Indications for Use

The STARband and STARlight are intended for medical purposes for use on infants from 3 to 18 months of age, with moderate-to-severe non-synostotic positional plagiocephaly, including infants with plagiocephalic-, brachycephalic- and scaphocephalic-shaped heads by applying mild pressure to prominent regions of the infant's cranium in order to improve cranial symmetry and/or shape. The devices are also indicated for adjunctive use for infants from 3 to 18 months of age whose synostosis has been surgically corrected, but who still have moderate-to-severe cranial deformities including plagiocephalic-, brachycephalic- and scaphocephalic-shaped heads.

Device Story

STARband and STARlight are custom-fabricated cranial orthoses used to treat infant head deformities. The device applies mild pressure to prominent areas of the cranium while providing voids over depressed areas to redirect growth toward symmetry. Practitioners capture the infant's head shape using a plaster impression or 3D imaging (including the SmartSoc System). A positive model is created and modified to guide growth. The orthosis is worn ~23 hours/day. The device consists of a rigid outer shell (copolymer plastic, Surlyn, or Co-Polyester) and an optional inner foam liner (Pelite, Aliplast, or Reston). Designs include side-opening or bi-valve configurations secured with Velcro straps. The SmartSoc System uses a flexible fabric sock with a printed pattern and a consumer-grade digital camera with a non-coherent flash to capture 3D data. The device is prescribed by clinicians and managed by practitioners who adjust the interior as the infant's head grows. Benefits include improved cranial symmetry and proportion.

Clinical Evidence

Bench testing only. No clinical data. Performance was validated through repeatability and reproducibility (R&R) testing using uniform shapes representing pediatric patients, and a Cranial Shape Capture Accuracy Study comparing the SmartSoc System against traditional casting and predicate imaging methods across coordinate planes (A-P, M-L, P-D, radius parameters, squareness, and flatness).

Technological Characteristics

Custom-molded cranial orthosis. Materials: 5/32" copolymer plastic, 5/32"-1/4" Surlyn, 1/8"-7/32" Co-Polyester; liners include 1/2" Pelite or Aliplast foam. Sensing: 3D shape capture via SmartSoc System (fabric sock + consumer camera with non-coherent flash). Fabrication: 5-axis routing of positive mold. Biocompatibility: Cytotoxicity (Agar Diffusion), Closed Patch Sensitization, Primary Dermal Irritation.

Indications for Use

Indicated for infants 3-18 months old with moderate-to-severe non-synostotic positional plagiocephaly (plagiocephalic, brachycephalic, or scaphocephalic head shapes) to improve cranial symmetry/shape via mild pressure. Also indicated as adjunctive therapy for infants 3-18 months old with residual moderate-to-severe cranial deformities following surgical correction of synostosis.

#### IV. Description of Device/Modification

The STARband and STARlight redirects the head growth to improve proportion and symmetry. The practitioner takes a plaster impression or 3-dimensional captured image of the infant's head to acquire the existing shape. The mold is sealed and filled with plaster or the 3-dimensional image is carved from a rigid polyurethane foam blank to create a positive model of the head shape. The positive model is modified to obtain greater symmetry and space in the areas of flattening. The STARband and STARlight provide total contact over the prominent or bossed areas of the baby's head to discourage growth there. Over the course of treatment, the inside of the band is further modified by the practitioner to provide space for growth to occur in the flat or depressed areas. The shape of the STARband and STARlight directs growth into the areas of least resistance and creates a precise pathway for the head shape to improve in symmetry and proportion.

The STARband and STARlight product families as it was released in K140353 are essentially still the same devices. The STARband Side Opening design and STARband Bi-Valve design is made with an outer shell of 5/32" polyethylene-polypropylene copolymer plastic with an inner liner made of 1/2" pelite polyethylene foam or 1/2" Aliplast foam (closed cell polyethylene). The STARlight Side Opening design and the STARlight Bi-Valve design are made of a plastic shell of 5/32" - 1/4" clear Surlyn or 1/8" - 7/32" Clear Co-Polyester. The STARlight PRO (Post-operative Remolding Orthosis) design is made of 1/4" to 3/8" clear Surlyn. Optional Aliplast (closed cell polyethylene) padding is available for the clear plastic bands and in addition, optional Reston (polyurethane - 3M Medical Product) foam is available for the STARlight PRO design.

The STARband Side Opening design and the STARlight Side Opening design has a top opening and a side opening. The band is held in place by a Velcro® strap (1½' for STARband Side Opening and 1" for STARlight Side Opening) across the side opening. The STARlight PRO has two side openings, no top opening, and is held in place by a Velcro strap across each side opening. The STARlight Bi-Valve design and the STARband Bi-Valve design consist of two plastic shells that overlap with a superior sliding mechanism. The right and left overlap tabs are connected via a Velcro strap with chafe and loop.

The proposed device modification is the addition of a new 3-dimensional shape capture, specifically, the NetVirta SmartSoc™ System distributed by Orthomerica Products, Inc. This system uses a flexible fabric sock with a customized non-repetitive printed pattern and a consumer grade digital camera with it's a built-in flash light source. The built-in flash feature is a non-coherent (i.e. non-laser light) light source. Because this system

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

utilizes a consumer grade camera with a non-coherent light source for a flash, it is safe to use on infant patients under all circumstances.

#### V. Statement of Indications and Intended Use

### Statement of Indications:

The STARband and STARlight are intended for medical purposes for use on infants from 3 to 18 months of age, with moderate-to-severe non-synostotic positional plagiocephaly, including infants with plagiocephalic-, brachycephalic- and scaphocephalic-shaped heads by applying mild pressure to prominent regions of the infant's cranium in order to improve cranial symmetry and/or shape. The devices are also indicated for adjunctive use for infants from 3 to 18 months of age whose synostosis has been surgically corrected, but who still have moderate-to-severe cranial deformities including plagiocephalic-, brachycephalic- and scaphocephalic-shaped heads.

### Intended Use:

The STARband and STARlight are designed to treat infants with abnormal head shapes from age 3 to 18 months and is available by prescription only. Since growth is the driving factor in head shape correction, the infants wear the STARband or STARlight for approximately 23 hours per day. The most common head deformities are positional plagiocephaly, brachycephaly, and scaphocephaly. The STARband and STARlight have also been cleared to treat unresolved head deformities in patients who have undergone surgery to correct craniosynostosis. The same principles of cranial remolding apply to positional deformities and post-operative patients.

The STARband and STARlight Cranial Orthosis have already received FDA 510(k) clearance under K140353 for being manufactured from a 3-dimensional imaging device that utilizes a non-coherent light source and takes 2-dimensional (2D) images from triangulated positions for shape capture (3dMD Systems). The SmartSoc System also utilizes a non-coherent light source and takes 2D images from triangulated positions for shape capture. Considering that STARband and STARlight are still the same device as it was in the predicate device and that the shape capture devices have the same technological characteristics; the STARband and STARlight Cranial Othosis are substantially equivalent to the predicate device.

The STARband and STARlight are essentially the same Cranial Orthosis. The main difference between the STARband and STARlight are the materials used to produce them. The STARband and STARlight materials have been biocompatibility tested, and the results of the tests are listed below in Table 2.

#### Summary and Conclusions of Non-Clinical Performance Data VII.

The SmartSoc System was evaluated for safety and efficacy. The system uses a consumer grade camera and is safe to use on infants without any eye protection. The shape capture repeatability and reproducibility was evaluated and determined to be acceptable. An additional, Cranial Shape Capture Accuracy Study was performed concluding that the SmartSoc System yields a safe and effective product that is substantially equivalent to the predicate device.4 With sufficient accuracy and no concerns with the safety of the system, the SmartSoc System was determined safe and effective for capturing infant head shape data to manufacture the STARband and STARlight Cranial Orthosis.
