摘要：
A delivery/recovery system to allow an operator to deploy and recover a medical implant, such as an occluder for closing a patent foramen ovale (PFO). In one embodiment, the system includes a delivery mandrel for preventing the occluder from moving in the proximal direction, a delivery wire for securing the occluder to the delivery mandrel and preventing unwanted movement in the distal direction, and a sheath for enveloping the delivery wire, mandrel and occluder. By moving the sheath relative to the occluder in a series of steps, the occluder opens first on a distal side and then on a proximal side, in a manner that holds the occluder in place.
