shaped members have a radial orifice for receiving a thread to assist in endo-stripping of the vein section.
