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.

Interventions

Type	Name	Description
DEVICE	CADISS	The CADISS® device was procured from AuXin Surgery. It consists in three elements: 1. A single use disposable Remote Kit, containing a sterile cartridge, which prepares the Drug Product immediately before use, and the sterile tubing for fluid connexion. The Drug Product is a 30 ml sterile 5% mesna solution of pH 7.3+/-0.5 2. Reusable stainless steel non-cutting mechanical instruments similar to those used in the normal practice, except for the provision of an internal irrigation channel bringing the Drug Product at the working edge. 3. A pedal controlled electric motor driving the peristaltic cassette included in the disposable tubing in order to control the dispensing of the Drug Product during the procedure.
