LeGoo® Internal Vessel Occluder

A new, simple, device for clampless vascular and cardiovascular surgery

For years surgeons have been looking for a simpler, atraumatic method to control bleeding during surgery. Ideally, this method would also prevent back-bleeding from side branches and collaterals — and not require removal before completion of the anastomosis.

LeGoo® is a water-soluble, low-viscosity gel. It forms a gel plug at body temperature and conforms to any vascular geometry. LeGoo® temporarily stents the vessel to facilitate constructing the anastomosis and allows for suturing directly through the gel. LeGoo® does not need to be removed before completing the anastomosis. Upon completion, LeGoo® is dissolved by applying ice directly to the vessel.

LeGoo’s ability to revert to a liquid state is a function of both temperature and concentration. Therefore, the diluted material will not re-gel once it is dissolved: it passes through the microcirculation and is excreted in urine.

Clinical Benefits

• No radial pressure (unlike clamps, loops, or balloons)
• Enables surgery on diseased vessels
• Provides a better bloodfree field
• Enables shorter time of occlusion and anastomosis
• Minimizes dissection
• Stents vessel for easier suturing
• Blood flow can be restored at will
