Patent number: 11896789Abstract: A device and system for flushing a shunt catheter utilizes the available cerebrospinal fluid (CSF) to flush a blocked catheter. The CSF is pressurized to a predetermined amount and then allowed to suddenly, rapidly and forcefully purge any occlusions. The rapid release of CSF produces flow jets from the catheter pores into the ventricle. This impulse, or “cough”, will push and divert choroid plexus and/or other blockages away from the pores. The device and system may then be allowed to refill at a slow rate, thus reducing the possibility of rapid suction of fluid back into the system and the attendant possibility of drawing the choroid plexus back into the pores. The catheter at the proximal end may also include back-up pores that can be opened to restart flow from the ventricle should the primary pores remain blocked after a flushing attempt.Type: GrantFiled: October 16, 2019Date of Patent: February 13, 2024Assignee: Children's Medical Center CorporationInventors: Joseph Madsen, Tomer Anor

Patent number: 11872333Abstract: An apparatus for locating and venting pathogen cells in blood. A cassette has a plurality of thin holding chambers that are filled with blood drawn from a patient. A light source illuminates each of the holding chambers and passes light to an underlying sensor array such that the cells in the blood produce shadow images of the cells in the sensor array. A processor performs pattern recognition to identify and locate the pathogen cells by use of an image library. After the pathogen cells are located, a pump is operated to move the identified cells to a processing zone. When each identified cell reaches the processing zone, a control voltage is generated to open a valve to vent the identified pathogen cells. The pump refills the cassette holding chambers, returns the processed blood to the patient, and the procedure is repeated for a treatment time period.Type: GrantFiled: July 25, 2022Date of Patent: January 16, 2024Inventors: William M. Gosney, Dale B. Nixon
