This suit starts out as a straightjacket, restricting Isaac to only walking, running and opening doors until cut open by Foster Edgars. The modules were salvaged from medical machinery much like his makeshift Plasma Cutter and were used for therapy.

Isaac installs a Stasis Module and Kinesis Module to this suit during his hospital escape in Chapter 1. The Patient Suit is also equipped with drug injectors as it was seen via tubular attachments near the neck area of the RIG, most likely to keep the patients calm and relaxed. It seems to mostly be used to monitor the health and status of the hospital patients while restricting their movement when necessary. It is important to note that this suit has no helmet, stabilization thrusters or gravity boots, being designed only for hospital use. As expected, the Patient Suit gives no protection and has 10 inventory slots like the Level 1 RIG. It is dirty and gray and splattered with the blood of Franco Delille.

This 'suit' consists of a hospital outfit with a straightjacket attached. The 'Patient Suit' is Isaac Clarke's starting outfit in Dead Space 2.
