InVivo Therapeutics Holdings Corp., formerly Design Source, Inc. is a development-stage company. The Company is developing and commercializing technologies for the treatment of spinal cord injuries. The Company develops biopolymer scaffolding devices for the treatment of spinal cord injuries. The biopolymer devices are designed to protect the damaged spinal cord from further secondary injury and promote neuroplasticity, a process where functional recovery can occur through the rerouting of signalling pathways to the spared healthy tissue. The Company�s biopolymer-based devices are surgically implanted or injected into the lesion created during traumatic injury, or the primary injury. The Company�s porous biopolymer scaffold consists of polylactic-co-glycolic acid (PLGA) and-polylysine. The Company focuses to develop an injectable hydrogel designed to counteract the inflammatory environment.
