Patent number: 10010686Abstract: A system for controlled delivery of medicinal fluid includes a fluid pathway assembly defining a fluid pathway and including means for calculating a first calculated fluid flow rate using gas laws. The fluid pathway assembly has an inline flow sensor element received within the fluid pathway movable in response to fluid flowing in the fluid pathway. A flow control device is removably attached to the fluid pathway assembly and has a sensor for sensing a position of the inline flow sensor element in the fluid pathway, the position of the inline flow sensor element being representative of a second calculated fluid flow rate. The fluid pathway assembly includes a variable flow resistor adjustable to regulate a rate of fluid flow in the fluid pathway assembly. A drive mechanism attached to the flow control device is operably coupled to the variable flow resistor when the flow control device is attached to the fluid pathway assembly.Type: GrantFiled: January 29, 2014Date of Patent: July 3, 2018Assignee: Ivenix, Inc.Inventors: Jesse E. Ambrosina, Benjamin G. Powers

Patent number: 9907563Abstract: A fluid management system for use in a tissue resection procedure includes a controller. An inflow pump is operated by the controller and configured to provide fluid inflow through a flow path to a site in patient's body. An outflow pump is operated by the controller and configured to provide fluid outflow through a flow path from the site in patient's body. A motor driven resecting device may be provided for resecting tissue at the site. The controller is configured to actuate an inflow pump and an outflow pump in response to various signals and various algorithms are provided to provide malfunction warnings and assure safe operation.Type: GrantFiled: April 8, 2014Date of Patent: March 6, 2018Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Aaron Germain, Kyle Klein, Michael D. Walker, Robin Bek

Patent number: 9861747Abstract: Described and illustrated is a system for management of diabetes that includes an infusion pump, glucose sensor and controller with a method programmed into the controller. The infusion pump is configured to deliver insulin to a subject. The system provides the user with the ability to understand the effects of bolus insulin dosing upon their glucose levels. Specifically, the system provides a message that must include: (a) the trend of the user's glucose; (b) the recommended bolus; and (c) the actual bolus.Type: GrantFiled: December 5, 2013Date of Patent: January 9, 2018Assignee: LifeScan, Inc.Inventors: Sweta Chovanda, Carlos Omar Morales

Patent number: 9833571Abstract: An integrated diabetes management (IDM) system includes a safety layer which, in one configuration has two components, one located between a glucose sensor and a controller and a second component located between a controller and a pump, to monitor various aspects of signals and modify those signals for compatibility and safety purposes. In one application, the safety layer receives output control signals from a controller and modifies those control signals as a function of an actual amount of insulin delivered to the user. The safety layer allows for an increased level of safety in the IDM system and permits development of separate hardware and software upgrades with the safety layer assuring that compatibility between components will continue.Type: GrantFiled: October 30, 2014Date of Patent: December 5, 2017Assignee: Abbott Diabetes Care Inc.Inventor: Erwin S.

Patent number: 9833178Abstract: A method and an apparatus for measuring glucose level in the body fluid of a subject, typically blood glucose level, by measuring impedance of a body tissue, with two pairs of electrodes, two electrodes for injecting current into a body tissue and two electrodes for detecting the ensuing voltage of the body tissue. The body tissue is typically a sub-dermal or sub-cutaneous tissue. The measured impedance of the body tissue is used to correlate with directly determined glucose levels to determine the glucose level from the measured impedance. It is thus possible to determine body fluid glucose levels in a reliable and reproducible manner.Type: GrantFiled: May 4, 2015Date of Patent: December 5, 2017Assignee: D.T.R.
