Systems and Methods for Percutaneous Spinal Fusion - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240008904 titled 'Systems and Methods for Percutaneous Spinal Fusion

Simplified Explanation

The patent application describes a system for percutaneous spinal fusion, which involves connecting two blades together to create a pathway from a skin incision to an implanted pedicle fastener. The blades are connected by a C-shaped coupling with flexible tabs that engage holes along the blades. If one blade becomes disconnected, a supplemental access device with a tubular body can receive the other blade. If both blades become disconnected, a supplemental access device with a gripping member and a locking member can prevent disengagement of the pedicle fastener.

  • The system includes two blades connected by a C-shaped coupling, creating a percutaneous pathway for spinal fusion.
  • The coupling has flexible tabs that engage holes along the blades, ensuring stability and alignment.
  • If one blade becomes disconnected, a supplemental access device with a tubular body can receive the other blade, maintaining the connection to the pedicle fastener.
  • If both blades become disconnected, a supplemental access device with a gripping member and a locking member prevents disengagement of the pedicle fastener.

Potential applications of this technology:

  • Spinal fusion surgeries, where the system can provide a percutaneous pathway for the insertion of pedicle fasteners.
  • Minimally invasive procedures, as the system allows for smaller incisions and reduced tissue disruption.

Problems solved by this technology:

  • Ensures stability and alignment during spinal fusion surgeries, reducing the risk of complications and improving surgical outcomes.
  • Provides a solution for cases where one or both blades become disconnected from the pedicle fastener, preventing the need for additional surgeries or interventions.

Benefits of this technology:

  • Minimally invasive approach reduces tissue damage, post-operative pain, and recovery time.
  • Improved stability and alignment during spinal fusion surgeries enhance the success rate and patient outcomes.
  • Supplemental access devices provide a backup solution in case of blade disconnection, ensuring the integrity of the pedicle fastener.


Original Abstract Submitted

a system for percutaneous spinal fusion may include two spaced apart blades connected together by a coupling such that the blades define a percutaneous pathway from a skin incision to an implanted pedicle fastener. the coupling may be c-shaped and may have at least one flexible tab for engaging one or more holes along the length of the blades. if one of the blades becomes disconnected from the pedicle fastener, a supplemental access device may be provided comprising a tubular body having a channel therein for receiving the other of the blades. if both of the blades become disconnected, a supplemental access device may be provided comprising a gripping member received within a locking member. the gripping member may have two legs engageable with the pedicle fastener, and the locking member may move along the gripping member to prevent the legs from disengaging the pedicle fastener.
