TIE SYSTEMS FOR STERNAL CLOSURE
A sternal tie assembly having a pair of hook-shaped needles, a length of sternal tie extending from a proximal end of each of the needles, and a pair of posterior plugs, each of the posterior plugs being slidably mounted on the tie and tethered, via suture material, to the proximal end of a respective one of the needles. A method of use of the sternal tie assembly includes creation of a hole or channel in sternum, manubrium, rib, rib cartilage, intercostal muscle, or other tissue, drawing a portion of the tie and the suture material through the channel formed in the tissue by the needle, severing the needle from the tie and suture material, continuing to advance the suture material until a post of each of the posterior plugs is pulled into the respective channel in the tissue, or at least until a head of the plug is disposed against the channel in the tissue, then threading an anterior plug onto each exposed end of the sternal tie, securing the anterior plugs into respective anterior openings in the tissue, then crossing and twisting the sternal tie ends together until the tissue ends are closed together.
TENDON REPAIR SYSTEM
A system for coupling a tendon to a bone may include a tendon coupling device engageable with a tendon, a fastener to secure the tendon coupling device to the tendon, a bone coupling device, and a flexible element. The flexible element may include a first portion and a second portion. The first portion of the flexible element may be couplable with the fastener to securably attach the flexible element to the tendon. The bone coupling device may include a bone-facing surface engageable with a surface of the bone proximate a bone tunnel formed through the bone, and a hole formed through the bone coupling device. The second portion of the flexible element may be receivable through the bone tunnel and the hole formed through the bone coupling device to engage an opposing surface of the bone coupling device and securably couple the tendon to the bone.
Mechanical mesh fixation device and curvilinear tack system
Devices and methods for affixing reinforcing material to a fascial incision in an abdominal wall to reinforce and augment closures thereof. The device includes first and second arms, each having a proximal end and a distal end extending away from a housing with a length therebetween. The distal end of the first arm is spaced from the distal end of the second arm such that the first and second arms are engageable with reinforcing material on opposing sides of a fascial incision. One or more fixation elements are deployable from the distal end of at least one of the first and second arms to affix the reinforcing material on opposing sides of the fascial incision.
HOLLOW TWO-SECTION IMPLANTATION KNOTLESS SUTURE ANCHOR
The present invention pertains to a hollow two-section implantation knotless suture anchor which comprises a main body, a tightening element and a taper. The main body comprises a front part, a rear part, a middle part, a first penetration part, a first accommodation space, a first thread, a tapered structure, and a perforation. The tightening element comprises a second penetration part and a second accommodation space. The taper comprises a taper body and a taper head. Moreover, the suture can pass through the perforation on the outside of the main body through the perforation. Afterthat it can pass through the first accommodation space and then the second accommodation space on the outside of the tightening element from the side of the tightening element opposite to the main body. Finally, it can extend on the outside of the main body. Hence, by pulling the ends of the suture, the tightness of the suture tightened by the tightening element and the front part is adjustable. Also, when the taper body of the first penetration and the second penetration is positioned, the taper head is next to the tightening element. Thus, by rotating the taper, both the main body and the tightening element are rotatable.
KNOTLESS TENSIONABLE FIXATION SYSTEMS AND SURGICAL METHODS FOR REPAIRING TISSUE DEFECTS
A knotless tensionable fixation system may be utilized for performing surgical methods for repairing tissue defects within a joint. An exemplary surgical method may include fixating a graft over top of the tissue defect with the knotless tensionable knotless fixation system. The knotless tensionable fixation system may include a plurality of knotless suture anchors, the graft, and a reinforcement construct. The reinforcement construct may establish a fixed segment of material over the graft after being secured in place by the plurality of knotless suture anchors.
Hair implants comprising enhanced anchoring and medical safety features
A hair implant suitable for subcutaneous implantation is provided having an anchor comprising an anchor body, and at least one collagen receiving structure selected from the group consisting of at least one tunnel disposed through the anchor body and an external surface feature of the anchor body. The anchor further comprises at least one hair strand projecting from a distal end of the anchor body, wherein the at least one collagen receiving structure is configured to support collagen ligature growth after subcutaneous implantation of the hair implant so as to anchor the anchor to a hair implant recipient, and the collagen receiving structure is free of hair.
Tensionable knotless anchors and methods of tissue repair
Surgical devices and methods of tissue repair using tensionable knotless fixation devices. A flexible material (for example, suture or suture tape) may be attached to the fixation device. A flexible material may be threaded through an eyelet of a tip provided as part of a swivel anchor assembly to provide added stability to the fixation devices.
Coaptation enhancement implant, system, and method
Implants, implant systems, and methods for treatment of mitral valve regurgitation and other valve diseases generally include a coaptation assist body which remains within the blood flow path as the leaflets of the valve move, the valve bodies often being relatively thin, elongate (along the blood flow path), and/or conformable structures which extend laterally from commissure to commissure, allowing the native leaflets to engage and seal against the large, opposed surfaces on either side of the valve body during the heart cycle phase when the ventricle contracts to empty that chamber of blood, and allows blood to pass around the valve body so that blood flows from the atrium to the ventricle during the filling phase of the heart cycle. Separate deployment of independent anchors near each of the commissures may facilitate positioning and support of an exemplary triangular valve body, with a third anchor being deployed in the ventricle. An outer surface of the valve body may accommodate tissue ingrowth or endothelialization, while a fluid-absorbing matrix can swell after introduction into the heart. The valve body shape may be selected after an anchor has been deployed, and catheter-based deployment systems may have a desirable low profile.
Non-invasive suture anchor and method
A non-invasive device for anchoring a suture includes a sheet to which a suture can be attached and an adhesive that can affix the sheet to bone. The method provides placing effective amount of an adhesive on a bone and attaching the suture to the adhesive and allowing the adhesive to set.
Suture methods for forming locking loops stitches
Methods for suturing tissue by forming a locking loop of suture material. In particular, method of using a suture passer to arthroscopically create a locking loop of suture in difficult to access tissues. As used herein a locking loop of suture is a loop of suture that is passed through a tissue from a first side to a second side of the tissue; one or more of the legs of the loop extending from the first side are passed through the tissue to the second side of the tissue and are then passed through the loop, and the loop is cinched to tighten closed over the one or more legs. The resulting locking loops stitches are extremely strong and distribute the stresses across the tissue in a desirable manner.
