Patent number: 11944768Abstract: A method of using a catheter assembly for inserting in a fluid filled space in a body includes providing a main body having a first end portion and a second end portion. The first end portion is positioned within the fluid filled space. The second end portion is adjusted to extend outwardly from the fluid filled space when the first end portion is positioned within the fluid filled space. A catheter tip is connected to the second end portion of the main body. The catheter tip includes a housing having a cavity defined therein and a rotating element positioned within the fluid filled space. The rotating element is rotated within the cavity of the housing to impart movement of the first end portion of the main body within the fluid filled space.Type: GrantFiled: August 17, 2020Date of Patent: April 2, 2024Assignee: Washington UniversityInventors: Eric Leuthardt, Guy Genin, Matthew Smyth, David Limbrick, Daniel Moran, Lihong Wang, Aaron McLaughlin, Manish Shah, Alexander Yang, Samuel Stone, Devon Haydon, Michael Winek, Richard Marcus

Patent number: 10517755Abstract: Passive prosthetic devices for focally cooling a brain and methods for inhibiting seizures are disclosed. The prosthetic devices replace a thermally insulating bone flap with a thermally conductive insert having an inner surface that contacts the relatively warm meninges or brain and an outer surface that contacts the relatively cool scalp. In an embodiment, the prosthesis is unitary; in another, a biocompatible casing is filled with a highly conductive core; in another, a filled polymer block is attached to a plate; and in another, the bone flap is filled with a conductive polymer. In one embodiment, a filled polymer containing elements that exhibit the magnetocaloric effect provide heat transfer that can be enhanced by application of a suitable magnetic field. Focal cooling as low as 1.2° C. has been found effective at inhibiting seizures.Type: GrantFiled: November 14, 2016Date of Patent: December 31, 2019Assignees: UNIVERSITY OF WASHINGTON, WASHINGTON UNIVERSITY, REGENTS OF THE UNIVERSITY OF MINNESOTAInventors: Raimondo D'Ambrosio, Jason Fender, Jeffrey Ojemann, John W. Miller, Matthew Smyth, Steven M. Rothman

Patent number: 8591562Abstract: A device for cooling the central nervous system (e.g., the brain) is disclosed that is specifically designed to provide cooling of an injured central nervous system for neuroprotective, antiepileptogenic, and/or antiepileptic treatments. In one embodiment, a portion of the cooling device is placed in a recess formed by removal of a portion of a patient's skull. An embedded heat-collecting portion of the cooling device is formed to fit in the location of the formed recess and a thermally conductive material of the heat-collecting portion is placed adjacent the dura mater to provide the desired degree of cooling. A heat-dissipating external plate is in thermal contact with the internal plate, and can be selectively sized according to a specific purpose.Type: GrantFiled: December 2, 2009Date of Patent: November 26, 2013Assignees: University of Washington, Regents of the University of Minnesota, Washington University in St. LouisInventors: Raimondo D'Ambrosio, Matthew Smyth, Steven Mark Rothman, John W.
