Publication number: 20230135271Abstract: Some embodiments are directed to methods for serially expanding an artificial heart valve within a pediatric patient. For example, the artificial heart valve can be implanted into the pediatric patient during a first procedure, and then expanded during a second procedure to accommodate for the pediatric patient’s growth. Some embodiments include introducing an expander into the implanted valve when the frame is expanded to a first working diameter, and then actuating the expander to expand the frame to a second working diameter greater than the first working diameter, to accommodate for the pediatric patient’s growth.Type: ApplicationFiled: November 7, 2022Publication date: May 4, 2023Applicants: Baylor College of Medicine, William Marsh Rice UniversityInventors: Henri JUSTINO, Daniel HARRINGTON, Kwonsoo CHUN

Patent number: 11464632Abstract: Some embodiments are directed to a transcatheter and serially-expandable artificial heart valve, e.g., to be minimally-invasively implanted into a pediatric patient during a first procedure, and then expanded during a second procedure to accommodate for the pediatric patient's growth. Some embodiments include an expandable frame having a compressed, delivery configuration, and an expanded, deployed configuration, in which the valve is implantable within the patient. The valve can have a first working condition when the frame is expanded to a first diameter and a second working condition when the frame is expanded to a second diameter greater than the first diameter. The valve can include a plurality of leaflets configured to accommodate the expansion of the frame and growth of the patient.Type: GrantFiled: September 13, 2021Date of Patent: October 11, 2022Assignees: Baylor College of Medicine, William Marsh Rice UniversityInventors: Henri Justino, Daniel Harrington, Kwonsoo Chun

Publication number: 20200000581Abstract: One aspect of the invention provides and artificial, flexible valve indlucding: a stent defining a wall and a plurality of leaflets extending from the wall of the stent. The plurality of leaflets form a plurality of coaptation regions between two adjacent leaflets. The coaptation regions include extensions along a z-axis and adapted and are configured to form a releasable, but substantially complete seal when the leaflets are in a closed position. Another aspect of the invention provides an artificial, flexible valve including: a stent defining a wall and a plurality of leaflets extending from the wall of the stent. Each of the plurality of leaflets terminates in a commissure line. The commissure lines devi-ate from a hyperbola formed in the x-y plane by at least one deviation selected from the group consisting of: a deviation in the z-direction and one or more curves relative to the hyperbola.Type: ApplicationFiled: September 6, 2019Publication date: January 2, 2020Applicants: Baylor College of Medicine, William Marsh Rice UniversityInventors: Henri JUSTINO, Daniel HARRINGTON, Kwonsoo CHUN

Publication number: 20060051727Abstract: A method on a computing device is provided for enhancing the memory and cognitive ability of an older adult by requiring the adult to spatially match pairs of graphically presented response buttons that are associated with aurally presented stimuli which is processed by the computing device. An adult is presented with a grid of response buttons that have been paired with aural stimuli. As the adult selects a response button, its processed aural stimuli is presented. The adult is required to remember which response button is associated with which aural stimuli, and sequentially select response buttons having the same aural stimuli. As the adult sequentially selects response buttons having the same aural stimuli, the response button pair is removed. The number of response buttons presented in a trial, and the amount of processing applied to the stimuli adapts to the adults success or failure in completing trials.Type: ApplicationFiled: October 6, 2005Publication date: March 9, 2006Applicants: Neuroscience Solutions CorporationInventors: Daniel Goldman, Joseph Hardy, Henry Mahncke, Michael Merzenich, Jeffrey Zimman, Justin Char, Daniel Harrington
