Abstract
A vascular occlusion device includes an embolic device configured to be slidably received within and deployed from a catheter. The embolic device includes a wire having a primary shape when disposed within the catheter, and a secondary shape when released from the catheter. The primary shape is defined by a plurality of loops in a linearly expanded configuration, where all of the plurality of loops are longitudinally spaced apart and include upper loops and lower loops. In the secondary shape the upper loops are in a longitudinally overlapping configuration and the lower loops are in a longitudinally overlapping configuration.

An embolic device configured to be slidably received within and deployed from a catheter, the embolic device including a single wire having a primary shape when disposed within the catheter, and a secondary shape when released from the catheter, the single wire also having an intermediate shape when the single wire is transitioning from the primary shape to the secondary shape;
- wherein the primary shape is defined by a plurality of loops in a linearly expanded configuration, where all of the plurality of loops are longitudinally spaced apart and do not longitudinally overlap, all of the plurality of loops including upper loops extending above a longitudinal axis of the embolic device, and lower loops extending below the longitudinal axis;
- and
- wherein in the secondary shape the upper loops and the lower loops are in a longitudinally overlapping configuration;
- wherein the intermediate shape is different from the primary shape and the secondary shape is different from the intermediate shape.
A vascular occlusion system comprising:
- a catheter having a lumen with a delivery end;
- and
- an embolic device configured to be slidably received within and deployed from the lumen of the catheter, the embolic device including
- a single wire having a primary shape when disposed in the lumen of the catheter, an intermediate shape when first released from the delivery end, and a final secondary shape;
- wherein the primary shape is defined by a plurality of loops in a linearly expanded configuration, where all of the plurality of loops are longitudinally spaced apart and do not longitudinally overlap;
- wherein in the secondary shape the plurality of loops includes upper and lower loops in a longitudinally overlapping configuration.
A vascular occlusion system comprising:
- a catheter having a lumen with a delivery end;
- an embolic device configured to be slidably received within and deployed from the lumen of the catheter, the embolic device including a single wire having a primary shape when disposed in the lumen of the catheter, an intermediate shape when first released from the delivery end, final secondary shape, the primary shape defined by a plurality of loops in a linearly expanded configuration, where all of the plurality of loops are longitudinally spaced apart and do not longitudinally overlap, wherein in the secondary shape the plurality of loops include upper and lower loops in a longitudinally overlapping configuration;
- and
- a pusher member disposed within the lumen, the pusher member having a distal end configured to push a proximal end of the embolic device out of the lumen, wherein the pusher member and the embolic device are not coupled.
