Abstract: Implantable devices—such as stents and rings—that comprise markers for tracking their deployment in a body lumen are disclosed. The markers may be used to monitor progress of expansion of the implantable device, potential migration of the implantable device, and diameters of the body lumen. Markers may be deployed in the body lumen separately from another implantable device to assist tracking of migration of the implantable device. Markers may be placed circumferentially around a wall of a body lumen to track growth of an aneurysm or a stricture.

Abstract: Devices used to drain fluid are disclosed. The devices may be configured to drain fluid from a body cavity using a vacuum pressure.

The devices can be configured to be shipped in a collapsed state.

Abstract: Stent devices deployable at a treatment site within a lumen of a patient's body are disclosed. The stent devices include a plurality of discrete stent rings coupled to a coupling member. The discrete stent ring includes a plurality of expandable structures. The expandable structure includes a longitudinal strut and a plurality of strut arms extendable from the longitudinal strut. The coupling member is a polymeric tube or a plurality of elongate filaments. The longitudinal struts are coupled to the coupling member.

Abstract: Medical devices for delivering compositions or medical articles to a patient are disclosed. The medical plug delivery devices can include a fluid delivery device (e.g., a syringe), a frame, and a rotatable magazine. The rotatable magazine can include a plurality of chambers that each hold a composition or a medical article (e.g., a medical plug). By rotating the rotatable magazine relative to the frame, material within the chambers of the rotatable magazine can be sequentially deployed to a patient.

Abstract: Bifurcated endovascular prostheses used to treat diseased blood vessels, such as arteries, are disclosed. In some embodiments, the bifurcated endovascular prosthesis is configured to be implanted within the diseased blood vessels adjacent a diseased section. The bifurcated endovascular prosthesis includes a primary stent graft and a secondary stent graft. The primary stent graft includes a pocket or sleeve disposed within a bore. A proximal portion of the secondary stent graft is disposed within the pocket or sleeve. Blood flow through the bifurcated endovascular prosthesis is divided into two flows, a first flow through the primary stent graft and a second flow through the secondary stent graft.

Abstract: Devices used to restrict flow within a blood vessel are disclosed. Devices within the scope of this disclosure include a braided lattice of nitinol wires that form self-expanding enclosures of an embolic structure. The devices may further include embolic particles disposed within the enclosures. Methods of deploying the devices with the embolic particles are disclosed. Methods of manufacturing the devices with the embolic particles disposed within the enclosures are disclosed.

Abstract: A medical appliance or prosthesis comprising a support structure and a covering is disclosed. The support structure includes a frame comprising a wire winding. The wire winding includes an end row including apexes and troughs. The apexes and troughs are configured to allow crimping of the frame to a low profile while reducing strain on the wire. The covering includes a multilayer construct including fibrous inner and outer layers and a barrier layer.

Abstract: A vascular prosthesis deployment device and related methods are disclosed. In some embodiments the deployment device may include a delivery catheter assembly.
