One-way adjustable loop suture constructs and methods of forming and using the same
Surgical constructs and methods of use for a one-way adjustable fixation loop are formed by tying two knots in a surgical filament, each knot defining an individual adjustable loop and the individual adjustable loops being interconnected to form the one-way adjustable fixation loop. The knots enable a non-spliceable suture to be used in the creation of the one-way adjustable fixable loop. Embodiments can include a fixation device, such as a cortical button or plate for use in a bone tunnel, and enable the knots to work independent of and suspended below the fixation device. Embodiments can increase the compatibility of the adjustable fixation loop with existing fixation devices and can isolate and protect the knots from damage during use and after implantation.
HIP CAPSULE CLOSURE
Systems and methods of repairing tissue are disclosed. Systems and methods may repair an opening through a hip capsule. Systems and methods preferably repair the tissue while minimally encroaching on the tissue immediately behind the repair, such as the hip joint tissues. Some systems may repair the tissue with a suture passer having a needle that slides in axial alignment with the passer and includes a first recess for passing the suture in a first axial direction and a second recess for passing the suture in an opposing axial direction. Some systems may pass a portion of a repair construct in a retrograde direction, placing the repair construct in a preferred arrangement accommodating for the stresses on the tissue.
Method and apparatus for coupling soft tissue to a bone
A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. The apparatus includes a member to pull the soft tissue implant into a femoral tunnel. The member includes a suture having first and second ends which are passed through first and second openings associated with the longitudinal passage to form a pair of loops. A collapsible tube is positioned about the suture. Application of tension onto the suture construction causes retraction of the soft tissue implant into the femoral tunnel and the collapse of the tube to form an anchor.
METHOD AND APPARATUS FOR COUPLING ANATOMICAL FEATURES
A method of coupling a first portion of an anatomy to a second portion of the anatomy includes coupling first and second bones of the anatomy with a bone-tendon-bone implant. The bone-tendon-bone implant has a first bone end, a second bone end and a replacement tendon between the first and second bone ends. The first and second bone ends are positioned in corresponding first and second bores of the first and second bones. The first bone end is secured to the first bone with a first bone anchor. A second anchor coupled to the bone-tendon-bone implant is passed through and outside the second bore. The second anchor is coupled to an adjustable suture construct having two adjustable suture loops. Tensioning at least one of first and second ends of the adjustable suture construct tensions the replacement tendon and positions the first bone relative to the second bone.
SURGICAL KNOT ASSEMBLY FOR TYING A SURGICAL KNOT
A surgical knot assembly for tying a surgical knot is disclosed. The surgical knot assembly for tying a surgical knot includes an outer tube, an inner tube slidably interconnected within the outer tube and having a distal end protruding from the outer tube as a neck and a strand of suture material having a portion of a length configured as pre-tied knot and a loop. The loop is adapted to receive at least a strand of suture filaments therein, and fastening of the loop, the pre-tied knot and the suture filament to form a surgical knot. While the inner tube is retracted, the loop is closed to hold the at least one suture material and receive the at least one suture filament to form the surgical knot successfully.
Transcatheter atrio-ventricular valve prosthesis
A transcatheter atrio-ventricular valve prosthesis for functional replacement of an atrio-ventricular valve in a connection channel, having a circumferential connection channel wall structure, between atrial and ventricular chambers of a heart, including an inner device to be disposed in the interior of the connection channel, the inner device having a circumferential support structure which is radially expandable and having a valve attached to the circumferential support structure, and an outer device to be disposed on the exterior of the connection channel, wherein the outer device at least partly extends around the inner device at a radial distance to the inner device, wherein the inner and outer devices form a securing mechanism for securing the circumferential connection channel wall structure therebetween.
TENODESIS ANCHOR
A tenodesis anchor having an anchor member coupled to at least one fiber loop. The anchor member is inserted into a bone and the loop closed about a tendon to be anchored to the bone. Closing the loops additionally deforms the anchor member so that it remains within the bone, thereby securing the tendon trapped in the loop to the bone without the use of a staple.
BENIGN PROSTATIC HYPERPLASIA TREATMENT DEVICE
A benign prostatic hyperplasia treatment device. The benign prostatic hyperplasia treatment device includes: an anchor assembly including a pair of first and second anchors arranged at upper and lower portions of the outer surface of the prostate gland, and a ligature connecting the first and second anchors with each other so that the first and second anchors continuously compress the prostatic tissues to secure the opening of the prostatic urethra; a sheath inserted into the urethra and having a needle, which guides the anchor assembly to be deployed at the prostate gland; a needle manipulation part for manipulating movement of the needle so that the needle is deployed through an end portion of the sheath.
METHOD AND APPARATUS FOR COUPLING ANATOMICAL FEATURES
A method of coupling a first portion of an anatomy to a second portion of the anatomy includes coupling first and second bones of the anatomy with a bone-tendon-bone implant. The bone-tendon-bone implant has a first bone end, a second bone end and a replacement tendon between the first and second bone ends. The first and second bone ends are positioned in corresponding first and second bores of the first and second bones. The first bone end is secured to the first bone with a first bone anchor. A second anchor coupled to the bone-tendon-bone implant is passed through and outside the second bore. The second anchor is coupled to an adjustable suture construct having two adjustable suture loops. Tensioning at least one of first and second ends of the adjustable suture construct tensions the replacement tendon and positions the first bone relative to the second bone.
Apparatus and method for suturing body lumens
A medical apparatus that includes a distal member, a needle disposed in the distal member and proximally advanceable from the distal member, and a needle capture portion positioned proximal to the distal member and which includes a through-hole to direct the needle from the needle capture portion towards a graspable member at a trajectory narrower than a trajectory of the needle from the distal member to the needle capture portion.
