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.

-30. (canceled)
An implantable flow restriction system comprising:
- an implant comprising:
- an expandable body having a proximal end and a distal end and a lumen extending longitudinally therethrough;
- and
- a flow restrictor configured to be secured within a vessel of a patient's vasculature;
- and
- an implantable control unit comprising:
- an actuator configured to operably connect with the flow restrictor of the implant;
- a processor configured to receive an instruction to actuate the actuator;
- and
- a communication module operably connected to the processor and configured to wirelessly communicate with an external device;
- wherein actuation of the actuator causes the flow restrictor to pull in a wall of the vessel to at least partially restrict flow through the lumen.
A method of controllably and selectively occluding, restricting and/or diverting flow of a patient's vasculature, the method comprising:
- executing, by an implantable controller, an instruction to activate an implant implanted in a vessel of the patient's vasculature, wherein the implant comprises an expandable body having a proximal end and a distal end and a lumen extending longitudinally therethrough and a flow restrictor configured to be secured within the vessel of the patient's vasculature;
- and
- activating the implant;
- wherein activating the implant causes the flow restrictor to pull in a wall of the vessel to at least partially occlude flow through the lumen.
