Abstract
A fastening device, comprising an inner tube comprising a proximal end and a distal end and at least one fastener positioned within the inner tube and adapted to advance linearly towards the distal end of the inner tube, and an advancing element which converts rotational motion to linear pushing force on the fastener. In some embodiments of the invention, at least one fastener is adapted to not rotate at all or to rotate at a rate not necessarily the same as any other fasteners or any other elements during linear advancement.
Claims30
A fastening device comprising:
- an inner tube comprising a proximal end and a distal end, the inner tube adapted to receive one or more fasteners;
- an advancing element which converts rotational motion of the inner tube to linear pushing force on said one or more fasteners towards the distal end of the inner tube,
- wherein the inner tube is loadable with at least one fastener which does not rotate during linear advancement,
- wherein at least one fastener of said fasteners has a geometry which matches the geometry of the inner tube so that it rotates with the inner tube during linear advancement.
A method of advancing a fastener, the method comprising:
- introducing a fastening device into a body, the device including an outer tube into which an inner tube is inserted, the inner and outer tube including a distal end and a proximal end and a first set of fasteners including one or more fasteners positioned in the inner tube;
- providing a rotational movement to the inner tube;
- and
- converting said rotational movement into a linear pushing force on said fasteners and linearly advancing said fasteners in the inner tube towards the distal end of the inner tube,
- wherein at least one of said fasteners has a geometry which matches the geometry of the inner tube so that it rotates with the inner tube during linear advancement, and
- wherein the outer tube is static and does not move with respect to other elements at the distal end of the device.
