Disclosed are example embodiments of an endovascular coil having a twistedshape. The endovascular coil includes: a first loop; a second loop; and an inflection region where a portion of the first loop transitions into a portion of the second loop. The second loop is rotated about an axis parallel to the longitudinal axis of the first loop to create the twistedshape. The twist adds more randomness and variability to the filling behavior of the endovascular coil. The added randomness and variability enables the twistedcoil to better fill the void of irregular-shaped aneurysms than other conventional embolic coils.

Endovascular coil and method for making the same

An embolic device and a corresponding embolic device delivery system and method. In one example, an embolic device delivery system comprises a delivery catheter, a coupler disposed inside the delivery catheter, and an embolic device that may be carried and placed by the coupler. The embolic device includes a primary winding that forms a hollow tube such that a coupler may be threaded therethrough. Further, the embolic device may include a slotted metal tube suited to be affixed to one end of the hollow tube formed by the primary winding. Additionally, the embolic device may include a retaining mechanism that includes one or more protrusions suited to engage with one or more slots of the slotted metal tube. In this manner, the retaining mechanism is affixed to the slotted metal tube and the hollow tube formed by the primary winding.

Embolic device suited for ease of delivery and placement

A system and method for delivering an embolic device are disclosed. In one embodiment, the system and method may be directed to a combination of a catheter, coupler, and embolic device. The coupler is disposed inside of the catheter. The embolic device is coupled with a retaining mechanism at the proximal end. Until the embolic device is delivered to a certain location within an artery, the embolic device is engaged with the catheter by engaging the coupler with the retaining mechanism. The embolic device is further secured to the delivery catheter by securing the coupler with a securing mechanism formed on the catheter. When the delivery catheter reaches the desired location in the artery, the embolic device is released from the delivery catheter by simply pulling the coupler proximally such that the loop portion of the coupler first becomes disengaged from the locking window and then from the retaining mechanism.
