Abstract

An electrical lead anchoring assembly comprising a body comprising at least one recess and at least one channel there through for receiving at least one electrical lead, at least one arm pivotably coupled to the body and moveable between an open and a closed position wherein the arm is at least partially disposed within the recess such that the arm intrudes into the channel and frictionally abuts at least a portion of the length of electrical lead disposed in the channel to couple the lead to the body.

Claims

1. An anchoring assembly for anchoring an electrical lead having a length, the anchoring assembly comprising:

(a) a body, said body comprising

(i) an outer face,

(ii) at least one inlet,

(iii) at least one outlet,

(iv) at least one channel, said channel extending between the inlet and the outlet for

receipt of at least a portion of said length of lead, and

(v) at least one recess bounded on at least four sides by a first pair of surfaces of the body, which oppose and face each other, and a second pair of surfaces of the body, which oppose and face each other and each connect the first pair of surfaces, said recess opening into said outer face and into said channel, and

(b) at least one arm, said arm being pivotably coupled to said body and being moveable between an open and a closed position and bounded on at least four sides by the first pair of surfaces and the second pair of surfaces of the body, when in the closed position such that the arm intrudes into the channel, and said arm being at least partially disposed outside the recess while in the open position such that said length of lead may be inserted into the inlet, through the channel, and out of the outlet when the arm is disposed in the open position, the arm frictionally abutting at least a portion of the length of lead disposed in the channel when the arm is disposed in the closed position to secure the lead to the body,

wherein the arm comprises a top surface that is perpendicular to a plane of rotation defined by movement of the arm from the open position to the closed position and that is on an exterior of the arm when the arm is in the closed position, a bottom surface opposite the top surface and at least one side connecting the top surface to the bottom surface, wherein at least a portion of the at least one side of the arm intrudes into the channel when the arm is in the closed position, and wherein at least the portion of the at least one side of the arm frictionally abuts at least the portion of the length of lead disposed in the channel when the arm is disposed in the closed position to secure the lead to the body.

2. The anchoring assembly of claim 1 wherein the arm is parallel to the channel when the arm is disposed in the closed position.

3. The anchoring assembly of claim 1 wherein the arm is disposed substantially within the recess when in the closed position such that it does not extend above the outer face.

4. The anchoring assembly of claim 1 wherein the arm further comprises at least one protrusion, said protrusion presenting a frictional face for abutting the lead when the arm is disposed in the closed position.

5. The anchoring assembly of claim 1 further comprising a coupling structure, said coupling structure being adapted and disposed to pivotably secure the arm to the body.

6. The anchoring assembly of claim 5 wherein the coupling structure comprises at least one protrusion extending from at least one of the arm or the body, and at least one corresponding, second recess in the other of said arm or said body, said second recess receiving said protrusion to pivotably couple the arm to the body.

7. The anchoring assembly of claim 1 further comprising at least one pin, said arm comprising at least one depression adapted to at least partially receive said pin to pivotably couple the arm to the body.

8. The anchoring assembly of claim 1 wherein the body comprises at least one of a bore or a well adapted to receive a suture.

9. The anchoring assembly of claim 1 further comprising a latch disposed to couple the arm to the body in the closed position.

10. The anchoring assembly of claim 9 further comprising means for providing at least one of an audible signal or tactile feedback of when the arm is moved to the closed position.

11. The anchoring assembly of claim 9 wherein the arm is sufficiently flexible such that the arm may be resiliently flexed to release said latch.

12. The anchoring assembly of claim 1 further comprising a plurality of arms, and wherein the body comprises a plurality of channels adapted to receive a plurality of leads.

13. The anchoring assembly of claim 1 wherein the body comprises a base formed of a first material and an over molding disposed over the base, the over molding comprising a second material that is softer relative to the first material of the base.

14. The anchoring assembly of claim 1, wherein the arm is substantially completely contained within the recess, and bounded on at least four sides by the body, when in the closed position.

15. The anchoring assembly of claim 1, wherein the arm comprises a handle region that extends beyond the recess and the body.

16. The anchoring assembly of claim 1, wherein a surface of at least one side of the arm frictionally abuts at least the portion of the length of lead, and wherein the surface of the at least one side of the arm is parallel to a plane of rotation defined by movement of the arm from the open position to the closed position.

17. The anchoring assembly of claim 1, further comprising a second channel extending between a second inlet and a second outlet in the body for receipt of at least a portion of a second lead, wherein a first side of the arm intrudes into the first channel and frictionally abuts at least a portion of the length of the first lead disposed in the first channel when the arm is disposed in the closed position, and wherein a second side of the arm intrudes into the second channel and frictionally abuts at least a portion of the length of the second lead disposed in the second channel when the arm is disposed in the closed position.

18. The anchoring assembly of claim 1, wherein the at least one recess is open to the exterior of the body on fifth and sixth sides that are perpendicular to a plane of rotation defined by movement of the arm from the open position to the closed position.

19. An anchoring assembly for anchoring an electrical lead having a length, the anchoring assembly comprising:

(a) a body, said body comprising

(i) an outer face,

(ii) at least one inlet,

(iii) at least one outlet,

(iv) at least one channel, said channel extending between the inlet and the outlet for receipt of at least a portion of said length of lead, and

(v) at least one recess bounded on at least four sides by a first pair of surfaces of the body, which oppose and face each other, and a second pair of surfaces of the body, which oppose and face each other and each connect the first pair of surfaces, said recess opening into said outer face and into said channel, and

(b) at least one arm, said arm being pivotably coupled to said body and being moveable between an open and a closed position and bounded on at least four sides by the first pair of surfaces and the second pair of surfaces of the body, when in the closed position such that the arm intrudes into the channel, and said arm being at least partially disposed outside the recess while in the open position such that said length of lead may be inserted into the inlet, through the channel, and out of the outlet when the arm is disposed in the open position, the arm frictionally abutting at least a portion of the length of lead disposed in the channel when the arm is disposed in the closed position to secure the lead to the body,

wherein the arm comprises a top surface that is parallel to the outer face of the body and that is on an exterior of the arm when the arm is in the closed position, a bottom surface opposite the top surface and at least one side connecting the top surface to the bottom surface, wherein at least a portion of the at least one side of the arm intrudes into the channel when the arm is in the closed position, and wherein at least the portion of the at least one side of the arm frictionally abuts at least the portion of the length of lead disposed in the channel when the arm is disposed in the closed position to secure the lead to the body.
