摘要：
An obturator for marking an intracorporeal site includes an elongated shaft having an inner lumen, a proximal end, and a substantially closed distal end, the substantially closed distal end being formed of a penetrable membrane. A stylet has an MRI detectable distal shaft portion configured for removable insertion into the inner lumen of the elongated shaft to a location proximal to the penetrable membrane. The MRI detectable distal shaft portion is configured to not interfere with magnetic resonance imaging of tissue proximate thereto.
