Abstract
One embodiment 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 retraction system is configured to selectively engage the retracted state with a trigger assembly which is slidably externally coupled to the connection system. The trigger assembly further includes a coupling member coupled with the plurality of cam lobes via a plurality of retractor wires, at least one trigger cable fixably coupled to the coupling member, a trigger coupled to the at least one trigger cable, a sleeve member intercoupled between the coupling member and the trigger.
