Abstract: A heart valve system, the system including a radially self-expandable tubular body and a valve. The tubular body having an inflow end and an outflow end such that the outflow end includes a proximal section and a plurality of beams. The plurality of beams being disposed distally of the proximal section in an outflow direction. Additionally, the tubular body including struts with peaks and valleys at the inflow end of the tubular body such that the proximal section of the outflow end is disposed distally of the peaks and valleys in the outflow direction. Furthermore, the tubular body being configured such that movement of the proximal section of the outflow end radially inward causes the inflow end to flare radially outward, and an arrangement of the struts being configured such that movement of the peaks radially inward causes the valleys to flare radially outward.

Abstract: A prosthetic heart valve can include a valve frame having a wireform portion and a stent portion. The wireform and stent portions can be undetachably coupled together via a plurality of upright struts so as to form a one-piece prosthetic heart valve frame. Alternatively, a self-expanding wireform portion and a balloon-expandable stent portion can be coupled together via one or more leaflets and a subassembly having a flexible leaflet support stent and a sealing ring. The wireform portion can include cusps and commissures configured to support a plurality of leaflets. The prosthetic valve can be radially collapsible for minimally invasive and/or transcatheter delivery techniques. Disclosed embodiments can also provide flexion of the wireform portion (e.g., of the commissures) in response to physiologic pulsatile loading when the valve is implanted in a patient's native valve annulus. Methods of making and using prosthetic heart valves are also disclosed.

Abstract: Systems and methods for treating thrombosis and or emboli in a peripheral vasculature of a patient are disclosed herein. The method can include providing a thrombus extraction device including a proximal self-expanding coring portion formed of a unitary fenestrated structure and a distal expandable tubular portion formed of a braided filament mesh structure; advancing a catheter constraining the thrombus extraction device through a vascular thrombus in a vessel; deploying the thrombus extraction device from the catheter from a constrained configuration to an expanded configuration; retracting the thrombus extraction device proximally so that the coring portion cores and separates a portion of the vascular thrombus from the venous vessel wall while the mesh structure captures the vascular thrombus portion; and withdrawing the thrombus extraction device from the patient to remove the vascular thrombus portion from the vessel.

Abstract: The present invention relates to a method for manufacturing a stent, the method using a jig in which detachable protruding pins are installed at all respective location points at which circumference division lines and length division lines intersect each other, the method forming cells through intersection of wire by setting any one of the location points as a start point and repeatedly bending and moving the wire from the start point upward and downward to pass over the protruding pins located in diagonal directions, wherein a first stent woven such that intersection portions formed through the intersection of a wire are spaced apart from each other in a diagonal direction and arranged one for each length division line and a second stent woven to maintain the structural stability of the first stent and to prevent the first stent from being twisted can be provided as a single stent.

Abstract: Disclosed are self-expanding medical implants for placement within a lumen of a patient. The implants comprise a woven or non-woven structure having a substantially tubular configuration, and are designed to be low-profile such that they are deliverable with a small diameter catheter. The implants have a high recoverability and desired mechanical properties.

Abstract: A braided stent system includes an expansion ring attached to internal and external surfaces of a lumen. A frame of the ring may impart an outwardly expanding radial force to the lumen, the frame including a plurality of elongate members joined at a coupling and at first and second intersections opposite the coupling. A clip can extend from the intersections and can be operable to slidably secure the frame to the inner and outer surfaces of the lumen.
