Apparatus and method for catheter navigation and tip location

Devices and methods obtain and use endovascular electrograms in a number of clinical applications and settings. In one embodiment, methods for triggering analysis of an endovascular ecg waveform are based on the detection of a peak in a skin-based ecg waveform in order to determine a location of an indwelling medical device, such as a catheter. ...

Methods and apparatus for inserting multi-lumen split-tip catheters into a blood vessel

A method of performing a medical procedure, includes providing a catheter including a first lumen in fluid communication with a first distal opening and a second lumen in fluid communication with a second distal opening, advancing a distal end of a first intra-catheter stiffener element through the first lumen and out of the first distal opening, coupling the first intra-catheter stiffener element to the catheter, advancing a distal end of a second intra-catheter stiffener element through the second lumen and out of the second distal opening, coupling the second intra-catheter stiffener element to the catheter, and advancing the catheter into a patient.. . ...

Apparatus and method for catheter navigation using endovascular energy mapping

Devices and methods obtain and use endovascular electrograms (or electrocardiograms/ecgs) in a number of clinical applications and settings. In one embodiment, a method for locating an indwelling medical device within a vasculature of a patient includes identifying an endovascular ecg waveform complex from an endovascular ecg signal associated with the indwelling medical device, then calculating an absolute value of the energy of the endovascular ecg waveform complex over a predetermined segment thereof. ...

Devices and methods for endovascular electrography

A method for positioning an endovascular device in or near the heart using electrocardiogram (ecg) signals. The method includes receiving an endovascular ecg signal including a plurality of waveforms, processing the endovascular ecg signal to calculate a p-wave amplitude and a spectral power for each predetermined time period, determining a maximum p-wave amplitude and an associated maximum spectral power, associating the maximum p-wave amplitude and the maximum spectral power with a predetermined location in or near the heart, calculating a location based on a ratio of the p-wave amplitude to the maximum p-wave amplitude and a ratio of the spectral power to the maximum spectral power, and displaying the location to a user.. ...
