The Cobra Fusion™ is connected to the Electrosurgical Unit (ESU) by a cable permanently attached to the
handle of the Probe. Directions for use of the ESU may be found in the ESU Operator’s Manual.
The distal ablation Probe includes an integrated vacuum stabilizer, which is connected to a vacuum source
using the included accessory tubing. Accessory tubing consists of a 3-way stopcock and tubing with a male
luer connector on one end and vacuum source connector on opposite end. The stopcock/tubing attaches to
the tubing that exits the Probe handle. A three foot segment of tubing for connecting a fluid canister to a
vacuum source is also provided.
The Cobra Fusion™ comprises a magnet at its distal end which couples to the magnetic connector at the
proximal end of the Introducer. This allows the user to temporarily attach the Introducer, guide the Probe to
the desired anatomical position, and then decouple the Introducer. The Cobra Fusion™ Introducer can be
used as needed to advance the Probe to the desired anatomical position. The Introducer has a curved
shape that is straightened out with an inserted stainless steel stylet for initial use. After the straightened
distal end of the Introducer is advanced to the desired location of the heart, the stylet is removed while the
Introducer is advanced. The proximal magnetic connector of the Introducer is then attached to the distal
magnetic connector of the Cobra Fusion™ Probe. The distal end of the introducer can be retrieved by using
either the ball-tipped retriever or the flexible retriever provided in the accessory retriever kit. Once coupled,
pulling on the Introducer/Retriever will bring the Probe into alignment with the target tissue. Once in place,
the Introducer is detached from the ablation Probe.
When the Cobra Fusion™ is connected to an auxiliary temporary external pacemaker it can be used to
provide transient cardiac pacing, sensing, recording, and stimulation for the assessment of electrical
isolation / conduction block of ablation lesions in the surgical treatment of arrhythmias. The COBRA Fusion
must be disconnected from the ESU and connected to a temporary external pacemaker using the accessory
cable provided.
