摘要:
An embolic device deployment system includes a catheter having a first lumen and proximal and distal ends. A notch is disposed in the first lumen, forming a second lumen. An embolic device has a retaining ring at the proximal end. An engagement member includes a distal loop extending through the retaining ring, and a proximal loop extending into the first lumen. An elongated detachment member can be disposed through the loops and have a detachment member bump disposed between the loops. When the detachment member is disposed within the distal loop and the distal loop is disposed within the retaining ring, the embolic device is engaged. When the detachment member is pulled proximally, the detachment member is withdrawn from the distal loop, and the detachment member bump contacts the proximal loop. These acts assist in the disengagement of the distal loop from the retaining ring to release the embolic device.
