Indications for Use

The Infrascanner is indicated for the detection of traumatic supratentorial hematomas of as small as 3.5mL and as deep as 2.5 cm from brain surface, but not both at the same time, as an adjunctive device to the clinical evaluation in the acute hospital setting of adult patients and pediatric patients aged 2 years and older with suspected traumatic supratentorial intracranial hematoma. The device is indicated to assess patients for CT scans but should not serve as a subsitute for these scans, the device should only be used to rule in subjects for the presence of hematoma, never to rule out. The Infrascanner is indicated for use by Physicians, or under the direction of a physician, who has been trained in the use of the device.

Device Story

Infrascanner uses near-infrared spectroscopy (NIRS) to detect traumatic supratentorial hematomas. Device inputs include regional NIR light absorbance measurements from the patient's head; sensor is optically coupled via two disposable light guides in a 'hairbrush' configuration. Principle of operation relies on differential intracranial hemoglobin concentration between hematoma sites and normal brain tissue. Used in acute hospital settings by trained physicians or under physician direction. Examination takes approximately two minutes. Output provides information regarding potential hematoma development; clinicians use this to assess the need for CT scans. Device serves as an adjunctive tool to clinical evaluation; it is intended to rule in hematomas, not rule them out. Benefits include early identification of potential intracranial hematomas in head trauma patients.

Clinical Evidence

Clinical study enrolled 464 patients (aged 6 months–18 years) in emergency departments; 344 met inclusion criteria. Study complemented by literature meta-analysis. Results: Sensitivity 88.9% (2-12 yrs) and 85.7% (12-18 yrs); Specificity 72.3% (2-12 yrs) and 73.4% (12-18 yrs). Diagnostic performance was independent of age, hair/skin color, and race. Bench testing used multi-layered solid/liquid optical phantoms (silicone, intralipid, carbon black, titanium dioxide) to simulate human tissue, confirming repeatability, reproducibility, and agreement across age groups and skin types.

Technological Characteristics

Noninvasive NIRS-based sensor. Class I NIR-based sensor. Optically coupled via two disposable light guides in 'hairbrush' configuration.

The Infrascanner is indicated for use by Physicians, or under the direction of a physician, who has been trained in the use of the device. | | Device Description | The device is a noninvasive device, which uses near-infrared spectroscopy ("NIRS") to provide early information about the possible development of traumatic supratentorial hematomas in patients presenting to hospitals with head trauma. This technology involves comparing regional differences in absorbance of NIR light. The application of NIRS to hematoma evaluation is based on the principle that intracranial hemoglobin concentration will differ where a hematoma is present, compared to hemoglobin concentrations in normal intracranial regions. The system consists of a Class I NIR-based sensor. The sensor is optically coupled to the patient's head through two disposable light guides in a "hairbrush" configuration. Examination with the Infrascanner is performed through placement of the sensor on designated areas of the head that represent the most common locations for traumatic hematoma. The examination is designed to be performed within two minutes. | | Technological Characteristics | The device remain unchanged from the predicate clearances Bench testing comparing the subject device to the predicate using a pediatric laboratory model(s) of brain hematoma as compared to adult laboratory models. Testing included repeatability and reproducibility; agreement tests, and skin color tests; these results established device performance metrics across a range of simulated hematoma sizes, depths, and for light and dark skin and for bench hematoma models of adult and children 2 and above. | {4}------------------------------------------------ Bench testing demonstrated that device functioned as intended. Testing comparing to the predicate was conducted using a hematoma model to provide an approximation of human tissue. Testing included repeatability and reproducibility. Results were consistent with the expected result. Performance was substantially similar for both models across a range of age groups, depths and sizes of hematomas, and for skin types. Additional laboratory testing demonstrated the comparability of the device and its predicate over the range of optical densities. Four types of tests were conducted in order to evaluate substantial equivalence Repeatability / Reproducibility to assess the degree of agreement between measurements conducted on . the same device. The repeatability and reproducibility test data involved repeat observations with three different systems for each of the two models. Model hematomas of 5 mL and 50 mL were evaluated at depths below the skull of shallow and deep ranges at 0 cm, and 3 cm . Agreement test to assess the degree of agreement between measurements conducted by Model 2000 and Model 2500. The agreement test data were collected for one system of each model for hematomas of size 5 mL and 50 mL . Skin color test to assess the effect of the skin color on the measurements conducted by Model 2000 and Model 2500. The evaluation of the potential impact of skin color was performed for both models with hematoma size of 5 mL at depths of 0 and 2 cm, and without a model hematoma in the tank . Pediatric test to assess the effect of age on the degree of agreement between measurements conducted by Model 2000 and Model 2500. The potential effect of age on the measurements by the two models was tested using one system of each model for hematomas of size 5mL and 50 mL at 0 and 3 cm depths, on the phantom side mimicking the head of a 6 months old A 4-corners approach was used the selection and testing of the hematoma size and depth and for the age groups Small (5 ml) and large (50 ml) hematomas ● Superficial (0 cm) and deep (2 and 3cm) hematomas . Adult (>18 years old) and infant (6 months old) ages were tested A mixed multi-layered solid and liquid optical head phantom mimicking human tissue was used in the test. For brain tissue optical parameters intralipid was used to control the scattering properties and a calibrated ink to control absorption properties. Modeled layers of skin, scalp, skull and CSF with the liquid brain layer and blood were used to simulate brain hematoma. Each of the phantom walls were built to mimic different age groups. Silicone was selected for building the phantom due to a close match to the mechanical properties of tissue. Carbon black was used as the absorbing agent, and Titanium Dioxide was used as the scattering agent. The optical absorption and scattering properties of each layer were confirmed further by optical frequency-domain measurement systems. The optical properties of the CSF laver were those of water. Thin neutral density (ND) Wratten 2 film filters were placed over the phantom to adjust the signal level to OD values observed in the clinical studies for patients with different skin color. The thickness of the film filters is similar to the thickness of human skin. Using those filters, the OD values in the new lab tests covered the range of OD to simulate light-skinned patients and OD to simulate dark skinned subjects. The attenuation values of the filters were selected to match the OD values observed in the clinical studies. The brain model was filled with water, intralipid for scattering and a black ink for absorption. This mixture created a simulation of brain tissue. Our approach is to use whole blood as a hematoma model was used in this test. The flat hematoma model was built using a rectangular frame, inserted into a ball, and filled with blood. The rectangular frame forced the shape of the hematoma to remain relatively flat. A clinical study was carried out in the Emergency Departments large urban quaternary care academic medical centers on males or females aged 6 months – 18 years. 464 patients were enrolled and 344 met inclusion for primary data analysis. In these patients, 10.5% had evidence of a hematoma on HCT, and 4.7% had qualifying hematomas. This clinical study data was complemented with a literature review meta-analysis to provide the following age-specific performance estimates and confidence intervals in the newly indicated pediatric population subgroups with comparison to the predicate adult population performance estimates: Clinical data Diagnostic performance was independent of age (divided by quartile), hair/skin color, and race. Diagnostic performance was independent of whether three (43% 149/344) or four (57% 195/344) brain regions were assessed. {5}------------------------------------------------ | | Infrascanner performance in pediatric and adult subgroups | | | | |----------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------|-------------------------|-------------------------| | | 2-12 Years Old | 12-18 Years Old | Adults K080377 | | | | Total | 220 | 146 | 383 | | | No Hematomas | 202 | 139 | 320 | | | Hematomas | 18 | 7 | 63 | | | Sensitivity | 88.9% 65.3% to 98.6% | 85.7% 42.1% to 99.6% | 74.6% 62.1% to 84.7% | | | Specificity | 72.3% 65.6% to 78.3% | 73.4% 65.2% to 80.5% | 81.6% 76.9% to 85.7% | | | PPV | 22.2% 17.8% to 27.4% | 14.0% 9.7% to 19.6% | 44.3% 37.8% to 51.1% | | | NPV | 98.6% 95.2% to 99.6% | 99.0% 94.3% to 99.8% | 94.2% 91.4% to 96.2% | | | PPV - Positive Predictive Value, NPV - Negative Predictive Value. | | | | | | Sensitivity, specificity, PPV and NPV values include also the 95% confidence intervals | | | | | Substantial Equivalence | The subject device is as safe and effective as the predicate device.
