AI Summary extracted from FDA summary PDF · never regenerated
Intended use

Oxiplex is a synthetic, absorbable gel made of sodium carboxymethylcellulose and polyethylene oxide, supplied sterile in a pre-filled syringe with an applicator. It is applied to nerve roots and adjacent tissues during lumbar spine surgery to reduce leg pain and neurological symptoms in adult patients undergoing discectomy.

Technological characteristics

The subject device is a 1.5 mL configuration of Oxiplex, compared to the predicate's 3 mL configuration. Both share identical intended use, type of use, anatomic location, implanted material, mechanism of action, syringe materials, applicator material, and sterile packaging. The only difference is individual volume.

Test standards cited

Not stated in this summary.

Substantial equivalence argument

The 1.5 mL configuration is substantially equivalent to the 3 mL predicate device because the change involves only volume without altering material formulation, processing, mechanism of action, or tissue contact. Clinical data from the predicate device study included a subset analysis comparing subjects who received 1.5 mL or less of gel, demonstrating that this lower volume does not raise different questions of safety or effectiveness.
