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

• Uniquely self-forms to fit any vessel, regardless of the degree of atherosclerosis or calcification
  
  
• No radial pressure (unlike clamps, loops or balloons) to prevent intimal damage to the vessel
  
  
• Prevents back bleeding from side-branches and collaterals to create a bloodless surgical field
  
  
• Transparent to improve visualization during vascular procedures
  
  
• Does not need to be removed before completion of an anastomosis
  
  
• Can be sewn through and dissolved at will
