Tissue anchors such as those described in U.S. Pat. No. 8,070,743, and U.S. patent application Ser. Nos. 12/137,473, 13/485,887, and 13/896,838 may be used to anchor devices within a bodily space. For example, tissue anchors may be used to anchor a gastrointestinal bypass device within an esophageal lumen.
The function and longevity of an anchored device may be affected by the placement of the tissue anchors. For example, tissue anchors that are uniformly spaced or substantially coplanar may improve the performance and increase the useful life of an anchored device.
An anchored device may need to be coupled to the tissue anchors before the tissue anchors are delivered through the tissue wall. However, an anchored device coupled to the tissue anchors may interfere with and complicate placement and delivery of the tissue anchors.
What is needed are devices and methods to enhance placement accuracy of tissue anchors for anchoring of an anchored device. What is also needed are devices and methods to facilitate delivery of tissue anchors for anchoring of an anchored device.
A method of treating a patient for a condition is described. The condition may include diabetes, heart disease, obesity, obesity-related conditions, and/or other chronic conditions. The method comprises providing a tissue anchor including a tension element, an anchor coupling coupled to a proximal portion of the tension element, and a distal retention element coupled to a distal portion of the tension element. The anchor coupling may be configured to be positioned within a bodily space. The distal retention element may be configured to be deployed on a distal side of a tissue wall defining the bodily space. The method also comprises selecting a placement in the tissue wall for the tissue anchor, delivering the distal retention element through the placement in the tissue wall, deploying the distal retention element on the distal side of the tissue wall, and positioning the anchor coupling within the bodily space. The method also comprises providing an anchored device configured to be positioned within the bodily space. The anchored device includes a device coupling configured to be coupled to the anchor coupling. The method also comprises delivering the anchored device into the bodily space, and coupling the device coupling to the anchor coupling to anchor the anchored device in the bodily space.

Anchored device 5100 may be generally cylindrical, conical, or any other suitable configuration or shape.

Alternatively, device coupling 5130 may be configured to be irremovably coupled to anchor coupling 5310 and/or tension element 5350. Device coupling 5130 may be coupled to anchored device 5100 as a separate element glued, stitched, welded, or otherwise attached to anchored device 5100. Alternatively, device coupling 5130 may be coupled to anchored device 5100 by being formed integrally with one or more elements of anchored device 5100. Device coupling 5130 may include a clip 6310, barb 6320, loop 6330, hitch 6340, strut 6350, fin 6370, strut 6380, loop coupling 6400, halo 6410, halo 6420, knob 6430, cinching loop 6440, cinching loop 6450, cinching loop 6470, strut 6500, strut 6520, strut 6540, strut 6560, ring 6580, strut 6590, block 6610, strut 6630, strut 6650, strut 6670, strut 6690, strut 6710, strut 6730, cleats 6750, strut 6760, hole 6780, magnet 6790, strut 6800, socket 6820, clip 6830, pin 6840, pin 6850, pin 6860, clip 6870, hole 6880, socket 6890, and/or any other suitable coupling or attachment device.
Anchored device 5100 may be delivered using endoscopic tools or any other suitable devices and/or methods. Anchored device 5100 may be delivered after tissue anchor 5300 is delivered. Alternatively, anchored device 5100 may be delivered before tissue anchor 5300, or coupled to tissue anchor 5300 and delivered at the same time as tissue anchor 5300.
Thus, in one embodiment, one or more tissue anchors 5300 may be delivered first, and then anchored device 5100 may be delivered second. Device coupling 5130 of anchored device 5100 may then be coupled to anchor coupling 5310 of tissue anchor 5300. This may ease delivery of tissue anchors 5300 and anchored device 5100 by dividing the procedure into two steps. Also, because anchored device 5100 does not encumber or otherwise interfere with tissue anchors 5300 during delivery of tissue anchors 5300, this may enhance placement accuracy of tissue anchors 5300. The use of device coupling 5130 and anchor coupling 5310 may allow anchored device 5100 to be removably coupled to tissue anchor 5300, which allows for anchored device 5100 to be replaced with a similar or different device. The option to place tissue anchors 5300 first may also allow at least a portion of any slack in tension element 5350 to be removed or taken up before anchored device 5100 is coupled to tissue anchors 5300.
