Polyurethane Carotid Shunts
Now Available!

Pruitt F3 the Next Generation Balloon Shunt
The Pruitt F3 Carotid Shunt is made with a new, more flexible material that is resistant to kinking, is color-coded for easy identification, and has 10% increased flow over the original Pruitt-Inahara Carotid Shunt.*

The Pruitt F3 Carotid Shunt is now available in a NEW 8F size.


Color Coding
The common inflation lumen and depth markings are now blue, to highlight the inflation path leading from the blue stopcock to the blue balloon.

Colored Safety Sleeve
The safety sleeve is tinted yellow to enhance visibilty and serves as visual que to promote the correct usage.

Depth Markings
Depth markings indicate the insertion length of the shunt for both the internal inflation lumen and external inflation lumen of the carotid shunt.

Both the Pruitt F3 and Pruitt-Inahara Carotid Shunt are secured in the vessel using occlusion balloons that eliminate the need for clamps. This reduces vessel trauma and allows for the use of a small incision, minimal dissection, and a short arteriotomy. Plaque endpoints can be visualized because the balloon holds the artery open during the procedure. This is especially important with high stenoses, when clamps cannot be used.

  • Eliminates the need for clamps.
  • Safety balloon with a moveable plastic sheath minimizes risk of internal carotid artery balloon over-inflation (pressure diverted to the safety balloon).
  • Blood flow and pressure monitoring can be performed through the T-port, along with infusion and flushing and removal of embolic particles.
Internal carotid balloon: made of latex, the balloon has an 8 mm diameter at maximum liquid capacity of 0.25 ml.

Common carotid balloon: has a 14 mm diameter at a maximum liquid capacity of 1.50 ml. Blue common carotid balloon corresponds to blue stopcock to simplify common carotid balloon inflation.

Safety balloon: if the internal carotid balloon over-inflates, the extra pressure is diverted to the safety balloon. 10-12 PSI is ideal for maintaining internal carotid balloon pressure; safety balloon inflates at 13-17 PSI.

Good Cerebral Perfusion: Dependable Flow Rates
A flow rate of 137.5 cc/min is adequate for one side of an average brain.† Flow rates for 9F model with blood pressure of 120/80 mm Hg.*:
  • Pruitt-Inahara outlying shunt: 180cc/min.
  • Inahara-Pruitt inlying shunt: 220cc/min.

FlexcelTM Carotid Shunt
LeMaitre offers straight shunt, the Flexcel Carotid Shunt.
Models & Specs

Flexibility: Soft, flexible polyurethane with atraumatic tips to minimize intimal trauma.

Increased Flow: Average flow is 39% - 104%* higher than leading competitors.

Improved Markings: Centimeter markings span the length of the shunt with a bar denoting center point for easier identification of placement in carotid artery.

Tether: Aids in removal of shunt.
