The Barrow Innovation Center Case Series: A Novel 3-Dimensional-Printed Retractor for Use with Electromagnetic Neuronavigation Systems.
No full textOBJECTIVE: The Barrow Innovation Center consists of an educational program that promotes interdisciplinary collaboration among neurosurgery, legal, and engineering professionals to foster the development of new medical devices. This report describes a common issue faced during the placement of ventricular shunts for the treatment of hydrocephalus and the solution to this problem that was developed through the Barrow Innovation Center.
METHODS: Neurosurgery residents involved in the Barrow Innovation Center presented the problem of ferromagnetic retractors interfering with pinless image-guidance systems at a monthly meeting. Potential solutions were openly discussed by an interdisciplinary committee of neurosurgeons, patent lawyers, and biomedical engineers. The committee decided to pursue development of a novel self-retaining retractor made of nonferromagnetic material as a solution to the problem.
RESULTS: Each retractor design was tested in the cadaver laboratory for size and functionality. A final design was chosen and used in a surgical case requiring ventriculoperitoneal shunt placement. The new retractor successfully retracted the scalp without interfering with the electromagnetic image-guidance system.
CONCLUSIONS: Through the interdisciplinary Barrow Innovation Center program, a newly designed, 3-dimensional-printed skin and soft-tissue retractor was created, along with an innovative universal shunt retainer. Through this integrated program dedicated to surgical innovation (i.e., the Barrow Innovation Center), the process of developing and implementing new technology at our institution has been streamlined, creating a culture of innovation within the neurosurgery training program
Barrow Innovation Center: A 5-Year Update and Future Direction
No full textOBJECTIVE: The rich history of neurosurgical innovation served as a model for the Barrow Innovation Center\u27s establishment in 2016. The center\u27s accomplishments are summarized in hopes of fostering the development of similar centers and initiatives within the neurosurgical and broader medical community. METHODS: A retrospective review (January 2016-July 2021) of patent filings, project proposals, and funding history was used to generate the data presented in this operational review. RESULTS: Through the 5-year period of analysis, 55 prior art searches were conducted on new patentable ideas. A total of 87 provisional patents, 25 Patent Cooperation Treaty applications, and 48 national stage filings were submitted. In partnership with Arizona State University, the University of Arizona, California Polytechnic State University, and Texas A&M University, a total of 27 multidisciplinary projects were conducted with input from multispecialty engineers and scientists. These efforts translated into 1 startup company and 2 licensed patents to commercial companies, with most remaining ideas and project efforts awaiting interest from industry. CONCLUSIONS: The multidisciplinary collaborative environment embodied by the Barrow Innovation Center has revolutionized the innovative and entrepreneurial environment of its home institution and enabled neurosurgical residents to get a unique educational experience within the realm of innovation. The bottleneck within the workflow of ideas from conception to commercialization appears to be the establishment of commercial partners; therefore, future efforts within the center will be to establish a panel of industry partnerships to enhance the exposure of ideas to interested companies
Animals and Cotswold-Severn long-barrows: a re-examination.
No full textIn this paper new collaborative research is presented following a re-examination of the faunal remains and
architectural evidence from a selected number of Cotswold-Severn long barrow sites. Five different loci of
deposition are considered: ‘pre-barrow’ contexts; the chambers; the superstructure of the barrow and the
ditches; the forecourt; and blocking material. These spatial locations were chosen following research that has
demonstrated that these areas are likely to represent different temporal, as well as spatial, patterns of activity.
While the faunal remains are diverse in character, common themes observed at the sites include: the deposition
of complete or partial remains of foetal and young animals within chambers; the use of teeth and cranial
elements within blocking material; and, within each temporal context, the absence of clear evidence for feasting
and the importance of cattle, and the small but constant inclusion of wild mammals. This complexity of
practice has the potential to mature our thinking regarding the nature of human–animal relationships within
the early Neolithic of Britain and provide a secure foundation of evidence for subsequent interpretations

Iš viso ištirtas 115 m2 plotas. Tyrimus finansavo KVAD pagal apardytų ir ardomų archeologinių vietų tyrinėjimų programą.In 2004 in the Poviliškė barrow cemetery (Ignalina district) one barrow was investigated. The barrow was 0.9 m high and had 9.5 m in diameter. At foot there were two pits. In the centre of the barrow a cremation containing no burial items was found. Two another cremation graves, also containing no items, had been dug into the barrow later. The investigated barrow is attributable to the East Lithuanian Barrow Group and preliminary datable to the Middle or the Late Iron Age

ATL 2000 metais, V., 2002, p. 77-79; ATL 2001 metais, V., 2002, p. 97–99). Buvo ištirtas dar vienas kvartalinės linijos ardomas pilkapis R pilkapyno dalyje (iš viso 210 m² plotas). Tyrinėjimus finansavo KVAD pagal apardytų ir ardomų archeologinių vietų tyrimų programą [p. 80].In 2002 VU continued to explore the Jašiūnai (Geložė) barrow cemetery (Šalčininkai district, Jašiūnai). Destroyed barrow 5 was explored. According to the construction of the earth pile, the barrow was dated to the 7th-8th centuries. While exploring the barrow, only single cremated bones were found

Kaip ir kitus tyrinėtus šio pilkapyno pilkapius juos žalojo miško kvartalinė linija, priešgaisrinis arimas. Tirti pilkapiai buvo R bei ŠR pilkapyno dalyje.In 2004 the archaeological excavations of the Kurklių Šilas barrow cemetery (in Anykščiai district) were continued. In 2004 two barrows were investigated (an area of 344 m2 in total). The barrow No. 11 (41) was 0.65-0.75 m high and had 13 x 9 m in diameter. It was surrounded by an unbroken ditch. Neither burials, nor loose artefacts were found in the barrow. According to the construction the barrow is datable to the 8th-10th century and should be attributed to the Eastern Lithuanian Barrow Culture. Excavations of the barrow No. 12 (106) revealed that this was not a barrow, but a mound formed during fire prevention earthworks
