Fixation device for securing a linear element to a workpiece
A fixation device for securing a linear element to a workpiece includes a contact component and a fixation component. The contact component typically includes (i) a first contact surface for application to a workpiece and (ii) a first opening for receiving a linear element. The fixation component typically secures a portion of the linear element on a side of the first contact component opposite the first contact surface. The fixation component engages the contact component to prevent passage of the linear element's secured portion through the workpiece when a tension is applied to the linear element in a direction opposite the contact surface.
LOOP/ BUTTON SYSTEM FOR TENDON AND LIGAMENT RECONSTRUCTION
The invention relates to a medical implant (1), comprising at least a first cortical fixation device (200) for fixing a ligament or tendon graft (G) in a desired position, wherein said first cortical fixation device (200) comprises a body (201) having a front side (201a) and a rear side (201b), which rear side (201b) faces away from the front side (201a), and wherein said body (201) comprises a first and an adjacent second through-hole (210, 211), which through-holes (210, 211) extend from the front side (201a) to the rear side (201b) of said body. According to the invention the medical implant (1) further comprises a first suture thread (100) extending through the through-holes (210, 211) and forming a twisted loop (104) and a non-twisted loop (105) on the front side (201a) of the body (201), and a sliding knot (108) on the rear side (201b) of the body (201), and wherein the medical implant (1) comprises a second suture thread (300) extending through the sliding knot (108).
Method and apparatus for closing a fissure in the annulus of an intervertebral disc, and/or for effecting other anatomical repairs and/or fixations
Apparatus for attaching a suture to an object, the apparatus comprising: an anchor comprising a body having a distal end and a proximal end, and a vertical bore extending through the body substantially perpendicular to the longitudinal axis of the body; wherein the anchor further comprises a recess formed on one side of the body and a U-shaped slot formed on the opposing side of the body, whereby to form a flexible finger extending distally within the body, and further wherein the distal end of the finger is spaced from an opposing portion of the body; and wherein at least one of the flexible finger and the body comprises a cutout extending therethrough, with the cutout cooperating with the U-shaped slot and the recess so as to together form a suture loading hole extending through the body, with the suture loading hole being sized to receive a suture therein.
Bone anchor having improved fixation strength
Bone anchors having improved fixation are discussed. The bone anchors include an anchor body and radially protruding ribs that extend approximately parallel to a longitudinal axis of the bone anchor. A leading distal edge of each rib may be configured in a tapered knife-edge configuration. Such ribs may mitigate the plow-out effect, preserving contact between the ribs and the surrounding bone along the length of the anchor. Furthermore, such ribs provide increased surface area, improving fixation strength.
Flush anchor snap-off apparatus
An anchor for tensile member(s) includes: a housing having a hollow interior; a collet in the hollow interior of the housing, the collet having a peripheral wall defining a central bore and an exterior surface. The collet is configured to be swaged around the tensile member(s). The collet includes longitudinal grooves in an outer surface of the peripheral wall, each defining a web configured to collapse inward in response to external compressive force. A sleeve has a peripheral wall defining interior and exterior surfaces and is disposed in the housing axially adjacent to the collet. At least one of the collet and the sleeve is tapered and the sleeve and the collet are arranged such that sleeve movement from a first position to a second position will cause the sleeve to bear against the collet, swaging the collet radially inwards around and against the tensile member(s).
SUTURE LOCKING DEVICES FOR PERFORMING TENSIONABLE KNOTLESS SURGICAL PROCEDURES
Systems and methods are provided for performing tensionable knotless surgical procedures. A suture locking device that includes a one-way locking mechanism may be utilized for tensioning and locking one or more strands of suture during the surgical procedure. The one-way locking mechanism may be established by one or more locking barbs of the suture locking device.
KNOTLESS SUTURE ANCHOR WITH UNTHREADED NOSE
A suture anchor has a tubular body having an axial bore therethrough with one or more purchase enhancements on an exterior surface of the body adapted to enhance purchase of the body within a bone hole. These are preferably screw threads. A distal nose of the suture body has a smooth exterior surface. A length of suture passes down along the exterior surface over the purchase enhancements, over the distal nose, and up into the bore. The smooth exterior surface of the distal nose allows tension of the suture to be held by the engagement of the nose within the bone hole thus making it easier to obtain proper tension as the remaining portion is engaged into the bone hole to provide final fixation.
Minimally invasive repair of heart valve leaflets
A method of repairing a heart valve provides intravascular access for repair of a heart valve through a ventricular trans-septal approach. An external guide catheter can be inserted through a vein of a patient into the right ventricle via the right atrium. An internal guide catheter can be inserted through the external guide and can provide access to the septum for a puncture tool to create an opening through the septum to the left ventricle. The internal guide can then be advanced into the left ventricle and used to guide a deployment catheter that deploys a repair device onto the heart valve.
DEVICES, SYSTEMS AND METHODS FOR TREATING BENIGN PROSTATIC HYPERPLASIA AND OTHER CONDITIONS
Devices, systems and methods for compressing, cutting, incising, reconfiguring, remodeling, attaching, repositioning, supporting, dislocating or altering the composition of tissues or anatomical structures to alter their positional or force relationship to other tissues or anatomical structures. In some applications, the invention may be used to used to improve patency or fluid flow through a body lumen or cavity (e.g., to limit constriction of the urethra by an enlarged prostate gland).
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.
