A steerable wire-guide comprises an elongate member having a longitudinal axis. The elongate member comprises a leading portion and a body portion. The leading portion comprises a loop and the body portion comprises a first wire and a second wire. The first and second wires are movable relative to each other such that relative movement of the first wire with respect to the second wire directs the leading portion in a first direction, which is at an angle relative to the longitudinal axis, and relative movement of the second wire with respect to the first wire directs the leading portion in a second direction different from the first direction.

Steerable loop tip wire-guide

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.

System and method for introducing multiple medical devices

A method and apparatus for releasably securing a wire guide to an elongate medical device for introduction into a work site with the bodily lumen of a patient. An elongate engagement member is configured to engage the wire guide while it is coupled to the elongate medical device and is configured so as to prevent relative movement between the wire guide and the elongate medical device.

Distal wire stop

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.

Articulating steerable wire guide

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 wire guide has first and second portions with first and second diameters, respectively. A resilient loop positions a distal end of the wire guide adjacent another section of the wire guide. A closure member comprising at least one attachment tab maintains the distal end in a fixed position relative to the remainder of the wire guide. A covering may be positioned around one or more parts of the wire guide.

Loop tip wire guide

A wire guide has first and second portions with first and second diameters, respectively. A resilient loop positions a distal end of the wire guide adjacent another section of the wire guide. A closure member maintains the distal end in a fixed position relative to the remainder of the wire guide. A covering may be positioned around one or more parts of the wire guide.
