A bioabsorbable clasp intended to be implanted to ligate a vessel (e.g., blood, lymphatic, or other tube-like structure) that does not require permanent occlusion after the surgical procedure, as the device is gradually degraded and digested by body tissues. The device is typically made of a polymer (e.g., polydioxanone), and may be radiolucent; a dedicated, disposable clip applier may be included.
