A steerable multi-linked device. The device includes a first multi-linked mechanism and a second multi-linked mechanism. The first mechanism defines a first plurality of grooves. The second mechanism defines a second plurality of grooves. The first and second pluralities of grooves cooperate to define at least two working ports along a length of the device. At least one of the first and second mechanisms are steerable. 1a first multi-linked mechanism, wherein the first multi-linked mechanism comprises a first plurality of grooves; anda second multi-linked mechanism, wherein the second multi-linked mechanism comprises a second plurality of grooves,wherein the first and second pluralities of grooves cooperate to define at least two working ports along a length of the device.. A steerable multi-linked device, comprising: This application claims priority to, and is a continuation of U.S. patent application Ser. No. 13/469,797, filed on May 11, 2012, which is a continuation of U.S. patent application Ser. No. 11/838,519, filed on Aug. 14, 2007, now U.S. Pat. No. 8,192,422, which claims priority to U.S. Provisional Application No. 60/822,280, filed on Aug. 14, 2006, and U.S. Provisional Application No. 60/862,636, filed on Oct. 24, 2006, the disclosures of which are incorporated herein by reference in their entireties.This application discloses an invention that is related, generally and in various embodiments, to a steerable multi-linked device having multiple working ports.There are many types of steerable multi-linked devices, and such devices are utilized in a number of applications. For some of the applications, it is desirable to be able to pass a plurality of devices (e.g., a camera, a fiber optic, a surgical tool, etc.) from a first end of a steerable multi-linked device to a second end of the steerable multi-linked device. Although some steerable multi-linked devices define a center passage which extends from one end of the device to the other end of the device, ...
