Abstract: A device (100) for the excision of a heart valve via a percutaneous route having a proximal (20) and distal (30) end, comprising an expandable cutting instrument, ECI, that forms a receptacle in the open configuration for receiving, compacting and containing the excised heart valve, an expandable cutting block, ECB, and a displacement mechanism (5, 6) for adjusting the distance between the ECI and the ECB (70).

Abstract: A device (100) is presented for excision of a heart valve comprising a first (120) and second (140) clamping element in mutual sliding relation, each having an annular clamping surface (122, 142) which annular clamping surfaces (122, 142) mutually co-operate to form an annular clamping region (166) configured for clamping a heart valve annularly, and a slidable cutting element (160) slidable and rotatable with respect to the annular clamping region (166) configured to circularly excise the heart valve, wherein the slidable cutting element (160) is displaceable within an annulus of the annular clamping zone region (166).

Abstract: The present invention concerns hybrid manual-robotic system for supporting and moving a surgical instrument having active main structure (100) that comprises: a) a base (2) for attachment to an operating table having an operating surface (150); b) a hexahedral-shape frame (3), which shape is formed from a first (5, 5?) and second (4, 4?) pair of opposing parallelograms and opposing proximal (6?) and distal (6) rectangles, which frame (3) is formed by at least seven links (7, 8, 9, 10, 11, 12, 13, 22, 23) connected by revolute joints (14, 15, 16, 17, 18, 19, 20, 26, 27, 109), whereby a) a pair of parallel base links (7, 13) of the proximal rectangle (6?) is coupled to the base (2) by two revolute joints (116, 117), and are configured to lie and remain essentially perpendicular to the plane of the 10 operating surface (150) and to revolve around their longitudinal axes that coincide with the axes of revolution of joints (116, 117), whereby b) said revolute joints are configured to allow the hexahedral frame (3)
