摘要： A medical device delivery system including a delivery sheath that includes an internal lumen, and a plurality of delivery arms contained within the internal lumen of the delivery sheath and extending along a longitudinal axis of the internal lumen of the delivery sheath, wherein distal ends of the delivery arms include fasteners configured to engage with a basal structure of a medical device and a apical structure of the medical device, wherein the delivery arms are attached to delivery arm controls that are configured to advance the delivery arms and the medical device attached thereto out from a distal end of the delivery sheath, and removable release wires or release lines configured to engage with the fasteners to hold the basal structure and the apical structure in place at the fasteners. Also disclosed are methods of delivering a medical device to a subject including inserting a distal end of the medical device delivery system through an incision in the skin of subject, and deploying a medical device engaged with the delivery arms of the medical delivery system to within the body of the subject.
