Abstract: A catheter system which provides adjustability of the length of the guidewire extending distally from the distal tip of the catheter and/or allows the guidewire to be secured relative to the catheter hub to allow the guidewire and the catheter to be steered simultaneously. The catheter system may include a catheter having an elongate shaft defining a catheter lumen, a hub assembly coupled to the proximal end of the elongate shaft and including a hub assembly lumen, a torque assembly releasably coupled to the hub assembly and including a torque assembly lumen, and a guidewire co-axially disposed within the catheter lumen, hub assembly lumen, and torque assembly lumen. In a first configuration the torque assembly may be configured to simultaneously torque the elongate shaft and the guidewire and in a second configuration the torque assembly may be configured to torque the guidewire independent of the elongate shaft.

Abstract: The present invention relates to a device (10) for detecting a misuse of a medical imaging system (20), comprising a data interface (12) for acquiring medical image data (24) and audit log data (26) from the medical imaging system (20); a processing unit (14) which is configured to configured to analyse the medical image data (24) to determine whether or not a part of a fetus is imaged in the medical image data (24), to compare the medical image data (24) and the audit log data (26) with each other, and to determine based on said comparison whether there is a mismatch between the medical image data (24) and the audit log data (26); and a feedback unit (16) which is configured to generate a misuse alert signal if a mismatch is detected by the processing unit (14).
