Abstract
Features for a restraint, such as a cap, are described. The restraint secures a cardiac device in a collapsed, delivery configuration for transcatheter delivery to a heart. The restraint may have a tubular sidewall extending from a proximal end to a distal end, a proximal opening defined by the sidewall at the proximal end and a channel defined by the sidewall and extending distally from the proximal opening. The restraint is configured to receive the implant in the collapsed configuration through the proximal opening to radially restrain the implant within the channel. The restraint eliminates the need for a surrounding sheath, reducing the delivery profile and size of the overall delivery system, among other advantages. The restraint may have an atraumatic leading edge to reduce the risk of injury to the patient.
