The telemetry probe and insertion of the probe during telemetry surgery

(A) Telemetry probe. The probe body contains a battery, signal emitter and sensor. The catheter is filled with a non-compressible fluid and bio-compatible gel at the catheter tip. The tip is coated with an anti-thrombogenic film.

(B) Implantation procedure. Blood flow in the descending (abdominal) aorta is briefly occluded and a small incision is made in the arterial wall. A catheter introducer with a grooved tip is used to lift a flap at the incision site. The catheter is introduced using forceps and is guided into the vessel through a groove in the catheter introducer. Once the catheter was in place and an adequate signal is detected, the catheter is secured in place with glue and a cellulose patch.
