1. A remote manipulation system for remotely manipulating an associated medical device that is movable between an expanded position and a collapsed position, the manipulation system comprising:
- (a) first manipulation means for minimally invasive or percutaneous collapse and withdrawal of the medical device, said first manipulation means including one or more first connection means for connecting to the medical device,said first manipulation means connecting with the medical device when said first manipulation means is in a first position, and said first manipulation means connecting with the medical device when said first manipulation means is in a second position,wherein said first manipulation means collapses the medical device when moved between the first position and the second position; and
(b) second manipulation means for minimally invasive insertion and expansion of the medical device, said second manipulation means including one or more second connection means for connecting to the medical device,said second manipulation means connecting with the medical device when said second manipulation means is in a first position, and said second manipulation means connecting with the medical device when said second manipulation means is in a second position,wherein said second manipulation means expands the medical device when moved between the first position and the second position.

7. A remote manipulation system for remotely manipulating an associated medical device that is movable between an expanded position and a collapsed position, the remote manipulation system comprising:
-
(a) a first manipulating device including a first engagement means for engaging the first manipulating means with the medical device, said first manipulating device engaging with the medical device when the first manipulating device is in a first position, and said first manipulating device engaging with the medical device when the first manipulating device is in a second position, wherein said first manipulating device collapses the medical device when moved between the first position and the second position, and (b) a second manipulating device including a second engagement means for engaging the second manipulating means with the medical device, said second manipulating device engaging with the medical device when the second manipulating device is in a first position, and said second manipulating device engaging with the medical device when the second manipulating device is in a second position, wherein said second manipulating device expands the medical device when moved between the first position and the second position. - View Dependent Claims (8, 9, 10)
