Abstract
Delivery systems for implanting cardiac valve repair devices are disclosed herein. In some embodiments, a delivery system includes a delivery catheter, a hub shaft extending through the delivery catheter, and a core shaft extending through the hub shaft. The delivery catheter is configured to hold a valve repair device in a compressed configuration. The hub shaft includes a hub configured to releasably engage a first portion of the valve repair device, and the core shaft includes a plug configured to releasably engage a second portion of the valve repair device. When the valve repair device is unsheathed from the delivery catheter, the hub shaft and the core shaft are independently movable to axially elongate/compress the valve repair device. When the valve repair device is properly positioned, the hub can be actuated to release the first portion of the valve repair device, and the plug can be actuated to release the second portion of the valve repair device.
