First in Louisiana to Offer New Artery Clearing Device

An innovative device, called the Jetstream® System, is giving patients who suffer from peripheral arterial disease (PAD) an improved, non-surgical treatment option to restore blood flow in arteries that have become clogged and hardened due to a build-up of plaque.  The procedure, called atherectomy, has been around for several years, but the Jetstream offers significant benefits over previous catheterization devices.

“Atherectomy is a fairly common procedure, where a catheter is guided into an artery in the leg, and then used to cut through the blockage caused by plaque build-up,” says Dr. Charles Mayes, Jr., cardiologist.  “The devices that came to market earlier had some issues that Jetstream was able to overcome.  First, previous catheters created debris that could ‘float downstream’ and lodge in smaller vessels or form a clot.  Jetstream includes an aspiration device—or vacuum—that sucks this debris into the catheter and removes it from the body.”

Additionally, “Jetstream is adjustable to the size of the artery, which allows one catheter to be used throughout the procedure as the artery widens or narrows.  This cuts the procedure time down from about 45 minutes to as fast as four minutes.  Most importantly, Jetstream actually removes plaque and calcium build-up safely with less chance of damaging the artery itself.”

PAD, also known as peripheral vascular disease, is estimated to affect 12 million Americans.  The most telltale symptom of the disease is severe leg pain while walking or during mild exercise, which goes away when the activity stops.  For Lafayette resident, Peggy Hebert, the pain was interfering with her daily activities.

“I live about two acres from the mailbox.  On the walk back to the house, my right leg would become so painful, the trip would be a struggle.  I ignored it at first thinking it was varicose veins,” says Hebert.  “Now (after the procedure) I have no problem with the walk; it’s made a huge difference.  In fact, my right leg hurt so much that I only noticed the pain in that leg.  Now I can really feel it in the left, and would like to get that one done as well.”

Other signs of PAD are foot or toe pain at rest that often disturbs sleep, skin wounds or ulcers on feet or toes that are slow to heal, and weakness in legs.

“Peripheral arterial disease is not to be taken lightly, because if the disease progresses it can lead to critical limb ischemia, when patients experience leg pain even while resting, sores that do not heal, and gangrene, which can lead to amputation,” says Dr. Mayes.  “People who suffer from PAD are much more likely to have plaque build-up in arteries of the heart and brain, leading to a higher risk of stroke and heart attack.”

The Jetstream® Revascularization System is the first on the market capable of treating an entire spectrum of disease found in the PAD patient, including hard and soft plaque, calcium, thrombus and fibrotic lesions with consistent clinical results. The Jetstream catheter is equipped with tiny rotating blades and a vacuum that cuts through accumulated plaque in the legs and then vacuums away the debris left behind.

Dr. Charles Mayes, Dr. Mark Campbell and Dr. Christopher LaGraize perform the Jetstream procedure in the catheterization lab at Lafayette General; patients are typically released that same day and instructed to stay off the leg for 24 hours.

About Jetstream G2
Jetstream G2 consists of a sterile, single-use catheter and control pod and a reusable, compact console that mounts to a standard I.V. stand. The catheter has an expandable cutting tip that safely debulks and preemptively removes both hard and soft plaque, as well as calcium, thrombus and fibrotic lesions. A highly efficient aspiration port located just proximal to the cutting blades continually removes excised tissue and thrombus from the treatment site to a collection bag located on the console. A fully recessed masticating system within the aspiration port helps break aspirated material into smaller pieces before removal, providing significant benefits for the treating physician and patient while ensuring no contact with the artery walls. The distal portion of the catheter also possesses infusion ports that provide continuous infusion of sterile saline during the atherectomy procedure. Active aspiration is a safety feature that minimizes the risk of distal embolization.

With simple set up and an ergonomic design for easy operation by trained clinicians, Jetstream G2 maximizes treatment effectiveness. Jetstream G2 offers renewed hope for non-surgical candidates and the benefits of a minimally invasive treatment option, including faster recovery and decreased systemic complications.
