摘要:
The invention provides a sterilizable pouch having at least one wall formed of a flexible film and including an opening formed therein for providing communication to an interior space of the package. A breathable material is disposed on an outer surface of the wall covering the opening. The breathable material is joined to the outer surface of the wall with a continuous heat seal. The flexible film forming the wall comprises a multilayer film having a peel feature that permits the breathable material to be peelably removed from the surface of the pouch.

A thermally shrinkable wrapper, in particular for use in sterilization processes, includes a first layer of a thermally shrinkable film in the form of a continuous band having a pre-determined width and at least approximately parallel longitudinal edges that define a longitudinal direction of the wrapper. A second layer of a thermally shrinkable film in the form of a continuous band having a pre-determined width and at least approximately parallel longitudinal edges, is placed over said first layer so that the longitudinal edges of the first and said second layer are at least approximately aligned with respect to each other. A pair of bearing bands provided by a thermally non-shrinkable material are embedded and welded between the first layer and the second layer in the area of their aligned longitudinal edges.

Packaging for prosthetic heart valves including an assembly for stabilizing dry prosthetic tissue implants such as heart valves during storage. The packaging assembly includes a primary sterile barrier that permits gas sterilization of the tissue implant, and a secondary sterile barrier that also prevents oxidation of the implant during long-term storage. Tissue heart valves may be placed or suspended within a cavity of an inner rigid tray with a gas-permeable lid sealed thereon, and a cap placed over the cavity to limit movement of the valve therein. The inner tray is placed within an outer sterile barrier, such as another rigid tray or a flexible pouch, and the assembly is then sterilized. The outer sterile barrier may include a double seal so that a first gas-permeable seal can be closed for sterilization, after which a second gas-impermeable seal can be closed to seal out any further oxygen contact with the tissue implant. Alternatively, the inner tray may be placed within a sterile pouch and the assembly gas-sterilized, and then the entire assembly is placed within another pouch that provides an impermeable barrier to the surrounding atmosphere to prevent oxidation of the tissue implant.

The present invention concerns a flexible container (1) for transporting and dispensing one or a plurality of liquid products, comprising: - at least two stacked flexible walls (2) linked together at least at the periphery thereof, said walls (2) linked in this way defining an internal volume (3) capable of receiving one or a plurality of liquid products having biocide properties, - an upper portion (4) and a lower portion (5), said internal volume (3) being positioned between said upper portion (4) and lower portion (5) of said container, - at least one member for accessing said internal volume (3) capable of bringing the internal volume into fluid communication with the outside of the container, - a readable data carrier (10), characterised in that it further comprises a ventilation means for ventilating said container (1) capable of allowing an intake of air into the container, said ventilation means being positioned on one of said flexible walls (2) or on said at least one member for accessing said internal volume (3); said ventilation means comprising an air-permeable membrane. The present invention also relates to a method for decontaminating or sterilising a volume or a surface using a container filled with a liquid such as a biocide.
摘要:
A continuous process for making a multi-panel sterilization assembly, the process including the steps of: providing a moving, continuous base web; providing a plurality of subassemblies; applying the subassemblies in position on the moving, continuous base web to define repeating portions that incorporate the subassemblies and alternating portions that lack such subassemblies; providing side tabs; applying the side tabs in position on the moving, continuous base web with respect to at least one edge of the portions that incorporate the subassemblies; attaching the subassemblies and the side tabs to the moving, continuous base web to form a continuous work-piece; and separating the continuous work-piece into individual multi-panel sterilization assemblies, each multi-panel sterilization assembly comprising a barrier panel, a fold protection panel and at least one side tab.
摘要:
A multi-panel sterilization assembly that includes a barrier panel formed of a permeable material, barrier panel bolsters at or adjacent at least a portion of two edges of the barrier panel, a fold protection panel, and at least one panel attachment means. The barrier panel has a first end and a second end opposite the first end such that the barrier panel has a length that is the distance from the first end to the second end and a midpoint along the length generally delineating the barrier panel into a content receiving region and a content covering region. The barrier panel bolsters prevent the edges of the barrier panel from folding back onto itself, i.e. back towards the unfolded position, during unfolding of the barrier panel after sterilization.
