摘要： Disclosed is an expandable percutaneous sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion to a second, enlarged cross-sectional configuration. The sheath is maintained in the first, low cross-sectional configuration by a tubular restraint. In one application, the sheath is utilized to provide access for a diagnostic or therapeutic procedure such as percutaneous nephrostomy or urinary bladder access.

摘要： The present invention relates generally to systems and methods for aligning and implanting orthopedic fixation or stabilization implants within the body. In one embodiment, the system includes at least two bone anchors, at least one of which is provided with a transverse portal and a locking member. In one aspect, the system also includes at least one linkage rod, for linking two or more bone anchors through their respective locking members. The linking rod may include at least one angularly adjustable joint, which may be fixed by actuating the locking member. The bone anchors and the linkage rod may be locked into place to form a spinal fusion or fixation prosthesis.

摘要： Disclosed is a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The prosthesis comprises a self-expandable wire support structure having a tubular main body support and first and second branch supports. The prosthesis can have a plurality of radially outwardly extending barbs. The branch supports may articulate with the main body to permit the branches to pivot laterally from the axis of the main body throughout a substantial range of motion.

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： An inflatable corpectomy device comprises a balloon, which defines a cavity for receiving a hardenable media. The device can be inserted in an un-inflated form into a space formerly occupied by a diseased or damaged vertebrae bone. When inflated with a hardenable material, the device expands and fills the space. Various bone anchors or plates can be used in combination with the inflatable device to bridge the space and stabilize the spine while the device hardens.

摘要： Disclosed is an expandable fusion cage which facilitates the fusion of adjacent bony surfaces, preferably those in the spine. In a preferred embodiment, the fusion cage. The surfaces of the cage which are intended to contact the vertebral endplates have multiple portions cut out of the metal to form sharp barbs. As the cage is expanded to come into apposition with endplates above and below, the sharp barbs protrude into the subcortical bone of the vertebral body thus securing the cage in place. Multiple holes or fenestrations are present on the superior and inferior surfaces of the cage to permit contact of morselized autologous bone and/or an artificial bone matrix material with the prepared endplate surface.

摘要： Apparatus, systems, and methods are provided for repairing heart valves through percutaneous transcatheter delivery and fixation of annuloplasty rings to heart valves via a trans-apical approach to accessing the heart. A guiding sheath may be introduced into a ventricle of the heart through an access site at an apex of the heart. A distal end of the guiding sheath can be positioned retrograde through the target valve. An annuloplasty ring arranged in a compressed delivery geometry is advanced through the guiding sheath and into a distal portion of the guiding sheath positioned within the atrium of the heart. The distal end of the guiding sheath is retracted, thereby exposing the annuloplasty ring. The annuloplasty ring may be expanded from the delivery geometry to an operable geometry. Anchors on the annuloplasty ring may be deployed to press into and engage tissue of the annulus of the target valve.
