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
1-12. (canceled)
13:
- A medical device for transcatheter heart valve repair comprising:
- a grasping tweezer configured to grasp a leaflet rim;
- and
- a plicating tweezer including two rotatable flaps and a central shaft around which 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.
1 more element
14:
- The medical device according to claim 13, wherein each flap has a substantially triangular shape.
15:
- The medical device according to claim 14, wherein a first side of a triangle that forms the triangular shape is mainly defined by the central shaft, and 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.
16:
- The medical device according to claim 15, wherein the central shaft and the third side form an angle between 0° and 90°.
17:
- The medical device according to claim 16, wherein the angle is between 15° and 35°
18:
- The medical device according to claim 13, wherein each flap is includes a plurality of segments.
19:
- The medical device according to claim 18, wherein the plurality of segments are covered by a mesh.
20:
- The medical device according to claim 13, wherein at least one flap includes a releasable tissue fixing means.
21:
- The medical device according to claim 13, wherein at least one flap includes a tissue-cutting device.
22:
- The medical device according to claim 13, wherein the central shaft is made rotatable with respect to a main axis of the plicating tweezer.
23:
- The medical device according to claim 20, wherein the releasable tissue fixing means includes staples.
24:
- 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 and a central shaft around which 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 the leaflet rim;
- and
- triangular plicating a region of the leaflet.
1 more element
25:
- The method according to claim 24, further comprising a step of:
- cutting the plicated region of the leaflet;
- and
- removing the plicated region.
