Abstract: An intravenous ultrasound (IVUS) system can include a catheter and a translation mechanism for translating the catheter. Engagement between the catheter and the translation mechanism may be detected, and the translation mechanism can be placed in a connected or disconnected mode, accordingly. When in connected mode, certain IVUS operations may be enabled when compared to disconnected mode, wherein such operations may be disabled. Thus, some embodiments may ensure proper engagement between the catheter and the translation mechanism prior to allowing certain IVUS operations to be carried out.

Abstract: An intravenous ultrasound (IVUS) system can include a catheter which can include memory. Because portions of the catheter are in intimate contact with the patient, electrical signals are isolated for safety. The IVUS system or catheter can thus comprise a catheter interface which provides bidirectional isolation circuitry for coupling the catheter to additional components of the IVUS system. Such circuitry allows for memory operation and communication from within the catheter while remaining electrically isolated. Catheter memory can contain information specific to the catheter such as the type of catheter, information regarding catheter components, information regarding catheter use, and other information useful for catheter operation.

Abstract: The system (2) includes a catheter drive unit (22) and a catheter (24) extending therefrom movably mounted to a catheter drive sled (26). The catheter drive unit rotates and translates the catheter core (34) within the catheter sheath (36). The sled has a serrated, conical drive unit interface (82), with a bag-piercing tip (86) mateable with a translator drive output (92) so that a sterile drape (112) enclosing the catheter drive unit is automatically pierced when the catheter drive unit is mounted to the sled. A control unit (6) is spaced apart from the catheter drive unit and provides power and commands to the catheter drive unit and receives information and data from the catheter drive unit. The rotator and translator drive motors (54, 90) are operated from both the control unit and the catheter drive unit. Both the control unit and catheter drive unit have translation displacement displays (10, 30).

Abstract: A secure circuit assembly includes a printed circuit board including first and second surfaces and a secure boundary area in the first surface. A circuit to be protected is located in the secure boundary area. A first inner enclosure is attached to the first surface of the printed circuit board and covers the secure boundary area in the first surface. A first sensor film is attached to the first inner enclosure and is electrically coupled to the printed circuit board. The secure circuit assembly also includes first and second outer enclosures, the first outer enclosure covering the first inner enclosure and the second outer enclosure covering the second inner enclosure. A method for providing security to a circuit assembly is also disclosed.
