External retention mechanism for suture anchor

Among other things, embodiments of a retaining mechanism for holding a portion of the suture of a suture anchor are disclosed. When a suture anchor is inserted into a patient, the portion of the suture extending from the body is held in tension by a two-piece snap-fit mechanism. One piece has a base with an extending shaft portion and a bulbous head, and a lumen runs through the shaft. The second piece has a hole or space for snapping the second piece onto the first piece. The extending portion of the suture runs through the lumen in the first piece and can be wrapped around the shaft. Snapping the second piece onto the first contains the suture and prevents loss of tension in it.

The suture thread is connected to the second anchor via clipping.

Systems, methods and devices for embolic protection
11207170 · 2021-12-28 · ·

Embodiments of the present disclosure are directed to systems, methods and devices for providing embolic protection in a patient. In some embodiments, the device is configured for implantation in a body vessel including fluid flow. The device may assume, or be constrained to assume, an undeployed state and a deployed state. In the undeployed state, the device or a portion thereof has a substantially linear shape configured to reside in the lumen of a thin needle having a diameter of less than about 0.5 mm (for example), in the deployed state, the device has a primary axis. When the device is implanted the primary axis is approximately perpendicular to the fluid flow. In some embodiments, the device comprises a thin filament body. In the deployed state the filament takes a helical shape. Emboli that are larger than the distance between consecutive turns or windings of the helix are thus filtered by the device and are prevented from causing deleterious conditions such as stroke or pulmonary embolism. The device may be made of a super-elastic alloy. Thus, the device may transition between the undeployed and the deployed states without plastic deformation. Delivery systems and method for implanting such devices are also disclosed.

Re-Tensionable Suture Anchor System and Related Methods

A system and method comprising an anchor assembly including an anchor and a locking element, a tensionable fixation member (e.g., surgical suture, tape, etc.), and a release member, wherein the anchor further comprises a first end, second end and anchor body. This re-tensionable anchor is designed to be implanted into bone. One end of a suture or other tensionable fixation member is attached to the tissue on one end to assist with fixation of soft tissue. Once the anchor has been seated in the bone, the second end of the suture or tensionable fixation member is pulled through a “one-way only” passage in body of the anchor. When the tensionable fixation member enters the body of the anchor, it traverses past by bending or deflecting out of the way a locking element within the anchor that will permit passage of the suture and will stay in contact with the fixation member via elastic compression that results from the elastic bending or deflection but prevent it from passing back. This continuous locking on the suture creates fixation security, allows for optimal tensioning, and prevents loosening in the opposite direction. An instrument designed to reach the locking element and deliberately bend or deflect it will allow for loosening the suture to provide for the ability to readjust the tension to the operator's liking.
