static low voltage fuse based cell with high voltage Programming
2002Co-Authors: Martin S Denham, Mohsen Alavi, K Mistry, Patrick J Ott, Rachael J Parker, Paul Gregory Slankard, Wenliang ChenAbstract:A fuse-based cell. The fuse-based cell includes a fuse with a Programming Device electrically coupled to the fuse to program the fuse. A sensing Device is electrically coupled to the fuse to sense a Programming state of the fuse. A clamping Device is electrically coupled to the sensing Device to control voltages across the sensing Device during Programming. A pass Device is electrically coupled to the sensing Device to control voltages across the sensing Device during sensing.

static low voltage fuse based cell with high voltage Programming
2006Co-Authors: Paul F NewmanAbstract:A fuse-based cell is described. The fuse-based cell includes a fuse with a Programming Device coupled to the fuse to program the fuse. A sense Device is coupled to the fuse to sense a Programming state of the fuse. A pass Device is coupled to the sense Device to control voltages across the sense Device during sensing. A switch is coupled to the sense Device and a load is coupled to the switch. The switch isolates the load and the sense Device from high voltage during a Programming event. The load sets a read current used to read the state of the fuse.

Adjustable shunt valve reProgramming at home : Safety and feasibility. Commentary
Neurosurgery, 2007Co-Authors: Christian W. Sikorski, David Rosen, David M. Frim, J. Gordon Mccomb, Paul H. Chapman, Leslie N. SuttonAbstract:OBJECTIVE: Shunt valve resistance changes using a specialized magnetic Programming Device permit noninvasive changes to cerebrospinal fluid drainage. In selected cases between 2001 and 2005, patients and families used shunt valve Programming Devices at home. This study examines the safety and efficacy of this practice. METHODS: We conducted a retrospective review of the medical records of patients who had been given a shunt valve-Programming Device for home use. A survey was mailed to patients or family members requesting information regarding their experiences with the shunt valve Programming Device. Patient and family responses were tabulated and a statistical analysis was performed. RESULTS: Twenty patients or families returned the survey. The median patient age was 19.6 years (range, 6-48 yr); 25% were male. Seventeen patients had pseudotumor cere-bri, one had an arachnoid cyst, and two had slit ventricle syndrome. Fifteen patients had lumboperitoneal shunts, one had a ventriculoperitoneal shunt, three had cisterna magna shunts, and one had an arachnoid cyst-to-peritoneal shunt. No adverse events were attributable to the use of the home shunt valve programmer. Thirty-five percent of respondents used the programmer at least once every week, 40% used the programmer between once a week and once a month, and 25% used the programmer less frequently than once per month. Overall, 85% of respondents reported that they benefited "very much" from the use of a home shunt valve programmer and 15% of respondents benefited "somewhat." CONCLUSION: Providing shunt valve Programming Devices to selected patients for home use is a safe practice associated with high patient satisfaction. However, the selection of appropriate patients, comprehensive patient education, and close patient-physician communication are crucial to the success of this practice.

Maladjustment of Programmable Ventricular Shunt Valves by Inadvertent Exposure to a Common Hospital Device
CORE Scholar, 2018Co-Authors: Fujimura R., Lober, Robert M., Kamian K., Kleiner L.Abstract:Background: Programmable ventricular shunt valves are commonly used to treat hydrocephalus. They can be adjusted to allow for varying amounts of cerebrospinal fluid (CSF) flow using an external magnetic Programming Device, and are susceptible to maladjustment from inadvertent exposure to magnetic fields.Case Description: We describe the case of a 3‑month‑old girl treated for hydrocephalus with a programmable StrataTM II valve found at the incorrect setting on multiple occasions during her hospitalization despite frequent reProgramming and surveillance. We found that the Vocera badge, a common hands‑free wireless communication system worn by our nursing staff, had a strong enough magnetic field to unintentionally change the shunt setting. The Device is worn on the chest bringing it into close proximity to the shunt valve when care providers hold the baby, resulting in the maladjustment.Conclusion: Some commonly used medical Devices have a magnetic field strong enough to alter programmable shunt valve settings. Here, we report that the magnetic field from the Vocera hands‑free wireless communication system, combined with the worn position, results in shunt maladjustment for the StrataTMII valve. Healthcare facilities using the Vocera badges need to put protocols in place and properly educate staff members to ensure the safety of patients with StrataTM II valves
