Publication number: 20190105475Abstract: Systems, catheters, and methods for accessing and treating along the central nervous system are disclosed. An example system may include a system for ameliorating a symptom of bacterial meningitis in a patient. The system may include a catheter assembly having a first lumen with a distal port and a second lumen with a proximal port, said catheter being adapted to be introduced in a CSF space and said ports being spaced axially apart. A pump may be connectable between the first and second lumens to induce a flow of CSF therebetween. A filter component may be connectable between the first and second lumens. The filter component may be configured to remove one or more meningitis causing bacterial pathogen from the CSF, to thereby condition the cerebrospinal fluid.Type: ApplicationFiled: October 4, 2018Publication date: April 11, 2019Applicant: MINNETRONIX, INC.Inventors: SHIVANAND P.

Patent number: 10149933Abstract: Present embodiments are directed to measuring and calculating parameters to control and monitor a power transfer in an implanted medical device. The medical device may be implanted in a subject and typically includes an artificial heart or ventricle assist device. The system measures parameters and uses the parameters to calculate a coupling coefficient for coils that transfer power between an external primary and an implanted secondary. The system uses the calculated coupling coefficient to estimate heat flux being generated in the system. Based on the level heat flux detected, the system may issue alerts to warn the subject or control actions to mitigate the effects of the heat flux.Type: GrantFiled: July 24, 2015Date of Patent: December 11, 2018Assignee: Minnetronix, Inc.Inventors: Vlad Bluvshtein, Lori Lucke
