Intended Use

DemeSTEEL is a stainless steel suture composed of 316L stainless steel, with or without needles attached, and is intended for use in abdominal wound closure, intestinal anastomosis, hernia repair, sternal closure and certain orthopedic procedures, including cerclage and tendon repair.

Device Story

DemeSTEEL is a sterile, non-absorbable surgical suture composed of 316L stainless steel; available as monofilament or multifilament thread; supplied with or without attached needles. Used by surgeons in clinical settings for tissue approximation in abdominal, intestinal, hernia, sternal, and orthopedic procedures. Device provides mechanical support for wound healing; maintains tensile strength; does not degrade in vivo. Benefits include biocompatibility and high tensile strength for demanding surgical closures. Device is single-use.

Clinical Evidence

No clinical trials were conducted or required. Substantial equivalence is supported by bench testing confirming conformance to USP 36 standards for diameter, length, tensile strength, and needle attachment, as well as ISO 11137 sterility requirements and biocompatibility testing (cytotoxicity, acute toxicity, skin sensitization, mutagenicity, carcinogenicity, and reproductive toxicity).

Technological Characteristics

Material: 316L stainless steel per ASTM F138 Grade 2. Form: Monofilament or multifilament thread, with or without needles. Sterilization: Gamma irradiation. Performance: Meets USP 36 requirements for non-absorbable sutures, including tensile strength, diameter, and needle attachment. Connectivity: None. Software: None.

Indications for Use

Indicated for abdominal wound closure, intestinal anastomosis, hernia repair, sternal closure, and orthopedic procedures including cerclage and tendon repair.

Regulatory Classification

Identification
