An Evolution of Spinal Fusion for Aging Instability
Minuteman® G6 is the next evolution of the Minuteman family—engineered for tissue-sparing, direct-access stabilization of aging instability.
Built on the proven Minuteman platform, G6 refines how physicians lift, balance, realign, and secure the lumbar segment through a simplified surgical workflow and enhanced instrumentation.
The Problem Minuteman Solves
Many patients suffer from aging instability. Typical symptoms can include:
-
- Worsened pain with loading (standing, walking, extension, and transitions such as sit-to-stand or bending)
- Improved symptoms with unloading (sitting, flexion)
These patterns drive claudication, mechanical back pain, and radicular symptoms—often visible only on flexion–extension imaging. Durable relief requires more than decompression—it requires stabilization.
Minuteman® G6 is designed to:
-
- Lift: Doubles foraminal area
- Balance: ~3x increase in posterior disc height
- Reduce: Reduces motion by 82%
- Secure: 93% fusion rate
Innovative Design Enhancements
-
- Fluoroscopic Depth-Reference Marker on the Implant Body: A bold midline reference engineered to provide a cue for controlled advancement and a natural stopping point
- Single-Knob Inserter with Integrated Torque-limiting Control: Streamlined instrumentation with tactile feedback and a built-in torque limiter designed to restrict over-advancement and overtightening.
- Minimally Disruptive Tissue Retractor Profile: An access corridor intended to minimize tissue disruption while maintaining procedure control.
- Bilateral Wing Deployment (Ipsilateral and Contralateral): Controlled deployment on both sides of the implant for segmental engagement and stabilization.
- SimpliFuse™ Coating: Features a nano-structured hydroxyapatite coating approximately 1,000× smaller than conventional Hydroxyapatite, designed to promote earlier bone on-growth and fusion response.
Design Philosophy
The Minuteman® technology consists of thoughtfully-designed instrumentation and implants that enable providers to perform all of the necessary elements to achieve fusion of the posterior bony elements of the lumbar spine.
The tissue-sparing approach uses a series of instruments to access and enable direct visualization of the posterior bony elements (e.g., posterior bony anatomy, laminae, facet joints, etc.) and to decorticate bony surfaces using two specialized decortication instruments. Next, bone graft materials are placed in the implant and delivered directly in contact with the freshly decorticated bone. The implant is placed under compression between the bony surfaces to encourage osseointegration and is then locked in place to span the interspace with secure fixation points at each end of the construct.
SimpliFuse™ Surface Technology
Minuteman® G6 incorporates SimpliFuse™ nano-scale surface technology, all without altering the minimally-invasive procedural profile:
-
- Enhances implant-to-bone contact
- Supports early cellular attachment
- Optimizes the fusion environment

Physician Perspective
“Minuteman G6 reflects a thoughtful progression—supporting stabilization through a minimally invasive, tissue-sparing, direct access approach. This is exactly the type of advancement we need in interventional spine.”

Indications for Use
The Minuteman® G6 Fusion Plate is a posterior, non-pedicle fusion device, intended for use at a single interspace in the non-cervical spine (L1-S1). It is intended for plate fixation/attachment to spinous processes for the purpose of achieving instrumented posterior arthrodesis (i.e., fusion) in the following conditions:
-
- Lumbar Spinal Stenosis;
- Degenerative Disc Disease (DDD) (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); and/or
- Spondylolisthesis.
The Minuteman® G6 MIS Fusion Plate is intended for use with bone graft material. The device may be implanted via a lateral transverse approach (L1-S1).
