Abstract
A method and associated device for constricting fluid flow in vasculature comprising inserting a device into vasculature of a patient. The device comprising a frame defining an inflow portion, an outflow portion, and a center portion between the inflow portion and outflow portion and a fluid impermeable membrane lining at least the center portion, wherein a minimum diameter of the center portion is at least about 33% less than a diameter of the inflow portion, and the patient has deep vein reflux (DVR), chronic venous insufficiency (CVI), or excess shunting through a fistula. The method may further include placing the device within a vein proximally to a refluxing deep vein in a valve free zone.
Claims20
A device for correcting valvular insufficiency and reflux, comprising a stent frame comprising an inflow portion, a center portion, and an outflow portion, wherein the inflow portion and outflow portion have a diameter greater than a diameter of the center portion.
A device for constricting fluid flow in vasculature comprising:
- (a) a frame defining an inflow portion, an outflow portion, and a center portion between the inflow portion and outflow portion;
- (b) an fluid impermeable membrane lining at least the center portion;
- and
- (c) at least one barb disposed on the frame configured to engage a vascular wall,
- wherein a minimum diameter of the center portion is at least about 33% less than a diameter of the inflow portion.
A method for constricting fluid flow in vasculature comprising:
- inserting a device into vasculature of a patient, the device comprising:
- (a) a frame defining an inflow portion, an outflow portion, and a center portion between the inflow portion and outflow portion;
- and
- (b) a fluid impermeable membrane lining at least the center portion,
- wherein a minimum diameter of the center portion is at least about 33% less than a diameter of the inflow portion, and the patient has deep vein reflux (DVR), chronic venous insufficiency (CVI), or excess shunting through a fistula.
