Intended Use
The STARband is intended for medical purposes for use on infants from three to 18 months of age, with moderate to severe non-synostotic positional plagiocephaly, 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 device is also indicated for adjunctive use for infants from three to eighteen months of age whose synostosis has been surgically corrected, but who will have moderate to severe cranial deformities including plagiocephalic-, brachycephalic-, and scaphocephalic- shaped heads.
Device Description
The STARband® 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 3dimensional 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® provides 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® 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® Side Opening design and STARband® Bi-Valve design are 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 STARband® 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) across the side opening. The STARband® Bi-Valve design consists 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 STARband® Plus cranial orthosis device proposed in this submission has identical indications for use to the predicate submission K082950. The difference with this proposed device is a structural change to a dual side opening design with a living hinge at the top. The indications for use, the intended use, and the underlying principles of operation of the STARband® cranial orthosis remain exactly the same.

No
The description focuses on the physical design and modification process of the cranial orthosis, with no mention of AI or ML for analysis, design, or treatment planning. The 3D imaging is used for creating a physical model, not for AI/ML processing.

Yes.
Explanation: The device is intended for medical purposes to correct cranial deformities in infants by applying mild pressure and redirecting head growth to improve symmetry and/or shape. This aligns with the definition of a therapeutic device which aims to treat or correct a medical condition.

No

The provided text clearly states that the STARband is intended for "improving cranial symmetry and/or shape" by applying mild pressure to the infant's cranium, and for redirecting head growth, rather than for diagnosing conditions. It describes a treatment device.

No

The device description clearly details a physical cranial orthosis made of plastic and foam, with Velcro straps and a living hinge. It is a tangible medical device, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • STARband Function: The STARband is a physical device (a cranial orthosis) that is worn externally on an infant's head. Its purpose is to physically reshape the skull by applying pressure.
  • Lack of Biological Sample Analysis: The device description and intended use clearly indicate that the STARband does not analyze any biological samples from the infant. It works by physically interacting with the external structure of the head.

Therefore, the STARband falls under the category of a medical device, but not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

For the STARband Plus non-clinical performance test, it is assumed the cranial remolding orthosis is donned and doffed roughly 4 times a day for 6 months. The goal is to introduce localized fatigue at the living hinge by applying a repeated stress for 1440 cycles. Once the part has achieved 1440 cycles or fatigue life, whichever is reached first, the helmet will be removed from the machine/fixture and all materials located at the hinge (both plastic and foam), will be visually assessed for signs of wear or failure (fracture or yield). The success criteria for this test is determined by the living hinge achieving, or exceeding, 1440 cycles without experiencing failure.

All STARband Plus configurations (1/2" Aliplast, (4) 1/8" Aliplast, and ½" Pelite) successfully completed 1440 cycles without fatigue/failure impacting the living hinge. The sample population included both deformational and post-operative patients. STARband Plus living hinge design exceeded the normal application life cycle. The helmet durability across all liner types is verified at confidence level to structurally withstand the donning/doffing process throughout a 6-month treatment.

IV. Description of Device/Modification

The STARband® 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 3dimensional 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® provides 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® 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® Side Opening design and STARband® Bi-Valve design are 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 STARband® 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) across the side opening. The STARband® Bi-Valve design consists 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 STARband® Plus cranial orthosis device proposed in this submission has identical indications for use to the predicate submission K082950. The difference with this proposed device is a structural change to a dual side opening design with a living hinge at the top. The indications for use, the intended use, and the underlying principles of operation of the STARband® cranial orthosis remain exactly the same.

V. Indications for Use and Intended Use

Indications for Use:

The STARband® is intended for medical purposes for use on infants from three 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 device is also indicated for adjunctive use for infants from three to eighteen months of age whose synostosis has been surgically corrected, but who will have moderate to severe cranial deformities including plagiocephalic-, brachycephalic-, and scaphocephalic- shaped heads.

5

Intended Use:

The STARband® is 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® for approximately 23 hours per day. The most common head deformities are positional plagiocephaly, brachycephaly, and scaphocephaly. The STARband® has 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.

Summary of Non-Clinical Performance Data VIII.

For the STARband Plus non-clinical performance test, it is assumed the cranial remolding orthosis is donned and doffed roughly 4 times a day for 6 months. The goal is to introduce localized fatigue at the living hinge by applying a repeated stress for 1440 cycles. Once the part has achieved 1440 cycles or fatigue life, whichever is reached first, the helmet will be removed from the machine/fixture and all materials located at the hinge (both plastic and foam), will be visually assessed for signs of wear or failure (fracture or yield). The success criteria for this test is determined by the living hinge achieving, or exceeding, 1440 cycles without experiencing failure.

All STARband Plus configurations (1/2" Aliplast, (4) 1/8" Aliplast, and ½" Pelite) successfully completed 1440 cycles without fatigue/failure impacting the living hinge. The sample population included both deformational and post-operative patients. STARband Plus living hinge design exceeded the normal application life cycle. The helmet durability across all liner types is verified at confidence level to structurally withstand the donning/doffing process throughout a 6-month treatment.

IX. Conclusion

The STARband® Plus cranial orthosis device proposed in this submission is substantially equivalent given that it has the same indications for use, intended use, and underlying principles of operation to the predicate submission K082950.
