Methods and devices are provided for performing minimally invasive surgical procedures. In one embodiment, a surgical device is provided that includes an elongate shaft having a distal portion configured to be movable between a first configuration in which the distal portion of the shaft is substantially straight or linear and a second configuration in which the distal portion of the shaft is bent at a compound angle. The shaft's distal portion can be configured to be articulated in a wide range of compound angles and can be configured to be selectively locked in a fixed position anywhere within that range.
