Abstract: This invention is directed to a medical device having a longitudinal axis, and including a handle and a catheter. The handle can include a body having a proximal end and a distal end, an actuator moveably coupled to the body, and a handle control member coupled to the actuator, wherein the actuator can be configured to move relative to the body to move the handle control member. The catheter can include a shaft having a proximal end and a distal end, wherein the proximal end of the shaft and the distal end of the body can be configured for releasable coupling. The catheter can also include a steering section located along the shaft and a catheter control member coupled to the steering section, wherein the catheter control member can be configured to move relative to the shaft to move the steering section relative to the longitudinal axis. The medical device can also include a securing member configured to move relative to at least one of the handle and the catheter to releasably couple the handle control member to the catheter control member.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
