Occlusion devices and methods of use thereof

An occlusion device configured to cause embolization of a blood vessel, the occlusion device comprising:

• a body having a distal portion and a proximal portion;
• a pair of lobes, one of the pair of lobes is positioned at the distal portion of the body and the other one of the pair of lobes is positioned at the proximal portion of the body, each lobe of the pair of lobes is shaped to circumferentially contact a vessel wall of the blood vessel to occlude the blood vessel;
• and
• the body comprising an adjustment assembly positioned between the distal portion and the proximal portion to change a distance between the pair of lobes, the adjustment assembly having:
• a receiving member having a first end, a second end, and an inner diameter, the second end having a flange that extends radially inward into the inner diameter;
• and
• an elongated member having a first terminating end, an opposite second terminating end, and an outer diameter, the first terminating end having a protrusion that extends radially outward from the outer diameter,
• wherein the elongated member is configured to move the body between an extended position and a retracted position, such that in the retracted position, the elongated member is received within the inner diameter of the receiving member such that the protrusion is spaced apart from the flange, and in the extended position, the elongated member is extended away from the first end of the receiving member such that the second end of the receiving member and the first terminating end of the elongated member are adjacent and the protrusion abuts the flange such that the distance between the pair of lobes is increased.

A method for embolization of a blood vessel, the method comprising:

• inserting, by a delivery device, an occlusion device into the blood vessel, the occlusion device having a body and a pair of lobes, the body has a distal portion and a proximal portion, one of the pair of lobes is positioned at the distal portion of the body and the other one of the pair of lobes is positioned at the proximal portion of the body;
• positioning the occlusion device at a target location;
• deploying one of the pair of lobes within the blood vessel such that the one of the pair of lobes circumferentially contact a diameter of the blood vessel to provide a radial force for stability at the target location;
• adjusting a distance between the pair of lobes of the occlusion device via an adjustment assembly such that the pair of lobes are positioned on either side of the target location;
• and
• deploying the other one of the pair of lobe s within the blood vessel such that the pair of lobes circumferentially contact the diameter of the blood vessel to inhibit a blood flow at the target location and to provide the radial force for stability at the target location.
