Manufacturer Narrative
This value is the average age of the patients reported in the article as specific patients could not be identified. Patient gender is the majority value of patients in the study. Patient weight not available from the site. Event date is the online publish date of the publication. Device lot number, or serial number, unavailable. 510(k) is dependent upon field d4 and is, therefore, unavailable. No parts have been received by the manufacturer for evaluation.

Minimally invasive intracerebral hematoma evacuation using a novel cost-effective tubular retractor: single-center experience. World neurosurg. (2021) 150:42-53. Https://doi. Org/10. 1016/j. Wneu. 2021. 03. 083 background: spontaneous intracerebral hematoma (ich) is a common disease with a dismal overall prognosis. Recent development of minimally invasive ich evacuation techniques has shown promising results. Commercially available tubular retractors are commonly used for minimally invasive ich evacuation yet are globally unavailable. Methods: a novel u. S. $7 cost-effective, off-the-shelf, atraumatic tubular retractor for minimally invasive intracranial surgery is described. Patients with acute spontaneous ich underwent microsurgical tubular retractoreassisted minimally invasive ich evacuation using the novel retractor. Patient outcome was retrospectively analyzed and compared with open surgery and with commercial tubular retractors. Results: ten adult patients with spontaneous supratentoria ich and median preoperative glasgow coma scale score of 10 were included. Ich involved the frontal lobe, parietal lobe, occipitotemporal region, and solely basal ganglia in 3, 3, 2, and 2 patients, respectively. Mean preoperative ich volume was 80 ml. Mean residual hematoma volume was 8. 7 ml and mean volumetric hematoma reduction was 91% (median, 94%). Seven patients (70%) underwent >90% volumetric hematoma reduction. The total median length of hospitalization was 26 days. On discharge, the median glasgow coma scale score was 12. 5 (mean, 11. 7). Thirty to 90 days' follow-up data were available for 9 patients (90%). The mean follow-up modified rankin scale score was 3. 7 and 5 patients (56%) had a modified rankin scale score of 3. Conclusions: the novel cost-effective tubular retractor and microsurgical technique offer a safe and effective method for minimally invasive ich evacuation. Cost-effective tubular retractors may continue to present a valid alternative to commercial tubular retractors. Reported events: 1) 72 year old patient experienced a second spontaneous ich anatomically unrelated and it was noted that the ich resolved spontaneo usly 2) 76 year old patient experienced a subdural effusion with no mass effect that was noted to resolve spontaneously 3) 60 year old patient experienced seizures and vap that were resolved with tx 4) 44 year old patient experienced a cns infection that was resolved withtx 5) 68 year old patient experienced a cns infection that was resolved with tx 6) 48 year old patient experienced renal failure, cap and seizures that were resolved with tx 7) 42 year old patient experienced a cns infection that was resolved with tx 8) 71 year old patient experienced a suspected infected cerebral fluid collection that underwent subsequent debridement.
