| 20090157002 | CATHETER HAVING COMMUNICATING LUMENS - A catheter having a plurality of longitudinal lumens for removing biological, natural and/or man-made materials from cavities, ducts, vessels, or other locations in a patient's body. The multi-lumen catheter comprises a longitudinally-extending suction lumen with suction holes through which materials pass into the lumen in response to suction forces generated by a source of negative pressure coupled to a proximal end of the lumen. A longitudinally-extending vent lumen coupled to a source of at least neutral vent pressure through, for example, an opening to ambient air at the proximal end of the lumen, and preferably, through vent holes disposed along a length of the catheter. A dividing septum between the adjacent lumens has one or more ports fluidically coupling the lumens. The ratio of the area of the suction holes and ports is such that the suction force at unobstructed suction holes is maintained below a desired maximum force for a given negative pressure when none or more of the suctions holes are obstructed. When a suction hole obstruction occurs, fluid is drawn into the suction lumen through the communication port(s). This compensating fluid flow prevents the suction forces from exceeding a predetermined maximum value during use even when one or more suction holes become obstructed. This maximum force may be set, for example, to avoid hematoma, to permit repositioning of the catheter during use, etc. thereby allowing for continuous suction. | 2009-06-18 |

In one embodiment, the drive charges an accumulator that displaces the pulse effector during a period of low pump motor activity maximizing onboard battery life. In another embodiment, the drive is an actuator with an armature that displaces a plunger into the pulse chamber to form the pulse. The resultant pulses are of sufficient duration and pressure above working pressure to achieve occlusion prevention and remediation. | 2009-06-18 |

| 20090157020 | Film Formed from a Blend of Biodegradable Aliphatic-Aromatic Copolyesters - A film that is formed from a biodegradable polymer blend of different aliphatic-aromatic copolyesters is provided. More specifically, the blend contains a first copolyester formed from a terephthalic acid monomer. The use of a terephthalic acid monomer results in a polymer chain containing 1,4-(para-) terephthalate units linked in a generally linear configuration (e.g., ˜180°). The blend also contains a second aliphatic-aromatic copolyester formed from a phthalic acid and/or isophthalic acid monomer. The use of such a monomer results in a polymer chain containing 1,2-(ortho-) and/or 1,3-(meta-) linked units. The inclusion of 1,2-(ortho-) and/or 1,3-(meta-) linked units into the polymer backbone of the second copolyester introduces an angle or “kink” (e.g., ˜120° kink for a 1,3-linkage) into the otherwise linear polymer chain. The “kinks” in the second copolyester backbone reduce its melting point and degree of crystallinity, which have an influence on its physical properties (e.g., toughness, tensile strength, and crystallization rate). Thus, the physical properties of the second copolyester may differ substantially from those of the first copolyester. In this regard, the “kinked” second copolyester can provide flexibility for forming films with a wide range of properties that is superior to that which may be achieved using either of copolyesters alone. | 2009-06-18 |

Further, graphical elements sharing a single common color tone may create one or more of the illusions that may otherwise be enhanced by incorporating multiple color tones to the graphical elements creating the illusions. Exemplary consumer products include disposable diapers, feminine sanitary napkins, printed or electronic advertising media, and removable packaging enclosing articles prior to their use. | 2009-06-18 |
| 20090157022 | ABSORBENT ARTICLES HAVING A WETNESS INDICATOR - Absorbent articles including a wetness indicator are generally described. The wetness indicator of the present invention is configured to expand toward the skin of the wearer (i.e., in the z-direction of the absorbent article perpendicular to the plane of the absorbent article) upon contact with a liquid. However, the expansion of the wetness indicator is substantially limited to the z-direction. That is, the wetness indicator does not substantially expand in any direction parallel with the plane of the article (i.e., the x- and y-directions). As such, the wetness indicator does not significantly interfere with the absorbent capabilities of the absorbent article. Thus, the wetness indicator can be included within conventional absorbent articles without significantly sacrificing the absorbency characteristics of the article. | 2009-06-18 |
