Intended Use
The LactoSorb® Sheets are used as fixation devices in the following procedures: A. General Indication: Trauma procedures of the midface or craniofacial skeleton. Specific Indications: 1. Comminuted fractures of the naso-ethmoidal infraorbital areas 2. Comminuted fractures of the frontal sinus wall 3. Pediatric midface or craniofacial trauma 4. Orbital floor fractures 5. Trauma of the craniofacial skeleton including: frontal, parietal, temporal, sphenoid, and occipital bones B. General Indication: Reconstructive procedures of the midface or craniofacial skeleton. Specific Indications: 1. Infant craniofacial surgery (i.e. craniosynostosis, congenital malformation, trauma, etc.) 2. Tumor reconstruction in midface or craniofacial procedures 3. Bone graft procedures in the midface or craniofacial skeleton 4. Pediatric reconstructive procedures 5. Reconstructive procedures of the craniofacial skeleton including: frontal, parietal, temporal, sphenoid, and occipital bones 6. Craniotomy flap fixation C. Mandible Indication: Used to maintain the position of bony fragments in mandibular bone graft procedures and are used in conjunction with rigid internal fixation.
Device Description
The LactoSorb® devices are made of bioresorbable and biocompatible polymers that have been used in surgical procedures for years. LactoSorb® resorbable copolymer is a synthetic polyester derived from lactic and glycolic acids. Polylactic/polyglycolic acid polymer degrades and resors IN VIVO by hydrolysis to lactic and glycolic acids, which are then metabolized by the body. The LactoSorb® material has been found to be biocompatible in both soft tissue and bone tissue. The material retains its strength for at least 8 weeks and completely resors by 9-15 months.

No
The description focuses on the material properties and intended use of a bioresorbable fixation device, with no mention of AI or ML technology.

No.
The device is described as a "fixation device" used to maintain the position of bony fragments and is not intended to treat or cure a disease or condition.

No

The information provided describes the LactoSorb® Sheets as "fixation devices" for "trauma procedures" and "reconstructive procedures," and the device description details its material composition and bioresorbable properties, all of which indicate a surgical implant, not a diagnostic tool.

No

The device description clearly states that the LactoSorb® devices are made of bioresorbable and biocompatible polymers, which are physical materials used as fixation devices. This indicates a hardware component, not a software-only device.

Based on the provided information, the LactoSorb® Sheets are not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • LactoSorb® Function: The LactoSorb® Sheets are described as "fixation devices" used in vivo (within the body) during surgical procedures to maintain the position of bone fragments. They are implanted directly into the patient.
  • Intended Use: The intended use clearly states their application in surgical procedures for trauma and reconstruction of the craniofacial skeleton and mandible. This is a structural and mechanical function within the body, not an analysis of bodily specimens.

Therefore, the LactoSorb® Sheets fall under the category of a surgical implant or fixation device, not an IVD.
