Method and apparatus for attaching tissue to bone, including the provision and use of a novel knotless suture anchor system
Apparatus for securing an object to bone, the apparatus comprising: an anchor, the anchor comprising: a body comprising an opening for receiving a filament therein; and a locking element movably mounted to the body for selectively locking the filament to the body; and an inserter for deploying the anchor in bone, the inserter comprising: a handle; an overtube extending distally from the handle; a carriage movably mounted to the handle; a shaft movably mounted within the overtube and connected to the carriage and releasably connected to the body of the anchor, the shaft being hollow; and a rod movably mounted within the shaft and connected to the locking element.
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.
TRICUSPID VALVE REPAIR USING TENSION
A method is provided for reducing tricuspid valve regurgitation of a patient. The method includes implanting a first tissue anchor at a first implantation site in cardiac tissue in the vicinity of the tricuspid valve of the patient, and implanting a second tissue anchor at a second implantation site in cardiac tissue of the patient opposite the first implantation site across the tricuspid valve. Using a spool that winds therewithin at least a portion of a longitudinal member that couples the first and the second tissue anchors together, tension is applied between the first and the second tissue anchors to alter the geometry of the tricuspid valve by rotating the spool.
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.
LATERAL PHARYNGEAL WALL TRACTOR AND IMPLANTATION METHOD
A lateral pharyngeal wall tractor comprises a bone fixer, a traction mechanism and a lateral pharyngeal wall fixer. The lateral pharyngeal wall fixer is fixed on an M. palatopharyngeus or other submucous tissues of a lateral pharyngeal wall. With the bone fixer fixed on a processus alveolaris or a hamulus pterygoideus or a processus pterygoideus as a supporting point, one end of the traction mechanism is connected to the bone fixer, the other end is connected to the lateral pharyngeal wall fixer, and as a result, the submucous tissue of the lateral pharyngeal wall is pulled outward. The elastic traction force produced by the traction mechanism is greater than the collapse force of the lateral pharyngeal wall which is produced by negative pressure during inspiration, but is less than the contraction force which is produced by the muscle of the lateral pharyngeal wall during deglutition.
IMPLANTED TONGUE SEPTUM FASCIA RETRACTION DEVICE AND IMPLANTATION METHOD
An implanted tongue septum fascia retraction device includes a fascia fixer, a pull line and a mandible fixer. The fascia fixer is fixed to a tongue septum fascia by means of a fixing clamp, a fixing hook or a fixing ring, and the mandible fixer is fixed to a mandible. One end of the pull line is connected to the fascia fixer, and the other end of the pull line is fixed to the mandible fixer. By adjusting the tightness of a pull line, a tongue septum fascia may be retracted forwards, thus pulling a falling tongue base forwards, opening an obstructed upper airway, and fulfilling the aim of treating snoring and obstructive sleep apnea/hypopnea syndrome (OSA) caused by glossoptosis.
Tendon stretching mechanism
A tendon stretching mechanism which engages the torn tendon using sutures. A second end of the sutures is exposed through the skin. Using a tensioning mechanism, a selectively pull is applied to the second end of the sutures to gradually stretch the tendon. This stretching of the tendon may take a week or more or until the tendon has been sufficiently elongated for reattachment to the bone. The tensioning mechanism is either manually operated or is automatic.
Self-Cinching Suture Anchors, Systems, and Methods
Various self-cinching suture anchors, self-cinching suture anchor systems, and methods of use are provided. In one exemplary embodiment, a suture anchor is provided that includes an outer member and an inner member configured to be received within the outer member. The inner and outer members can define a gap that allows a suture to be movably disposed within the outer member, e.g., within the gap, when the inner member is disposed within the outer member. The inner member can be configured to be secured within the outer member by a knot of the suture having a diameter greater than a width of the gap so as to fix the inner member within the outer member, while still allowing uni-directional tensioning of the suture.
System and method for pelvic floor procedures
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.
Method and apparatus for attaching tissue to bone, including the provision and use of a novel knotless suture anchor system
Apparatus for securing an object to bone, the apparatus comprising an anchor comprising a body comprising a passageway; and a movable element comprising a deformable portion; wherein the deformable portion is configured so that, (i) at a first level of force, the deformable portion restricts proximal movement of the movable element, and (ii) at a second, greater level of force, the deformable portion deforms and permits proximal movement of the movable element.
