Abstract:
1. A set of tools for facilitating removal of an implanted cardiovascular valve, the set of tools comprising: (a) a holding tool for holding the implanted cardiovascular valve, said holding tool including: a first sliding member; a second sliding member moveable relative to the first sliding member; and a first 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 member between the collapsed and expanded positions, said first member engageable with the implanted cardiovascular valve in the expanded position; (b) a cutting tool including: a hollow shaft having a longitudinal axis and defining a recess dimensioned to mount over said first and second sliding members of the holding tool, wherein said holding tool locates the cutting tool relative to the implanted cardiovascular valve; and a cutting arm extending radially from the shaft, wherein said cutting arm includes cutting means for cutting tissue surrounding the implantable cardiovascular valve, said cutting tool rotatable relative to said holding tool to form a generally annular recess around the periphery of the implantable cardiovascular valve; and (c) a valve removal tool including: a body having a recess dimensioned to mount over said first and second sliding members of the holding tool, wherein said holding tool locates the valve removal tool relative to the implanted cardiovascular valve; capture means mounted to the body and moveable between a collapsed position and an expanded position, for capturing the implanted cardiovascular valve; and an actuator for actuating movement of the capture means between the collapsed and expanded positions.
