Publication number: 20200187957Abstract: A method and device for reducing the damaging effects of radiant energy, blast, or concussive events includes applying pressure to at least one jugular vein to reduce the egress of blood from the cranial cavity during or before the incidence of the imparting event. Reducing blood outflow from the cranial cavity increases intracranial volume and/or pressure of the cerebrospinal fluid to reduce the risk of traumatic brain injury and injuries to the spinal column. Reducing blood outflow further increases the intracranial pressure and volume, and thereby increases the pressure and volume of the cochlear fluid, the vitreous humor and the cerebrospinal fluid to thereby reduce the risk of injury to the inner ear, internal structure of the eye and of the spinal column. In addition, increasing intracranial pressure and volume reduces the likelihood of brain injury and any associated loss of olfactory function.Type: ApplicationFiled: November 13, 2019Publication date: June 18, 2020Inventors: David W.

Publication number: 20200187996Abstract: A plating system is described that uses various configurations of bone fixation implants that are configured to be attached to one or more portions of bone. The bone fixation implant may include at least one structural portion (e.g., a wire, plate, mesh, etc.) that includes metal and a polymer body at least partially surrounding the at least one structural portion. The polymer body may define an engaging surface that is configured to engage an attachment member that is applied to the bone fixation implant to fix the bone fixation implant to the bone, such that direct contact between the metal of the structural portion and the attachment member is prevented. Overlying muscle and tissue may be secured to the bone fixation implant to encourage incorporation of the tissue structure into the implant and promote stabilization and healing.Type: ApplicationFiled: August 10, 2018Publication date: June 18, 2020Inventor: Jeko Metodiev Madjarov
