  • Patent number: 10729849
    Abstract: An artificial pancreas system includes a continuous glucose monitoring device, a drug delivery device configured to exchange data with the continuous glucose monitoring device and containing a control algorithm, and possibly a remote controller configured to exchange data with the drug delivery device. The algorithm contains an insulin-glucose model, but is decoupled mathematically from the insulin injected by the user to offset the ingested carbohydrates. The control algorithm is designed to calculate two versions of insulin-on-board-patient-facing insulin-on-board (PFIOB) and system-facing insulin-on-board (SFIOB) to properly parse boluses and inform the system of only the insulin that is intended for high glucose correction, but not carbohydrate offsetting.

  • Patent number: 10688236
    Abstract: System and methods are provided for harvesting one or more organs, e.g., a lung from a donor body. In one embodiment, a distal end of a tubular member is introduced into the donor body's vasculature via a percutaneous access site, and the tubular member is manipulated until the distal end of the tubular member is disposed within the thoracic duct. Fluid is removed from the thoracic duct through the tubular member to a location exterior to the patient's body, and one or more organs are removed from the donor body. Optionally, one or more parameters within the thoracic duct or other parameters of the donor body may be monitored and fluid removal may be adjusted to reduce fluid accumulation within the one or more organs.

    Abstract: Devices, systems, and methods for treatment of an eye alter aspiration flow from the eye in response to an occlusion of the aspiration conduit pathway. Where aspiration is drawn from the eye using a volumetric pump, the pump can be reversed so as to induce fluid reflux from the aspiration conduit pathway into the eye to help clear the occlusion. The pump may vary the reverse flow in response to sensed aspiration pressure or the like, and the reverse flow may be halted before the pressure within the aspiration conduit pathway adjacent the eye significantly exceeds the irrigation fluid pressure and/or the pressure within the eye. Reflux may alternatively be generated by modulating a vent valve disposed between an irrigation conduit pathway and the aspiration conduit pathway.

The method and the device are combined with a method for detecting blood cells, red blood cells, haemoglobin and/or debris in liquid coming from a surgical site to provide an automatic control and rinsing system with clear vision in the viewing area of the operational site.

  • Publication number: 20140163455
    Abstract: A method of irrigating a surgical site and aspirating fluid from the surgical site. The method includes directing a fluid through an aspiration conduit in a phacoemulsification hand piece using a vacuum pressure created from a pump in the hand piece interfacing with the aspiration conduit and directing an irrigation fluid through an irrigation conduit in the hand piece using a pressure created from the pump interfacing with the irrigation conduit. The method also includes increasing an irrigation fluid flow through the irrigation conduit by activating the pump in the hand piece, detecting a pressure associated with a surgical site using a sensor, and controlling intraocular pressure (IOP) by adjusting the pump speed based on the detected pressure.

  • Patent number: 8721585
    Abstract: Systems and methods for integrating a continuous glucose sensor, including a receiver, a medicament delivery device, and optionally a single point glucose monitor are provided. Manual integrations provide for a physical association between the devices wherein a user (for example, patient or doctor) manually selects the amount, type, and/or time of delivery. Semi-automated integration of the devices includes integrations wherein an operable connection between the integrated components aids the user (for example, patient or doctor) in selecting, inputting, calculating, or validating the amount, type, or time of medicament delivery of glucose values, for example, by transmitting data to another component and thereby reducing the amount of user input required. Automated integration between the devices includes integrations wherein an operable connection between the integrated components provides for full control of the system without required user interaction.

  • Patent number: 8721594
    Abstract: A post-occlusion chamber collapse canceling system for a surgical apparatus that detects the breaking of occlusions by tissue fragments in the distal end of the aspiration path and produces a response consisting in a transitory blockage of the distal end the aspiration path to terminate the chamber collapse and a transitory venting of the aspiration line to relieve the vacuum, in a way that post-occlusion chamber collapses are cancelled.

  • Patent number: RE45315
    Abstract: A whole blood collection system includes an automated pump/control unit and an accompanying disposable blood set. When combined and connected to a source of anticoagulant, these elements allow automatic priming of the blood set with anticoagulant and automatic collection of anticoagulated blood product according to three different collection modes. The unit's pump and the blood set are specially designed to cooperate during the collection process to assure that the collected product has a precise blood to anticoagulant ratio. During the collection procedure, the pump/control unit automatically collects data relating to the procedure. Additional data specifically identifying components of the blood set, such as the blood collection bag, along with identification data on the donor's registration form may be scanned into the pump/controller unit by a scanner associated with the unit; this facilitates positive sample identification and tracking.
