Method for tissue fixation
A method for securing a strand to a fixation member for arthroscopic fixation, wherein the fixation member includes a channel on an exterior surface and an aperture therethrough. The method includes passing a strand having first and second ends through a flexible sleeve, passing the sleeve through the aperture of the fixation member in a first direction, tensioning the strand, and pulling the sleeve in a second direction different than the first direction to secure the sleeve to the fixation member without tying the strand on the fixation member.
SURGICAL FILAMENT SNARE ASSEMBLIES
A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose with first and second noose limbs connected, preferably slidably connected, to the filament engagement feature of the anchor. The first and second noose limbs emerge from the anchor as first and second free filament limbs which are capable of being passed through tissue to be repaired and then passable through the noose. The noose, such as one or more half-hitches, is capable of receiving the free filament limbs and strangulating them when tension is applied to at least one of the free filament limbs and the noose to enable incremental tensioning of the tissue after the anchor is fixated. Preferably, the snare assembly further includes a flexible sleeve joining at least some portion of the first and second free filament limbs to facilitate passing of the free filament limbs at least through the tissue as a single unit.
KNOTLESS SUTURE ANCHOR
Methods and devices are provided for anchoring suture to bone. In one exemplary embodiment, a suture anchor is provided that includes a proximal component, a distal component, and an intermediate component positioned between the distal component and the proximal component. The proximal and distal components can each be configured to move independent of one another and to move relative to the intermediate component. In this way, the proximal, intermediate, and distal components of the suture anchor can be configured to cooperate with one another to prevent removal of the suture anchor from a bone hole in which the suture anchor is disposed and to lock a suture relative to the suture anchor and to the bone hole.
Knotless suture anchor and methods of use
Various devices, systems and methods for knotless suturing of tissue are disclosed. These devices allow sutures to be anchored to bone, and more specifically provide a suture anchor which eliminates the need for knotting the suture. Thus, damaged tissue may be re-attached to a substrate tissue. The anchors have a minimum of moving parts may be suited to being a single molded polymer construction. The anchors will find particular utility in hip and shoulder arthroscopy, e.g. labral re-attachment and similar procedures.
SUTURE ANCHOR
An anchor device and system for coupling soft tissue to osseous tissue includes a stopper member that supports a loop of suture material. A fixing member includes features that allow it to be rigidly coupled to surrounding bone and thus hold the stopper member in a cavity within the bone. The loop of suture material, in turn, supports a second suture device, which is coupled to, and thus retains, the soft tissue. In certain embodiments, the fixing member includes a wadding structure having a generally elastic property.
Corkscrew tissue anchor
A tissue anchor includes a driver head associated with a proximal portion of the tissue anchor, a pointed tip portion associated with a distal portion of the tissue anchor, a tissue-engagement portion disposed between the driver head and the pointed tip portion, and a cover configured to cover at least a portion of the tissue-engagement portion.
Suture passer systems and methods for tongue or other tissue suspension and compression
Suture passer systems for tissue suspension and tissue compression, and more particularly for tongue suspension, are described. The system can include at least a first elongate tubular body or shaft, a needle having a lateral bias carried by the elongate body, and a retrieval element operably connected to the elongate tubular body. The needle can have a substantially straight configuration when located within the elongate tubular body, and be configured to exit an opening at or near a distal end of the elongate tubular body and assume a laterally biased or curved shape to form a path through tissue. The needle is configured to carry a suture. The retrieval element can be configured to retrieve the suture carried by the needle after the needle has formed a curved or otherwise angled path through tissue. The system can also include one or more bone anchors to secure the suture loops. Methods of placing one or more suture loops into tissue, such as the base of the tongue, are also described.
KNOTLESS IMPLANTS, INSTRUMENTS, AND METHODS
A suture anchor and methods of use thereof are disclosed. The suture anchor comprises an anchor body having a slot formed in the body and a passage extending through the body in a first direction. The passage is sized to permit a suture to traverse the body through the passage. The suture anchor also has a shaft with a sharp portion, and the slot and the passage intersect within the anchor body. The shaft is movable relative to the anchor body within the slot from a first position in which the sharp portion and the passage do not intersect, to a second position in which the sharp portion and the passage intersect. The shaft can penetrate a suture or multiple suture strands to fix the suture or suture strands relative to the suture anchor.
ANCHORING DEVICE AND METHOD FOR ACCURATE POSITIONING AND INSERTION OF AN ANCHOR ASSEMBLY
An anchoring device including a finger-mountable work channel defining assembly defining a finger mounting axis and a work channel axis angled with respect to the finger mounting axis, the finger-mountable work channel defining assembly defining an aperture lying generally in an aperture plane angled with respect to the finger mounting axis and with respect to the work channel axis, an anchor insertion assembly arranged for limited axial displacement along the work channel axis with respect to the aperture so as to intersect the aperture plane and an anchor assembly including at least an anchoring portion and a flexible elongate portion attached thereto, the anchoring portion having a pre-anchoring operative orientation and an anchoring operative orientation.
Surgical Constructs for Tissue Fixation and Methods of Tissue Repairs
Surgical constructs, assemblies and methods of tissue fixation are disclosed. A surgical construct includes a spreadable web attached to a plurality of peripheral strands. The spreadable web may be tensionable and may include one or more flexible filaments or strands. At least one of the filaments is coupled to the peripheral strands. The filaments may extend from the peripheral strands in different directions and/or orientations. The spreadable web is expandable and can be adjusted to various widths. The spreadable web may be knotless. The spreadable web may be tensionable. The surgical construct may be attached to one or more knotted or knotless fixation devices
