A steerable shaft of a medical instrument is steered by one or more control cables. The control cables are in contact with a steering system tension control device that reduces the tension in the control cables caused by bends in the shaft.

Sterilization devices and methods for deploying porous implants within the fallopian tubes are disclosed. The devices include a catheter component including an external electrode sheath containing at least two deployable implants and a positioning member. Sliding the external sheath proximally disposes the implants within the fallopian tubes, while sliding both the positioning member and external electrode sheath distally reloads a second implant into the external electrode sheath. The devices further includes a handle component, which houses a chassis, external electrode sheath carrier, reciprocating shaft, positioning member carrier and first and second engaging members. The reciprocating shaft may be operated by a motor to slide distally and proximally along a long axis. The reciprocating shaft, external electrode sheath and its carrier, upon selective actuation, move together proportionally to deploy and reload the implants to facilitate occlusion of the fallopian tubes and complete sterilization.
