Patent number: 11904106Abstract: The invention provides an improved indwelling urinary catheter of the inflatable type having a unique, low profile device by which to retain the catheter within the bladder, so that urine can be removed therefrom while avoiding obstruction to the descending fetal vertex during the process of labor and delivery. Thus, making it better suited for obstetrical applications. The retaining device consumes less obstructing volume in the bladder than that which would ordinarily be consumed by a conventional Foley-style balloon, whereby both the frequency and severity of fetal vertex obstruction and its resulting increased time of labor, operative delivery and injury to maternal urologic tissue can be reduced. The obstetrical foley retains the tradition Foley-style balloon distal to the improved low-profile laboring balloon for insufflation in the event a surgical delivery by cesarean section is indicated.Type: GrantFiled: January 20, 2021Date of Patent: February 20, 2024Inventor: Gregory Douglas Wood

Patent number: 11904140Abstract: The exemplary embodiments provide medicament delivery devices that use cost functions in their control systems to determine medicament dosages. The cost function may have a medicament cost component and a performance cost component. The exemplary embodiments may use cost functions having medicament cost components that scale asymmetrically for different ranges of inputs (i.e., different candidate medicament dosages). The variance in scaling for different input ranges provides added flexibility to tailor the medicament cost component to the user and thus provide better management of medicament delivery to the user and better conformance to a performance target.
