摘要： The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to traction systems, and methods of use thereof, for endoscopic procedures such as tissue dissection. For example, a traction system may include a filament extendable along an outer surface of an endoscope with a distal end of the filament attachable to a medical device engaged with a target tissue of a body lumen.

摘要： Various embodiments are generally directed to a flexible elongate member (e.g., endoscopic accessory tool) positionable into and/or through selected anatomies, such as by generating images to position components of a flexible elongate member or to localize anatomic features, for instance. Some embodiments are directed to generating images with a plurality of imaging techniques to localize anatomic features and/or components of a flexible elongate member for one or more of inspection, orientation, and/or facilitating access to body passageways or lumens.

摘要： An example medical stent for treating a body lumen is disclosed. The example stent includes an expandable scaffold having a first end region, a second end region and an outer surface. The stent further includes a first fixation member coupled to the expandable scaffold and a biodegradable material disposed along the first fixation member at a first tissue engagement region. Further, the biodegradable material is designed to degrade from a first configuration in which the biodegradable material shields the first fixation member from a target tissue site to a second configuration in which the first fixation member is engaged with the target tissue site.

摘要： A tissue traction device having a segment defined along a limited extent about the perimeter of the tissue traction device and more flexible than surrounding regions of the tissue traction device. The tissue traction device is actuatable to bend along the more flexible segment thereof, generally in a direction of a side of the tissue traction device opposite the more flexible segment thereof. The tissue traction device may be formed from one or more flexible tubular elements, with the flexible segment along a limited extent about the perimeter of the one or more tubular elements. A tissue traction system may be configured to provide actuation medium, such as an inflation medium, to the tissue traction device to control movement of the tissue traction device. The tissue traction system may include one or more flexible tubular elements, a distal end of which forms the tissue traction device.

摘要： The present disclosure relates to medical devices that that include the following: a flexible elongate tube having a proximal end and a distal end configured to be directed toward an opening of a body lumen; a first lumen extending from the distal end of the tube proximally along the tube and having a fluid connection for a fluid source at its proximal end; a second lumen extending from the distal end of the tube proximally along the tube, the second lumen configured to accept a guidewire extending along the second lumen; and a wire filament extending along the elongate tube, a distal end of the filament connected to the distal end of the elongate tube, a proximal portion of the wire extending at least partially along the elongate tube, and a distal portion of the wire extending external to the elongate tube.

摘要： Sphincterotomes and methods for making and using sphincterotomes are disclosed. An example sphincterotome may include an elongate shaft having an outer surface and a distal end region. The sphincterotome may also include a sphincterotome wire assembly having a distal end coupled to the distal end region of the elongate shaft and a body portion extending along the outer surface of the elongate shaft. The sphincterotome wire assembly may be designed to shift the distal end region of the elongate shaft between a first configuration and a curved configuration. The body portion of the sphincterotome wire assembly may include a cutting region and a nonconductive region.

摘要： Medical systems are disclosed and may include an elongate member having a proximal end, a distal end, one or more channels extending between the proximal end and the distal end, and a handle operably coupled to the proximal end. The handle may include one or more ports in communication with the one or more channels. The medical systems may further include a docking station supporting the proximal end of the elongate member. The docking station may include a receiver adapted to receive and secure the handle and an adaptor guide unit having a distal end, a proximal end, and one or more passages formed therethrough, the one or more passages communicating with the one or more channels.

摘要： Embodiments of the invention are directed to a method of excising tissue including injecting fluid into the submucosa to raise targeted tissue. A first electrode is positioned below the targeted tissue within the injected fluid and a second electrode is positioned adjacent a surface of the raised targeted tissue opposite the first electrode. Electrical current is applied between the first and second electrodes and the targeted tissue is excised with the second electrode.
