Abstract
An improved camming stem system including a head member, a plurality of cam lobes, a connection system, and a retraction system. The cam lobes may be selectively rotatable between an extended state and a retracted state with respect to at least one axle of the head member. The connection system may create an elongated, substantially rigid region by intercoupling the head member with a loop. The connection system is configured to create an elongated partially rigid region by intercoupling the head member with a loop, wherein the connection system comprises a twisted cable coupled between the head member and the loop, and wherein the loop is oriented substantially parallel to the at least one axle, and wherein the twisted cable includes a twisting radial angle of at least 90 degrees.
