US-based Kleiner Device Labs has introduced a new spinal bone graft delivery tool for use in less-invasive procedures.
The patented KG 1 graft delivery tool features a cannula, plunger and detachable funnel, which enable easy loading of graft material.
Kleiner’s new tool will reduce the costs of spinal fusion surgery for hospitals and payers, as well as provides less post-operative pain and infection risk for patients and facilitates less-invasive procedures for surgeons.
The delivery tool’s shape is said to allow easier entry into the disk interspace, helping to minimize soft tissue damage or irritation.
Kleiner has developed bi-portal design for the tool to release graft material for filling both sides of the disk space, while leaving a central void for insertion of a fusion cage.
The KG 1, which is disposable and made of Lexan, avoids the system costs of cleaning and restocking.
Kleiner Device Labs founder and CEO Jeff Kleiner said: "In my own surgical practice, I was frustrated by unacceptable failure rates in spinal fusions and bad outcomes for my patients that were driven by existing graft delivery tools that jam, don't distribute graft material to the right locations or quantity, or required excessive manipulation that creates soft tissue inflammation or damage.
"In testing, we found that the KG 1's design solves all these problems, and use of the new tool, alone, improved my spinal arthrodesis rate from 75% to 92%.”
Based in Incline Village of California, Kleiner Device Labs is engaged in the development of new tools and devices for minimally invasive spine surgery.
