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 system of indicia, such as radiopaque or viewable markers, permit 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.

A needle knife sphincterotome comprising a tensioning filament for positionally adjusting its distal end and a needle knife configured for tissue aspiration. The sphincterotome includes an actuatable handle attached to an elongate shaft having a needle knife near its distal end. The tensioning filament includes proximal and distal attachments and is configured such that actuation of the handle introduces a tension in the tensioning filament that bends, arches, or otherwise deforms the distal end of the sphincterotome shaft.

A method of occluding a fistula in a patient is provided. The method includes inserting a placement member having a coupling structure, such as a wire guide having a loop at one end, through the primary opening of a fistula and at least partially into the fistula tract; connecting the coupling structure to a medical device, such as a plug, graft, or other occluding member; and inserting the medical device into the fistula by pulling the placement member through the fistula until the medical device contacts the interior wall of the fistula. Medical devices and systems for occluding fistulas are also provided.

A medical device for allowing a physician to unhand a scope or other instruments while maintaining control of the scope or other instruments during a medical procedure. The medical device includes at least one docks and a harness for attaching the dock to the physician's body. The harness can be adjustable, or sized to fit a specific physician. During a procedure, a physician outfitted with the medical device can place a scope and/or other instrument in the dock(s). Once the scope and/or other instrument is placed in the dock(s), the physicians hands are free to perform other procedures, while the physician continually controls the relative position of the scope with respect to the physician or the patient.

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.
