Abstract: Devices and methods for occluding or promoting fluid flow through openings are disclosed. In one exemplary embodiment an occlusion device is provided having an expandable outer elongate tubular body, a guide member extending from a distal end of the outer body, and a slide tube disposed within the outer body, the proximal portions of the outer body and the slide tube being fixedly mated. The slide tube is configured to slide distally within the outer tubular body when the tubular body is expanded to form wings. A tether can be included as part of the device and it can be used to assist in positioning and locking a location of the device in an opening. Exemplary methods for delivering devices disclosed herein are also provided.

Abstract: Surgical assemblies and related methods are provided for using an actuator to deploy an coupler configured to close a tissue puncture or natural opening in the body. The surgical assembly includes an actuator assembly having an elongate shaft including an outer shaft and an inner shaft concentrically disposed within the outer shaft to define a fluid flow path therebetween, and a deployable coupler coupled to a distal end of the outer shaft. The deployable coupler has a plurality of proximal and distal slits formed therein and configured to form proximal and distal wings. The proximal and distal slits are configured to allow blood to flow therethrough into an inner lumen of the deployable coupler and through the fluid flow path to a fluid outlet port formed in the actuator assembly.

Abstract: Surgical assemblies and related methods are provided for using an actuator to deploy an coupler configured to close a tissue puncture or natural opening in the body, or to create an anastomosis. The surgical method includes deploying first and second anastomotic couplers within a patient to create anastomoses in the body to aid in the treatment of various ailments. The first coupler is deployed to fluidly join a gall bladder and an ileum, and the second coupler is deployed to fluidly join a proximal ileal loop and a distal ileal loop. Fluid can flow between central lumens of the first and second couplers.
