Abstract
An apparatus including a joint spacer for treatment of a joint of a human subject. The joint spacer includes a bioresorbable stent having compressed and expanded configurations and a covering that covers an external surface of the stent. The joint spacer is configured to be inserted into a space of the joint, and is shaped, when the bioresorbable stent is in the expanded configuration, to provide mechanical support to the joint until the bioresorbable stent resorbs into a body of the subject. Treating a joint of a human subject includes inserting a joint spacer into a space of the joint while a bioresorbable stent of the joint spacer is in a compressed configuration, and transitioning the bioresorbable stent to an expanded configuration within the joint, such that the joint spacer provides mechanical support to the joint until the bioresorbable stent resorbs into a body of the subject.
