摘要： Valve prostheses are disclosed that are adapted for secure and aligned placement relative to a heart annulus. The valve prostheses may be placed in a non-invasive manner, e.g., via transcatheter techniques. The valve prosthesis may include a resilient ring, a plurality of leaflet membranes mounted with respect to the resilient ring, and a plurality of positioning elements movably mounted with respect to the flexible ring. Each of the positioning elements defines respective proximal, intermediate, and distal tissue engaging regions cooperatively configured and dimensioned to simultaneously engage separate corresponding areas of the tissue of an anatomical structure, including respective first, second, and third elongate tissue-piercing elements. The proximal, distal, and intermediate tissue-engaging regions are cooperatively configured and dimensioned to simultaneously engage separate corresponding areas of the tissue of an anatomical structure so as to stabilize a position of the valve prosthesis with respect to the anatomical structure, including wherein for purposes of so simultaneously engaging the separate corresponding areas of tissue, at least one of the first, second, and third elongate tissue-piercing elements is pointed at least partially opposite the direction of blood flow, and at least another thereof is pointed at least partially along the direction of blood flow. The valve prosthesis may also include a skirt mounted with respect to the resilient ring for sealing a periphery of the valve prosthesis against a reverse flow of blood around the valve prosthesis.

摘要： Valve prosthesis systems and methods/systems for placement of such valve prostheses are provided that facilitate efficient, reliable and minimally invasive delivery modalities. The placement systems and methods permit remote manipulation and positioning of the valve prosthesis such that desirable placement relative to anatomical structures, e.g., the heart annulus, may be achieved. The valve prosthesis includes a resilient ring, a plurality of leaflet membranes mounted with respect to the resilient ring, and a plurality of positioning elements movably mounted with respect to the flexible ring. The delivery system includes a first elongate element that terminates at the valve prosthesis and is manipulable by an operator to remotely rotate the positioning elements relative to the flexible ring. A second elongate element terminates at the valve prosthesis and is manipulable by an operator to remotely advance the valve prosthesis downward into an anatomical annulus. The second elongate element may be manipulated to remotely advance the valve prosthesis into the anatomical annulus to assume a position for supporting post-implantation function of the valve prosthesis in situ. The first elongate element may be further manipulated to remotely rotate the positioning element relative to the flexible ring to cause the positioning element to engage tissue associated with the anatomical annulus and to thereby maintain the post-implantation position of the valve prosthesis in situ. Methods for valve prosthesis deployment are also provided.

摘要： A shaped diaphragm as a part of a fluid processing disposable set acting as a centrifuge system rotor. The fluid processing disposable set has a variable-volume chamber and a fluid port. The shaped diaphragm defines a wall of the variable-volume chamber. The chamber is in fluid communication with the fluid port and is defined by a fixed wall and an elastic wall. The elastic wall is formed by the shaped diaphragm. The disposable set may also have a rotary seal coupled to the fluid port and fluidly coupled to the variable-volume chamber. The shaped diaphragm may be convoluted. The convolution may be a single fold and may have a plurality of folds located symmetrically about an axis. The shaped diaphragm may, alternatively, be essentially planar in an unstretched position while varying in thickness along a diaphragm dimension. Centrifuge rotors, systems, and methods for selective harvest of fluid constituents from a whole fluid are detailed.
