Abstract
A conduit assembly for transmitting energy between an electrosurgical energy generator and an energy delivering device comprises a first cable sub-assembly including a cable having a flexibility and an energy attenuation; a second cable sub-assembly including a cable having a flexibility and an energy attenuation; wherein the flexibility of the cable of the first cable sub-assembly is less than the flexibility of the cable of the second cable sub-assembly; and wherein the energy attenuation of the cable of the first cable sub-assembly is less than the energy attenuation of the cable of the second cable sub-assembly.
Claims16
A cable assembly comprising:
- a reusable cable configured to operatively couple to an electrosurgical energy source;
- and
- a disposable cable configured to operatively couple the reusable cable to an electrosurgical energy delivery device, wherein an energy attenuation of the reusable cable is different from an energy attenuation of the disposable cable.
A cable assembly for transmitting electrosurgical energy, the cable assembly comprising:
- a reusable cable portion including a first inner conductor and a first outer conductor separated by a first dielectric material, the reusable cable portion removably coupleable to an electrosurgical energy source;
- and
- a disposable cable portion including a first end and a second end, the first end removably coupleable to a second end of the reusable cable and the second end of the disposable cable removably coupleable to an electrosurgical energy delivery device, the disposable cable including a second inner conductor and a second outer conductor separated by a second dielectric material, wherein an energy attenuation of the reusable cable portion is different from an energy attenuation of the disposable cable portion.
