Balloon loaded dissection devices and methods for using such devices are disclosed. The devices include an elongate balloon and may be provided with a central lumen. The device may have a guide tube to provide columnar support. In a further aspect, the guide tube may have a spoon-shaped shroud attached to a distal end. The guide tube receives the guide rod, scope or other surgical instrument and may have a stop member. By using the guide rod or scope as a pushing member, the device may be advanced alongside the vessel it is desired to dissect free from attached tissue. A balloon cover may be provided to surround the balloon and facilitate compression of the balloon after it is deflated. In an additional feature, the guide rod and/or tubular member are plastically bendable into a curved shape such that the balloon dissector may be adjusted.
