Abstract

A method for assembling a package for an active medical device which comprises making an opening in a wall of a recess shaped to receive the device, placing a gasket against the wall and about a band mounted through a flat portion of the wall, inserting the band through the opening so the gasket is flush against the wall, installing an outer part about the band to hold the gasket against the wall to form a sterile barrier, and placing a lid over the recess to contain the device within a sterile field.

Claims

1. A method for assembling a package containing an active medical device having sensors comprising the following steps:

making an opening in a wall of a recess defined by a film member, which recess is shaped to receive the active medical device;

inserting the active medical device in the recess;

inserting through the opening in the wall a band of an inner part of a junction mounted through a flat portion of the wall;

placing a gasket against the wall and about the band so the gasket is flush against the wall;

installing an outer part coaxially about the band whereat it extends beyond the opening to hold the gasket tightly against the wall to form a sterile barrier; and

placing a lid against a flange of the film member to cover the recess and thereby contain the active medical device within a sterile field in the recess.

2. A method according to claim 1 in which the outer part includes a threaded collar which is threaded onto the extended band to secure outer and inner junction parts.

3. A method according to claim 1, in which test means adapted to allow the passage of electrical and optical signals is included in the junction so that the sensors of the medical device may be tested without breach of the sterile field.
