    摘要： A medical apparatus (100) is provided, comprising a closure device (102), which comprises a locking member (130) and a tubular member (121) having two sets of struts (122, 123) being provided with a hinge section, and an insertion assembly (101), which comprises a holder (106) and an actuator (107), the holder being releasably engaged in the locking member and the actuator being releasably engaged with the tubular member. The insertion assembly further comprises a spring (105) which effectuates a relative movement between the holder and the actuator, which causes the closure device to move from a first elongated introduction configuration via a second positioning configuration to the third closed configuration, during which the tubular member is compressed such that the hinge sections have moved radially away from a longitudinal central axis of the closure device. The compression of the device can be reversed if needed, yet the device can not be compressed further without providing force in excess of the spring force, whereby the final irreversibly locked state is achieved.

    摘要： Apparatus for permanent placement across an ostium of a left atrial appendage in a patient, which includes a filtering membrane configured to extend across the ostium of the left atrial appendage. The filtering membrane has a permeable structure which allows blood to flow through but substantially inhibits thrombus from passing therethrough. The apparatus also includes a support structure attached to the filtering membrane which retains the filtering membrane in position across the ostium of the left atrial appendage by permanently engaging a portion of the interior wall of the left atrial appendage. The support structure may be radially expandable from a first configuration to a second configuration which engages the ostium or the interior wall of the left atrial appendage. The filtering membrane may define an opening therethrough that is configured to expand from a first size which inhibits the passage of thrombus therethrough to a second size which allows an interventional device, e.g., an expansion balloon, to pass therethrough, and wherein the opening is resiliently biased towards the first size.

    摘要： The present invention relates to the field of medicine, more precisely to the field of micro-surgery, and may be used to expand narrowed sections of tubular organs or vessels. This invention may also be used for attaching edges on openings in tissues as well as for attaching prostheses such as obstruction, valve or filtration prostheses on wall defects and on the anastomoses of hollow or tubular organs. This invention may be used to increase the scope of applications and the functional capacities of this micro-surgery fixation device as well as to enhance reliability and safety when installing the same. In one embodiment, the micro-surgery device comprises two or more springs, each spring being in the shape of a truncated cone or flat ring made of a zigzag-shaped rod defining a closed loop. The mobile springs are connected with each other at the zigzag summits located on the circumference. The springs may be biased under the action of an external load and recover their initial position. In another embodiment, the micro-surgery device comprises a single spring which is in the shape of a truncated cone or flat ring made of a zigzag-shaped rod forming a closed loop. The zigzag summits are located on the circumference and connected to mobile fixations which are each in the form of a resilient rod fitted with a hook. The manipulation push-bar includes rods with guides connected to a catheter tube via a coupling. The rods are mounted inside the catheter tube and the coupling are capable of longitudinal displacement within the latter and along the guides.
