Abstract: An integrated circuit includes a capacitive sensing circuit to receive signal values associated with a proximity distance to an object. A pair of low pass filters (LPFs) are coupled in parallel to the capacitive sensing circuit and include a first LPF configured with a low filtering rate and a second LPF configured with high filtering rate that is higher than that of the low filtering rate. Control logic is coupled to the pair of LPFs and estimates the proximity distance based on one or more filtered signal values received from the pair of LPFs. The logic causes the second LPF to filter the signal values while the proximity distance remains unchanged. The logic detects a change in the proximity distance beyond a threshold value. The logic causes the first LPF to filter a subsequent signal value received from the capacitive sensing circuit based on detecting the change.

Abstract: Devices and methods for vascular navigation, assessment, treatment and/or diagnosis are disclosed. The system generally comprises an elongate body sized for introduction and translation through a catheter lumen. One or more openings may be located at or in proximity to a distal end of the elongate body and a sensor is positioned at or in proximity to the distal end.

A controller in communication with the sensor is configured to receive a signal indicative of the at least one parameter and is further configured to obtain a position of the sensor within a body of a subject based upon the signal.
