Abstract

Surgical devices and methods achieve a desired configuration of one or more anatomical structures, e.g. by suction or inflation, and then optionally deploy a stabilizing or fastening agent or holding device, for example a helical staple, to stabilize the anatomical structure in the desired configuration. Aspects of the invention can be used in the treatment of incontinence, coronary artery blockage, and blockages or strictures in other anatomical structures. Additionally, embodiments of the invention also can be used to create anastomoses between anatomical structures, and/or to create or reverse functional vasectomies, tubal ligations and the like. Aspects of the invention are particularly (though not exclusively) applicable in minimally invasive surgical settings.
