1. A method of manufacturing a flow control assembly for use with an implantable medical device, the method comprising: fabricating a unitary structure corresponding to the flow control assembly, wherein the unitary structure includes a first actuation element, a second actuation element, a gating element, a first portion having an unrestrained end portion, and a second portion; and coupling the unrestrained end portion of the first portion to the second portion to form the flow control assembly, wherein: coupling the unrestrained end portion to the second portion induces strain in first actuation element and the second actuation element, and after the unrestrained end portion has been coupled to the second portion, (a) the first actuation element is configured to selectively move the gating element in a first direction in response to a reduction in the strain induced in the first actuation element, and (b) the second actuation element is configured to selectively move the gating element in a second direction, different than the first direction, in response to a reduction in the strain induced in the second actuation element.
