Revision connectors, systems and methods thereof

1. A connector comprising:

a 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;

a first member having a cam surface, the first member being rotatably connected to the connector at a pivot point, the first member being adapted to releasably secure the first rod in the first passage, wherein the first member is a V-shaped member comprising a first leg and a second leg, the first leg extending from a first end proximate the pivot point to a second end being a free end extendable into the first passage, the first leg having a rod engaging surface, and the second leg extending from a first end proximate the pivot point to a second end being a free end, the second leg having the cam surface; and

a set screw having a tapered tip, and when the set screw is rotated, the tapered tip engages the cam surface having a corresponding taper; and

a second clamping portion having:

a second passage having a second longitudinal axis extending therethrough, the second longitudinal axis being parallel to the first longitudinal axis, and the second passage being sized to allow a second rod to be inserted thereinto along the second longitudinal axis.

2. The connector according to claim 1 , wherein the second clamping portion comprises a second member being adapted to releasably secure the second rod in the second passage.

3. The connector according to claim 2 , wherein the second passage is a closed opening having a generally circular through-opening.

4. The connector according to claim 1 , wherein the first member comprises a cam rotatable between a first rod unlocking position and a first rod locking position.

5. The connector according to claim 1 , wherein the set screw comprises a rotating portion adapted to engage the first member such that the first member is engageable with the first rod.

6. The connector according to claim 5 , wherein the first member locking portion is pivotally movable between a first rod unlocking position and a first rod locking position.

7. A connector comprising:

a body having a bottom surface and extending between a first end and a second end;

the first end having:

a generally U-shaped first opening extending from the bottom surface, the U-shaped opening being sized to receive a first rod extending therethrough along a first axis;

a member having a cam surface, wherein the member is a V-shaped member comprising a first leg and a second leg, the first leg extending from a first end proximate the pivot point to a second end being a free end extendable into the first opening to releasably secure the first rod to the body, and the second leg extending from a first end proximate the pivot point to a second end being a free end; and

a set screw having a tapered tip, and when the set screw is rotated, the tapered tip engages the cam surface having a corresponding taper; and

the second end having:

a second opening extending therethrough along a second axis, parallel to the first axis, the second opening being sized to receive a second rod.

8. The connector according to claim 7 , wherein the second opening is a closed opening having a generally circular cross-section.

9. The connector according to claim 8 , further comprising a second member extendable into the second opening to releasably secure the second rod to the body.

10. A method of adding a new construct to an existing construct comprising the steps of:

(a) providing a connector having a first connecting portion with an open connection and a second connecting portion having a closed connection with an axial passage extending therethrough;

(b) inserting the open connection over a first rod in the existing construct;

(c) securing the first connecting portion to the first rod by rotating a set screw having a tapered tip to engage a cam surface of a V-shaped cam, the V-shaped cam comprising a first leg and a second leg, the first leg extending from a first end proximate a pivot point to a second end being a free end, and the second leg extending from a first end proximate the pivot point to a second end being a free end, the second leg having the cam surface having a corresponding taper, thereby pivoting the cam against the first rod;

(d) inserting a second rod through the axial passage; and

(e) securing the second rod to the second connecting portion.

11. The method according to claim 10 , wherein step (e) comprises advancing a member into the axial passage and wherein the method further comprises:

(f) engaging the second rod with the member.
