20140360541 | Covering System - A system is provided for protective elements that include, but is not limited to, an umbrella having a complete double canopy with pleats, a medially expanding frame, and a moisture mitigation vessel. The frame's linkage system and expanding double canopy enable their combined covering structure to take a downwardly concave form when fully deployed. Rounded outer frame edges provide enhanced safety. When retracted around the umbrella's stick, frame and canopy assume the form of a three dimensional envelope tapered up and down from its mid-section, thereby concentrated at top and bottom by the stick. This configuration provides canopy and frame with improved ability to move in and out of the invention's stick mounted moisture mitigation vessel. With an internal liner of wicking material and multiple surface apertures, the vessel encourages controlled release of evaporated moisture from the enclosed canopy. | 12-11-2014 |

The frame's rounded outer edges provide enhanced safety. When retracted around the umbrella's stick, the frame and canopy assume the form of a three dimensional envelope tapered vertically from its midsection, concentrated at top and bottom. Dedicated mechanisms are also provided for deploying an insect interdicting canopeum. Furthermore, a mitigation vessel provides protective storage for frame, canopy, and canopeum elements. With an internal liner of wicking material and multiple surface apertures; the system encourages controlled release of evaporated moisture from stowed elements. The invention's combination of features including capability for expedient transport from place to place, plus seasonal storage practicality, makes this product an appealing enhancement to outdoor living experiences. | 12-11-2014 |

20140276470 | Dialysis Catheters with Fluoropolymer Additives - A venous access catheter shaft and method of using and manufacturing such a catheter is provided. In one aspect of the invention, a catheter is provided comprising a base polymer having a Shore A durometer of 85A or lower, with 2.0% percent by weight of surface modifier, and a radiopaque filler comprising between 20-40 percentage by weight. In another aspect of the invention, a method reducing thrombus accumulation on a venous access catheter is provided wherein the catheter surface's resistance to thrombus formation is enhanced during indwell time by lowering the durometer rating of the base polymer of the catheter without increasing the amount of surface modifier additive. In another aspect of the invention, a method of manufacturing a catheter shaft is provided, wherein the shaft is formed comprising a base polymer having a Shore A durometer of 85A or lower, with 2.0% percent by weight of surface modifier, and a radiopaque filler comprising 30% by weight barium sulfate, and optionally a colorant of 0.2% weight. | 09-18-2014 |

20090157051 | Catheter with open faced end portion - A vascular access catheter that has a substantially distal end portion that has a distal tip. The distal end portion has a sloped face in the distal portion of the catheter, an outflow lumen aperture, and a second inflow lumen aperture. The outflow lumen aperture is substantially completely open in the sloped face and exits the distal portion adjacent the distal tip. The catheter has a guidewire lumen that is located at least in the region of the distal portion of the catheter and is capable of receiving a guidewire. The guidewire lumen has a proximal aperture and a distal aperture that extends distally of the outflow lumen aperture. The guidewire distal aperture exits at the distal most edge of the distal end portion. The guidewire lumen may extend a partial length of the catheter or substantially the entire length of the catheter. The catheter distal portion may be substantially straight or curved. | 06-18-2009 |

20120316546 | Device and Method for Endovascular Treatment for Causing Closure of a Blood Vessel - An endovascular treatment method for causing closure of a blood vessel is provided. The method includes inserting into a blood vessel an optical fiber having a core through which a laser light travels and a spacer sleeve arranged around a distal portion of the core. A distal end of the core defines an enlarged light emitting face, which advantageously provides substantially lower power density while providing the same amount of total energy during a treatment session. After the insertion, laser light is applied through the light emitting face while the inserted optical fiber and spacer sleeve are longitudinally moved. The spacer sleeve positions the light emitting face away from an inner wall of the blood vessel and application of the laser light causes closure of the blood vessel. | 12-13-2012 |
20150025512 | DEVICE AND METHOD FOR ENDOVASCULAR TREATMENT FOR CAUSING CLOSURE OF A BLOOD VESSEL - An endovascular laser treatment device for causing closure of a blood vessel uses an optical fiber adapted to be inserted into a blood vessel. An inner sleeve is arranged around a distal portion of the optical fiber core such that both distal ends of the inner sleeve and the optical fiber core form an enlarged light emitting face. The enlarged emitting face provides substantially lower power density while providing the same amount of total energy during a treatment session. An outer sleeve arranged around the inner sleeve acts as a spacer to position the light emitting face away from an inner wall of the blood vessel. The enlarged light emitting face and the outer sleeve acting as a spacer reduces the possibility of thermal run-away and device damage, and reduce the possibility of vessel perforations, leading to less bruising, post-operative pain and other clinical complications. In yet another aspect of the present invention, a spacer comprises an inner sleeve and an outer sleeve both arranged around a distal portion of the core to prevent the laser light from traveling laterally and to position the light emitting face away from an inner wall of the vessel. The inner sleeve can be a heat resistive material such as ceramic and the outer sleeve can be, for example, a metallic sleeve to provide structural integrity and strength to the distal section of the treatment device. | 01-22-2015 |
