Abstract: A medical device sterile barrier system that is easier for surgical personnel to use by allowing easier opening and removal of the medical device from the sterile packaging, includes a sterile bag within which a medical device is held secure via a removable holster, the holster being fashioned with a hinge feature such that the holster has a clamshell arrangement and folds in half along the hinge feature to clamp the medical device parts in place between the two halves of the clamshell. To remove the medical device the holster is simply unfolded about the hinge feature to reveal the parts of the device, which can then be lifted out of the holster and assembled in the usual way. There are thus no polymer tab features forming part of the holster and interacting with the device to secure it in place that need removal before the device can be used.
