4. Exchange the catheter for a pigtail catheter and remove the guidewire.

Ensure the pigtail catheter extends into the right PA as shown.

5. Inject contrast agent through the pigtail catheter to illuminate the

right pulmonary artery and provide a roadmap for identifying proper

Sensor deployment location. Using the markers on the pigtail (10mm

spacing) estimate the diameter of the right PA main vessel at the

downturn. The vessel at this location must be between 12-30mm. If

the vessel appears to be either larger or smaller than the indicated

range, abort the procedure and DO NOT implant the Cordella Sensor.

12-30mm dia.

6. Introduce a guidewire (.018”-.025”, 260cm-300cm) through the

lumen of the pigtail catheter extending into the right pulmonary

artery. Ensure that the wire follows the main branch of the right

pulmonary artery and remains in the main branch for appx. 6cm

beyond the downturn.

7. Remove the pigtail catheter, leaving the guidewire in place.

WARNING: Ensure that the guidewire is in the main

right pulmonary artery distal to the implant location

and NOT in a side branch.
