Abstract: Support frames and medical devices are described. An example medical device comprises an expandable support frame with first and second leaflets attached to the support frame. Each of the first and second leaflets defines a domed radius that is equal to or less than the radius of the expandable support frame when the expandable support frame is in an expanded configuration and the leaflets are subjected to fluid pressure sufficient to affect closure of the valve orifice.

Abstract: A method of treatment for a body vessel is provided. The body vessel includes a dissection flap formed from a wall of the body vessel, which longitudinally separates a natural body vessel lumen into a true lumen and a false lumen. One or more cuts are formed in the dissection flap with a cutting device or system. An expandable device is inserted within the true lumen, and expanded to reappose the dissection flap against the wall of the body vessel where the dissection flap was detached from the wall such that the false lumen is closed. A variety of cut patterns are disclosed.

Abstract: Tissue cutting systems and methods of tissue cutting are provided. In one example, the tissue cutting system includes a first device and a second device adapted for coupling to a power supply. The first device includes a conductive probe. The second device includes a conductive material, for example, as part of an expandable structure, having an outer surface area of conductive material that may be larger than a surface area of the conductive probe. The conductive probe and the conductive material are deployed along opposite sides of a body tissue, such as an aortic dissection flap. Selective electrical power is applied to the conductive probe and the conductive material to cut the body tissue.

Abstract: Animal models useful in the evaluation of medical devices, such as intraluminal medical devices, including intraluminal valve prostheses, are described. An example animal model comprises an animal in which a chordae tendineae attached to at least one of the leaflets of the tricuspid valve has been cut during an interventional procedure. Methods of evaluating intraluminal medical devices are also described. An example methods comprises cutting chordae tendineae attached to a leaflet of a tricuspid valve of an animal; allowing the animal to recover from the step of cutting the chordae tendineae; implanting an intraluminal medical device at a target site within a body vessel of the animal; allowing the animal to recover from the step of implanting an intraluminal medical device; and monitoring in vivo performance of the intraluminal medical device.

Abstract: A method and system for treatment for a body vessel having a dissection flap formed from a wall of the body vessel, which longitudinally separates a natural body vessel lumen into a true lumen and a false lumen. One or more cuts are formed in the dissection flap with the cutting device or system including cutting blades. An expandable device is inserted within the true lumen, and expanded to reappose the dissection flap against the wall of the body vessel where the dissection flap was detached from the wall such that the false lumen is closed. A variety of cut patterns are disclosed.
