Abstract: The present technology is directed to implantable medical devices, systems, and methods for restricting, closing, or blocking an opening or defect in an anatomical structure. For example, many embodiments of the present technology are directed to implantable closure devices for plugging or sealing an opening in an anatomical structure separating a first body region and the second body region. In many of the embodiments described herein, the implantable closure devices are designed to be “recrossable,” such that a catheter or other percutaneous tool can be passed through the closure device after the device has been implanted.

Abstract: A stent-graft prosthesis includes a graft material having a tubular construction, a frame coupled to the graft material, and a port or opening disposed between a proximal end and a distal end of the graft material. The port or opening is open during deployment of the stent-graft prosthesis to enable blood flow from a graft lumen within the graft material to exit the graft lumen, and the port or opening is blocked upon full deployment of the stent-graft prosthesis to prevent blood flow from within the graft lumen from exiting the graft lumen through the port or opening.

Abstract: The present technology is generally directed to medical systems having sensors and diaphragms. The sensor device can include a body having a diaphragm. The diaphragm can be formed, for example, by applying a force to the body to create an impression or pattern that corresponds to the diaphragm. The sensor device can be positioned at least partially within a body cavity, and the diaphragm can be configured to flex or bend in response to one or more physiological parameters in the body cavity. In some embodiments, the sensor device can include one or more sensor measurement components configured to measure the one or more physiological parameters based on the flexing or bending of the diaphragm.

Abstract: The techniques of this disclosure generally relate to a method including navigating an adhesive catheter to a proximal end of a false lumen of a dissection. The false lumen is defined by a septum and a vessel wall. The method further includes delivering an adhesive from the adhesive catheter to the proximal end of the false lumen. The adhesive is compressed between the septum and the vessel wall to close the false lumen.

Abstract: Stent graft devices are disclosed that include a trifurcation of a main body into three branch lumens. The devices may be used to treat thoracoabdominal aortic aneurysms. The three branch lumens may split at a common point or plane in the device. One or more of the branch lumens may further split, such as bifurcate, in order to perfuse branch vessels of the aorta.
