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.
Claims20
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;
- 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 include 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 are in a longitudinally overlapping configuration and the lower loops are in a longitudinally overlapping configuration.
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, and a secondary shape when released from the delivery end;
- 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;
- 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, and a secondary shape when released from the delivery end, 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, 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.
