Patent number: 11938290Abstract: The present disclosure generally relates to systems and methods of use for draining cerebrospinal fluid (CSF) from a brain or a spinal canal in a subject, for example, to treat hydrocephalus or other conditions. In some embodiments, the disclosure relates to a device comprising a flow controller positioned within a conduit that allows CSF to flow through the conduit from a first end to a second end. This may allow the CSF to drain, for example, from an intradural space (such as a thecal sac) into, for example, a paraspinal space, paraspinal vein or other venous space, or peritoneal cavity. A variety of methods may be used to hold or anchor the device in place, for example, an expansion apparatus. In some embodiments, the device can be implanted percutaneously at a location along or within a subject's spinal column, thus reducing the need for surgery, general anesthesia, and hospitalizations.Type: GrantFiled: April 27, 2023Date of Patent: March 26, 2024Assignee: Mayo Foundation for Medical Education and ResearchInventors: Fredric B.

Patent number: 11938002Abstract: Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In one embodiment, a negative pressure source can provide negative pressure via a fluid flow path to a wound dressing comprising a stabilizing structure. The stabilizing structure can be inserted into a wound and collapse upon application of negative pressure to the wound when the stabilizing structure is positioned in the wound. A controller can in turn determine a measure of collapse of the stabilizing structure from a pressure in the fluid flow path while the negative pressure source maintains a magnitude of the pressure in the fluid flow path within a negative pressure range. The controller can output an indication responsive to the measure of collapse.Type: GrantFiled: July 21, 2022Date of Patent: March 26, 2024Assignee: Smith & Nephew, Inc.Inventors: Allan Kenneth Frazer Grugeon Hunt, William Joseph Jaecklein, Felix Clarence Quintanar
