Abstract
Abstract A double-apertured L-shaped crimp is crimped to one end of a cable. The other end of the cable is passed around the bone and an orthopedic device to be attached to the bone, and it is then passed through the other aperture in the crimp. A releasable, lever-operated cable clamp is installed on the cable, followed by a tensioning tool. The tensioning tool applies a pre-positioning tension on the cable. The cable clamp is clamped to the cable to hold the tension. The tool is removed for use on another cable. When ready for final tensioning, the tensioning tool is re-installed, adjusted to the desired final tension, the crimp swaged onto the cable to hold the final tension, the cable clamp unclamped, the tensioning tool released and removed with the cable clamp, and the cable is cut off at the crimp.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
160 words
A method for securing cable around bone and comprising the steps of: taking a cable having one end with a stop thereon, and passing the other end of the cable around the bone and returning toward the stop; feeding the other end of the cable through an aperture in the stop; feeding the other end of the cable through an aperture in a manually closable and releasable cable clamp and resting the clamp on the stop; engaging a cable tensioning tool with the clamp and with a portion of the cable between the clamp and the other end of the cable after the other end was fed through the aperture in the clamp; using the tool for applying positioning tension on the cable; temporarily fixing in the clamp aperture, that portion of the cable residing in the clamp aperture when the applied tension on the cable is at a desired positioning value; and removing the tensioning tool from the cable.
Claim 2
Independent Claim
160 words
A method for securing cable around bone and comprising the steps of: taking a cable having one end with a stop thereon, and passing the other end of the cable around the bone and returning toward the stop; feeding the other end of the cable through an aperture in the stop; feeding the other end of the cable through an aperture in a manually closable and releasable cable clamp and resting the clamp on the stop; engaging a cable tensioning tool with the clamp and with a portion of the cable between the clamp and the other end of the cable after the other end was fed through the aperture in the clamp; using the tool for applying positioning tension on the cable; temporarily fixing in the clamp aperture, that portion of the cable residing in the clamp aperture when the applied tension on the cable is at a desired positioning value; and removing the tensioning tool from the cable.
Claim 3
Dependent Claim
40 words
The method of claim 1 and wherein: the fixing step is performed by moving a lever on the clamp and thereby forcing a cam surface of the clamp into clamping relationship on the cable portion residing in the clamp aperture.
Claim 4
Dependent Claim
22 words
The method of claim 1 and wherein: the steps of passing and feeding and tensioning are performable without the cable contacting itself.
Claim 5
Dependent Claim
27 words
The method of claim 1 and further comprising the step of: fixing the location of the stop on the cable before passing the cable around the bone.
Claim 6
Dependent Claim
80 words
The method of claim 1 and further comprising the steps of: after removing the tensioning tool from the cable, re-installing the tensioning tool on the cable; operating the tensioning tool to establish the desired final tension in the cable; crimping the stop onto the cable to hold the cable from slipping in the stop; removing the cable clamp and the tensioning tool from the cable; and cutting off the cable at the location where the cable clamp engaged the stop.
Claim 7
Dependent Claim
33 words
The method of claim 5 and further comprising the step of: repeating steps of claim 1 on at least one other cable before the re-installing step of claim 3 on the first-mentioned cable.
Claim 8
Dependent Claim
34 words
The method of claim 5 and further comprising the step of: including an implant device; and passing the cable around the implant device before feeding the other end through the aperture in the stop.
Claim 9
Dependent Claim
55 words
The method of claim 5 and further comprising the steps of: after re-installing the tensioning tool; applying at least the same amount of tension on the cable in the tool as was established previously when the cable was previously tensioned; and releasing from clamping relationship to the cable, a clamping member in the cable clamp.
Claim 10
Dependent Claim
60 words
A surgical cabling assembly comprising: a crimp having an apertured crimpable portion; a cable having an end portion fixed with respect to the crimp and an end portion receivable through the aperture in the crimp; and a cable clamp having a lever-operated cam clamped to a portion of the cable which has been passed through the aperture in the crimp.
Claim 11
Dependent Claim
60 words
A surgical cabling assembly comprising: a crimp having an apertured crimpable portion; a cable having an end portion fixed with respect to the crimp and an end portion receivable through the aperture in the crimp; and a cable clamp having a lever-operated cam clamped to a portion of the cable which has been passed through the aperture in the crimp.
Claim 12
Dependent Claim
