Abstract: According to exemplary embodiments of the present disclosure, devices, systems, and methods for endoscopic procedures may include an end effector of a grasping system having a first arm and a second arm. The first and second arms may extend from a common proximal joint. The first and second arms may be formed of a self-expanding material and may have a spring force to set the arms in an unconstrained open position. The first and second arms may have an arc shape such that a distal tip of each first and second arm are configured to close as the first and second arms are actuated to a constrained closed position. A catheter may include a locating element at a distal end of a flexible tube. The locating element may be configured for locating the grasping system.

Abstract: According to exemplary embodiments of the present disclosure, devices, systems, and methods for pyloric occlusion in an endoscopic procedure may include a first flange and a second flange connected to the first flange by a saddle region having a lumen. The second flange may be proximal to the first flange. The pyloric occlusion device may further include a closure element. The closure element may be configured to occlude a flow of material through the lumen, including across the pylorus when deployed. The closure element may be a closure of the lumen by rotation of one of the first or second flanges about the saddle region relative to the other of the first or second flange.

Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to medical devices for facilitating the flow of fluids and materials in and/or between adjacent body lumens, for example, a stent which maintains an open flow passage between body lumens. In one example, a stent may comprise an elongate body configured to be expandable between a first constrained configuration and a second unconstrained configuration. In the unconstrained configuration, the body may have a first retention member, a second retention member, and a cylindrical saddle region defining a lumen extending along a longitudinal axis therebetween. The first retention member or the second retention member, or both, may comprise a double-walled flange with an axially inward wall and axially outward wall, a portion of the inward wall bending towards a vertical center plane of the saddle region along the longitudinal axis.

Abstract: An implantable device configured to be deployed at a deployment site such as across a body passage. The implantable device has features enhancing the resistance of at least a portion of the implantable device to migration from the deployment site. The implantable device may have surfaces contacting tissue at the deployment site which are configured to promote tissue ingrowth with respect to the implantable device. Surfaces of the implantable device not contacting tissue may be enlarged and coated with a coating material increasing the strength of the coated portions of the implantable device to resist migration of the implantable device with respect to the deployment site.

Abstract: This disclosure relates generally to medical devices, systems, and methods for locating devices and/or anatomy during medical procedures. More particularly, in some embodiments, the disclosure relates to medical device and/or anatomy locating devices, access devices, and systems and methods thereof, for use during, e.g., gastrojejunostomy procedures. In an aspect, a medical device locator may include an elongate member (such as sheath or guidewire) having a proximal end, a distal end, a longitudinal axis, and a length extending along the longitudinal axis. A location device may be disposed along the length of the elongate member.
