Abstract: An apparatus and method establish a secure, direct, station-to-station communication between a first station and a second station in a topology (e.g., PBSS) having a central secret holder/provider that allows secure, direct, station-to-station communications and that allows secure station-to-station broadcast communications. The first station and the second station will have previously established a security association (SA) with a topology control point (PCP). The method includes creating pair-wise unique material for the first station. The pair-wise unique material is computed as a function of (i) a known shared secret associated with the PCP, (ii) a first piece of unique data associated with the first station, and (iii) a second piece of unique data associated with the second station. The method includes securely communicating the pair-wise unique material from the first station to the second station.

Abstract: A disposable system for safely deploying, retrieving and handling a trocar during open surgery. An embodiment comprises a dispenser handle that houses a trocar within a protective sheath during deployment of the trocar within the surgical wound area; and an adjoining receiver that provides a target, shield and active backstop when retrieving the trocar tip from the surgical site. The dispenser handle is shaped ergonomically for easy manipulation; contains a sheath to safely cover the trocar tip during manipulation; and integrates a coupler that permits independent motion between it and the sheath, while releasably gripping the trocar until deployed within the surgical site. The adjoining receiver is comprised of a compact receiver handle grip; an integrated trocar-locking mechanism that traps the trocar when extracting it, while trailing drainage tubing from the surgical site; and a removable safety shield.
