Use of CADISS Medical Device to Facilitate Dissection of Epidural Fibrosis in Revision Spine Surgery

Not Applicable
Completed
Conditions
Spine Surgery
Interventions
Device: CADISS
Registration Number
NCT05016739
Lead Sponsor
AuXin Surgery SA
Brief Summary

The CADISS® System, Chemically Assisted mechanical DISSection, is intended for the selective detachment of pathological tissue layers and/or fibrotic tissues in various surgical procedures without using cutting instruments. It is based on the property of the drug mesna (Sodium 2-mercaptoethane sulfonate) to cleave the disulfide bonds responsible for the adherence of pathological tissues and for the strength of fibrosis. Revision spine surgery is more difficult than primary surgery because of the development of fibrosis and scar tissues since the first operation. Fibrosis may develop in the spinal canal and will adhere strongly to the dura mater and to the nerve roots. This study is a prospective, multi-sites, open label, single cohort clinical trial evaluating the use of CADISS medical devices to facilitate dissection of epidural fibrosis in patients who undergo a revision in spine surgery after at least one year.
