FENESTRATED DECOUPLING SYSTEM FOR INTERNAL SELECTIVE ATTACHMENT TO SOFT TISSUE ORGANS

摘要

An attachment system for selectively attaching to an interior surface of a hollow member, which includes an expanding device selectively enlargeable from a first size position to an enlarged second size position, a friction enhancement disposed about the expanding device that is engageable with the interior surface of the hollow member when the expanding device is in the enlarged position, and a fenestrated decoupling system extending between at least a portion of the friction enhancement of the expanding device and the interior surface of the hollow member. The fenestrated decoupling system generally prevents contact of the friction enhancement with the interior surface of the hollow member when the expanding device is in the first size position and permits contact of the friction enhancement with the interior surface of the hollow member when the expanding device is in the enlarged position.
