## Abstract

Disclosed is an inventive method for an aseptic assembly of a multi-component medical device. In this method a first component of the medical device is provided in a first container and a second component of the medical device is provided in a second container. Each of the first and second separated containers have a rupturable portion. The first component in the first container is sterilized using a first sterilization technique and the second component in the second container is sterilized using a second sterilization technique. The first and second containers are joined while arranging the rupturable portions in an overlapping configuration which is aseptically sealed against the surroundings. Finally, one of the components is transferred through the rupturable portions and the components are aseptically assembled to form the medical device as a sterile package.

## Claims

### Claim 1

A method for an aseptic assembly of a multi-component medical device, comprising:
a) providing a first component of the medical device in a first container having a first rupturable portion;
b) providing a second component of the medical device in a second container having a second rupturable portion;
c) sterilizing the first component in the first container using a first sterilization technique and sterilizing the second component in the second container using a second sterilization technique, wherein the first and second sterilization techniques are different and are selected from the group consisting of gas sterilization, irradiation sterilization, and thermal sterilization;
d) joining the first and second containers to form a sterile kit wherein the first and second rupturable portions are arranged in an overlapping configuration which is aseptically sealed against the surroundings;
e) transferring one of the components through the first and second rupturable portions and aseptically assembling the components to form the medical device as a sterile package; and wherein step e is performed within an interior space enclosed by the first and second containers and wherein the method further comprises removing the medical device assembled during step e from the first and second containers before using the medical device.

### Claim 2 (depends on 1)

The method according to claim 1, wherein one of the containers has a gas-permeable and aseptically sealed membrane, and wherein a sterilization gas is introduced and released through the membrane.

### Claim 3 (depends on 2)

The method according to claim 2, wherein the sterilization gas is introduced and released through the membrane by a pressure alternating procedure.

### Claim 4 (depends on 1)

The method according to claim 1, wherein one of the first and second sterilization techniques is gas sterilization with ethylene oxide gas.

### Claim 5 (depends on 4)

The method of claim 4, wherein one of the containers has a gas-permeable and aseptically sealing membrane, and wherein the ethylene oxide gas is introduced and released through the membrane.

### Claim 6 (depends on 1)

The method according to claim 1, wherein one of the first and second sterilization techniques uses an electron beam.

### Claim 7 (depends on 1)

The method according to claim 1, further comprising arranging a plurality of first or second containers including respective components in a sterile-tight outer covering before the sterilizing step.

### Claim 8 (depends on 1)

### Claim 9 (depends on 1)

The method according to claim 1, wherein at least one of the first and second containers has an adhesive portion, and wherein the containers are adhered to each other using the adhesive portion.

### Claim 10 (depends on 1)

The method according to claim 1, further comprising forming an aseptic seal around the rupturable portions by bonding together sealing portions of the first and second containers.

### Claim 11 (depends on 1)

The method according to claim 1, wherein the step of transferring one of the components includes rupturing both the first and second rupturable portions.

### Claim 12 (depends on 1)

The method according to claim 1, wherein the component to be transferred is used to rupture the first and second rupturable portions.

### Claim 13 (depends on 1)

The method according to claim 1, further comprising manipulating at least one of the first and second components by using a handling aid provided within the containers.

### Claim 19 (depends on 18)

The method according to claim 18, wherein the thin flexible sheet of material is a metal foil.

### Claim 20 (depends on 1)

The method according to claim 1, wherein the multi-component medical device is a skin mountable sensor device.

### Claim 21

An aseptic kit for a multi-component medical device, comprising: a first component of the medical device in a first container having a first rupturable portion and a second component of the medical device in a second container having a second rupturable portion, wherein the first component is maintained sterile by a first sterilization technique and the second component is maintained sterile by a second sterilization technique different than the first sterilization technique, the first and second sterilization techniques being selected from the group consisting of gas sterilization, irradiation sterilization and thermal sterilization;
wherein the first and second containers are connected to each other such that the first and second rupturable portions are arranged in an overlapping configuration and wherein the first and second containers are bonded to each other to form an aseptic seal around the first and second rupturable portions; and wherein one of the first and second components is configured to be transferred through the first and second rupturable portions to assemble the medical device; and wherein the first rupturable portion is disposed on a lid attached to the first container, the lid being configured such that detachment of the lid from the first container allows removal of the medical device from the first and second containers before use of the medical device.

### Claim 22 (depends on 21)

The aseptic kit of claim 21, wherein the multi-component medical device is a skin mountable sensor device.
