Patent number: 11291755Abstract: Exemplary embodiments described herein are directed to arteriovenous (AV) access catheters with inline needles that are protectable by sliding displacement of the catheter, and to methods of performing hemodialysis using said AV catheters. Extension (sliding) of the catheter portion of an exemplary device relative to a needle portion, after the needle of the needle portion has been used to access a patient fistula/graft, allows the catheter to cover the needle tip, thereby minimizing or eliminating the possibility that the needle may damage the fistula/graft. Because the needle still remains largely within the catheter, there is no risk of catheter collapse, kinking, etc., which could compromise blood flow during a hemodialysis procedure.Type: GrantFiled: June 19, 2018Date of Patent: April 5, 2022Assignee: Aadi Innovations LLCInventor: Aaditya Shidham

Patent number: 11253401Abstract: A pump generates a vacuum at a wound site via first tubing. A negative pressure circuit is defined by a canister, the first tubing and the wound site. A controller of a therapy device operates the pump to apply a first negative pressure to the entirety of the negative pressure circuit, following which ambient air is allowed to flow into the negative pressure circuit. The controller also operates the pump to apply a second negative pressure to a selected portion of the negative pressure circuit exclusive of the wound site, following which ambient air is allowed to flow into the selected portion. A quantity of fluid to be delivered to the wound site via a second tubing is determined by comparing measured parameters related to the flow of air into the negative pressure circuit to parameters measured with respect to the flow of air into the selected portion.Type: GrantFiled: March 26, 2019Date of Patent: February 22, 2022Assignee: KCI Licensing, Inc.Inventors: Benjamin A.

Patent number: 11246971Abstract: A method and a system are provided for detecting a condition indicative of a dislodged needle in a hemodialysis procedure. A venous return pressure for a patient undergoing dialysis is measured. The venous return pressure is analyzed via a controller, and an intravascular blood pressure in proximity to a location of needle insertion into the patient is derived. A lower limit is calculated as a function of the intravascular blood pressure via the controller. An average of the venous return pressure is calculated via the controller during a predetermined time window. The average is compared to the lower limit via the controller, and if the average is within a specified range of the lower limit, the controller determines that a condition indicative of a dislodged needle is present.Type: GrantFiled: September 19, 2017Date of Patent: February 15, 2022Assignee: Henry Ford Health SystemInventors: Stanley Frinak, Gerard Zasuwa, Jerry Yee, Anatole Besarab
