    Abstract: This disclosure relates generally to the field of devices and procedures for forming an opening between adjacent tissue structures. For example, in an embodiment, a system for forming an opening between body lumens may include a delivery catheter. A first access element may be configured to be positioned against a first body lumen disposed about a distal end of the catheter. A second access element having an outer diameter that substantially matches an outer diameter of the first access element may be disposed about the distal end of the catheter. The second access element may be configured to be positioned against a second body lumen and axially aligned with the first access element. A filament may be electrically coupled to one or both of the first and second access element.

    Abstract: A bipolar ablation device for treatment of a stenosis within an implanted metallic stent may include an elongate shaft slidably disposable within an endoscope, the elongate shaft including at least one electrode configured to form a first pole of the bipolar ablation device, and an electrode lead slidably disposable within the endoscope. The electrode lead may be configured to electrically engage the implanted metallic stent to form a second pole of the bipolar ablation device. The elongate shaft may be positionable within a lumen of the implanted metallic stent.

    Abstract: The present disclosure relates generally to the field of medical devices and medical device delivery. In particular, the present disclosure relates to medical devices, systems, and methods for delivering a barrier device within a body lumen of a patient, such as the GI tract. For example, a barrier device may include a distal self-expanding stent. A tubular barrier may have a proximal end, a distal end, and a lumen extending therethrough. The distal stent may be disposed at the distal end of the tubular barrier. An anchoring self-expanding stent may be disposed at the proximal end of the tubular barrier.

    Abstract: An implantable device having an adjustable passage therethrough. The passage may be adjustable to occlude or otherwise to regulate access or flow of materials therethrough. An elongated element may be inserted into the passage when in a closed configuration to selectively open the passage. For instance, the implantable device may be a tubular device with a twisted region closing the passage therethrough, and the elongated device may be configured to engage such twisted region and to be rotated to untwist the closed region. An additional tubular device with a passage therethrough may be inserted into the passage of the implantable device to hold open the passage for a selected period of time.
