Disposable tray for contrast media medical procedures
First Claim
1. A tray assembly for holding a set of medical products for use in a selected procedure, the assembly comprising:
- a one-piece tray base, the tray base defining a sterile region, a non-sterile region, and a demarcation zone between the regions, the tray base defining a sealing surface with a sealing surface portion peripherally around each of the sterile and non-sterile regions, each sealing surface portion including part of the demarcation zone;
the tray base sterile region defining a plurality of medical product-receiving pockets, each pocket having an internal bottom, within which the set of medical products for use in the selected procedure are contained;
the tray base non-sterile region defining a pocket having an integral bottom in which a vial of contrast agent which is unsuited to sterilization is contained;
a first lid portion sealed to the sealing surface portion around the tray base sterile region, the first lid portion being impermeable to pathogenic microorganisms, whereby pathogenic microorganisms are blocked from contaminating the sterile region, the medical products, and an interior of the first lid portion, the first lid portion including at least a portion which is permeable to gaseous sterilants, whereby the medical products, the sterile region, and the interior of the first lid portion are sterilizable after the first lid portion is sealed to the tray;
a second lid portion sealed to the sealing surface portion around the non-sterile tray base region;
wherein either one of the sealed sterile region and sealed non-sterile region can be separately opened without affecting the seal integrity of the other sealed region.

Abstract
A unitary tray base (10) includes a first region (20) and a second region (22) which are separated by a demarcation zone (16). Medical products (30) are received in pockets (32) of the first tray region. An ethylene oxide permeable lid portion (40) seals the first tray portion from the second tray portion and the ambient atmosphere. The tray and received medical products are sterilized with ethylene oxide or other sterilizing procedures. After the sterilization, a vial (50) of contrast agent, which cannot be present during the sterilizing, is placed in a pocket (50a) of the second tray portion. A second lid portion (52) seals the vial in the second tray portion. The lid portions are marked (60-68) to indicate that the contents of the first region are sterile and the contents of the second region are not.

9. A tray assembly comprising:
-
a tray base which defines a first region and a second region, the first and second regions each defining at least one product-receiving pocket therein, each pocket having an integral bottom; a first set of products contained in the pockets of the first tray region; a first lid portion sealed to the tray base and covering the first tray region only such the first lid portion seals the first tray region from the second tray region and the ambient atmosphere, the products of the first tray region being sterilized after attachment of the first lid portion; a product which is degraded by the sterilization process contained in one pocket of the second tray region; a second lid portion sealed to the tray base and covering the second tray region only sealing the second tray region from the first tray region and the ambient atmosphere; wherein either one of the first and second lid portions is removable without affecting the seal integrity of the other lid portion. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of packaging a set of medical products for a selected medical procedure, the method comprising:
-
forming a one-piece tray base having a first region including a plurality of medical product receiving pockets with integral bottoms, a second region defining a contrast agent vial-receiving pocket with an integral bottom, and a demarcation zone between the regions, the tray base defining a sealing surface portion peripherally around each of the first and second regions, each sealing surface portion including part of the demarcation zone; placing the set of medical products in the pockets of the first tray region; sealing a first lid portion to the sealing surface portion around the first tray region such that the first tray region is sealed from the second tray region and the ambient atmosphere, the first lid portion blocking microorganisms from passing therethrough and being permeable to sterilant gases; sterilizing the tray base, the first lid portion, and the medical products sealed in the first tray region with a sterilant gas; placing a vial of contrast agent in the contrast agent vial-receiving pocket of the second tray region; sealing a second lid portion to the sealing surface portion around the second tray region; wherein either one of the first and second lid portions is removable without affecting the seal integrity of the other lid portion.
