A connector has a first end that clamps to a first rod in an existing construct and a second end, connected to the first end, that clamps to a second rod in a new construct such that the new construct can be extended from the existing construct at an adjacent level as the existing construct. ## Claims ### Claim 1 A connector comprising: a body having a first clamping portion and a second clamping portion; the first clamping portion having: a first passage having a first longitudinal axis extending therethrough and being sized to allow a first rod to be inserted therein; a bottom portion having an opening in communication with the first passage; and a first securing mechanism comprising a set screw, a clamp having two opposing legs, and an opening defined between the two opposing legs, the clamp being connected to the set screw and the set screw being rotatably connected to the body, the first securing mechanism having an unlocked position configured to receive the first rod and a locked position configured to releasably secure the first rod in the opening between the two opposing legs of the clamp and in the first passage; and the second clamping portion having: a second passage having a second longitudinal axis extending therethrough, the second longitudinal axis being substantially parallel to the first longitudinal axis, and the second passage being sized to allow a second rod to be inserted therein along the second longitudinal axis. ### Claim 2 (depends on 1) The connector according to claim 1, wherein, in the locked position, the two opposing legs move inwardly toward one another as the clamp is driven upward in the body. ### Claim 3 (depends on 1) The connector according to claim 1, wherein the first passage is defined by generally opposing sidewalls having one or more angled surfaces. ### Claim 4 (depends on 3) The connector according to claim 3, wherein the opposing sidewalls are angled such that a width of the opening is greatest at a bottom of the opening and decreases upward. ### Claim 5 (depends on 1) The connector according to claim 1, wherein the set screw is able to rotate independently from the clamp. ### Claim 6 (depends on 1) The connector according to claim 1, wherein an annular protrusion on an engagement end of the set screw is received in a recess in a top portion of the clamp. ### Claim 7 (depends on 1) The connector according to claim 1, wherein inner surfaces on the opposing legs of the clamp are textured to enhance the connection between the first rod and the clamp. ### Claim 8 (depends on 1) The connector according to claim 1, wherein the second clamping portion comprises a second securing mechanism being adapted to releasably secure the second rod in the second passage. ### Claim 9 (depends on 1) The connector according to claim 1, wherein the second passage comprises a generally circular through-opening. ### Claim 10 (depends on 1) The connector according to claim 1, wherein the second passage comprises a generally U-shaped opening. ### Claim 11 A connector comprising: a body having a first clamping portion and a second clamping portion; the first clamping portion having: a first passage sized and dimensioned to receive a first rod, and a transverse opening extending through and being in communication with the first passage; and a first securing mechanism comprising a set screw and a clamp having two opposing legs, and an opening defined between the two opposing legs, the clamp being connected to the set screw and the set screw being rotatably connected to the body, the set screw being received in an upper portion of the transverse opening and configured to allow the clamp to slidably translate through the transverse opening; and the second clamping portion having a second passage sized and dimensioned to receive a second rod. ### Claim 12 (depends on 11) The connector according to claim 11, wherein, in a locked position, the two opposing legs move inwardly toward one another as the clamp is slidably translated upward in the body. ### Claim 13 (depends on 11) The connector according to claim 11, wherein the transverse opening is defined by generally opposing sidewalls having one or more angled surfaces. ### Claim 14 (depends on 13) The connector according to claim 13, wherein the opposing sidewalls are angled such that a width of the opening is greatest at a bottom of the opening and decreases upward. ### Claim 15 (depends on 11) The connector according to claim 11, wherein the set screw is able to rotate independently from the clamp. ### Claim 16 (depends on 11) The connector according to claim 11, wherein an annular protrusion on an engagement end of the set screw is received in a recess in a top portion of the clamp. ### Claim 17 (depends on 11) The connector according to claim 11, wherein inner surfaces on the opposing legs of the clamp are textured to enhance the connection between the first rod and the clamp. ### Claim 18 (depends on 11) The connector according to claim 11, wherein the second clamping portion comprises a second securing mechanism being adapted to releasably secure the second rod in the second passage. ### Claim 19 (depends on 11) The connector according to claim 11, wherein the second passage comprises a generally circular through-opening. ### Claim 20 (depends on 11) The connector according to claim 11, wherein the second passage comprises a generally U-shaped opening.
