Abstract
Balloon loaded dissection devices with elongate balloons and a pushing member are disclosed for creating a tunnel alongside an elongate vessel in the body. The devices may utilize an elongate balloon of any suitable length which may be formed of an elastic or non-elastic material. The balloon may be of double walled construction and may be provided with a central lumen which may receive a guide rod, scope or other surgical instrument. The device may have a support tube secured to the inner wall of the balloon to provide columnar support for the apparatus. In a further aspect, the support tube may have a spoon-shaped shroud attached to a distal end of the support tube. The support tube receives the guide rod, scope or other surgical instrument and may have a stop member to translate pushing force applied to the guide rod or scope to pushing force on the apparatus. By using the guide rod or scope as a pushing member the apparatus may be advanced alongside the vessel it is desired to dissect free from attached tissue. A balloon cover which may be elastic or resilient is 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 into a curved shape. The devices may also have an ergonomic handle which provides the surgeon greater control of the dissector and is also adapted to receive and support a scope instrument and light.
