Abstract
The invention provides systems and methods for interfering with the adhesion formation process. In some embodiments, the present invention makes use of intermittent blunt dissection of fibrin bridging adjacent tissues prior to the formation of adhesions. Dissection is generally provided by pulsing a balloon implanted between the tissues. Optionally, the balloon will comprise an elastic structure to disrupt the formation of fibrin between the balloon and the surrounding tissues. Alternatively, the balloon may be at least partially covered by a bio-active anti-adhesion material. In some embodiments, the anti-adhesion material forms an envelope which is left between the tissues when the balloon is removed.
