| 20160106916 | Reservoir for Collection and Reuse of Diverted Medium - A system and method for collection and re-use of a fluid medium derived from the diversion of at least some of an injection of the medium to a selected site within a patient's body are described. The system includes a sterile medium container, a flow diverter assembly disposed in a fluid medium flow path between an injection syringe and a medium delivery catheter, and a diversion reservoir having a reservoir chamber for receiving the diverted portion of the fluid medium from the flow diverter assembly and a fluid coupling to the sterile medium container. The flow diverter assembly is configured to divert at least a portion of a fluid medium injection from the medium flow path between the syringe and the delivery catheter during injection. The diversion reservoir is configured so as to preferentially allow re-use of the diverted medium in the reservoir chamber prior to allowing use of the medium in the sterile medium container. | 04-21-2016 |
| 20160143952 | ADIPOSE-DERIVED REGENERATIVE CELLS FOR TREATING LIVER INJURY - Cells present in processed lipoaspirate tissue are used to treat patients. Methods of treating patients include processing adipose tissue to deliver a concentrated amount of stem cells obtained from the adipose tissue to a patient. The methods may be practiced in a closed system so that the stem cells are not exposed to an external environment prior to being administered to a patient. Compositions that are administered to a patient include a mixture of adipose tissue and stem cells so that the composition has a higher concentration of stem cells than when the adipose tissue was removed from the patient. | 05-26-2016 |
| 20160144097 | FLUID CONVEYANCE SAFETY DEVICES, METHODS, AND SYSTEMS - The disclosed subject matter includes a structure and method for making a dual-lumen needle from single lumen needles to take advantage of the much higher economies of scale. Variations include two needles joined by a flow junction and one needle and a single cannula joined by a flow junction. In addition disclosed are methods of using a dual-lumen needle in a two needle access for blood treatment is disclosed in which at least venous flow is provided through a dual-lumen needle with arterial flow just sufficient to provide air infiltration detection in the event of withdrawal of the dual-lumen needle. | 05-26-2016 |
| 20160158423 | DEVICES AND METHODS FOR CLEANING CONTAMINATED BODY CAVITIES - An apparatus includes a housing, a first cannula, and a second cannula. The housing defines an inner volume having a first portion in fluid communication with a first set of openings, and a second portion in fluid communication with a second set of openings and fluidically isolated from the first portion. The first cannula has a proximal end portion fluidically couplable to a vacuum source and a distal end portion coupled to the housing such that the first portion of the inner volume and a lumen defined by the first cannula fluidically couple the first openings to the vacuum source. The second cannula has a proximal end portion fluidically couplable to a fluid source and a distal end portion coupled to the housing such that the second portion of the inner volume and a lumen defined by the second cannula fluidically couple the second openings to the fluid source. | 06-09-2016 |

| 20160184503 | DIALYSIS SYSTEM AND METHOD FOR PUMPING AND VALVING ACCORDING TO FLOW SCHEDULE - A dialysis system includes a disposable cassette including a flexible sheet and a plurality of dialysis fluid pathways, a plurality of actuators operable with the flexible sheet to direct dialysis fluid through the plurality of dialysis fluid pathways, and a controller configured to (i) determine at least one limitation of the plurality of dialysis fluid pathways, (ii) generate a flow schedule indicating how dialysis fluid should be directed through the plurality of dialysis fluid pathways in accordance with the at least one limitation, and (iii) control the plurality of actuators so that dialysis fluid is pumped through the plurality of dialysis fluid pathways according to the flow schedule. | 06-30-2016 |
| 20160184505 | PATIENT WARMING SYSTEM - A method of warming a patient during a surgical procedure may involve catheterizing the patient's bladder with a catheter that permits simultaneous flows into and out of the bladder. Fluid may be warmed and pumped into the bladder through the catheter, via a supply path, and simultaneously drained out of the bladder, via a return path. In steady state, there may exist a continuous air-fluid interface along one or more sections of a drain line of the return path having a negative slope with respect to the earth's gravitational field. | 06-30-2016 |

| 20160375190 | PERITONEAL DIALYSIS SYSTEMS AND METHODS - Described are peritoneal dialysis systems and methods that involve the use of first and second stage filtration of a used dialysate withdrawn from the peritoneal space of a patient. The first filtration stage forms a first retentate containing an osmotic agent and a first permeate containing water and nitrogen-containing waste products of the patient. The second filtration stage acts on the first permeate to form a second retentate containing nitrogen-containing waste products of the patient and a second permeate containing water. At least some of the water from the second permeate is combined with the first retentate to form a regenerated peritoneal dialysis medium containing an amount of the osmotic agent. The regenerated peritoneal dialysis medium can be returned to the peritoneal space of the patient. | 12-29-2016 |
| 20160375221 | FLUID EXCHANGE CATHETER AND PROCESS FOR UNBLOCKING A FLUID EXCHANGE CATHETER - According to the invention, a fluid exchange catheter is provided, which catheter has a proximal end and a distal end, and comprises an obligatory lumen having a proximal end and a distal end, the distal end of the obligatory lumen having a closed shape, wherein a lumen wall of the obligatory lumen forms a distal wall portion at the distal end of the obligatory lumen, the distal wall portion comprising at least one lumen opening in the lumen wall. Furthermore, the catheter comprises at least one additional lumen having a proximal end and a distal end, the distal end being arranged inside the obligatory lumen remote from the distal end of the obligatory lumen such that fluid exiting the at least one additional lumen flows inside the distal end of the obligatory lumen. Here, the distal wall portion exhibits expansibility in at least an area surrounding the at least one lumen opening in order to provide an unblocking function for removing blockage of the catheter, any lumen can be adapted for fluid infusion and/or fluid aspiration, and an unblocking of the catheter is effected by altering the width of the at least one lumen opening by changing the infusion and/or aspiration fluid pressure of the catheter, the infusion and/or aspiration fluid pressure being different from an outer pressure acting on the outside of the distal wall portion of the obligatory lumen. | 12-29-2016 |
