Indications for Use

The DOC Band 3D (band) is a medical device known generically as a cranial orthosis. A cranial orthosis is used to treat a medical condition known as deformational plagiocephaly brachycephaly (DPB).

Device Story

DOC Band 3D is a custom-fitted cranial orthosis for infants 3-18 months. Device applies mild holding pressure to prominent cranial regions while encouraging growth in adjacent flattened areas to improve symmetry and shape. Used during period of rapid brain growth. Clinician custom-fits device to patient; adjustments made as needed throughout treatment. Device consists of 3D-printed semi-rigid polyamide outer shell and lightweight polyethylene foam inner layer. Replaces vacuum-formed shell of predicate devices with 3D-printed shell for increased precision and customization. Benefits patient by correcting cranial deformities through controlled pressure.

Clinical Evidence

Bench testing only. Mechanical properties (shear, flexural, stiffness, fatigue, bond strength) compared to predicates; results meet or exceed predicate performance. Biocompatibility testing (cytotoxicity, irritation, sensitization) performed on polyamide 12 resin per ISO 10993, passing all tests. Clinical performance expected to be comparable to predicates.

Technological Characteristics

Cranial orthosis; semi-rigid polyamide 12 resin outer shell (3D printed); lightweight polyethylene foam inner layer. Custom-fit to patient anatomy. Mechanical properties tested for shear, flexural, stiffness, fatigue, and bond strength. Biocompatible per ISO 10993.

Indications for Use

Indicated for infants 3-18 months with moderate to severe non-synostotic cranial deformation (plagiocephalic, brachycephalic, scaphocephalic, or combinations). Also indicated for adjunctive use in infants 3-18 months post-surgical correction of synostosis with residual moderate to severe cranial deformities. Contraindicated for infants with craniosynostosis or hydrocephalus.

Regulatory Classification

Identification

Trade Name: DOC Band 3D

Common Name: Cranial Orthosis

Device Classification: Class II

Product Code: OAN

Requlation Number: 21 CFR 882.5970

Device Description: The DOC Band 3D is a cranial orthosis intended to treat positional plagiocephaly in infants from 3 to 18 months of age. The band is intended to apply a mild pressure to the prominent regions of an infant's cranium and to improve cranial symmetry, proportion, and/or shape.

Theory of Operation: The DOC Band 3D works by applying a mild holding pressure in regions where the head is already too prominent, while encouraging growth in the adjacent flattened regions. In this manner, the band is used to treat not only craniofacial asymmetry, but also proportionality (length to width ratio) of the head. The band is used from three to eighteen months of age because this is the period of rapid brain growth. After two years of age, skull growth stops, and any remaining growth of the cranium is primarily from thickening and hardening of the cranial bones,

Predicate Device(s):

- DOC Band® (K964992) .
- DOC Band (K141012) .
- DOC Band PostOp™ (K042385) .

Substantial Equivalence: The DOC Band 3D is substantially equivalent to the predicate devices. The primary difference is the manufacturing process: the DOC Band 3D utilizes 3D printing technology to fabricate the outer shell, while the predicate devices used vacuum forming. This change allows for greater precision and customization without affecting the device's intended use, safety, or effectiveness.

{5}------------------------------------------------

Intended Use: The DOC Band 3D (band) is a medical device known generically as a cranial orthosis. A cranial orthosis is used to treat a medical condition known as deformational plagiocephaly brachycephaly (DPB).

Indications for Use: The DOC Band is indicated for use on infants from three to eighteen months of age with moderate to severe non-synostotic cranial deformation, including infants with plagiocephalic-, brachycephalic-, and scaphocephalic-shaped heads, or a combination thereof.

The DOC Band 3D is also indicated for adjunctive use for infants from three to eighteen months of age whose synostosis has been surgically corrected, but who still have moderate to severe cranial deformities including plagiocephalic-, brachycephalic-, and scaphocephalic/dolicocephalic- shaped heads, or a combination thereof.

Contraindications for Use: The DOC Band 3D is contraindicated for use on infants with craniosynostosis or hydrocephalus.

Summary of Safety and Effectiveness: The DOC Band 3D is made from biocompatible materials that have undergone ISO 10993 testing to ensure safety. Bench testing has demonstrated that the device's mechanical properties meet or exceed those of the predicate devices. The clinical performance of the DOC Band 3D is expected to be comparable to the predicate devices in the treatment of deformational plagiocephaly.

Comparison of DOC Band 3D to Predicate Devices

{6}------------------------------------------------

{7}------------------------------------------------

Test Summary of Non-Clinical Data

To ensure substantial equivalence of their mechanical forces, the predicate DOC Band and proposed DOC Band 3D both underwent mechanical testing of their shear, flexural, stiffness, fatigue and bond strength. Senior clinicians evaluated the proposed device against the predicate device to confirm equivalent donning and doffing procedures, trims and adjustment procedures, demonstrating substantial equivalence in the fit and treatment protocols. The new material in the proposed device (as compared to the predicate) is the outer shell. It is a polyamide 12 resin, which was tested per ISO 10993 for cytotoxicity, irritation and sensitization, passing all tests per standards.

Conclusion: The DOC Band 3D is substantially equivalent to the predicate device.
