Patent number: 9314590Abstract: The present invention relates to apparatus for retroperfusion of tissues and organs. The apparatus comprises a catheter with a proximal end for engaging a supply of the fluid medium, and a distal end having an expandable-contractible chamber for installation into suitable vessels or organs. The expandable-contractible chamber comprises a conduit element having a fluid-filled hollow wall defining a lumen. The conduit element has a first deformable inner-facing section approximate a proximal end of the conduit and a second deformable inner-facing section approximate a distal end of the conduit element. Controlled application of a pressure at a proximal end of the conduit element causes deformation of the conduit into the lumen at its distal end thereby occluding the flow of fluid medium through the catheter. Controlled release of the pressure releases deformation of the fluid-filled conduit at its distal end thereby unblocking the flow of the fluid medium through the catheter.Type: GrantFiled: June 14, 2011Date of Patent: April 19, 2016Assignee: University of ManitobaInventors: Li Zhang, Farrukh Hussain

Patent number: 9302058Abstract: A system for tracing tubing which forms a conduit from a source of infusion liquid to a patient by way of an infusion pump has a vibration generator manually operable by a user to generate vibrations at an origin location along the tubing, wherein the vibrations are propagated by the tubing and have a vibration signature. A vibration sensor arranged at a destination location along the tubing receives the vibrations and generates a digital vibration signal. Signal processing circuitry connected to the vibration sensor processes and evaluates the digital vibration signal to determine a trace status of the tubing between the vibration generator and the vibration sensor. An indicator connected to the signal processing circuitry provides an indication of the determined trace status. Trace status possibilities include clear, cross-over, and null. A likely number of cross-overs may also be indicated.Type: GrantFiled: March 15, 2013Date of Patent: April 5, 2016Assignee: CURLIN MEDICAL INC.Inventor: Sreelal Chandrasenan

Patent number: 8876753Abstract: A peritoneal-based artificial kidney processes peritoneal fluid without need for additional fluids. Spent dialysate is separated into a protein-rich stream and a protein-free stream. The protein-rich stream is regenerated using a sorbent assembly, and its protein composition can be modified by removal of selected protein(s). Alternatively, the spent dialysate is first processed in a sorbent assembly and then separated into the protein-rich and protein-free streams. Immobilization of urease allows more protein rich fluid to be regenerated and re-circulated into the peritoneal cavity for toxin removal and allows practicable development of portable and wearable artificial kidneys.Type: GrantFiled: April 27, 2012Date of Patent: November 4, 2014Assignees: The Regents of the University of California, The United States of America as represented by the Department of Veterans Affairs, Office of the General CounselInventors: Martin Roberts, David B.
