REMOVABLE DEPLOYMENT DEVICE, SYSTEM, AND METHOD FOR IMPLANTABLE PROSTHESES

摘要

Disclosed is 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. 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.
