A catheter includes: a shaft for insertion into an organ of a patient, and first and second position sensors. The shaft includes: (a) an inner shaft, which is configured to be deflected relative to an axis of the shaft, and (b) an outer shaft, which is coupled to a distal tip of the catheter and is configured to be: (i) coaxially disposed around the inner shaft, (ii) deflected together with the inner shaft, and (iii) rotated about the axis relative to the inner shaft. The first position sensor is coupled to the distal tip and is configured to produce a first signal, and the second position sensor is coupled to the inner shaft, and is configured to produce a second signal.

A cable, an associated monitoring system and methods are provided which monitor the continuity of current of electrical components such as sensor signals from sensors used in connection with a medical apparatus. The cable includes a proximal end for coupling with a processing unit and a distal end with or for coupling to sensors. The processing unit generates a continuity signal that travels through the cable via an inductor coil conductor to a distal end inductor coil which imparts the signal to sensor signal conductors of the cable. The continuity signal is carried back to the processing unit with signals from the sensors. Circuitry of the processing unit can detect the returning continuity signals to indicate proper connectivity of the sensor signals. The connection status information of the sensors can be displayed to inform a doctor or other operator of the medical apparatus of sensor signal continuity.

Cable and associated continuity monitoring system and method

Electrical apparatus includes a probe, having a proximal end and a distal end. The probe includes a sensor, which outputs a sensor signal, and a first connector at the proximal end of the probe, electrically coupled at least to the sensor. A probe adapter includes a second connector, which is arranged to mate with the first connector, and a third connector, for coupling to a console. A shield includes a material of high magnetic permeability, which is configured to enclose an internal volume containing the first and second connectors when the probe is connected to the probe adapter.

A linked list buffer circuit can be configured to store different linked lists. The buffer includes insert logic and an insert state machine to add ATM cells to the linked lists in the buffer. Extract logic and an extract state machine allow for the removal of ATM cells from the linked lists in the buffer. Because, ATM cells can have different levels of priority, programmable monitor circuitry is provided to monitor the linked lists in the buffer. The monitor circuitry keeps track of buffer and list capacity, and also keeps track of cell loss priority and delay priority cells of the buffer and the linked lists. This information is used to drop received cells if necessary. The linked list monitor circuitry can be configured based upon the linked list configuration of the buffer. The linked list monitor can be configured by changing threshold levels provided to counter/comparator circuitry. Assignments of internal counter circuitry are also programmable based upon the buffer configuration.

ATM linked list buffer system

An ATM buffer system includes a buffer to communicate with 16 ATM ports, and the system can implement two buffers to communicate over 32 ATM ports. A flow control signal is provided between the buffers in the 32-port configuration to route a buffer status signal to an ATM matrix using overhead data. The multiple buffers communicate with the ATM matrix using a single low voltage differential signal (LVDS) transmit and receive connection.
