Publication number: 20220280276Abstract: There is disclosed a porous emboli deflector for preventing cerebral emboli while maintaining cerebral blood flow during an endovascular or open surgical procedure. The device prevents the entrance of emboli of a size able to cause stroke (such as greater than 100 microns) from entering either the right or left common carotid arteries, and/or the right or left vertebral arteries by deflecting emboli downstream of these vessels. The device can be placed prior to any manipulation of the heart or aorta allowing maximal protection of the brain during the index procedure. The deflector has a low profile within the aorta which allows sheaths, catheters, or wires used in the index procedure to pass. Also disclosed are methods for insertion and removal of the deflector.Type: ApplicationFiled: May 24, 2022Publication date: September 8, 2022Inventors: Judith T. Carpenter, Jeffrey P. Carpenter, David A. Rezac, Jeffrey C. Cerier, Richard C. Fortier, Timothy W. Robinson

Patent number: 11212878Abstract: A system for heating a selected section of a conductive ribbon comprises a non-conductive base and conducting pads. Further, the system comprises a variable voltage power supply electrically coupled to the conducting pads and a sensor. A processor is programmed to enable the variable power supply to produce a voltage signal across the conducting pads to cause the selected section, which includes a biological sample and is clamped to the non-conductive base via the conducting pads, to heat up. The processor receives, from the sensor, an electrical measurement. A correction for the voltage signal is computed based on the measurement to achieve a desired temperature, wherein the desired temperature is for processing the biological sample and the correction accounts for a variance in the selected section. The applied voltage signal is adjusted based upon the correction to regulate the selected section of at the desired temperature for a time.Type: GrantFiled: April 1, 2019Date of Patent: December 28, 2021Assignee: BATTELLE MEMORIAL INSTITUTEInventor: Jeffrey P.

Patent number: 10054406Abstract: A device comprises a reactive semiconductor bridge including a conductive metal, a reactive material, and an overcoat. When a high current passes through the reactive semiconductor bridge, the conductive metal vaporizes into a high temperature plasma. The reactive material is coupled to the conductive metal such that the conductive metal experiences an exothermic reaction to the plasma. When the conductive metal turns to plasma, the overcoat material absorbs at least a part of the exothermic reaction of the reactive material and breaks into a plurality of particles that are propelled away from the bridge. A gap is disposed between the overcoat and a membrane, and an explosive material couples to the membrane. The plurality of particles crosses the gap and penetrates the membrane to ignite the explosive material in response to being propelled away from the bridge.Type: GrantFiled: September 23, 2016Date of Patent: August 21, 2018Assignee: BATTELLE MEMORIAL INSTITUTEInventors: Thomas E. Burky, Jeffrey P. Carpenter, Laura Dues
