    • A steerable wire guide comprises first and second members interconnected to form a unitary composite structure. The members slide relative to each other such that the leading portion of the composite structure bends in a first or second direction. The composite structure comprises a soft body portion at its distal end and a rigid body portion at its proximal end. Various cross-sections are disclosed. In an alternate embodiment, the wire guide comprises a first guiding wire section, a wire loop section and a second guiding wire section, the wire component being folded back on itself to form a generally central wire loop section; and a tubular sheath surrounding the first guiding wire section and the second guiding wire section. The first and second members or guiding wire sections can be connected to a removable handle to facilitate control and maneuverability of the wire guide.
    • 可导向的导线器包括互连以形成整体复合结构的第一和第二构件。 这些构件相对于彼此滑动,使得复合结构的引导部分沿第一或第二方向弯曲。 复合结构包括在其远端处的软体部分和其近端处的刚体部分。 公开了各种横截面。 在替代实施例中,电线引导件包括第一引导线部分,线环部分和第二引导线部分,线部件自身折回以形成大致中心的线环部分; 以及围绕所述第一引导线部分和所述第二引导线部分的管状护套。 第一和第二构件或引导线段可以连接到可移除的手柄以便于导线器的控制和机动性。

    • A method and apparatus for introducing a first elongate medical device and short wire guide that are coupled together into a work site and remotely disconnecting them within the work site such that a secondary device comprising a catheter member can be introduced over the wire guide to the work site, and/or a second wire guide can be introduced to the work site via a passageway of the primary access device. A separating member may be provided to remotely separate the wire guide from the elongate medical device. In one example of the method, a wire guide and primary access device (e.g., a sphincterotome) is coupled to the wire guide and introduced via a duodenoscope into the biliary system. In another example of the method, a prosthesis, such as a valve or stent, is placed within the work site coupled to a wire guide which is remotely disconnected within the work site and a secondary device, such as a dilation balloon or second prosthesis, is introduced into the work site after the first delivery system is removed.

    • A method and apparatus for introducing a first elongate medical device and short wire guide that are coupled together into a work site and remotely disconnecting them within the work site such that a secondary device comprising a catheter member can be introduced over the wire guide to the work site, and/or a second wire guide can be introduced to the work site via a passageway of the primary access device. A separating member may be provided to remotely separate the wire guide from the elongate medical device. A system of indicia, such as radiopaque or viewable markers, permits the operator to monitor the relative alignment of the devices within the work site to determine when uncoupling has occurred. In one example of the method, a wire guide and primary access device (e.g., a sphincterotome) is coupled to the wire guide and introduced via a duodenoscope into the biliary system. After performing a first medical operation, the devices are uncoupled with the wire guide being left within the biliary system such that a secondary access device, such as a balloon, biopsy device, stent delivery catheter, dilator, etc., can be introduced to perform a second medical operation without a traditional over-the-wire exchange being required. In another example of the method, a prosthesis, such as a valve or stent, is placed within the work site coupled to a wire guide which is remotely disconnected within the work site and a secondary device, such as a dilation balloon or second prosthesis, is introduced into the work site after the first delivery system is removed.
