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.
Claims11
An implantable flow restriction system comprising:
- an implant comprising:
- an expandable body comprising a metallic frame having a proximal end and a distal end and a lumen extending longitudinally therethrough;
- and
- a flow restrictor comprising:
- a plurality of petals each formed by struts;
- and
- a material spanning each of the plurality of petals;
- wherein the flow restrictor is configured to hinge relative to the expandable body to at least partially restrict flow through the lumen;
- 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 at least partially restrict flow through the lumen;
- a tubing configured to connect the proximal end of the expandable body of the implant to the implantable control unit;
- and
- a shaft movingly disposed with the tubing configured to connect the actuator of the implantable control unit to the flow restrictor of the implant;
- wherein actuation of the actuator of the implantable control unit moves the shaft within the tubing to cause the flow restrictor of the implant to at least partially restrict flow through the lumen.
