An implantable closure structure is delivered using minimally invasive techniques, and inhibits the migration of liquid and particulate matter from inside a physiological cavity or opening, such as an aneurysm or a septal defect, as well as inhibiting the flow of liquid and particulate matter, such as from an associated blood vessel or chamber, into the physiological cavity or opening. The device has a closure structure that covers the neck or opening of a cavity and has one or more anchoring structures for supporting and retaining the closure structure in place across the cavity or opening.

Methods and systems for endovascularly clipping and repairing lumen and tissue defects

Systems for delivering a bifurcated stent to a bifurcation site include catheters and/or bifurcated systems delivered therefrom. A catheter includes a balloon with a bulge region that allows a portion of the stent to be expanded.

Bifurcated stent and delivery system

Systems for delivering a bifurcated stent to a bifurcation site comprise catheters and/or bifurcated stents delivered therefrom.

A bifurcated stent includes a first stent section and a second stent section. The first stent section is balloon expandable, has an unexpanded configuration, an expanded configuration, and a tubular wall defining a secondary opening. The secondary stent section is self-expanding and an end of the secondary stent section is engaged to a portion of the tubular wall of the primary stent section defining the secondary opening. The secondary stent section has an unexpanded configuration with a first length and an expanded configuration with a second length where the first length is less than the second length. The secondary stent section is expanded to the expanded configuration after the primary stent section is expanded to the expanded configuration. The secondary stent section forms a portion of the tubular wall of the primary stent section in the unexpanded configuration.

A bifurcated stent comprises a first stent section and a second stent section. Each stent section is expandable from a predeployed state to a deployed state independently from one another. The second stent section having an end engaged to a receiving region of the first stent section. In the deployed state the first stent section defines a primary flow path and the second stent section defines a secondary flow path in fluid communication with the first flow path. At least a portion of one or both the first stent section and second stent section is constructed from a wire member.

Bifurcated stent

The present invention comprises a guidewire having a compressible guide section capable of deflecting a catheter to abut a lumen wall. The compressible guide section exerts an outward radial force while it is at least partially compressed within a lumen. The guide section permits a physician to precisely locate a catheter within a body lumen and adjust a catheter tip orientation to be directed to a particular side of a body lumen. A method is disclosed for properly matching a guidewire and a catheter to operate together in the present invention, along with a force measuring instrument to assist in measuring a catheter's resistance force value. This method and systems of the present invention involve determining the exact force relationship between the compressible guide section and the resistance of the catheter in vitro.
