摘要： 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.

摘要： An endoscopic ultrasound-guided system and method for monitoring the location of a device contained within intraluminal and extraluminal regions of a patient is described. The endoscopic ultrasound-guided system includes a linear echoendoscope, a device, and a wire guide. The device and wire guide contain echogenic surfaces which enable transducers placed at the distal end of the linear echoendoscope to ultrasonically monitor the location of the devices. When the echogenic surface of the device encounters incident ultrasound waves emitted from a series of linear array transducers, a real-time ultrasonic image of the device is generated as the incident ultrasound waves reflect off the echogenic surfaces and propagate back towards the transducers. The surgeon receives the real-time ultrasonic image of the device and then can determine the location of the device within the intraluminal or extraluminal region of the patient. After determining the location of the device, the surgeon can adjust the path of the device to ensure it is guided to the target site.
摘要翻译： 描述了内窥镜超声引导系统和用于监测包含在患者的腔内和腔外区域内的装置的位置的方法。 内窥镜超声引导系统包括线性回声内窥镜，装置和线引导件。 该装置和导线导轨包含回声表面，使得放置在线性回声内窥镜的远端处的换能器能够超声监视装置的位置。 当装置的回波表面遇到从一系列线性阵列换能器发射的入射超声波时，随着入射超声波从回波表面反射并向换能器传播，产生该装置的实时超声波图像。 外科医生接收设备的实时超声波图像，然后可以确定装置在患者的腔内或管腔内的位置。 在确定设备的位置后，外科医生可以调整设备的路径，以确保其被引导到目标位置。

摘要： A stent introducer apparatus includes a handle having a housing and a rotatable reel. An inner stent carrier having a proximal end and a distal end is provided, with the proximal end being connected to the housing of the handle. An outer sheath movably disposed about the inner stent carrier and having a proximal end and a distal end is provided, with the proximal end being connected to the reel of the handle. Rotation of the reel relative to the housing peels the outer sheath away from the inner stent carrier so as to move the outer sheath proximally relative to the inner stent carrier, thereby exposing the distal end of the inner stent carrier. The inner stent carrier has a stent carrying portion at its distal end to carry a stent that is deployed when the distal end of the inner stent carrier is exposed.

摘要： The present invention provides apparatus and methods for performing endoscopic mucosal resection and endoscopic submucosal dissection of tissue. In a first embodiment, a catheter having proximal and distal ends and a balloon disposed near the distal end of the catheter is provided. A portion of the distal end of the catheter is configured to be inserted beneath a section of mucosal tissue having a lesion, and the balloon is configured to be inflated to lift the mucosal tissue in an upward direction, thereby facilitating removal of the tissue comprising the lesion. Optionally, a surgeon may advance a needle knife through the catheter to further incise submucosal tissue while the balloon is in the inflated state. If desired, a flushing fluid may be provided to a target site during the procedure.
