Abstract
One embodiment of the present invention relates to 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 includes a cord continuously wrapped around the head member and loop. The continuous configuration of the cord around both the head member and the loop creates the necessary minimum tensile strength for operation of the camming system. The cord may be wrapped around a rivet or one or more axles of the head member. Independent regions of the cord may be spliced together to form the continuous configuration.
