Embodiment Construction

[0139] The devices, kits and methods disclosed herein can be used for anchoring in a variety of industrial and medical fields. Typically, the devices disclosed herein may comprise an elongated tube (hollow or solid) and an actuator fixed to the end of the elongated tube; said end portion of the tube can be inserted into the hole and the actuator can then be pulled . During this pulling process, a portion of the elongated tube may contract (eg, multiple folds one over the other) and form a bulged portion that acts as an anchor on the opposite side of the hole.

[0140] The anchor can be used to firmly fix the tube in question on the element on which the hole sits. Optionally, to release the anchor, the actuator can be pushed, thereby lengthening the collapsible portion of the tube and eliminating the expanded portion.

[0141] In more complex versions of the device, 2 or more such bulges may be formed in different regions of the tube, for example at 2 opposite ends of the tub...

Abstract

The present invention provides a device comprising: a hose comprising a first retractable end portion; a first actuator section fixed to said first retractable end portion and extending along said first retractable end portion; a retracted end portion extending; wherein said first retractable end portion is proximally retracted when said first retractable end portion is passed through a first aperture and said first actuator segment is drawn proximally and forming a larger bulge than said first hole, thereby anchoring said hose to the edge of said first hole.

Description

Background technique [0001] In humans, the two knee menisci are located between the femur and tibia. While the ends of the femur and tibia have a thin covering of soft hyaline cartilage, the menisci are formed of tough fibrocartilage and conform to the surface of the bone on which the meniscus rests. One meniscus rests on the medial plateau of the tibia, this is the medial meniscus. The other meniscus rests on the lateral plateau of the tibia, which is the lateral meniscus. [0002] These menisci help weight pass over the knee joint. Without a meniscus, the weight of the body would be unevenly placed on the femur and tibia. This uneven weight distribution leads to the development of abnormally excessive forces that lead to early damage to the knee joint. The meniscus also contributes to the stability of the joint. [0003] The meniscus is nourished by small blood vessels, but has no direct blood supply in the larger area in the center. The above situation becomes problem...
