Abstract: Various embodiments of a fluid collection system having multiple storage chambers are disclosed. In an exemplary embodiment, the system may include a first chamber in fluid communication with a suction source and a second chamber in fluid communication with the first chamber. The second chamber may have a volume less than a volume of the first chamber. The second chamber may also comprise an inlet port for connecting to an external tube. The system may be configured to selectively drain liquid from the second chamber into the first chamber.

Abstract: The invention described herein relates to an improved device for paracentesis procedures, such as thoracentesis. The device comprises a cannula assembly, valve assembly, and catheter assembly, wherein the cannula assembly is removably attached to the valve assembly, and the valve assembly is removably attached to the catheter assembly. The device can comprise an externally viewable indicator revealing the relative positions of the cannula assembly components. The device can further comprise a locking mechanism which controls the movement between cannula assembly components and is activated and deactivated by the coupling of the cannula assembly to the valve assembly. The device improves the precision and safety of its handling, and offers the practitioner several aspiration alternatives while maintaining separation of the internal and external patient environments.

Abstract: A packaging system in accordance with the principles of the present invention includes a sterilization pouch. The pouch includes a posterior portion attached to an anterior portion along three edges. The two portions define the pouch. The top part of the pouch is inverted so that the inside part of the pouch is facing outward and forms a cuff around the pouch. An integral internal sterilization indicator is further provided. The integral indicator comprises a sterilizing agent sensitive substance. The sterilizing agent sensitive substance can be an indicator ink printed as an ink line on the interior of the sterilization pouch below the cuff. Thus, the indicator becomes visible during aseptic delivery of the packaged article to provide a clear indication as to whether or not adequate conditions for sterilization have been achieved. In a further embodiment, the indicator ink line repeats as a pattern throughout the interior of the sterilization pouch.

Abstract: A flexible wrist-type element and methods of operation thereof, including variations having an angularly moveable hub housing a rotatable and operable end effector driven via a drive train having one or more universal-type joints and/or other flexible couplings moveable via an input mechanism within a housing.
Abstract: A method of forming a fenestrated extremity surgical drape includes providing improved seal integrity to reduce the occurrence of pathogenic contamination at the surgical site via migration through the seal. The seal has a non-linear configuration to eliminate uneven stress concentrations commonly located at the corners of rectilinear seals. An elastomeric apertured panel can be disposed between a film panel and a fiber/film laminate panel. These layers can be joined by a heat sealing operation along two spaced apart concentric seal locations ringing the aperture and a fenestration in the laminate panel. The assembly can then be affixed by adhering the underside(s) of one or more panels to a base drape, which has an opening aligned with the aperture and fenestration.

Abstract: An autofeed mechanism for controlling the flow and level of a fluid. The mechanism includes a body with an inlet chamber and a float chamber. A seat permits fluid communication between the two chambers. A float and a ball cooperate to permit, or deny, access to the seat. Fluid first enters the inlet and fills the chamber and then enters the float chamber by passing through the seat and exiting via the exit. Initially, the weight of the float keeps the ball away from the seat, but eventually the fluid level rises high enough that the action of the float on the ball decreases to a level that is overcome by the buoyant force of the ball and other fluidic forces resulting in the ball moving away from the ball support. Finally, the ball rises enough to seal against the seat thus stopping the flow of fluid.
Abstract: There is provided an improved sterilization wrap and a method for using the improved sterilization wrap to sterilize an article. The wrap is made of at least a first panel of sterilization material and includes an additional panel of material. The first panel is multi-layered and includes at least one pathogen filtration layer. The first panel is rectangular and has an outer periphery and a central portion. The outer periphery includes first, second, third and fourth edges. The additional panel of material is bonded to the first panel, approximately at a forty-five degree angle to the first panel, with a substantial portion of the additional panel being adjacent to the central portion of the first panel. The perimeter of the additional panel is smaller than the perimeter of the first panel. Portions of the additional panel are bonded to the first panel along the first, second, third and fourth edges of the first panel.
