Abstract
An embolic coil delivery system includes a catheter and an embolic coil disposed within the catheter, the embolic coil including a coil wire and a fiber bundle. A method of producing an embolic coil delivery system includes: advancing a delivery sheath over a distal end of an embolic coil while applying tension to the embolic coil via a retaining device that is attached to the distal end of the embolic coil.
Claims20
An embolic coil system comprising:
- an embolic coil comprising:
- a first portion;
- and
- a second portion extending from the first portion;
- wherein the first portion and the second portion each have a primary shape and a secondary shape;
- wherein the first portion forms a spiral having a first diameter in the secondary shape;
- wherein the second portion forms a spiral having a second diameter smaller than the first diameter in the secondary shape;
- a donor wire having a proximal end coupled to a distal end of the embolic coil;
- and
- a pusher wire extendable through a catheter and having a distal end couplable to a proximal end of the coil.
