Removable deployment device, system, and method for implantable prostheses

A medical device comprising:

• a mesh prosthesis comprising:
• a first layer having an opening therein;
• a second layer secured to the first layer and forming a pocket therebetween;
• and
• a deployment device positioned in the pocket and arranged to resiliently exert a deployment force on the mesh prosthesis to urge the mesh prosthesis toward a deployment shape, the deployment device having a first shape when fully deployed that has at least one dimension larger than that of the opening to restrict removal of the deployment device therethrough;
• wherein upon application of a suitable pulling force the deployment device is reconfigurable into a second shape that permits the deployment device to be removed from the pocket through the opening upon application of the suitable pulling force, wherein the deployment device has a separation line arranged in a serpentine configuration, such that application of the suitable pulling force causes the deployment device to reconfigure into the second shape by unraveling along the separation line.
