A system and a method for treating an aortic dissection comprising deploying a crescent-shaped stent graft in the false lumen through the re-entry point. The stent graft comprises a graft structure secured to a stent structure. The stent graft is geometrically configured to block or occlude the blood flow through to the false lumen.

A multi-stage stent including a stent body and a bio-erodible material is provided. The stent body can be compressed in an initial state and the bio-erodible material can be coupled to the stent body in a configuration that holds the stent body in an expanded first state, following a first stage expansion from the initial state upon deployment of the stent body. Upon erosion of the bio-erodible material the stent body is released from the first state to expand further in a second stage expansion to a second state.

A method of deploying a modular multibranch stent assembly. The method includes deploying a first modular stent device in an ascending aorta. The first modular stent device includes a main body, a bypass gate extending from the main body, and a bifurcated contra limb extending from the main body. The bifurcated contra limb includes a first distal limb and a second distal limb. The method further includes deploying a first bridging stent graft in the first distal limb and/or a second bridging stent graft in the second distal limb.

Lumen support devices and methods of their use are provided. A lumen support includes one or more plastically deformable cells having two stable configurations with no stable configurations between the two stable configurations. The lumen support device may be plastically deformed to other stable configurations.

A debranching Great vessel stent graft and methods for its use, where the stent graft comprises, a main body stent graft with a first bifurcation defining a first leg and a second leg, the main body stent graft has distal and proximal ends, the main body stent graft has a diameter at the proximal end in the range from about 18 mm to about 28 mm, the first leg and the second leg each have a diameter in the range from about 12 mm to about 18 mm, the distance from the proximal end of the main body to the distal end of the first leg is in the range from about 30 mm to about 50 mm, and the distance from the proximal end of the main body to the distal end of the second leg is in a range from about 50 mm to about 70 mm.

A prosthetic valve is advanced to a heart of a subject while the prosthetic valve is in a compressed state thereof, the prosthetic valve including a plurality of snares coupled to a tubular valve body. The prosthetic valve is positioned within the heart such that the plurality of snares is disposed upstream of the leaflets, and the plurality of snares is expanded upstream of the leaflets. Subsequently the prosthetic valve is moved in a downstream direction such that the plurality of snares is disposed downstream of the leaflets. Subsequently, the prosthetic valve is secured at the native valve while the plurality of snares remains disposed downstream of the leaflets.

The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region is generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.

A stent graft delivery device includes a handle body, a distal handle, a proximal handle, a guidewire lumen, a nose cone, a rigid outer catheter, a graft push lumen, a sheath lumen, an inner sheath and a locking ring. The locking ring is switchable between an advancement position and a delivery position. The stent graft delivery device is employed in methods for endovascular delivery of stent grafts.

A system for treating a bifurcated vessel that includes a first delivery catheter and a second delivery catheter. The first delivery catheter carries a proximal first stent and a distal second stent. The first delivery catheter also has a first elongate shaft, a proximal first expandable member with the proximal first stent disposed thereover, and a distal second expandable member with the distal second stent disposed thereover. The proximal first expandable member and distal second expandable member are independently expandable of one another. The second delivery catheter carries a third stent. The second delivery catheter also has a second elongate shaft, and a third expandable member with the third stent disposed thereover. The third expandable member is independently expandable of the proximal first expandable member and the distal second expandable member.

A deployment apparatus and method for deploying one or more stents to a bifurcated vessel is provided. The invention is particularly suited for T-type bifurcated vessels where a side branch extends from a main branch. The deployment apparatus has a primary inflatable portion for engagement within the main branch and a secondary inflatable portion for engagement within the side branch. A main stent is arranged on the primary inflatable portion and radially expanded within the main branch while the secondary inflatable portion maintains registration with the side branch. A side branch stent is then arranged on the secondary inflatable portion and expanded within the side branch while the primary inflatable portion maintains registration with the expanded main stent. A bifurcated stent system suitable for bifurcated lesions is also provided comprising a side branch stent with a shaped end designed to engage a similarly shaped side opening in a main stent.
