Patent number: 9199060Abstract: A non-bladder invasive urethral catheter system with a urethral balloon element for relieving urinary incontinence. The catheter system is more convenient and less intrusive compared to bladder catheters and permits the catheter to remain in the urethra during urination. The catheter system blocks urine flow and leakage in the urethra by means of the urethral balloon element while inserted within the urethra. Two or more different urethral catheters are utilized that are differentiated by the positioning of a urethral balloon element on the elongated body of the urethral catheter. Through the placement of the urethral balloon element in different positions in the urethra with the different catheters, the trauma produced by a urethral balloon element to a particular area of the urethra is reduced or eliminated, allowing long term use of a catheter in the urethra.Type: GrantFiled: August 30, 2014Date of Patent: December 1, 2015Inventor: Henry Allison Barnett

Patent number: 9186450Abstract: A method and apparatus for priming an extracorporeal blood circuit, in which the patient end of an arterial line (79) is connected to a first discharge port (61), and the patient end of a venous line (87) is connected to a second discharge port (62). The two discharge ports are connected to a used dialysate line which connects a dialyzer (33) to a drain. The arterial and venous lines are filled with a priming fluid, while the air contained in the arterial and venous lines is evacuated partly through the first discharge port and partly through the second discharge port. Two check valves (65, 66) prevent flow from the used dialysate line towards the two discharge ports. The invention reduces the risk of errors on the part of an operator readying the priming configuration, as well as the risk of contamination of the extracorporeal circuit during the priming phase.Type: GrantFiled: August 10, 2013Date of Patent: November 17, 2015Assignee: Gambro Lundia ABInventors: Massimo Fava, Mauro Suffritti, Alessandro Scaglione

Patent number: 9144646Abstract: In some aspects, a vial spiking device includes a base, a spike extending from the base, and a side wall extending from the base and substantially surrounding the spike. The base and the side wall partially define a recess to receive a portion of a vial. Resilient fingers extend inwardly from the side wall into the recess. The fingers are spaced circumferentially around the side wall and are configured so that as the vial is inserted into the recess, the fingers deflect toward the side wall and allow the portion of the vial to move beyond the fingers. The fingers rebound into the recess after the portion of the vial has moved beyond the fingers. The side wall forces the portion of the vial away from the base and into contact with the fingers after the fingers have rebounded into the recess.Type: GrantFiled: March 13, 2013Date of Patent: September 29, 2015Assignee: Fresenius Medical Care Holdings, Inc.Inventors: John A. Barron, III, Chad Unger, Douglas Mark Zatezalo, Michael John Zang

Patent number: 9138568Abstract: An apparatus capable of generating flow in cerebrospinal fluid (CSF) shunt systems by vibrating the shunt, tubing or shunt valve dome, or applying cyclical pressure to the various parts of the shunt system. A method of generating flow and method of using the apparatus in shunt patency assessment, for example, hydraulic resistance assessment, is also disclosed. The apparatus allows, in conjunction with a thermal dilution method or radionuclide method, a quick CSF shunt patency assessment based upon CSF shunt resistance and not upon CSF flow or intracranial pressure (ICP) separately. This provides a more objective measure of shunt obstruction compared to other methods. Furthermore, the apparatus can be used to enhance flow in shunts, identify partial occlusion before symptoms occur, differentiate between patent, partially-occluded and occluded shunts. The apparatus can be used to generate flow in shunts if there is a need to lower ICP or move drugs administered via an injection chamber or a shunt dome.Type: GrantFiled: May 19, 2011Date of Patent: September 22, 2015Assignees: ShuntCheck, Inc., The Children's Medical Center CorporationInventors: Marek Swoboda, Matias Gabriel Hochman, Mark Evan Mattiucci, Frederick J.

Patent number: 9138522Abstract: Blood or other fluids can be caused to interact with a gas by providing a plurality of fluid flow channels that are surrounded by nanotubes, each of the channels having an inflow end and an outflow end, wherein each of the channels is wide enough for the blood to flow through, and wherein the nanotubes are spaced close enough to each other to retain the fluid within the channels when the blood is flowing through the channels. The fluid is then passed through the through the channels while a gas is passed through the spaces between the nanotubes outside the fluid flow channels. This permits the gas to interact with the fluid in the channels.Type: GrantFiled: July 15, 2014Date of Patent: September 22, 2015Inventor: Yoram Palti

Patent number: 9119578Abstract: In some embodiments, the present invention generally relates to the separation of blood within a device to form plasma or serum. In some embodiments, the present invention generally relates to the removal of fluids, such as blood, contained within a device. For example, a device may be applied to the skin of a subject to receive blood from the subject and pass the blood through a separation membrane, which separates the blood into plasma and a portion concentrated in blood cells. As another example, blood or plasma may be allowed to clot within the device and serum (the unclotted portion of the blood) may be withdrawn from the device. The device may contain, in some cases, a vacuum source such as a pre-packaged vacuum to facilitate receiving of blood and/or passage of the blood through the separation membrane to produce plasma or serum.Type: GrantFiled: April 26, 2012Date of Patent: September 1, 2015Assignee: Seventh Sense Biosystems, Inc.Inventors: Ramin Haghgooie, Donald E.
