Abstract
Various systems, devices, components and methods are disclosed for controllably and selectively occluding, restricting, and/or diverting flow within a patient's vasculature. The flow restriction systems can include an implant having a flow restrictor and an implantable controller having an actuator for actuating the flow restrictor. The flow restriction systems can also include an external device for controlling operation of the implant via the implantable controller.

A method of controllably and selectively occluding, restricting and/or diverting flow of a patient's vasculature, the method comprising:
- measuring an inferior vena cava pressure from an implant implanted in the inferior vena cava of the patient upstream of renal veins of the patient;
- transmitting the inferior vena cava pressure from an implantable controller positioned within the patient to an external device;
- receiving, by the implantable controller from the external device, an instruction to activate the implant;
- and
- activating the implant;
- wherein activating the implant causes the implant to at least partially occlude blood flow through the inferior vena cava.
