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.

Various features are described that are adapted to improve performance of interference-relief type delivery systems. A delivery system provided herein comprises an implant comprising a socket at a proximal end of the implant; an elongate sleeve having (i) a proximal section, (ii) a distal section slidably disposed within the socket, and (iii) a window between the proximal section and the distal section, the window extending through a wall of the sleeve; and a core member having a proximal portion slidably received within the proximal section of the sleeve and a distal portion extending through the window to a space outside the sleeve and within the socket. The distal portion of the core member provides an interference fit with the distal section of the sleeve within the socket until the core member is withdrawn.

Interference-relief type delivery detachment systems

Embolic implants and methods of manufacture are disclosed. The implants may be used for occluding blood flow at endovascular sites. One use is in intracranial aneurysm emolization/occlusion and another in parent vessel occlusion (PVO) or sacrifice. Various features provide for improved use (e.g., regarding delivery, recapture, visualization and/or occlusion) and manufacturability.
