Publication number: 20230181883Abstract: Systems and methods for treating biologic fluids are disclosed. Some disclosed embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject, heat CSF to a target temperature, cool CSF to a target temperature, apply light treatment to CSF, separate cells via their dielectric properties, apply spiral and/or centrifugal separation, introduce additives to target particles, and/or apply combinations thereof. The method may include the steps of withdrawing fluid comprising CSF, treating the fluid, and returning a portion of the treated fluid to the subject. During operation of the system, various parameters may be modified, such as flow rate.Type: ApplicationFiled: February 3, 2023Publication date: June 15, 2023Applicant: MINNETRONIX, INC.Inventors: BLAKE HEDSTROM, SHIVANAND P.

Publication number: 20230120296Abstract: Systems and methods for filtering materials from biologic fluids are discussed. Embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject. In an example, CSF is separated into a permeate and retentate using a tangential flow filter. The retentate is filtered again and then returned to the subject with the permeate. During operation of the system, various parameters may be modified, such as flow rate and waste rate.Type: ApplicationFiled: December 15, 2022Publication date: April 20, 2023Applicant: MINNETRONIX, INC.Inventors: EMILY ROLFES MEYERING, GARY SEIM, ABHI VASE, BEN KREHBIEL, BLAKE HEDSTROM, AARON MCCABE, JACK MONDRY

Patent number: 11253314Abstract: The disclosure describes devices, systems, and techniques for identifying and treating bladder dysfunction. In one example, a method includes identifying one or more focal points at respective locations of bladder tissue of a bladder of a patient, the one or more focal points initiating coordinated contractions of a detrusor muscle. The method may also, or alternatively, include ablating, for each of the one or more focal points, a respective portion of the bladder tissue at the respective location of the focal point. Ablation of these targeted portions of the bladder tissue may reduce the coordinated contractions of the detrusor muscle and alleviate overactive bladder symptoms.Type: GrantFiled: May 21, 2020Date of Patent: February 22, 2022Assignee: Medtronic, Inc.Inventors: Thaddeus S. Brink, Blake A. Hedstrom, Dwight E. Nelson, Ashish Singal, Xin Su

Patent number: 11045650Abstract: In general, techniques, methods, systems, and devices for delivering high frequency neurostimulation to control one or more pelvic disorders are described. In one example, a method includes identifying, by a medical device configured to be at least partially implanted in a patient, an indication to inhibit bladder activity. The medical device generates, in response to identifying the indication, electrical stimulation therapy comprising first electrical stimulation pulses comprising a first frequency greater than or equal to about 500 Hertz and less than or equal to about 5,000 Hertz. Further, the medical device delivers the electrical stimulation therapy to a target nerve selected from a group consisting of: a sacral nerve, a pelvic nerve, a tibial nerve, and a pudendal nerve of the patient.Type: GrantFiled: December 5, 2017Date of Patent: June 29, 2021Assignee: Medtronic, Inc.Inventors: Thaddeus S.

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.
