Abstract: A medical system for removing far-field signals from a unipolar electrical signal is disclosed. In embodiments, the medical system comprises a catheter and a processing device communicatively coupled to the catheter. The catheter comprises a plurality of electrodes configured to sense a plurality of unipolar signals transmitted through tissue. The processing device is configured to: receive the sensed unipolar electrical signals, determine an electrode having a high level of contact with the tissue, and determine an electrode having a lower level of contact with the tissue than the electrode having the high level of contact with the tissue. Further, the processing device is configured to determine a sensed near-field electrical signal based on the unipolar electrical signal received from the electrode having the high level of contact and the unipolar electrical signal received from the electrode having the lower level of contact.

Abstract: Catheters and methods are provided for determining a fluid flow rate of fluid located near a tip assembly of the catheter and providing an indication of the fluid flow condition and/or controlling one or more functions of the catheter based on the determined fluid rate. A method includes receiving a signal from a sensor located on a tip assembly of a catheter, the signal being indicative of a fluid flow condition of fluid located near the tip assembly. A processing device determines the fluid flow condition using the signal. Based on the determined fluid flow rate, the processor causes a device to output an indication of the determined fluid flow condition.

Abstract: A catheter system includes a catheter comprising a tip assembly, the tip assembly having a plurality of electrodes and the plurality of electrodes are configured to measure electrical signals. The system also includes a processing unit configured to: receive a first electrical signal sensed by a first electrode of the plurality of electrodes and a second electrical signal sensed by a second electrode of the plurality of electrodes. A first vector is determined based on the first electrical signal that corresponds to the first electrode. A second vector is determined based on the second electrical signal that corresponds to the second electrode. A resultant vector is determined by summing at least the first vector and the second vector, wherein the resultant vector is indicative of the orientation of the tip assembly.
