Abstract
A dysfunctional sphincter muscle may be treated by shortening the muscle to plicate it and restore its functionality. Plicating the sphincter muscle as described effectively shortens the muscle and permits the muscle to perform its function of closing off the body passage or opening with which it is associated without conventional surgery to expose the sphincter muscle and shorten it. Thus, treatment for incontinence can be achieved by shortening the associated sphincter muscle without surgery that exposes the muscle itself and requires the surgeon to manually grab hold of the muscle and shorten it.
Claims3
A tool for use with a sphincter muscle associated with a bodily passage or opening, the tool comprising:
- a first portion through which at least one first pin is configured to be extended and retracted;
- a second portion through which at least one second pin is configured to be extended and retracted;
- a joining portion that guides movement of the first portion and the second portion such that in an insertion position the first portion and second portion are configured to be inserted into the bodily passage or opening and then in a plication position the first portion and second portion are configured to be moved in place relative to each other such that the first pin and the second pin can be moved closer together while providing a hollow space within the tool in the bodily passage or opening, and wherein in the insertion position, the first pin and the second pin are configured to be extended outwardly from the tool so as to engage the sphincter muscle, such that the first pin and second pin do not move relative to the sphincter muscle, and in the plication position, the first portion and second portion are configured to be moved relative to each other with the first and second pins extended, and thereafter, the first and second pins are configured to be retracted and the first and second portions can be moved relative to the sphincter muscle to permit removal of the tool from the bodily passage or opening.
