SURGICAL TOOL AND METHOD OF USE
A surgical tool incorporates a suture guide with an anchor driver supporting an anchor where the anchor is maintained at a distance from the suture guide until release of a detent mechanism. Thereafter, the anchor is allowed to move into proximity to the suture guide, fixing a suture supported by the suture guide to a substrate, the entire procedure being achievable with a single hand.
Devices, systems, and methods for repairing soft tissue and attaching soft tissue to bone
Devices, systems and/or methods for repairing soft tissue adjacent a soft tissue repair site. In one embodiment, a repair device includes an anchor member, a capture member and one or more flexible members. The anchor member includes a base with at least four legs extending integrally from the base, the at least four legs configured to be moveable from a straight first position to a formed second position. The capture member is configured to be coupled to the anchor member such that the at least four legs of the anchor member move around structural portions of the capture member with the at least four legs of the anchor member in the formed second position. The one or more flexible members are coupled to the base of the anchor member, the one or more flexible members extending at least partially along the base of the anchor member.
Knotless self-locking anchor constructs and methods of tissue fixation
Systems and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair systems include self-cinching constructs with a fixation device, a flexible coupler and an optional shuttle/pull device attached to the flexible strand. An accordion-style weave region is formed by pulling on the shuttle/pull device subsequent to the fixation device being secured into the bone, to allow desired tensioning of soft tissue to be fixated or repaired relative to the bone and secured self-locking of the construct.
Knotless suture anchoring using two awl shafts
Methods and systems are provided for securing tissue to bone. A surgical system can include a driver having a proximal handle and a driver shaft extending therefrom, a distal awl shaft, a proximal awl shaft separate from the distal awl shaft and movable with respect to the distal awl shaft, a suture anchor, and a dilator feature distal to the suture anchor. The distal and proximal awl shafts are receivable in at least part of a lumen of the driver. In a bone forming configuration of the system, in which the distal awl shaft is driven into bone, a distal end of the proximal awl shaft abuts a proximal end of the distal awl shaft. The proximal awl shaft can be moved proximally, such as by activating an awl handle coupled thereto, with respect to the distal awl shaft to move the system in a suture anchor insertion configuration.
SUTURE ANCHOR
The present application relates to the field of medical devices, and in particular to a suture anchor. A suture anchor includes an anchor head and an anchor body, wherein a threading hole is formed on the anchor head, the anchor body includes a side pressing portion integrally formed by a plurality of layers of round tables, and at least two opposite longitudinal cuts are formed on each round table of the side pressing portion; from a direction close to the anchor head to a direction away from the anchor head, positions of the longitudinal cuts on adjacent round tables are deflected toward a same side.
METHOD AND APPARATUS FOR REATTACHING THE LABRUM TO THE ACETABULUM, INCLUDING THE PROVISION AND USE OF A NOVEL SUTURE ANCHOR SYSTEM
Apparatus for securing an object to bone, the apparatus comprising: an anchor assembly comprising an anchor and an actuation element extending from the anchor, wherein applying a force to the actuation element when the anchor is disposed in a hole formed in a bone secures the anchor to the bone; and an inserter for deploying the anchor assembly in a hole formed in a bone, the inserter comprising: a shaft for releasably engaging the anchor; and a force delivery mechanism mounted to the shaft and connected to the actuation element, the force delivery mechanism being constructed so as to receive an input force from an external source and to selectively apply an output force to the actuation element, with the force delivery mechanism being constructed so that the magnitude of the output force is limited regardless of the magnitude of the input force.
Epicardial anchor devices and methods
Apparatus and methods are described herein for anchoring a prosthetic heart valve. In some embodiments, an apparatus includes a tether attachment member that includes a base member that defines at least a portion of a tether passageway through which a portion of a tether extending from a prosthetic heart valve can be received therethrough. The base member defines a locking pin channel that intersects the tether passageway. A locking pin is disposable within the locking pin channel and movable between a first position in which the locking pin is at a spaced distance from the tether passageway, and a second position in which the locking pin intersects the tether passageway and can engage the portion of a tether disposed therein to secure the tether to the tether attachment member.
Suture-locking washer for use with a bone anchor, and method for supporting the thumb of a patient after basal joint arthroplasty, and other novel orthopedic apparatus and other novel orthopedic procedures
The invention provides surgical methods, devices, apparatus, and systems for supporting the thumb of a patient after basal joint arthroplasty. The embodiments of the invention comprise at least one index metacarpal anchor, at least one thumb metacarpal anchor, at least one sling for positioning the thumb metacarpal anchor relative to the index metacarpal anchor, and at least one anchor washer for tightening and securing the sling(s) without the need to tie the suture(s) components of the sling(s) into knots. Index and thumb metacarpal anchors comprise at least one bone-engaging element for engaging the respective metacarpal. The anchor washer may incorporate one or more sling-engagement mechanisms. Increasing the number of sling-engagement mechanisms associated with the anchor washer increases the surface area of the sling(s) and provides multiple sling elements to provide redundancy and increase the pull force of the sling(s) attachment(s) used to affix the thumb and index metacarpal anchors into a position relative to each other.
KNOTLESS SUTURE ANCHORING USING TWO AWL SHAFTS
Methods and systems are provided for securing tissue to bone. A surgical system can include a driver having a proximal handle and a driver shaft extending therefrom, a distal awl shaft, a proximal awl shaft separate from the distal awl shaft and movable with respect to the distal awl shaft, a suture anchor, and a dilator feature distal to the suture anchor. The distal and proximal awl shafts are receivable in at least part of a lumen of the driver. In a bone forming configuration of the system, in which the distal awl shaft is driven into bone, a distal end of the proximal awl shaft abuts a proximal end of the distal awl shaft. The proximal awl shaft can be moved proximally, such as by activating an awl handle coupled thereto, with respect to the distal awl shaft to move the system in a suture anchor insertion configuration.
TENSIONABLE AND LOCKABLE MICRO SUTURE ANCHORS AND ANCHOR ARRAYS FOR ANATOMICAL ATTACHMENT OF SOFT TISSUE TO BONE
A toggle-type suture anchor that incorporates individual suture tensioning and locking without knot tying. The anchor includes several exemplary designs of toggle bodies having a working suture pre-threaded through one or more passages therethrough. A locking suture loop is pre-threaded relative to the working suture and includes a collapsible loop that encircles a portion of the length of suture running longitudinally adjacent the side of the anchor. With the loop open, the working suture can slide through the anchor, however, when the loop is closed the working suture is locked in position to retain tension on the working suture. Alternatively, the locking suture loop can be replaced with a mechanical locking member that moves from a first unlocked to a second locked position. The exemplary anchors can be utilized in a pre-strung connected array of anchors.
