Patent number: 12090301Abstract: Disclosed are a system, methods and computer-readable medium products that provide safety constraints for an insulin-delivery management program. Various examples provide safety constraints for a control algorithm-based drug delivery system that provides automatic delivery of a drug based on sensor input. Glucose measurement values may be received at regular time intervals from a sensor. A processor may predict future glucose values based on prior glucose measurement values. The safety constraints assist in safe operation of the drug delivery system during various operational scenarios. In some examples, predicted future glucose values may be used to implement safety constraints that mitigate under-delivery or over-delivery of the drug while not overly burdening the user of the drug delivery system and without sacrificing performance of the drug delivery system. Other safety constraints are also disclosed.Type: GrantFiled: May 6, 2019Date of Patent: September 17, 2024Assignee: INSULET CORPORATIONInventors: Jason O'Connor, Joon Bok Lee, Trang Ly, Yibin Zheng, Thomas Arnold Peyser, Jennifer Lena Schneider

Patent number: 11826520Abstract: The objectives for the designs presented herein can be for a variably flexible and kink-resistant catheter for vascular applications. The designs benefit from good compressive and tensile stiffness. A braided wire support structure can be disposed around an inner liner and an outer layer having a plurality of outer jackets of variable durometer. A metallic reinforcing layer can be cut from a hypotube and be used as the primary structure for catheter stiffness, reducing the reliance on and number of jackets to transition stiffness changes along the length of the catheter. The metallic reinforcing layer can have one or more ribbon cut segments and one or more axial hole patterns laser cut into the hypotube to progressively evolve the stiffness from proximally regions with more column stiffness and distal regions with greater lateral flexibility. The polymer jackets can be reflowed to bond the structure together.Type: GrantFiled: December 8, 2020Date of Patent: November 28, 2023Assignee: DePuy Synthes Products, Inc.Inventors: Pedro Pedroso, Chadwin Hanna
