Container for the packaging of a hollow endoprosthesis
First Claim
1. A container for packing a prosthesis comprising:
- a sterile inner wrapping surrounding a chamber shaped for receiving the prosthesis, the inner wrapping having a fluid-tight wall with at least one gas-permeable region;
a sterile outer wrapping substantially enclosing the inner wrapping and having at least one gas-permeable region; and
first and second inner ports in the inner wrapping fluidly coupled to first and second outer ports, respectively, in the outer wrapping for providing fluid access to the chamber.

Abstract
The container for packing hollow endoprostheses (8) comprises two germ-proof wrappings (1, 2). In accordance with the invention the inner wrapping (1) consists of a water-tight wall (10, 11) and various connection points (40, 50, 60). At least two of the connection points (40) are provided as access into the cavity of the prosthesis (8) and one is provided as an outlet (50) for liquids for treating the prosthesis. The outer wrapping (2) comprises through-pieces (42, 52, 62), which are associated with the connection points of the inner wrapping. The two wrappings are permeable to gas at least some regions. In accordance with the invention the container has a second application apart from its protective function: for example, in the case of a hybrid prosthesis for vascular replacement, to perform the charging of the prosthesis with the patient'"'"'s own endothelial cells in the container.

11. A storage system comprising:
-
a vascular prosthesis charged with a patient'"'"'s endothelial cells; and a container for housing the prosthesis comprising; a sterile inner wrapping enclosing the prosthesis and having a fluid-tight wall with portions that are gas-permeable and at least one inner opening providing fluid access to the prosthesis; and a sterile outer wrapping enclosing the inner wrapping and having at least one outer opening coupled to the inner opening, the outer wrapping having portions that are gas-permeable.

12. A method for preparing a hybrid prosthesis for implantation into a patient'"'"'s body comprising the steps of:
-
(a) housing the prosthesis in a chamber enclosed by an inner wrapping having a fluid-tight wall with at least one gas-permeable region and having first and second inner ports, the inner wrapping being enclosed by an outer wrapping having at least one gas-permeable region and first and second outer ports fluidly coupled to the inner ports; (b) connecting at least the first outer port to a fluid delivery source; (c) sealing the second inner port; (d) pumping water through the first inner and outer ports to force the water through an outer wall of the prosthesis into a hollow bore within the prosthesis, the water displacing air from the chamber through the gas-permeable regions of the inner and outer wrappings; (e) securing the prosthesis to a fixed position within the inner wrapping so that the prosthesis is enveloped by the water; (f) pumping a suspension of endothelial cells from the patient through the first inner and outer ports to force the endothelial cells into the outer wall of the prosthesis; and (g) opening an overflow port to allow the water to exit the chamber. - View Dependent Claims (13)

14. A container for packing a prosthesis comprising:
-
a sterile inner wrapping surrounding a chamber that is adapted for the prosthesis, the inner wrapping having a water-tight wall with inner and outer surfaces and at least one gas-permeable region; a sterile outer wrapping completely enclosing the inner wrapping so that the outer surface of the inner wrapping remains sterile, the outer wrapping being removable from the inner wrapping and having at least one gas-permeable region; and at least one opening in the inner wrapping fluidly coupled to at least one opening in the outer wrapping for providing fluid access to the chamber.
