20100228232 | Catheter flushing assembly - An assembly for flushing at least the primary flow lines associated with a catheter, such as an intravascular catheter, comprising first and second flush ports connected in fluid communicating relation with a different one of said primary flow lines. A primary flow restrictor assembly includes two safety flow restrictors, disposed at a main hub of the catheter and the primary flow lines, and being structured to regulate fluid flow between the primary flow lines and the catheter. A flushing orientation is established when the two safety flow restrictors are concurrently disposed in a closed position, thereby establishing fluid flow between the primary flow lines and corresponding ones of the first and second flush ports, wherein one-way valves associated with each of the flush ports facilitate a concurrent path of flushing fluid from said primary flow lines and towards, out and through the first and second flush ports, to the external environment. Consequently, the flushing assembly of the present invention can prevent the introduction of flushing fluid, along with any bacteria or other collection of material carried by it, into a patient's bloodstream. | 09-09-2010 |

Another lock solution provided by the invention includes citrate, a paraben and a photo-oxidant, such as, for example, methylene blue. | 09-23-2010 |
20100326911 | DIALYSIS SYSTEM - A dialysate fluid circulation apparatus includes a dialyzer, a first housing and a second housing. The first housing contains material capable of releasing sodium into dialysate fluid flowing through the first housing. The second housing contains material capable of binding sodium ions from dialysate fluid flowing through the second housing. Hydraulic conduit sections are configured to extend between the dialyzer, the first housing, and the second housing to connect the dialyzer with the housings in a primary flow path for dialysate fluid to flow from the dialyzer to the first housing, from the first housing to the second housing, and from the second housing back to the dialyzer. | 12-30-2010 |
20110313401 | INDWELLING CATHETER WITH ANTI-CLOTTING FEATURES - A catheter for providing blood flow includes first and second lumen parts having a distal portion with at least one port for delivering and receiving flow from a patient and a non-linear profile along the distal portion. | 12-22-2011 |
20120233931 | Roof Deflector System - A system for separating water from debris. A gutter cover is secured to a gutter and extends to engage the top of the roof adjacent the gutter along a contact line. The gutter cover may have a perforate surface comprising closely spaced and normally water impervious holes through the gutter cover such that water does not flow through the holes unless the water is forced through the holes or attracted through the holes. The line of contact forms an imperfect junction between the edge of the gutter cover and the roof so that water flows through the contact line and beneath the gutter cover. | 09-20-2012 |
