  • Publication number: 20050113851
    Abstract: A device is provided which can act as one component of an anastomosis-forming assembly, i.e. as an anastomosis button. The device comprises a plurality of elongate members having a first, introduction configuration in which they are substantially aligned with one another, and a second, use configuration in which they are disposed at an angle to one another. For example, there may be two such elongate members, which, in the use configuration, form a cross. The device comprises means, for example, a tensionable thread, for bringing the elongate members into the use configuration.

  • Publication number: 20040199087
    Abstract: A method is described of inserting guide wires into a lumen, for example into the human gastrointestinal tract. A guide wire structure is employed which comprises at least two guide wires each having a leading end portion which terminates in a leading end, the guide wires being connected to one another by a junction at or adjacent their leading ends, the guide wires have a first position in which the leading end portions are substantially parallel to one another, a second position in which the leading end portions are curved, and a third position in which at least one of the leading end portions forms a loop. The guide wire structure is steered through the gastrointestinal tract by selectively advancing or retracting a single guide wire or advancing more than one guide wire simultaneously, according to the path which is required to be followed.
