Abstract

A cuff of an artificial urinary sphincter system includes a frame and an inflatable balloon. The frame has a first end spaced away from a second end by a gap, where the gap extends from a top edge to a bottom edge of the frame to provide an opening in the frame. The frame has a frame length measured along an interior surface of the frame from the first end to the send end of the frame to define a first quadrant that extends from the first end for a distance of about 25% of the frame length and a second quadrant that extends from the second end for a distance of about 25% of the frame length. A first inflatable balloon attached to the interior surface of the frame in the first quadrant of the frame.

First claim

What is claimed is:

1. A cuff of an artificial urinary sphincter system, the cuff comprising:
a frame having a first end spaced away from a second end by a gap, where the gap extends from a top edge to a bottom edge of the frame to provide an opening in the frame sized to allow the frame to be placed around a portion of a urethra, where the frame has a frame length measured along an interior surface of the frame from the first end to the second end of the frame to define a first quadrant that extends from the first end for a distance of about 25% of the frame length and a second quadrant that extends from the second end for a distance of about 25% of the frame length;
a first inflatable balloon attached to the interior surface of the frame in the first quadrant of the frame; and
a second inflatable balloon attached to the interior surface of the frame in the second quadrant of the frame;
wherein the first inflatable balloon is separate from and spaced apart from the second inflatable balloon;
wherein an entirety of the first inflatable balloon is located in the first quadrant of the frame.

2. The cuff of claim 1 , wherein the gap provides the frame with a C-shaped conformation in lateral cross-section.

3. The cuff of claim 1 , wherein the gap provides the frame with a C-shaped conformation in lateral cross-section, and the C-shaped conformation in lateral cross-section extends along an arc of more than 270 degrees and less than 360 degrees.

4. The cuff of claim 1 , wherein the interior surface of the frame includes a convex lobe extending from the top edge to the bottom edge of the frame with the convex lobe located opposite of the gap.

5. The cuff of claim 1 , wherein the frame is a rigid frame that is resistant to flexing such that a width of the gap between the first end and the second end of the frame remains substantially unchanged for a pressure applied to the interior surface of the rigid frame of less than 120 cm H2O.

6. The cuff of claim 1 , wherein the top edge and the bottom edge of the frame each extend along an arc of more than 180 degrees and less than 330 degrees.

7. The cuff of claim 1 , wherein the top edge and the bottom edge of the frame each extend along an arc of more than 270 degrees and less than 330 degrees.

8. A cuff of an artificial urinary sphincter system, the cuff comprising:
a C-shaped frame provided with a slot that bisects the frame into a first lateral section and a second lateral section, the slot sized to have a width that allows the slot to pass over an outside diameter of a urethra to allow the frame to be placed around a portion of the urethra; and
an inflatable balloon attached to an interior surface in the first lateral section of the frame between the slot and a midpoint of the frame opposite of the slot;
wherein the inflatable balloon is configured to inflate to occupy substantially all of a volume of the first lateral section of the frame to thus coapt the urethra within the second lateral section of the frame against an interior surface of the second lateral section of the frame.

9. The cuff of claim 1 , wherein an entirety of the second inflatable balloon is located in the second quadrant of the frame.
