Definitions
- the invention relates generally systems and methods to compress or anchor soft tissue. Disclosed herein are systems and methods for tissue anchoring using one or more anchoring assemblies.
- the present disclosure provides anchoring system and methods.
- FIGS. 1-17B illustrate various embodiments of anchoring assemblies.
- T-Anchors generally serve only to anchor to a point inside tissue or adjacent to a tissue surface.
- the suture tails must be tied between two T-Anchors to achieve tissue compression and the anchors are not generally easily removed.
- a T-anchor is a medical device which has been used for moving two body walls into proximity and for maintaining those two walls in proximity for an extended period of time.
- the T-anchor typically includes an anchor bar having a longitudinal configuration and a tether, such as a suture attached to the bar and extending laterally from the bar.
- An introducer can be used to pass the anchor bar through the two walls and to deploy the anchor bar on the far side of the second wall.
- the suture is left to extend through the two walls, and can be provided with a bolster on the near side of the two walls which is slidable along the suture. As the suture is pulled and the bolster is pushed, the anchor bar seats against the second wall which is drawn into proximity with the first wall. A knot tied in the suture on the proximal side of the bolster maintains the anchor in this operative position with the two walls in close proximity.
- disclosed herein are improved systems and methods that allow for removal of a placed T-Anchor.

- the embodiments incorporate two individual anchor elements connected by a flexible member thus allowing for significant relative movement/rotation between them.
- the specific path the flexible element takes through the individual elements can enhance rotational movement of the anchoring elements when tension is applied to the flexible element. This effect can enhance the initial anchoring of the elements into soft tissue by increasing the distance between the tips of the anchoring elements and more aggressively engaging the soft tissue.
- the systems and methods use elements attached together with a flexible element to enhance expansion and engagement with tissue while maintaining a low delivery profile compared with typical barbs. In some embodiments, there can be greater expanded size to delivery size ratio. In some embodiments, the systems and methods use tension in the suture to actively expand elements. In some embodiments, the systems and methods maintain removability of the anchors by having a suture attached to the distal end of the distal anchor. When the distal suture is pulled proximally, the anchor repositions itself into an orientation that facilitates removal from the soft tissue. In some embodiments, as opposed to the typical T-Anchors which do not reliably anchor within tissue at the delivered site, the systems and methods described herein can actively engage tissue for secure and precise anchoring. T-Anchors are better suited to anchor to the edge of a tissue interface and not within tissue.

Abstract
Description
- The present application claims priority benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application No. 63/113373 filed on Nov. 13, 2020, the disclosures of which is incorporated by reference herein in its entirety.
- In some aspects, the invention relates generally systems and methods to compress or anchor soft tissue. Disclosed herein are systems and methods for tissue anchoring using one or more anchoring assemblies.
- In many surgical procedures, there is a need to compress or anchor tissue.
- The present disclosure provides anchoring system and methods.
-
FIGS. 1-17B illustrate various embodiments of anchoring assemblies. - In some embodiment, disclosed herein are improved systems and methods to compress or anchor to soft tissue in a permanent or temporary way. Conventionally, T-Anchors generally serve only to anchor to a point inside tissue or adjacent to a tissue surface. The suture tails must be tied between two T-Anchors to achieve tissue compression and the anchors are not generally easily removed. A T-anchor is a medical device which has been used for moving two body walls into proximity and for maintaining those two walls in proximity for an extended period of time. The T-anchor typically includes an anchor bar having a longitudinal configuration and a tether, such as a suture attached to the bar and extending laterally from the bar. An introducer can be used to pass the anchor bar through the two walls and to deploy the anchor bar on the far side of the second wall. The suture is left to extend through the two walls, and can be provided with a bolster on the near side of the two walls which is slidable along the suture. As the suture is pulled and the bolster is pushed, the anchor bar seats against the second wall which is drawn into proximity with the first wall. A knot tied in the suture on the proximal side of the bolster maintains the anchor in this operative position with the two walls in close proximity. In some embodiments, disclosed herein are improved systems and methods that allow for removal of a placed T-Anchor. In some embodiment, when combined with a T-anchor in an assembly, the improved systems and methods allow for permanent tissue compression/apposition without the need to tie knots. Disclosed herein are figures and descriptions of some advantageous effects. In some embodiments, the systems and methods include removable T-Anchors. In some embodiments, the systems and methods include ratcheting T-Anchors. In some embodiments, the systems and methods include multi-element anchors. In some embodiments, the systems and methods include multi-element anchors that facilitate anchoring in soft tissue with barbs. In some embodiments, the systems and methods include two individual anchor elements connected by a flexible member thus allowing for significant relative movement/rotation between them. In some embodiments, the systems and methods include a variety of anchoring assemblies, wherein an anchor or anchoring assembly can include any feature of an anchor or anchoring assembly described herein.

The following embodiments and those described herein illustrate multi-element anchors that facilitate anchoring in soft tissue. The embodiments incorporate two individual anchor elements connected by a flexible member thus allowing for significant relative movement/rotation between them. The specific path the flexible element takes through the individual elements can enhance rotational movement of the anchoring elements when tension is applied to the flexible element. This effect can enhance the initial anchoring of the elements into soft tissue by increasing the distance between the tips of the anchoring elements and more aggressively engaging the soft tissue.
- In some embodiments, the systems and methods use elements attached together with a flexible element to enhance expansion and engagement with tissue while maintaining a low delivery profile compared with typical barbs. In some embodiments, there can be greater expanded size to delivery size ratio. In some embodiments, the systems and methods use tension in the suture to actively expand elements. In some embodiments, the systems and methods maintain removability of the anchors by having a suture attached to the distal end of the distal anchor. When the distal suture is pulled proximally, the anchor repositions itself into an orientation that facilitates removal from the soft tissue. In some embodiments, as opposed to the typical T-Anchors which do not reliably anchor within tissue at the delivered site, the systems and methods described herein can actively engage tissue for secure and precise anchoring. T-Anchors are better suited to anchor to the edge of a tissue interface and not within tissue.
