Abrégé

A catheter apparatus and a method for using the catheter apparatus to implant a prosthetic aortic valve into a patient. The catheter apparatus includes a handle assembly and a catheter assembly. The catheter assembly has an outer sheath which defines a sheath cavity within which a pusher is positioned, an outer shaft coupled to a slider of the handle assembly and to the sheath cavity, and an inner shaft to which the pusher is attached. A self-expanding prosthetic valve is positioned in the outer sheath and coupled to the pusher. Actuation of the handle causes the slider and the outer sheath to move in a proximal axial direction to expose and deploy the self-expanding prosthetic valve. The self-expanding prosthetic valve may have tabs that are engaged with indents of the pusher such that the tabs are released sequentially during deployment.

A prosthetic valve device and a method of forming a frame thereof. The method may include cutting a pattern into a tube having a first inner diameter and an axis, the pattern having a plurality of post pattern sections arranged on the tube in a circumferentially spaced-apart manner and a plurality of lattice pattern sections extending between the post pattern sections. The method may further include diametrically expanding the tube until the tube has a second inner diameter that is greater than the first inner diameter. The expanded tube may have a plurality of axial posts arranged on the expanded tube in a circumferentially spaced-apart manner and a plurality of lattices having open cells extending between the axial posts.

Abrégé

A catheter and a method for using the catheter to implant a replacement aortic valve into a patient. The catheter includes an expandable wall, an outer sheath, a first tube operably coupled to the expandable wall, and a second tube operably coupled to the expandable wall. The catheter also includes a pusher that is fixed to the second tube, the pusher being spaced apart from the expandable wall by a distance that is sufficient to accommodate the replacement aortic valve. The outer sheath is movable relative to the expandable wall so that in one state the expandable wall is disposed within the outer sheath and in another state the expandable wall is located outside of the outer sheath. The expandable wall is configured to radially expand. The catheter also includes a handle assembly that is adjusted by a surgeon to achieve the functions of the catheter.
