1. A delivery system for implanting a medical device, comprising:
a delivery catheter having a proximal portion and a distal portion;
a connector mechanism having first arms and connectors, each first arm has a proximal portion coupled to the delivery catheter and a distal portion, and each connector is at the distal portion of a corresponding first arm and configured to engage the medical device;
a locking mechanism having second arms and retainers, each second arm has a proximal portion coupled to the delivery catheter and a distal portion, and each retainer is at the distal portion of a corresponding second arm and configured to maintain engagement between the connector and the medical device in a locked position; and
a universal joint between the delivery catheter and the first and second arms,
wherein each first arm is associated with a corresponding second arm to define pairs of first and second arms in which the first arm and/or the second arm move relative to each other to a released position in which the retainer of the second arm is moved from the connector of the corresponding first arm to release the medical device.
