at the junction of spring portions 8 and 9 the position of cover 4 over anchor 100 limits possible dislodgement of anchor 100 from tool 1 during introduction into the tissue and protects the tissue from the anchor referring to fig8 b to deploy the anchor the operator first slides member 15 and thus cover 4 proximally to a position near the middle of the slidable range i e member 15 is near the middle of guide channel 41 and pin 12 is near the middle of cutout 130 pin 12 now contacts spring 5 at the junction of spring portions 9 and 10 and anchor 100 is partially uncovered since spring portion 9 is oriented parallel to the axis of elongate portion 13 the movement of pin 12 does not deflect spring 5 and spring 5 still rests against tissue anchor 100 without exerting a lateral force on the anchor referring to fig8 c and 9b to rotate anchor 100 arrow a the operator slides member 15 and thus cover 4 further proximally such that member 15 is in contact with proximal face 43 of guide channel 41 and pin 12 is near distal end 144 of cutout 130 anchor 100 is now fully uncovered the movement of pin 12 along sloped spring portion 10 laterally deflects spring 5 spring portions 8 and 9 are received within cover slot 20 and distal spring portion 6 exerts a substantially laterally directed force f on anchor 100 causing the anchor to rotate the rotation of tissue anchor 100 pivots anchor 100 within arms 119 120 the proximal translation of cover 4 thus both exposes and rotates anchor 100 referring to fig9 a and 9b in use e g in shoulder.
