PERCUTANEOUS DELIVERY AND RETRIEVAL SYSTEMS FOR SHAPE-CHANGING ORTHOPEDIC JOINT DEVICES

摘要

A percutaneously implantable orthopedic device (100, 300, 570, 1100, 1200, 1600, 1700) is a shape-changing joint prosthesis with a generally arcuate or generally rectilinear configuration which is delivered through a delivery device (1000, 1801, 1901, 2001, 2210, 2310, 2800, 3101, 3401, 3501, 3701, 3801, 3901, 4001) in a substantially straightened or slightly curved configuration into a joint in a patient. One embodiment of a delivery and/or retrieval system for delivering or retrieving the shape-changing percutaneously implantable orthopedic device joint prosthesis can include a substantially straight (1030b, 1230b) or curved (1030c, 1230c) syringe, hypodermic needle or cannula that is joint expanding (2900), actuating, pivotable, can include a balloon (3000) and/or a loading device (2100, 2220, 2310, 2720, 3120, 3420, 3520, 3720, 3820, 3920) for storing the devices and orienting the device in the proper implantation orientation.
