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.

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.

Patent number: 8696640Abstract: A device for treating a snake bite wound that utilizes a hypodermic tube with a curvature that is similar to a typical snake fang whereby the hypodermic tube on one end comprises a smooth bulbous tip with at least one opening and a vacuum source is attached to the other end of the hypodermic tube. The tip is inserted into a snake bite wound, and due to the curved shape of the hypodermic tube, the tip and the tube then follow the curved shape of the snake bite wound without damaging any of the tissue surrounding the snake bite canal. The vacuum source then extracts any venom that is present from the wound. The device also enables medicine to be injected into the wounded area to treat the wound.Type: GrantFiled: January 10, 2011Date of Patent: April 15, 2014Inventor: Russell Churchill

Patent number: 8679052Abstract: The invention provides an improved microdialysis method for determining the free concentration of an agent or drug (defined as the concentration of agent that is dissolved and free to diffuse, and not undissolved or precipitated, complexed, bound, included in micelles or microemulsions, etc.). In addition. the invention provides such a method under conditions in which the properties of the microdialysis probe may change. Further, the invention provides a method for determining the permeability of a diffusible agent through the probe wall. The invention also provides a method for determining the rate of change of concentration of an agent in a medium.Type: GrantFiled: August 21, 2010Date of Patent: March 25, 2014Inventor: Robert Arthur Bellantone

Patent number: 8657777Abstract: Catheters including guidewire tubes having a limited length and methods of using the catheters are described. The catheters may be delivered over guidewires in procedures that are commonly referred to as rapid-exchange delivery. In some embodiments, the catheters may be miniature flexible thrombectomy catheters that may be used to remove thrombus or other unwanted material from a body blood vessel or other small regions of body cavities in which the distal portion of the catheter has smaller external dimensions than the larger proximal portion.Type: GrantFiled: January 14, 2013Date of Patent: February 25, 2014Assignee: Bayer Medical Care Inc.Inventors: Debra M. Kozak, Michael J. Bonnette, Eric J. Thor, David B. Morris, John L. Teschendorf, Douglas J. Ball, Michael Schrom, Stephen E. Weisel

Patent number: 8652088Abstract: Very accurate measurements of mass transfer can be made rapidly by permitting diffusion of an agent desired to be measured into or out of a small, very precisely known volume of a microdialysis probe, then rapidly pumping or flushing (“pulsing”) the probe with a known volume of fluid as a single pulse. The diffusion and pulsing may be repeated. The method, hereinafter called pulsatile microdialysis (PMD) to distinguish it from prior art continuous flow microdialysis, is useful for measurements in a number of processes, including protein binding, adsorption to binding agents such as activated charcoal, release from microemulsion drug delivery systems, determination of drug diffusion coefficients and concentrations, and for various other purposes. The method is based on mathematical manipulation of Fick's Laws. Resulting equations were verified against experimental data using methazolamide, warfarin and benzocaine as test drugs.Type: GrantFiled: September 4, 2012Date of Patent: February 18, 2014Inventor: Robert A. Bellantone

Patent number: 8652117Abstract: Vaccine is administered into a nose. A pharmaceutically-acceptable aqueous saline solution carrier comprising from 0.5% to 1.9% salt is provided in a nasal device. The saline solution is administered into a first nasal cavity to rinse the first nasal cavity. The saline solution is added to the first nasal cavity until the saline solution flows via a posterior nasal aperture into a second nasal cavity. A vaccine is then administered into the first nasal cavity.Type: GrantFiled: October 29, 2008Date of Patent: February 18, 2014Inventors: Peter Ahnblad, Robert Halasz, Susanne Ahnblad Lagerqvist

Patent number: 8647315Abstract: A medical canister connector is presented for connecting to a medical canister, which has a patient port and a reduced-pressure port. The medical canister connector includes a first connection member that is coupled to a patient-port-attachment member, which is for coupling to a patient port on a medical canister and has a patient-port opening with a first longitudinal axis. The medical canister connector also includes a second connection member coupled to a reduced-pressure-port-attachment member, which is for coupling to a reduced-pressure port on the medical canister and has a reduced-pressure-port opening with a second longitudinal axis. A spacing member or pressure transport member may be used to couple the first connection member to the second connection member. The spacing member or transport member flexes and twists during connection. The medical canister connector may also help organize one or more pressure-sensing conduits. Methods are also presented.Type: GrantFiled: April 18, 2012Date of Patent: February 11, 2014Assignee: KCI Licensing, Inc.Inventors: Tyler Simmons, Alexander Sammons, Kenneth Knowles
