Title: John Sherman - Innovator in Spinal Implant Technology

Introduction

John Sherman is a notable inventor based in Wayzata, Minnesota, recognized for his contributions to spinal implant technology. With a total of two patents to his name, Sherman has made significant advancements in the field of biomaterials and prosthetics.

Latest Patents

Sherman's latest patents include a Multi-stage biomaterial injection system for spinal implants. This innovative method and apparatus fluidly couple a reservoir containing a flowable biomaterial to a mold. The flow of the biomaterial into the mold is controlled based on a first operating parameter, while at least one injection condition is monitored. The flow is further regulated according to a second operating parameter when certain injection conditions reach a threshold level. This system ensures that the second operating parameter is maintained during the curing process of the biomaterial. In some embodiments, it allows for a portion of the biomaterial to be expelled from the mold.

Another significant patent is the Rail-based modular disc nucleus prosthesis. This invention provides a method and apparatus for repairing a damaged intervertebral disc nucleus in a minimally invasive manner. It utilizes a modular disc prosthesis comprised of at least three modular segments and two rails that connect adjacent segments. Each modular segment features a harder inner portion and a softer outer portion, allowing for flexibility and durability. The rails facilitate the interlocking of segments, and a removable stem portion ensures that the implanted device closely mimics the geometry of the disc nucleus cavity.
