Packaging units for use with elongate medical devices such as catheters. An example packaging unit includes a mounting card into which a number of tabs are cut at predetermined angles and shapes. At least some of the tabs are provided in large tab/small tab pairs. The angle and size combination provides for securing the elongate medical device to the card, while reducing trauma experienced by the device during removal from the card. Also, a double tab system is provided in the packaging unit for receiving a hub and strain relief to hold those parts securely. The card may be scored along at least a first side such that, prior to placing a sterile barrier, such as a plastic wrapping or envelope, around the mounting card to sterilely seal a device therein, the card may be bent along the scoring line to lift the sterile barrier off of a surface of the mounting card. The step of bending a portion of the card along the storing line make removal of a device from the mounting card easier and renders the mounting card more rigid and less likely to bend and cause damage to an elongate medical device stored thereon.
