Overdrive Prevention for Expandable Anchor
20170340435 · 2017-11-30 ·

Surgical devices and methods are provided for anchoring tissue to bone, and more particularly methods and devices are provided for preventing over-insertion of an expander into a sheath of a two-piece anchor. For example, a tendon anchoring system is provided with an anchor assembly and an inserter tool. The anchor assembly includes a sheath with a threaded lumen and a threaded expander screw configured to be threadably disposed within the sheath to cause the sheath to expand outward. The inserter tool includes an elongate outer shaft with a distal end configured to couple to a proximal end of the sheath, and an elongate inner shaft with a distal drive tip configured to engage a proximal end of the expander screw. In one embodiment, the inner shaft can be rotatable relative to the outer shaft to thread the expander screw into the sheath, and the inner shaft can be prevented from rotating relative to the outer shaft when the expander screw is fully threaded into the sheath to prevent over-insertion of the expander screw into the sheath.

Tethers for prosthetic mitral valve

This invention relates to the design and function of a single-tether compressible valve replacement prosthesis which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed combats the process of wear on anchoring tethers over time by using a plurality of stent-attached, centering tethers, which are themselves attached to a single anchoring tether, which extends through the ventricle and is anchored to a securing device located on the epicardium.

A delivery device for tissue anchor delivery is provided. The delivery device includes a first flexible tube having a rigid distal portion attachable to a tissue anchor, a second flexible tube coaxially disposed around the first tube and a tubular sheath covering the second flexible tube. Also provided is a system which includes an imaging device coupler reversibly attached to the delivery device through guides.

Fixation members, assemblies, and related systems and methods

A suture anchor for fixation within an anatomical structure includes an actuation member in contact with an anchor body at a first location thereof. The anchor body is elongate along a direction of elongation and defines a central axis. In a neutral configuration, the anchor body is flat and defines a thickness along a transverse direction and a width along a lateral direction, the width being greater than the thickness. The anchor body has first and second tails that are braided together along a portion of the actuation member from the first location to a second location of the anchor body. The actuation member is configured to apply a force to the braided anchor body so as to actuate the anchor body in a manner increasing its maximum thickness along a second direction that is angularly offset from the direction of elongation.

Adjustable suture button construct

An adjustable construct for fixation of a tendon or ligament graft in a tunnel. The construct comprises a flexible, adjustable loop connected to tissue (for example, graft, ligament or tendon). The adjustable loop may be integrated with an additional tissue supporting device (for example, a wedge or a plug). The tissue is secured within a bone socket/tunnel by adjusting the length of the flexible adjustable loop.

Transcatheter atrio-ventricular valve prosthesis

A transcatheter atrio-ventricular valve prosthesis for functional replacement of an atrio-ventricular valve in a connection channel, having a circumferential connection channel wall structure, between atrial and ventricular chambers of a heart, including an inner device to be disposed in the interior of the connection channel, the inner device having a circumferential support structure which is radially expandable and having a valve attached to the circumferential support structure, and an outer device to be disposed on the exterior of the connection channel, wherein the outer device at least partly extends around the inner device at a radial distance to the inner device, wherein the inner and outer devices form a securing mechanism for securing the circumferential connection channel wall structure therebetween.

TWO-PART ANCHOR WITH ANCHOR INSERTER

Disclosed herein are embodiments of a no-hole-preparation suture anchor including a tubular anchor body, a tapered tip coupled to the anchor body, an eyelet extending transversely through the anchor, and a plurality of longitudinal ribs extending along at least a portion of the anchor length. The material of the tapered tip is harder than that of the anchor body to facilitate insertion. An anchor inserter for use in combination with the suture anchor includes an elongated, tubular shaft defining a cannulation extending between a proximal end and a distal end. A plurality of tines extends distally from the distal end of the shaft. The anchor includes a plurality of longitudinally extending slots, dimensioned to receive respective ones of the inserter tines. The slots extend along the length of the anchor body and continue into the proximal end of the tubular shaft of the distal tip. The circumferential position of each of the slots is further selected such that the slots are circumferentially adjacent to, but do not intersect, the eyelet.

Implant, implantation device, implantation method

An implant suitable for being anchored with the aid of mechanical vibration in an opening provided in bone tissue. The implant is compressible in the direction of a compression axis under local enlargement of a distance between a peripheral implant surface and the compression axis. The implant includes a coupling-in face which serves for coupling a compressing force and the mechanical vibrations into the implant, which coupling-in face is not parallel to the compression axis. The implant also includes a thermoplastic material which, in areas of the local distance enlargement, forms at least a part of the peripheral surface of the implant.

Systems, devices, and methods for securing tissue using a suture having one or more protrusions

Systems, devices, and methods are provided for securing soft tissue to bone. One exemplary embodiment of a surgical repair construct includes an anchor, a filament having a snare formed on one end and a collapsible loop on another end, and a suture having a plurality of stationary protrusions formed therein. The suture is configured to be coupled to detached tissue and have its ends passed through an opening in the snare. The snare can be collapsed around the suture such that at least one of the suture protrusions is proximal of the collapsed snare. The anchor can be disposed in bone and the filament coupled thereto. Accordingly, collapsing the snare around the suture couples the tissue to bone, and applying tension to a tensioning limb of the filament can collapse the collapsible loop to incrementally tighten and secure the tissue to bone. Other exemplary systems, devices, and methods for use with soft tissue repair are also provided.

LARGE PUSH-IN SUTURE ANCHOR

A suture anchor system comprising an anchor and an insert, and methods of use are provided. The anchor body has proximal and distal ends, and opposite first and second lateral sides extending between the proximal end and the distal end. A suture passage comprising a proximal surface and a distal surface extends through the anchor body from a first opening in the first lateral side to a second opening in the second lateral side. A channel extends along a longitudinal axis of the anchor body from a proximal opening in the proximal end of the anchor body to a distal opening in the proximal surface of the suture passage. The channel does not extend past the distal surface of the suture passage. The insert is configured to translate longitudinally within the channel between the proximal end of the anchor body and the distal surface of the suture passage.
