1. A holding tool for facilitating removal of an implantable cardiovascular valve, the holding tool comprising:
- a first sliding member;
a second sliding member moveable relative to the first sliding member; and
a first articulating joint member connected to the first and second sliding members, said articulating joint member moveable between a collapsed position and an expanded position, wherein movement of the second sliding member relative to the first sliding member moves the first articulating joint member between the collapsed and expanded positions.
