KNOTLESS ANCHOR INSERTION
Various exemplary systems and devices for knotless anchor insertion and methods of knotless anchor insertion are provided. In general, an inserter tool is configured for knotless anchor insertion in a soft tissue repair surgical procedure. The inserter tool is configured to insert an anchor into a bone of a patient to secure a soft tissue relative to the bone. A suture coupled to the soft tissue is secured relative to the bone by being trapped between an exterior surface of the anchor and a bone surface defining a hole in the bone in which the anchor is positioned.
Independent suture tensioning and snaring apparatus
In repairing soft tissue with a bone anchoring instrument (such as reattaching a tendon of a torn rotator cuff), the bone anchoring instrument may be used to anchor the soft tissue to a region of bone. The anchors inserted into the underlying bone may have one or more lengths of suture or wire attached thereto which may be tensioned independently of one another to affix the soft tissue to the bone by having a selector mechanism selectively engage and disengage ratcheted tensioning wheels from one another. Suture loading mechanisms may be employed for passing suture lengths into and/or through the anchors prior to deployment into the bone where such mechanisms may employ suture snares which are configured to reconfigure from an expanded shape through which suture lengths may be easily passed to a low-profile shape which secures the suture lengths within the snare.
Device for anchoring a suture
A device is for anchoring a suture to a bone. The device includes a suture engaged with an elastically deformable ring biased toward an unstressed state in which an outer diameter of the ring is D. The ring is compressible for insertion through a hole in a bone stabilization device having a diameter smaller than the diameter D.
Systems and devices for setting an anchor
An anchoring system and related methods are provided for treatment of dilated hearts and of functional valve regurgitation, the system comprising one or more self-expandable or manually expandable anchors and associated devices for fixating a valve splint within the heart. For example, a spade-shaped assembly may be configured to be deployed in a right ventricle of the heart and to stabilize a puncturing instrument to puncture the septum. Various puncturing instruments may also be part of the anchoring system, including one or more of a flexible needle having a multiplicity of slits disposed along the length of the needle, a trocar catheter with a retractable head, and a catheter needle having a blunt introducer to protect nearby tissue within the heart during advancing a guidewire. A cutter catheter and puncture location catheter may also be part of the system and be used during treatment.
Filamentary fixation device
One embodiment of the present invention includes a filamentary fixation system including a sleeve formed of filamentary material including an interior and an exterior surface along a length defined between a first end and a second end, the sleeve having a coating adapted to allow for tissue ingrowth, and a filament formed of filamentary material including a first free end and a second free end, and a length therebetween, at least a portion of the filament positioned within the interior of the sleeve.
DEVICE AND METHOD FOR ESTABLISHING AN ANCHORAGE IN TISSUE
A perforated sheath is anchored in a tissue opening with the aid of a tool, wherein the anchorage is achieved with the aid of mechanical vibration and a material which is liquefiable by the vibration. The tool includes a vibrating element and a counter element. Distal portions of both elements are introduced into the sheath to be in contact with each other at an interface. The vibrating element is connected to a vibration source and the vibrating element and the counter element are held against each other for effecting liquefaction of the liquefiable material at the interface. Under the effect of the force applied to the vibrating and counter element for holding them against each other, the liquefied material flows from the interface through the sheath perforation and penetrates the tissue.
Soft anchor assembly with non-sliding flexible strand and techniques for use
A soft anchor assembly according to an exemplary aspect of the present disclosure includes, among other things, a sheath, a first flexible strand affixed as non-sliding relative to the sheath and a second flexible strand slidable relative to the sheath.
SYSTEMS AND METHODS FOR ANCHORING AN IMPLANT
The invention relates in some aspects to a device for use in anchoring an implant, including anchors, sutures, implants, clips, tools, lassos, and methods of anchoring among other methods. Anchors as disclosed herein could be utilized to secure a coaptation assistance device, an annuloplasty ring, an artificial valve, cardiac patch, sensor, pacemaker, or other implants. The implant could be a mitral valve ring or artificial mitral valve in some embodiments.
METHOD AND DEVICE FOR SECURING BODY TISSUE
A suture and a suture retainer are positioned relative to body tissue. Ultrasonic vibratory energy is utilized to heat the suture retainer and effect a bonding of portions of the suture retainer to each other and/or to the suture. Portions of the body tissue may be pressed into linear apposition with each other and held in place by cooperation between the suture and the suture retainer. The suture retainer may include one or more portions between which the suture extends. The suture retainer may include sections which have surface areas which are bonded together. If desired, the suture may be wrapped around one of the sections of the suture retainer. The suture retainer may be formed with a recess in which the suture is received. If desired, the suture retainer may be omitted and the sections of the suture bonded to each other.
Devices and methods for occluding or promoting fluid flow
Devices and methods for occluding or promoting fluid flow through openings are disclosed. In one exemplary embodiment an occlusion device is provided having an expandable outer elongate tubular body, a guide member extending from a distal end of the outer body, and a slide tube disposed within the outer body, the proximal portions of the outer body and the slide tube being fixedly mated. The slide tube is configured to slide distally within the outer tubular body when the tubular body is expanded to form wings. A tether can be included as part of the device and it can be used to assist in positioning and locking a location of the device in an opening. Exemplary methods for delivering devices disclosed herein are also provided.
