Closure devices and methods
A method for closing a puncture in tissue that includes advancing a guide member into proximity with the tissue, the guide member having a needle guide, positioning a distal end of the guide member with the needle guide toward the tissue to present an opening of the needle guide toward the tissue the needle guide cooperating with a suture securing device that is slidably coupled to the guide member and a suture attached to the suture securing device, deploying the suture securing device, the suture securing device comprising a body with an anchor point for the suture and features that allow the suture securing device to pierce the tissue and resist retraction through the tissue, and establishing tension in the suture to move the suture securing device toward another suture securing device to thereby close the puncture in the tissue.
CONTINUOUS TETHERED TISSUE ANCHOR AND ASSOCIATED SYSTEMS AND METHODS
The invention relates to tissue anchor in medical procedures. More specifically the invention relates to a tethered anchor. Tethered anchor including a tether portion and an anchor portion that are continuously braided with one another, the tether portion extending continuously from the anchor portion; and the anchor portion having a greater width than a width of the tether portion.
Access site management system for percutaneous vascular access
The disclosure provides a dynamic vascular access and closure device for radial cinching of an access site. The device includes a tensioning tube, a resilient member disposed within the tensioning tube, and a plurality of sutures extending axially between a distal end of the tensioning tube and a proximal end of the tensioning tube. A proximal end of each of the plurality of sutures can be configured to attach to the resilient member such that movement of that suture causes compression or extension of the resilient member within the tensioning tube to provide cinching to the sutures.
Methods and devices for suture anchor delivery
A method for impacting a suture anchor into bone comprises providing an implantable suture anchor and providing an impactor device for impacting the suture anchor into the bone. The suture anchor is coupled to a distal portion of the impactor device. Positioning the suture anchor engages the anchor with the bone at an implantation site, and powering the impactor device impacts the suture anchor thereby implanting the suture anchor into the bone. The frequency of impaction is less than 20 KHz. The impactor device is then decoupled from the suture anchor, and the impactor device may be removed from the implantation site.
Device for Heart Repair
Disclosed herein is a catheter device (2) for implanting a leaflet anchor (10) and a papillary anchor (9) into the heart as part of a procedure for implanting an artificial chordae line (14) that extends between the leaflet anchor (10) and the papillary anchor (9), the catheter device (2) comprising: a two-part housing section extending from a distal end (8) of the catheter device (2) along the length of the catheter device (2) toward the proximal end (4) of the catheter device (2), the two-part housing section being arranged to be placed between the papillary muscle and a leaflet (12) of the heart during use of the catheter device (2), and the two-part housing section comprising a distal part (8) at the distal end of the catheter device (2) and a proximal part (4) located on the proximal side of the distal part (8); a leaflet anchor deployment mechanism at the proximal part (4) of the housing section for deploying a leaflet anchor (10) for attachment to the leaflet (12) of the heart; a papillary anchor deployment mechanism at the distal part (8) of the housing section for deployment of a papillary anchor (9) for attachment to the papillary muscle, wherein the papillary anchor deployment mechanism is arranged for deployment of the papillary anchor (9) by moving it outward in the distal direction relative to the distal part (4); and a flexible joint (34) located between the proximal part (4) and the distal part (8) of the two-part housing section, wherein the flexible joint (34) allows a centreline of the distal part (8) to be angled relative to a centreline of the proximal part (4).
DEVICES, SYSTEMS, AND METHODS FOR ADJUSTABLY TENSIONING ARTIFICIAL CHORDAE TENDINEAE IN A HEART
Devices, systems, and method for adjusting and setting tension of an artificial chordae tendineae. The artificial chordae tendineae is coupleable between a leaflet clip and a tissue anchor. A locking assembly, through which the artificial chordae tendineae extends, is shiftable between a tension-adjusting configuration, in which the artificial chordae tendineae is movable to adjust tension on the leaflet, and a tension-setting or locked configuration, in which the artificial chordae tendineae is inhibited or prevented or locked against moving with respect to the locking assembly to set or fix tension on the leaflet.
Method and devices for intracorporeal bonding of implants with thermal energy
The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.
SUTURE LENGTH ADJUSTMENT FOR MINIMALLY INVASIVE HEART VALVE REPAIR
Disclosed herein are various embodiments of suture adjustment mechanisms for anchors configured to be inserted into a heart wall of a patient to anchor a suture as an artificial chordae under an appropriate tension for proper valve function. Suture adjustment mechanisms can be configured to retain suture ends extending from the leaflet to the anchor with sufficient force to prevent natural movement of the leaflet from adjusting a length of the suture between the anchor and the leaflet. Free ends of the suture can extend from the anchor external to the body as tensioning strands. A surgeon can supply sufficient force on the tensioning strands from external the body to adjust a length and tension of the suture between the anchor and the leaflet.
Device for Heart Repair
Disclosed herein is an anchor system for implantation in body tissue to hold a line (18). The anchor system comprises an anchor (9), the anchor (9) comprising a number of hooks (62) for engagement with the body tissue and having a folded configuration and an unfolded configuration. The anchor (9) is made of an elastic material such that it can be elastically deformed into the folded configuration by application of a constraining force, and will return to the unfolded configuration when no constraining force is applied. The end of each of the hooks (62) comprises a tip (160′), wherein the tips (160′) are formed to curve towards a central axis of the anchor (9) when the anchor (9) is in the folded configuration.
Device for Heart Repair
An anchor (9) for implantation in body tissue (26) to hold a line (14) comprises a number of hooks (62) for engagement with the body tissue (26) and having a folded position and an unfolded position, wherein the anchor (9) is made of an elastic material such that it can be elastically deformed into the folded position by application of a constraining force, and will return to the unfolded position when no constraining force is applied, and wherein the hooks (62) are formed with openings (64, 66) along their length, wherein the openings (64, 66) in the hooks (62) comprise slits extending along some or all of the length of the hooks (62).
