Intrinsic Therapeutics, Inc. has filed the Pre-Market Approval (PMA) application for the Barricaid® Anular Closure device. Barricaid is designed to help relieve sciatica pain in patients who undergo a discectomy for herniated discs.
According to Intrinsic Therapeutics, Barricaid is designed with multiple layers of counter-angulated fibers from a non-degrading polymer. These fibers create a flexible mesh.
“The layers mimic the structure of healthy anulus, which is itself formed from multiple layers of counter angled fibers of collagen, one of the body’s basic building blocks,” says Intrinsic Therapeutics. “Each layer of the Barricaid mesh is shaped to optimize flexibility while maximizing strength of the overall structure. The layers are sewn together and firmly secured to a strong titanium bone anchor that anchors the mesh to one of the surrounding vertebral bones.”
Manufacturers created Barricaid with titanium as is it can be used to anchor to bone. The anchor provides a foundation for the mesh so it says in place when pressure is applied to the mesh. The surface of the anchor is designed with a texture to help the bone grow onto the anchor.
“Today, quality patient care and the utilization of healthcare resources are scrutinized more than ever,” said Dr. Matthew McGirt, a Neurosurgeon at Carolina Neurosurgery & Spine Associates in Charlotte, North Carolina. “Technologies that demonstrate fewer repeat surgeries when compared to traditional treatment will fit into the paradigm of improving outcomes and conserving healthcare resources.”
