Abstract
An occlusion system provides a trimmable continuous embolic coil that is “cut to length” at the end of its deployment into the aneurysmal space. A delivery device provides the “cut to length” feature for the continuous embolic coil. A method of filling an aneurysmal space with a continuous embolic coil is also disclosed.
Claims20
A method of filling an aneurysmal space with continuous embolic coil, the method comprising
- loading a distal end of a continuous embolic coil into a delivery device;
- advancing the continuous coil into and through the delivery device from a coil dispenser;
- deploying a portion of the continuous embolic coil to a desired length into the aneurysmal space through the delivery device;
- determining whether a coil pack formed by the deployed portion of the continuous embolic coil is sufficient to partially or completely fill the aneurysmal space;
- cutting the continuous embolic coil at the desired length such that the deployed portion of the continuous coil is severed from the coil dispenser and a proximal portion of the continuous coil remains on the coil dispenser.
A method of occluding a target occlusion site with a continuous embolic coil, the method comprising
- advancing a distal end of a continuous embolic coil from a coil dispenser into and through a delivery device;
- deploying a portion of the continuous embolic coil into the target occlusion site through the delivery device;
- visualizing the coil pack to determine whether a coil pack formed by the continuous embolic coil is sufficient to partially or completely fill the occlusion site;
- cutting the continuous embolic coil such that the deployed portion of the continuous coil is severed and a proximal portion remains on the coil dispenser.
A system for filling an aneurysmal space, the system comprising a continuous radiopaque embolic coil configured to be cut to length and when deployed into the aneurysmal space, the coil transitions from a storage shape to a deployed shape to form, join or complete a coil pack.
