摘要：
Improved catheter devices for delivery, repositioning and/or percutaneous retrieval of percutaneously implanted heart valves are described, including a medical device handle that provides an array of features helpful in conducting a percutaneous heart valve implantation procedure while variously enabling radial expansion or contraction and/or lateral positioning control over the heart valve during the medical procedure.
