KIT COMPRISING A MEDICAL FIXING ELEMENT AND A DEVICE FOR PLACING SAID FIXING ELEMENT

The kit ( 1 ) comprises a needle ( 3 ) for placing the fixing element ( 2 ), and the fixing element ( 2 ) comprises at least one stop part ( 5 ) and a threaded deformable part ( 7 ) joined to said stop part ( 5 ). According to the invention, the needle ( 3 ) and the fixing element ( 2 ) comprise means ( 3, 10; 30 ) for detachably connecting the stop part ( 5 ) to the proximal part ( 15 ) of the needle ( 3 ), said connection being solid enough to enable the stop part ( 5 ) to remain integral with the needle ( 3 ) during the manipulation of the kit ( 1 ) when said kit ( 1 ) is handled, also enabling it to be introduced into the body of a patient and enabling the needle ( 3 ) to be introduced into a wall ( 50 ), said connection, however, being able to be released when a traction force is exerted upon the needle ( 3 ), in the direction in which the needle is inserted, beyond a force threshold which is greater than the stress exerted upon the fixing element ( 2 ) as a result of said manipulation, whereby release of the fixing element enables the stop part ( 5 ) to be brought into a non-deformed position by means of elastic recall of said connection.
