Surgical device for connecting soft tissue
The invention comprises a surgical instrument including an external tube ( 2 ) and two elongated members ( 4 ) positioned in said tube ( 2 ), each of which includes a distal end ( 10 a ) for capturing one of the two tissue zones (M 1 , M 2 ) to be attached. The instrument ( 1 ) may further comprise a catching member ( 22, 25 ) for each tissue (M 1 , M 2 ) to be attached; a rod ( 15, 16 ) linked to each catching member ( 22, 25 ) enabling tension to move axially, said rod ( 15, 16 ) being separable from said catching member ( 22, 25 ) when a tension is exerted on it beyond a certain threshold; and a member ( 17 a ) forming a stop for locking axially each catching member ( 22, 25 ) during said tension.
1. A system for repairing a cardiac valve, said system comprising:
a tube suitable for introduction through a patient's vasculature and into a chamber of a heart;
a clipping system comprising a first element adapted to be brought up beneath a pair of valve leaflets from the ventricular side and a second element adapted to be brought down over the pair of valve leaflets from the atrial side, wherein the first element engages the ventricular side of both leaflets and the second element engages the atrial side of both the leaflets to capture both leaflets therebetween and wherein the first and second elements may be left to attach the free edges of the leaflets together; and
a pair of elongate elements each having a distal extremity for grasping or releasing a valve leaflet, the pair of elongate elements in fluid communication with a vacuum source and extensible from a distal end of the tube, wherein the valve leaflets are grasped when vacuum is applied to the elongate elements.
2. The system of claim 1 , wherein the tube further comprises a lumen therethrough, and wherein the clipping system and the pair of elongate arms may be retracted into, and advanced from the lumen.
3. The system of claim 1 , wherein the first pair of elements comprise a first pair of prongs, and the second pair of elements comprise a second pair of prongs.
4. The system of claim 3 , wherein the first pair of prongs project toward the second pair of prongs.
5. The system of claim 4 , wherein the first pair and the second pair of prongs penetrate the pair of valve leaflets.
6. The system of claim 1 , wherein the pair of elongate elements are spring-biased to diverge outwardly when advanced distally from the tube.
7. The system of claim 1 , wherein the distal extremity of each of the pair of elongate elements comprise a trumpeted distal extremity.
