Abstract
A collapsible device, such as an annuloplasty ring or prosthetic heart valve, is configured to be collapsed prior to being introduced into a patient via minimally-invasive access points such as port holes or intercostal incisions. A holder is configured to hold the collapsible device, and to selectively collapse the device for introduction into the patient and then re-enlarge the device at the desired deployment site. Collapsible devices include devices that can hingedly fold about hinge lines, and devices that can elongate to form substantially spiral forms with reduced diameters.
