Abstract
Medical device for transcatheter heart valve repair comprising a grasping tweezer (1) and a plicating tweezer (2), said grasping tweezer (1) being adapted to grasp a leaflet rim (3) and said plicating tweezer (2) comprising two rotatable flaps (4,5) and a central shaft (6) around which said flaps (4,5) may rotate in a “butterfly manner”, in such a way that the plicating tweezer (2) may adopt a closed or an open configuration. The invention also relates to a method for using this medical device.
Claims14
A medical device for transcatheter heart valve repair comprising:
- a grasping tweezer configured to grasp a leaflet rim to form a prolapsed portion;
- and a plicating tweezer including two rotatable flaps and a central shaft defining a longitudinal axis of the plicating tweezer, wherein each flap has a substantially triangular shape, wherein a first side of a triangle that forms the triangular shape is defined by the central shaft, a second side is located on a proximal end of the plicating tweezer, and a third side is located on a distal end of the plicating tweezer, wherein the second and third sides define a free end for each flap, the free ends of the rotatable flaps configured to approach each other upon turning the rotatable flaps around the central shaft towards each other, and the free ends configured to distance themselves from each other upon turning the rotatable flaps around the central shaft away from each other.
A method for using a medical device for transcatheter heart valve repair, the medical device including a grasping tweezer configured to grasp a leaflet rim of a leaflet, and a plicating tweezer including two rotatable flaps having free ends and a central shaft around which the free ends of the two rotatable flaps are configured to rotate in a butterfly manner such that the plicating tweezer can adopt a closed configuration or an open configuration,
- the method comprising the steps of:
- grasping and pulling the leaflet rim by the grasping tweezer to form a prolapsed portion;
- and
- triangular plicating the prolapsed portion of the leaflet with the free ends of the two rotatable flaps of the plicating tweezer to form a plicated region.
