Patent number: 9668638Abstract: A system for registering images is provided. The system includes a first imaging device having an imager positioned at a distal end thereof. The first image device is configured to produce a first image of a body cavity. The system includes an imaging system having a second imaging device having an imager positioned at a distal end thereof and configured to be positioned approximate to said imager of said first imaging device within said body cavity and configured to produce a second image. An elongated member having an outer surface is molded to include imaging markers such that said imaging markers are embedded within the outer surface. At least one of the image markers is configured to produce registration information in the first image and the second image.Type: GrantFiled: February 4, 2014Date of Patent: June 6, 2017Assignee: Ninepoint Medical Inc.Inventors: Shekhar Nimkar, David Vader, Jim Houskeeper

Patent number: 9662430Abstract: The invention relates to a device and a method for conveying a fluid to a filter unit of a medical treatment apparatus, in particular for conveying a dialysing fluid to a treatment unit, in particular a dialyser or filter of an extracorporeal blood treatment apparatus. The device comprises a balancing unit and a recirculation unit, which comprises one or more chambers. With the balancing unit, it is possible to supply fresh fluid continuously to the recirculation circuit and to discharge used fluid from the recirculation circuit. The supply and discharge of fresh and used dialysing fluid can take place at a flow rate other than the flow rate at which the fluid circulates in the recirculation circuit via the filter unit.Type: GrantFiled: April 13, 2012Date of Patent: May 30, 2017Assignee: Fresenius Medical Care Deutschland GmbHInventors: Stefan Kreber, Manfred Weis

Patent number: 9656043Abstract: A multilumen catheter with an inflow or an outflow lumen having at least two tube extensions extending from the distal end of the catheter that open into the inflow or outflow lumen. The catheter is useful in the extracorporeal treatment of blood, such as hemodialysis, hemofiltration or apheresis. A device to selectively test each of the two tube extensions for occlusion.Type: GrantFiled: December 22, 2011Date of Patent: May 23, 2017Assignee: Cook Medical Technologies LLCInventors: Neha S. Bhagchandani, Ryan Nowicki, Michael R. Kurrus

Patent number: 9642779Abstract: There is provided a computer-implemented method for calculating a gastric emptying rate from a stomach lumen into a small intestine of a patient, comprising: using at least one processor for executing the following during an enteral tube feeding of a stomach of the patient by a feeding mechanism: analyzing outputs of at least one stomach sensor located within the stomach for detecting a stop feeding condition; pausing the enteral tube feeding in response to a detection of the stop feeding condition; after a predefined period of time, restarting the enteral tube feeding until the stop condition is redetected by an analysis of said outputs; calculating a gastric emptying rate based on an amount of feeding content delivered during a period between the restarting and the redetection; and instructing the feeding mechanism to adapt a feeding rate of the enteral tube feeding according to the gastric emptying rate.Type: GrantFiled: November 26, 2015Date of Patent: May 9, 2017Assignee: ART Healthcare Ltd.Inventors: Liron Elia, Gavriel J.

Patent number: 9603989Abstract: Methods are provided for anticoagulating blood. Whole blood is drawn from a donor into a system at a draw flow rate. Anticoagulant from an anticoagulant source is pumped into the system at an anticoagulant flow rate to mix with the blood. The anticoagulated blood may be subsequently processed in any of a number of known ways, including separating it and removing at least a portion of one of the components of the blood. Thereafter, at least a portion of the remaining blood may be returned to the donor. The anticoagulant flow rate is independent of the draw flow rate and can be based on a number of factors, including the weight of the donor and the rate at which the donor can metabolize the anticoagulant.Type: GrantFiled: August 24, 2010Date of Patent: March 28, 2017Assignee: Fenwal, Inc.Inventor: Richard I.
