Nexus Spine introduced PressON, a patient-specific fixation system for stabilizing the human spine, and Tranquil, a flexible titanium device for interbody fusion.
The devices feature novel application of compliant mechanism technology, allowing biocompatible materials like titanium to behave as organic human tissue, on a microscopic level. This enables well-performing bio-friendly synthetic materials to perform more like surgically treated tissues. Since 2015, Nexus has implanted the devices in hundreds of patients and has found faster healing and with less pain.
Through compliant mechanism-based compositions and 3D printing, Nexus Spine's Tranquil device is the only technology to obtain the optimal combination of stiffness and porosity for the spine to encourage rapid spinal bone growth, resulting in faster healing and less pain.
The interbody device is shaped and engineered to act just like spinal bone, with the same stiffness as human spinal trabecular bone.
Tranquil eliminates measurable subsidence to substantially improve clinical outcomes in patients, including those who are the least likely to typically experience healthy bone growth.
A primary cost saver attributed to use of Tranquil is the elimination of supplemental biologics to stimulate bone growth. Post-operative data from hundreds of Tranquil patients indicates that healing time, as defined by spinal stability, is months faster.
PressON is a patient-specific spinal fixation system designed to eliminate stresses caused by other systems.
PressON employs compliant-mechanism technology to match the patient's specific needs, eliminating spinal rod-bending and other persuasion techniques currently used in spinal surgeries. PressON can exactly match the shape of the most complex spinal surgeries. Further, PressON can be installed in 1/16 the amount of time. It is one-third the volume of other predicate devices, minimizing soft tissue irritation and decreasing the incision to half the length.
Through the use of modern mathematical modeling, 3D finite element analysis, and 3D printing, Nexus seeks to improve the way that spinal implants perform.
