摘要： Systems, methods and devices are provided for treating heart failure patients suffering from various levels of heart dilation. Such heart dilation is treated by reshaping the heart anatomy with the use of shape memory elements. Such reshaping changes the geometry of portions of the heart, particularly the right or left ventricles, to increase contractibility of the ventricles thereby increasing the stroke volume which in turn increases the cardiac output of the heart. The shape memory elements have an original shape and at least one memory shape. The elements are implanted within the heart tissue or attached externally and/or internally to a surface of the heart when in the original shape. The elements are then activated to transition from the original shape to one of the at least one memory shapes. Transitioning of the elements cause the associated heart tissue areas to readjust position, such as to decrease the width of the ventricles. Such repositioning is maintained over time by the elements, allowing the damaging effects of heart dilation to slow in progression or reverse.

摘要： Methods of implanting an annuloplasty ring to correct maladies of the mitral annulus that not only reshapes the annulus but also reconfigures the adjacent left ventricular muscle wall. The ring may be continuous and is made of a relatively rigid material, such as Stellite. The ring has a generally oval shape that is three-dimensional at least on the posterior side. A posterior portion of the ring rises or bows upward from adjacent sides to pull the posterior aspect of the native annulus farther up than its original, healthy shape. In doing so, the ring also pulls the ventricular wall upward which helps mitigate some of the effects of congestive heart failure. Further, one or both of the posterior and anterior portions of the ring may also bow inward. The methods include securing the annuloplasty ring with the anterior portion against the annulus anterior aspect and the posterior portion against the annulus posterior aspect so that the ring posterior portion elevates, and may also pull radially inward, the annulus posterior aspect and corrects the mitral regurgitation.

摘要： Methods and devices are provided for support of a body structure. The devices can be adjusted within the body of a patient in a minimally invasive or non-invasive manner such as by applying energy percutaneously or external to the patient's body. The energy may include, for example, acoustic energy, radio frequency energy, light energy and magnetic energy. Thus, as the body structure changes size and/or shape, the size and/or shape of the annuloplasty rings can be adjusted to provide continued reinforcement. In certain embodiments, the devices include an anterior portion, a posterior portion and two lateral portions corresponding to intersections of the anterior portion and the posterior portion. The devices have, a first shape in a first configuration and a second shape in a second configuration and are configured to transform from the first configuration to the second configuration in response to an activation energy applied thereto. The transformation is configured to reduce a distance between the anterior portion and the posterior portion without substantially decreasing a distance between the two lateral portions.

摘要： An endoluminal grafts is provided which is constructed to be radially collapsed and/or radially compressed to a small diameter. The graft has wireforms which generally comprise a wire deformed into generally annular configuration and consisting of a plurality of curvilinear wave forms. The wave forms have a plurality of first apices in linear alignment with each other, a plurality of second apices in linear alignment with each other, and a plurality of curvilinear segments traversing back and forth between said first and second apices. The graft is i) initially disposable in a radially compact configuration of a first diameter and ii) subsequently expandable to a radially expanded configuration of a second diameter, said second diameter being larger than said first diameter. When in its radially compact configuration, the adjacent curvilinear segments of the wireforms will nest or seat in abutting contact with one another, thereby minimizing the diameter of the graft while in its radially compact configuration.

摘要： An aortic valve sizing obturator apparatus for employment in determining the correct size of an aortic annulus. The apparatus includes a cylindrical obturator body with a flange member formed thereabout. At least the under surface of the flange member is of a non-planar, multi-curvate configuration to thereby be complimentary in shape to the annulus of an aortic valve when seated in the annulus during size determination. Within the cylindrical obturator body can be disposed a handle connector to which a handle can be attached during placement of the obturator apparatus within an annulus. The present invention also includes methodology for determining the size of an aortic valve annulus by employing a plurality of differently-sized aortic valve sizing obturators defined above and individually seating them sequentially within the aortic annulus until an obturator that reflects annulus size is located.

摘要： In general, the present invention comprises an holding apparatus for facilitating implantation of a prosthetic heart valve within a mammalian heart. The holding apparatus generally comprises a cage or enclosure having a heart valve prosthesis retention space defined therewith. The proximal end of the holding apparatus is releasably attached to the proximal end of the heart valve prosthesis such that, when the holding apparatus is advanced in a forward direction, a "pulling" force will be exerted upon the proximal end of the prosthesis, rather than a "pushing" force being exerted upon the distal end of the prosthesis. The releasable attachment of the prosthesis to the holding apparatus may be accomplished by any suitable attachment member, and preferably comprises a number of suture threads which are passed through the prosthesis and threaded upon the holding apparatus at location(s) which are easily accessible such that the surgeon may cut the suture threads to effect release of the heart valve prosthesis, during the prosthesis implantation procedure. Also described and claimed are associated methods for utilizing the above-described holding apparatus to effect implantation of a prosthetic heart valve.

摘要： A processing vessel for isolating microvessel endothelial cells from liposuctioned fat tissues includes a fat-receiving basket defined by polyester screen material. Fat tissue removed from a patient by liposuction is received into the basket and is rinsed and digested with an enzymatic solution. The freed microvessel endothelial cells from the fat tissues are separated from the fat cells, and from blood cells and other materials which may be present in the basket by centrifuging. A bottom chamber of the processing vessel is configured to define a "pellet" of isolated endothelial cells which may be removed from the processing vessel for deposition on the inner lumenal surface of a synthetic graft which the fat-donor patient is to receive.
