Dynamic Spinal Tethering System

A flexible tether to correct scoliosis

The Problem

Scoliosis affects roughly 15 million children in the U.S. Bracing has problem to slow down scoliosis progression in some patients, but usually does not prove to be successful at correction. 

The Solution

Auctus Surgical, Inc. is developing a flexible tether that is affixed surgically via bone screws in a non-fusion procedure to constrain future growth on one side of the spine. The device is screwed on the lateral side of each vertebra on the convex side of the scoliotic spine. As the child grows, the non-constrained side of the spine gradually "catches up" to the tethered side to straighten the spine. Further, the tether is anchored to a magnetically actuated spool, which allows for additional non-surgical tensioning or releasing of the tether over time via an exteral controller--a form of an internal brace.

Under Development

In November 2017, the team was awarded $50,000 through the UCSF PDC Accelerator. Since then, the team has completed a prototype and testing on a cadavaric spine. They are collaborating with surgeons at Shriner's Hospital for Children - Philadelphia
