Abstract

Provided is a surgical instrument including an external tube (2) and two elongated members (4) positioned in the tube (2), each of which includes a distal end (10a) for capturing one of the two tissue zones (M1, M2) to be attached. The instrument (1) may further include a catching member (22, 25) for each tissue (M1, M2) to be attached; a rod (15, 16) linked to each catching member (22, 25) enabling tension to move axially, the 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 (17a) forming a stop for locking axially each catching member (22, 25) during the tensioning.

Claims

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

a pair of elongate elements, wherein the pair of elongate elements are extensible from a distal end of the tube, wherein each elongate element of the pair of elongate elements is adapted to grasp a valve leaflet of the pair of valve leaflets when vacuum is applied thereto, wherein the pair of elongate elements are configured to draw the grasped pair of valve leaflets together.

2. The system of claim 1, wherein said system further comprises a plurality of rods slidably disposed within the tube.

3. The system of claim 2, wherein the first element is detachably secured to a first rod of the plurality of rods and the second element is detachably secured to a second rod of the plurality of rods.

4. The system of claim 3, wherein the first rod and the second rod are configured to slide relative to one another to thereby capture the pair of leaflets between the first element and the second element.

5. The system of claim 3, wherein the first rod is configured to slide relative to the second rod to thereby detach the first element.

6. The system of claim 3, wherein the second rod is configured to slide relative to a third rod of the plurality of rods to thereby detach the second element.

7. The system of claim 1, wherein each elongate element of the pair of elongate elements comprises a trumpeted distal extremity.

8. The system of claim 1, wherein the pair of elongate elements are resiliently biased away from one another.

9. The system of claim 1, wherein the pair of elongate elements are configured to retract within the tube to thereby draw the pair of elongate elements toward one another.
