Patent number: 11633111Abstract: Fluid introduction into the patient during surgery can be tracked more accurately. For example, saline is often introduced to a patient to clean an operating site. The saline is taken from a sterile bucket and introduced to the patient. In one described approach, the system senses the volume or weight of fluid in the sterile bucket and determines any decrease in the volume or weight to be an introduction of fluid to the patient. If, however, additional saline is added to the bucket, that addition is not counted in the fluid tracking and the further decrements from that new fluid amount is what is used to track fluid addition to the patient.Type: GrantFiled: October 17, 2016Date of Patent: April 25, 2023Inventor: Alexander Y.

Patent number: 10518069Abstract: An implantable valve assembly including a drainage catheter having a central lumen transitioning into a plurality of distinct branch lumen made of a shape memory material. A bioabsorbable dip coating secures the distal end of the plural distinct branch lumen together in physical contact with one another. Each branch lumen has an outer perimeter comprising at least one of a first outer surface section and a second outer surface section. In a secured state with the plural distinct branch lumen held together by the dip coating fluid is prohibited from passing through the holes defined in the first outer surface section. Bioabsorbable blocking members disposed about the outer perimeter of the assembled branch lumen mask holes defined in the second outer surface section prohibiting fluid from entering therein. In a time staggered fashion, the bioabsorbable elements absorb exposing new holes through which the fluid drains.Type: GrantFiled: October 28, 2016Date of Patent: December 31, 2019Assignee: Integra LifeSciences Switzerland SarlInventors: Thomas Boden, Jr., Alan J.

Patent number: 10441716Abstract: The control device is used to control delivery of fluids from a multi-fluid delivery system during a medical injection procedure. The fluid delivery system includes an injector used to deliver injection fluids to a patient. The control device is operatively associated with the injector for controlling discrete flow rates of injection fluids delivered to the patient. The control device includes first and second actuators associated with the manual control device, and an electronic substrate disposed within the manual control device and having a conductive pattern. The first actuator is operatively associated with the conductive pattern. The conductive pattern includes a plurality of predetermined digital values corresponding to discrete flow rates of injection fluids to be delivered by the injector.Type: GrantFiled: January 8, 2018Date of Patent: October 15, 2019Assignee: BAYER HEALTHCARE LLCInventors: Ralph H. Schriver, Thomas P. Joyce, Michael Riley, William D. Barlow

Patent number: 10441725Abstract: A dose setting mechanism for a drug delivery device includes a primary drug delivery assembly and a secondary drug delivery assembly. The dose setting mechanism includes a primary dose dial component for setting a dose in the primary drug delivery assembly and a secondary dose dial component for setting a dose in the secondary drug delivery assembly. The primary dose dial component and the secondary dose dial component are configured to rotate during dose setting. A gear mechanism is configured such that in a first phase of the dose setting, rotation of the primary dose dial component is transferred to the secondary dose dial component and such that in a second phase of the dose setting, the secondary dose dial component is decoupled from the primary dose dial component such that rotation of the primary dose dial component is prevented from being transferred to the secondary dose dial component.Type: GrantFiled: May 27, 2015Date of Patent: October 15, 2019Assignee: Sanofi-Aventis Deutschland GMBHInventors: Matthew Meredith Jones, Samuel Keir Steel, Neal Alexander Blundred, Joseph Butler, Robert Frederick Veasey, David Plumptre
