Devices and related methods for treating incontinence
A device completely disposable within a bodily lumen of a patient and for controlling flow through the bodily lumen having a device body having a proximal end, a distal end and a device lumen within the device body extending from the proximal end to the distal end and a fixation element extending from the outer wall of device body adapted and configured to engage with the wall of the bodily lumen. The device body is adapted and configured to move from a position where the device lumen blocks flow through the bodily lumen to a position where the device lumen allows flow through the bodily lumen. In other configurations, there are one or more valves within the device lumen adapted and configured to move between a position to block flow through the bodily lumen and a position to allow flow through the bodily lumen. There is also a method for implanting a device within a body lumen by placing a device having a device body and fixation elements extending from the device body on a catheter and then dilating the body lumen such that the device body and the fixation elements may advance through the dilated body lumen without the fixation elements engaging the wall of the body lumen. Next, advancing the device to an implant site within the body lumen and then engaging the walls of the body lumen with the fixation elements.
1 . A device completely disposable within a bodily lumen of a patient and for controlling flow through the bodily lumen, comprising:
a device body having a proximal end, a distal end and a device lumen within the device body extending from the proximal end to the distal end, the device body completely disposed within the bodily lumen so that all flow through the bodily lumen flows through the device lumen; and
a fixation element extending from the outer wall of device body adapted and configured to engage with the wall of the bodily lumen; wherein,
the device body is adapted and configured to move from a position where the device lumen blocks flow through the bodily lumen to a position where the device lumen allows flow through the bodily lumen.
2 . The device of claim 1 wherein the device body moves in response to increased intraluminal pressure applied anatomically proximal to the device.
3 . The device of claim 2 wherein the increased pressure is applied for longer than three seconds.
4 . The device of claim 1 wherein at least one of the proximal device end or the distal device end is angled to facilitate movement of the device between positions.
5 . The device of claim 1 wherein the fixation element withdraws into the sidewall of the device body or the device lumen.
6 . The device of claim 1 wherein the fixation element is a balloon.
7 . The device of claim 1 wherein the fixation element has a stowed condition where the fixation element is engaged with the bodily lumen wall and a deployed condition where the fixation element engages with the bodily lumen wall.
8 . The device of claim 1 wherein the bodily lumen is the urethra.
9 . The device of claim 1 wherein the device lumen is non-linear.
10 . A device completely disposable within a bodily lumen of a patient and for controlling flow through the bodily lumen, comprising:
a device body having a proximal end, a distal end and a device lumen within the device body extending from the proximal end to the distal end, the device body completely disposed within the bodily lumen so that all flow through the bodily lumen flows through the device lumen; and
one or more valves within the device lumen adapted and configured to move between a position to block flow through the bodily lumen and a position to allow flow through the bodily lumen.
11 . The device of claim 10 further comprising a fixation element extending from the outer wall of device body adapted and configured to engage with the wall of the bodily lumen.
12 . The device of claim 10 wherein the one or more valves within the device lumen includes a magnetically activated rotary valve.
13 . The device of claim 10 wherein the one or more valves within the device lumen includes a flap valve.
14 . The device of claim 10 wherein the one or more valves within the device lumen are angled relative to the device lumen.
15 . The device of claim 10 wherein the one or more valves within the device lumen move between a position to block flow through the bodily lumen and a position to allow flow through the bodily lumen by moving a fluid from the interior of a valve to a cavity in the sidewall of the device body.
16 . The device of claim 10 wherein the one or more valves within the device lumen is a valve have a pair of disks mounted on, in or within the sidewall of the bodily lumen, the pair of disks rotatable relative to one another to move between positions.
17 . A method for implanting a device within a body lumen, comprising: placing a device having a device body and fixation elements extending from the device body on a catheter;
dilating the body lumen such that the device body and the fixation elements may advance through the dilated body lumen without the fixation elements engaging the wall of the body lumen;
advancing the device to an implant site within the body lumen; and engaging the walls of the body lumen with the fixation elements.
18 . The method of claim 17 wherein the dilating step is performed by inflating a balloon or expanding a structure on the catheter.
19 . The method of claim 18 wherein the balloon is distal to the distal end of the device.
20 . The method of claim 17 wherein the dilating step is performed by inflating a balloon or expanding a structure on the device.
21 . The method of claim 17 wherein the engaging step is performed by rotating the device relative to the bodily lumen.
