    摘要: A method of valve implantation includes installing a leaflet lasso on a host leaflet assembly at an implantation site within a patient's body. The method includes positioning an expandable prosthetic heart valve in a crimped state within a central region of the host leaflet assembly. The method includes radially expanding the prosthetic heart valve to a working diameter. During at least a portion of radially expanding the prosthetic heart valve, the prosthetic heart valve contacts a central lasso portion of the leaflet lasso and applies a radial force to the central lasso portion that results in folding of at least one leaflet of the leaflet assembly.

    摘要: Endovascular graft devices and systems are discussed and described. 1. An endovascular graft device includes a tubular membrane body having a proximal end and a distal end, a midsection extending from the proximal end to the distal end, and at least one flexible region positioned in the midsection, where the at least one flexible region includes a flexible covering configured to expand to a systolic expansion limit and contract to a diastolic contraction limit under aortic pressure. The endovascular graft device additionally includes an internal scaffold extending through at least a portion of the membrane body between the proximal end and the distal end, the internal scaffold, the proximal end, and the distal end being radially expandable to a deployment expansion limit.

    摘要: An aortic graft assembly includes a tubular component that defines a wall aperture having a proximal end that extends perpendicular to a major longitudinal axis of the tubular aortic component, and a tunnel graft connected to the wall of the tubular aortic component and extending from the wall aperture toward a proximal end of the tubular aortic component. A filter that captures emboli consequent to implantation of the aortic graft assembly spans at least on of an aperture in the wall of the tubular aortic component and the tunnel graft. The method for delivery of the aortic graft assembly includes delivering the aortic graft assembly through the wall aperture and into interfering relation with the tunnel graft, thereby rupturing the filter, while the filter continues to retain captured emboli.

    摘要: 본 발명은 압전진동구조물이 설치된 인공혈관에 관한 것이다. 본 발명에 따른 인공혈관은 고분자 튜브의 일 또는 양 말단에 압전진동구조물이 설치되고, 상기 압전진동구조물에서 전기적 신호에 따라 진동이 발생함으로써 혈관과 접합된 문합 부위에서 혈전이 생성되는 것을 방지하거나 내막의 과증식을 방해할 수 있으므로 혈관 개통율을 향상시키고 협착증을 방지할 수 있다.

    摘要: A device is disclosed for occluding an anatomical passage between first and second anatomical structures. The device includes a tip portion having a proximal element connected to a distal element through a member. The proximal element and/or distal element is movable axially along the tip portion while the other element preferably remains fixed in place. A handle is coupled to a proximal end of the tip portion through a shaft. The tip portion is positioned across the anatomical passage so that the proximal element occludes a first side of the passage and the distal element occludes a second side of the passage. A locking structure, such as a nut, is positioned or crimped against the proximal element, and, once done, the tip portion is released at the occluded passage.
