Intended Use

The NMX-1000™ is designed to surgically remove a strip of the Trabecular meshwork for surgical management of infantile and adult glaucoma.

Device Story

NMX-1000™ is a sterile, single-use bipolar electrosurgical probe; used for surgical management of infantile and adult glaucoma. Device features bipolar probe tip, irrigation channels, and aspiration channels; handpiece constructed of ABS plastic with stainless steel probe. Operates by connecting to a compatible electrosurgical generator; delivers low-energy radio frequency current to the probe tip to cut/remove a strip of trabecular meshwork. Used by surgeons in clinical settings; provides irrigation and aspiration capabilities similar to standard goniotomy knife cannulas. Benefits include precise tissue removal for glaucoma management.

Clinical Evidence

Bench testing only. Biological safety of patient-contact materials demonstrated per standards. Electrical safety verified via compliance with IEC 60601-1 (leakage current, dielectric voltage) and ANSI/AAMI HF-18. Device integrity, tip bend resistance, and sterility (SAL 10^-6) confirmed through bench testing.

Technological Characteristics

Bipolar electrosurgical probe; ABS plastic handpiece; stainless steel probe tip. Energy source: external compatible electrosurgical generator. Connectivity: connects to standard irrigation/aspiration devices. Sterilization: sterile, single-use. Compliance: IEC 60601-1, ANSI/AAMI HF-18.

Indications for Use

Indicated for surgical management of infantile and adult glaucoma by removing a strip of the trabecular meshwork.

Regulatory Classification
