1. An adjustable medical device comprising:
a first tubular member having a first proximal end and a first distal end;
a second tubular member having a second proximal end and a second distal end;
a first connector affixed to the first proximal end and a second connector affixed to the second distal end, where the first connector and the second connector each have a plurality of splines and a plurality of slots, where both the plurality of splines and the plurality of slots extend helically along an axial direction to a free end of each of the first connector and the second connector, and where each spline in the plurality of splines is spaced apart from an adjacent spline by a slot from the plurality of slots;
wherein in a partially joined configuration, the plurality of splines and the plurality of slots from the first connector nests respectively with the plurality of slots and the plurality of splines from the second connector such that the plurality of splines of the first connector and of the second connector each alternatingly forms an exterior surface of a joined region of the first connector and the second connector, and where relative rotation in a first direction between the first connector and the second connector allows for engaging the first connector and the second connector in a fully joined configuration, and where relative rotation in a second direction allows for uncoupling of the first connector and the second connector; and
wherein the plurality of splines of the first connector radially overlap with the plurality of splines of the second connector such that the plurality of splines each have a superior edge and an inferior edge, where increase of a fluid pressure within the adjustable medical device forces the inferior edge of an adjacent spline against the superior edge to increase a fluid seal between the plurality of splines.
