20080208113 | Fully Automated Control System for Type I Diabetes - An augmented, adaptive algorithm utilizing model predictive control (MPC) is developed for closed-loop glucose control in type 1 diabetes. A linear empirical input-output subject model is used with an MPC algorithm to regulate blood glucose online, where the subject model is recursively adapted, and the control signal for delivery of insulin and a counter-regulatory agent such as glucagon is based solely on online glucose concentration measurements. The MPC signal is synthesized by optimizing an augmented objective function that minimizes local insulin accumulation in the subcutaneous depot and control signal aggressiveness, while simultaneously regulating glucose concentration to a preset reference set point. The mathematical formulation governing the subcutaneous accumulation of administered insulin is derived based on nominal temporal values pertaining to the pharmacokinetics (timecourse of activity) of insulin in human, in terms of its absorption rate, peak absorption time, and overall time of action. | 08-28-2008 |

20160144114 | FLUID DELIVERY SYSTEMS AND METHODS - A method of dispensing fluid includes three processes. A first one of these processes includes pumping fluid into a resilient variable-volume dispensing chamber. The dispensing chamber is in series with a normally present finite fluid impedance and an output. The impedance is sufficient so as to cause expansion of the dispensing chamber as it receives pumped fluid even while some fluid flows through the output. Another one of these processes includes repeatedly measuring a parameter related to volume of the dispensing chamber over time. A third one of these processes includes controlling the pumping of fluid based on repeated measurements of the parameter to produce a desired fluid flow through the output. A corresponding system for dispensing fluid implements these processes. | 05-26-2016 |

20160158440 | Simplified Microplegia Delivery System - Cardioplegia is a mixture of blood and cardioplegic solution administered through the coronary vessels to protect the myocardium during cardiopulmonary bypass procedures. Microplegia describes the use of concentrated cardioplegic solution during cardioplegia delivery in an effort to reduce hemodilution and improve myocardial protection. This new apparatus is designed to deliver concentrated cardioplegic solution during cardioplegia delivery. The apparatus features cost saving opportunities, adaptability to any cardioplegia system, simplified delivery options, and safety options. Cardioplegia flow sensor integration to the apparatus allows for convenient auto start/stop as well continuously updated flow-based delivery of the cardioplegic solution during cardioplegia delivery. | 06-09-2016 |
