Sheath for percutaneous cable insertion (SPCI)

1 . A cable passer sheath configured to engage an end hole of a cable passer, the cable passer sheath comprising an outer body having an outer diameter and having a cable passer engagement opening at a cable passer engagement end thereof and a cable engagement opening at a cable engagement end thereof, wherein the cable passer engagement opening and cable engagement opening are connected by an inner passage through the outer body, wherein the inner passage has a first inner diameter less than the sheath outer diameter and a second inner diameter greater than the first inner diameter, and wherein the second inner diameter is sized to fit around an outer diameter of an end hole of a cable passer, wherein the sheath includes a center axis therethrough,

wherein a sheath inner diameter edge extends between the first inner diameter and second inner diameter, wherein when viewed through a cross section, the sheath inner diameter edge on either side of the center axis is angled with respect to a single line through the sheath that is angled with respect to the center axis, wherein the single line is coincidental with the sheath inner diameter edge on both sides of the center axis;

wherein the angle is approximately 45 degrees.

2 . The cable passer sheath of claim 1 , wherein the first inner diameter is sized to be equal to or less than the end hole outer diameter.

3 . The cable passer sheath of claim 2 , wherein the first inner diameter is configured to be the same as an inner diameter of the cable passer end hole.

4 . The cable passer sheath of claim 1 , further comprising a slit cut through the outer body to the passage.

5 . The cable passer sheath of claim 4 , wherein the slit extends along only a portion of a length of the outer body.

6 . The cable passer sheath of claim 1 , wherein the cable passer engagement end includes a beveled edge.

7 . The cable passer sheath of claim 1 , wherein the sheath inner diameter edge is configured to engage the entirety of a cable passer end's beveled edge.

8 . An operating equipment system including the cable passer sheath of claim 1 , further comprising the cable passer.

9 . The operating equipment system of claim 8 , wherein the cable passer includes a beveled edge and the sheath inner diameter edge engages the entirety of the beveled edge.
