    • 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. 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 stylet wire assembly is disclosed which sealingly engages the proximal end of a medical catheter, and allows the unobstructed injection or evacuation of fluids into or from a patient's body through the catheter while the stylet wire is in place therein. The disclosed assembly includes a stylet wire and a housing. The housing has a catheter fluid communication port at its distal end and anchors the stylet wire into its closed proximal end with the stylet wire extending through the catheter fluid communication port at the distal end of the housing. This anchoring is accomplished by means of a plug which has been injection molded about the crimped proximal end of the stylet wire and bonded to the distal end of the remainder of the housing. An external fluid communication port allows for fluid communication into and out of said housing in transverse orientation relative to the axis of said stylet wire within said housing and distally of the anchoring of the stylet wire into the proximal end of the housing. The distal end of the housing sealingly engages the proximal end of a medical catheter in fluid communication between the catheter fluid communication port of the housing and the fluid conduit of the catheter by means of the combined effect of a female threaded portion which advances over the end of the catheter and an inner sealing tubular portion which advances within the fluid conduit of the catheter. A fluid conduit provides fluid communication within the housing between the catheter fluid communication port and the external fluid communication port. Upon removal of the stylet wire assembly, the proximal end of the medical catheter can be connected directly to an infusion/evacuation tube without the need for sealing the second port of the standardly used T-fitting.

    • A method and device for incising tissue from the gastrointestinal tract are described. The device is an electrosurgical cutting device. The electrosurgical cutting device includes a catheter and multiple electrically conductive cutting wires extending through a lumen of the catheter. The wires are movable between a retracted position and an extended cutting position. The wires form a divergent configuration in the extended cutting position. The electrosurgical cutting device may be loaded into an endoscope, which is then maneuvered to the target tissue site to be incised. Manipulating a handle assembly extends the wires into a divergent cutting configuration. Electrical current is applied causing the wires to incise tissue from the target site.

    • A stent introducer apparatus includes a handle with a proximal end and a distal end and having a portion that is coaxially slidable from the distal end to the proximal end and vice versa. A catheter having a proximal end and a distal end is provided with a pair of open end slits each of which defines a tab that is connected to the slidable portion of the handle. A guide wire is disposed within the catheter and has a proximal end and a distal end such that when the slidable portion of the handle is moved from the distal end to the proximal end, the distal end of the guide wire is exposed. The guide wire has a stent carrying portion at its distal end to carry a stent that is deployed when the distal end of the guide wire is exposed.

    • A clip device for hemostasis includes a clip having a proximal end portion and at least two arm portions extending from the proximal end portion and provided with a tendency to open. A sliding ring is provided for closing the arm portions of the clip. A first retainer is attached to the clip, and the first retainer is configured to be releasably secured to a second retainer that may be attached to an operating wire or a torque cable. In operation, the clip device is advanced to a target site in a body cavity. An outer sheath is retracted to expose the clip, causing the arms to open. An inner sheath is advanced distally, causing the sliding ring to advance distally to close the arms of the clip. Stop elements may be disposed on the clip to ensure that he sliding ring is not advanced distally over the clip. Then, the first retainer is disengaged from the second retainer. Various mechanisms are disclosed to permit the first and second retainers to disengage from one another. The first retainer, attached to the clip, is left inside the patient's body cavity, while the second retainer is removed from the patient.

    • A method of fabrication of a sphincterotome, such as a papillotome, for surgical cutting using an electrically conductive cutter wire. The sphincterotome includes a multi-lumen tubular member, with one lumen having an electrical conductor disposed therein, and the other lumen having a reinforcing wire disposed therein. The reinforcing wire is preferably rectangular in cross-section, providing a greater moment of inertia in a resisting axis than in a bending axis. Accordingly, the cutting edge of the cutting wire may be oriented to the 12 o'clock position of the papillary orifice to avoid injury to the duodenal wall or pancreatic duct in the patient, and to maintain the cutting edge in a predetermined cutting plane. Fluoroscopic indicating stripes may be provided at the distal end of the sphincterotome.
    • 一种用于使用导电切割线进行手术切割的括约肌切开术例如乳头切开术的方法。 括约肌切开术包括多腔管状构件,一个管腔具有设置在其中的电导体,另一个内腔具有设置在其中的增强线。 增强线的横截面优选为矩形,在抗弯轴上提供比弯曲轴更大的惯性力矩。 因此,切割线的切割边缘可以定向到乳头孔的12点位置,以避免对患者十二指肠壁或胰管的损伤,并将切割刃保持在预定的切割平面中。 可以在括约肌切开术的远端设置透视指示条纹。
