Abstract

An insertion tool for deploying a flip anchor cable, including: a mechanism having a safety button and a slider, wherein the mechanism is configured to apply a clamping force on a portion of the flip anchor cable when the mechanism is in a first position; an inner tube having a proximal end connected to the mechanism configured to house a second portion of the flip anchor cable; a handle including a safety button opening and a slider opening, wherein the handle is configured to enclose a portion of the mechanism; and an outer tube having a proximal end connected to the handle configured to receive the inner tube; wherein the mechanism is configured to decrease the clamping force on the flip anchor cable when the mechanism is in a second position and to deploy a flip anchor of the flip anchor cable in the second position.

First claim

What is claimed is:

1. An insertion tool, comprising:
a flip anchor cable including a flip anchor, a cable rod, and a cable connected to the flip anchor at a distal end and connected to the cable rod at the proximal end;
a mechanism having a safety button and a slider, wherein the mechanism is configured to apply a clamping force on a first portion of the flip anchor cable when the mechanism is in a first position;
the mechanism further comprises a button support member connected to the safety button and the slider, a central support member flexibly connected to the button support member, a cable retaining member flexibly connected to the central support member, and a locking member connected to the cable retaining member configured to engage a single-use stop on the handle of the insertion tool, wherein the locking member is configured to engage the single-use stop in the position to prevent the mechanism from returning to the first position;
an inner tube having a proximal end connected to the mechanism configured to house a second portion of the flip anchor cable;
a handle including a safety button opening and a slider opening, wherein the handle is configured to enclose a portion of the mechanism, the safety button is engageable with the safety button opening to prevent movement of the mechanism relative to the handle, and the slider is configured to slide the mechanism along the slider elongated opening upon pressing the safety button to disengage the safety button opening; and
an outer tube having a proximal end connected to the handle configured to receive the inner tube;
wherein the mechanism is configured to decrease the clamping force on the flip anchor cable when the mechanism is in a second position and to deploy the flip anchor of the flip anchor cable in the second position.

2. The insertion tool of claim 1 , wherein the flip anchor includes a proximal end that is inside a distal end of the outer tube to secure the flip anchor.

3. The insertion tool of claim 2 , wherein the flip anchor includes a shoulder adjacent the proximal end wherein the shoulder is configured to engage a distal end of the inner tube and wherein the distal end of the inner tube pushes the shoulder to move the flip anchor out of the distal end of the outer tube when the mechanism slides from the first position to the second position when a sliding force is applied to the slider.

4. The insertion tool of claim 3 , wherein the flip anchor deploys by the proximal end of the flip anchor rotating away from the cable when the distal end of the inner tube pushes the shoulder to move the flip anchor out of the distal end.

5. The insertion tool of claim 1 , wherein the housing is configured to enclose a third portion of the cable and the cable rod.

6. The insertion tool of claim 1 , wherein the mechanism further comprises
a safety button protrusion; and
a safety button retainer configured to engage the safety button protrusion when the safety button is depressed to fix the safety button in a depressed position.

7. The insertion tool of claim 6 , wherein the safety button in the depressed position allows the mechanism to be placed in the second position by the application of a sliding force on the slider.

8. The insertion tool of claim 1 , wherein the cable retaining member further comprises a cable retaining protrusion connected to the cable retaining member, wherein the cable retaining protrusion is configured to apply the clamping force on the flip anchor cable in the first position.
