Joining devices, kits and methods

1. A device comprising:

a flexible tube comprising a first collapsible end portion, a first end portion and a second end portion;

a first actuating element segment secured to the first collapsible end portion and extending along the first collapsible end portion,

wherein, when the first collapsible end portion is threaded through a first aperture and the first actuating element segment is pulled proximally, the first collapsible end portion collapses proximally and forms a bulge larger than the first aperture, thereby anchoring the flexible tube against a rim of the first aperture,

wherein said first actuating element comprises a thread or a rigid roll, said first end portion comprises a first elongated hardened element, and said second end portion comprises a second elongated hardened element, wherein said second elongated hardened element is threaded on the said second end portion by a loop.

2. The device of claim 1 , wherein said first elongated hardened element is located at a tip of the said first end portion.

3. The device of claim 1 , wherein the first and second end portions are a tubular mesh.

4. A method for closing a gap between a first object and a second object, the method comprising:

connecting the firt object and the second object with the device of claim 1 , thereby closing a gap between the first object and the second object.

5. The method of claim 4 , wherein said gap is a tear in meniscus tissue, said first object is a proximal wall of said meniscus tissue and said second object is a peripheral distal wall of said meniscus tissue.

6. The method of claim 5 , further comprising puncturing the meniscus tissue, wherein puncturing the meniscus tissue is performed by two tubular needles of an applicator.
