Abstract
Disclosed embodiments and methods provide solutions for coupling and decoupling of a delivery device from a stented prosthetic heart valve with one or more release mechanisms. In situations when one or more sutures get tangled or caught upon attempted retraction of the delivery device and sutures after deployment of the stented prosthetic heart valve, a secondary release mechanism can be provided to sever the suture(s) or release the suture(s) from the delivery device. Exemplary secondary release mechanisms include high resistance inserts, cutters and balloon expandable devices. Methods of releasing the sutures from the delivery device or severing the suture(s) are also disclosed.
