    摘要: A system configured to cut leaflet tissue at a cardiac valve may comprise a guide catheter and a cutting mechanism routable through the guide catheter. The cutting mechanism includes a cutting arm and a plurality of grasping arms rotatably coupled to the cutting arm. The grasping arms are connected to the cutting arm via a central hinge and are actuatable between a closed position against the cutting arm and an open position where the grasping arms extend laterally away from the cutting arm by rotating about the hinge. Targeted cardiac leaflet tissue may be grasped between the cutting arm and the grasping arms and cut by a cutting element that is attached to or extends through the cutting arm.

    摘要: An endoscope hybrid knife includes: a handle part having a hollow portion and an opening; first and second handle sliders coupled to the outer peripheral surface of the handle part so as to be slidable forwards and backwards in the longitudinal direction; a pipe disposed in the hollow portion of the handle part, and connected to the first handle slider; a second knife disposed to pass through the pipe, and connected to the second handle slider; a fluid injection part, which is coupled to one end of the handle part for injecting fluid therein; an inner tube which is connected to one end of the fluid injection part; a first knife coupled to the end of the pipe; and an insulating tip coupled to the end of the first knife, wherein the first knife and the second knife are slidable independently of each other.
