A new, simple, atraumatic device for clampless vascular surgery
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™ is a polymer-based device which is comprised of a nontoxic and biocompatible gel that exists as a liquid at low temperatures and rapidly transitions to a solid at body temperature, forming a plug that can occlude blood vessels. LeGoo™ is injected into a blood vessel that is intended to be occluded, where it stays in a “plug” form for several minutes allowing the surgeon to work in a bloodless field. The gel dissolves with time (spontaneously) or can be reversed back to liquid instantly by cooling the site with ice or irrigating with cold saline. Once dissolved below a minimum concentration, the polymer can never re-solidify.
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.
LeGoo™ is manufactured by Pluromed and is fully CE approved
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
