A suture construct having a soft button, defining a multiplicity of first apertures and a set of second apertures. Also, a suture loop assembly has a suture defining a lumen and forming a double loop, formed by a double trap having a first end and a second end, formed in a trap region of the suture, and in which a first portion of the suture is threaded through the trap region lumen from the first end to the second end and the first portion extends out from the second end, and a second portion of the suture is threaded through the trap region lumen from the second end to the first end, and the second portion extends out from the first end. Finally, the double loop passes through the set of second apertures of the soft button.

Soft button assembly and procedure

A suture assembly, including a button having two apertures and a suture defining a lumen and forming a double loop, formed by a double trap formed in the suture, opposed to the button, and in which a first portion of the suture is threaded through the lumen of the double trap and a second portion of the suture is also threaded through the lumen of the double trap, so that two portions of suture are positioned together in the double trap. The first portion of the suture, after emerging from the double trap, is threaded through the lumen again, thereby forming a second trap, increasing resistance of the double loop to expansion, the double loop being threaded through the apertures of the button, the suture having two suture ends that are threaded through the button apertures and accessible on a side of the button opposed to the double loop.

Method of performing a tendon replacement

A tendon repair suture tape comprising a flat braid of elastic, absorbable fibers and high strength fibers, the tape being at least 1 mm wide and 2 cm long, and less than 0.2 mm high. The suture tape includes at least 4 absorbable fibers and at least 4 high strength fibers. Further, the suture tape is capable of being stretched at least 10% from its shortest length to the length at which it breaks, presents an increasing resistance to further stretching as it is stretched, and is capable of withstanding a load of at least 260 Newtons before breaking.

Constructs and methods for repairing a tendon with a reduced risk of reinjury

A method of effecting a tendon repair in a patient comprising providing a suture tape, using the suture tape to connect tendon tissue to bone of the patient such that the suture tape lays flat on the tendon, and permitting ingrowth of the tendon tissue into the suture tape as the absorbable fibers are absorbed into the patient's tissue. The suture tape is a flat braid of elastic, absorbable fibers and high strength fibers, the tape being at least 1 mm wide and 2 cm long, and less than 1 mm high. The suture tape includes at least 4 absorbable fibers and at least 4 high strength fibers. Further, the suture tape is capable of being stretched at least 10% from its shortest length to the length at which it breaks and is capable of withstanding a load of at least 260 Newtons before breaking.

A method of sewing preserved animal tissue to a manmade work piece that forms a part of a prospective bioprosthetic heart valve. The method utilizes a needle having an attached suture length and also having a relative object visibility of less than 0.8 relative to a standard straight surgical needle. Also, this needle has a volume of less than 7 mmand a surface area of less than 70 mm, is formed entirely of 300 series stainless steel, and has an eye, and the suture length is threaded through the eye. The needle having an attached suture length is used to manually sew the animal tissue to the manmade work piece that forms a part of the prospective bioprosthetic heart valve, while maintaining sufficient optical closeness to maintain the visibility of the needle.

Fixation assemblies having a button captured by a continuous (i.e., closed) loop of thread, such as ultra high molecular weight polyethylene (UHMWPE) fiber are disclosed herein. Preferred assemblies are constructed such that the intact button cannot be detached from the continuous loop without breaking or opening the loop of fiber. The closed fiber advantageously contains at least one or two stitched, or otherwise secured or reinforced, sections positioned on the loop.

Method of making a continuous loop

A method of performing a tendon replacement, of a tendon connecting a first bone and a second bone, in an animal body utilizing a suture assembly that includes the following construction. A button has two apertures and a suture, engaged to the button, defines a lumen and forms a double loop, formed by a double trap that is opposed to the button. The suture assembly further defines a first single trap, and a third trap. In the method, a drill hole is drilled sequentially through the two bones. Also, a length of tendon tissue is draped over the loop and the button is passed through the drill hole through the first bone and the second bone and the button is oriented to sit on a surface of the second bone and the suture ends extend outwardly through the drill hole.

A one-way loop locking suture assembly, that includes suture material, defining a lumen, with the suture material being comprised of a first terminal portion extending from the first end to a first broaching point, a medial portion extending from the first broaching to a second broaching point and a second terminal portion extending from the second broaching point to the second end. The first terminal portion enters into the lumen of the medial portion at the second broaching point, extends through the lumen of the medial portion and exits the lumen of the medial portion through the first broaching point, thereby forming a loop, wherein the medial portion includes the first terminal portion extending through the lumen of the medial portion. Accordingly, when the loop is tightened about a pair of pins, the lumen of the medial portion narrows, thereby retaining the first terminal length and preventing loosening.

Suture locking loops and method of use

A suture assembly, including a button having two apertures and a suture defining a lumen and forming a double loop, formed by a double trap having a first end and a second end, opposed to the button. A first portion of the suture is threaded through the trap from the first end to the second end, and a second portion of the suture is threaded through the trap from the second end to the first end. The assembly further defines a first single trap, in which the first portion of the suture is threaded through the lumen between the second end and the button. Also defined by the assembly is a third trap, in which the second portion of the suture is threaded through the lumen between the first end and the button. Finally, the double loop is threaded through the two apertures of the button.
