about its longitudinal axis to guide the key profile of the liner string toward a narrowed region 160 that coincides with a longitudinal axis 150 of the deflector 40 the longitudinal axis 150 in turn coincides with the keyway profile 60 of the deflector 40 referring also to fig6 depicting a cross section of the deflecting face 42 along line 6 6 of fig5 in some embodiments of the invention the deflecting face 42 may include surfaces 162 and 164 that may be generally level as depicted in fig6 at the uphole end of the deflecting force 42 and increasingly slanted toward the longitudinal axis 150 at the downhole end of the deflecting face 42 it is noted that in some embodiments of the invention the surfaces 162 and 164 may not be inclined towards the longitudinal axis 150 the surfaces 162 and 164 follow the perimeter of the channel around the entry of the passageway 41 of the deflecting face 42 to meet at the longitudinal axis 150 at narrowed region 160 to guide the key profile 70 see fig2 of the liner string 30 toward the keyway profile 60 as a more specific example fig7 depicts the cross section of the deflector 40 shown in fig6 along with a cross sectional view of the liner string 30 during the initial engagement.
