Abstract
A body structure is manipulated by first introducing a bulking material, such as a length of material, into an interior of the body structure in either open or laparoscopic surgical procedures. After the bulking material is introduced, an exterior region of the body structure may be manipulated while the material remains within the interior of the body structure. Typically, manipulation comprises resection of the body structure from surrounding tissue. The resected body structure may then be removed.
Claims60
A method for manipulating a cyst body structure, said method comprising:
- penetrating an access tube through an exterior wall of the cyst body structure, wherein said access tube seals to the cyst body structure to produce a passage into an interior of the cyst body structure while preventing leakage therefrom;
- introducing at least one length of material through the passage of said access tube into the interior of the cyst body structure to substantially fill the entire interior of the cyst body structure;
- and
- manipulating an exterior region of the cyst body structure while said length of material remains within the interior of the cyst body structure;
- wherein manipulating comprises separating at least a portion of the exterior of the cyst body structure from surrounding tissue while said length of material remains within the interior of the cyst body structure.
