    Abstract: A braided structure that includes a core and a sheath is provided. The core includes a yarn formed at least in part from an aromatic polymer (e.g., an aromatic polyester/liquid crystalline polymer or an aramid polymer), and the sheath, which includes a plurality of ultra high molecular weight polyolefin yarns, is braided around the core. The sheath has an overall diameter ranging from about 60 micrometers to about 650 micrometers. Despite its small diameter, the braided structure can be creep resistant and abrasion resistant while at the same time exhibiting low elongation, a high load at break, and high stiffness. The braided structure can be used in medical applications such as sutures, load bearing orthopedic applications, artificial tendons/ligaments, fixation devices, actuation cables, components for tissue repair, etc.

    Abstract: A fabric cutting system and/or method can include a mandrel having a body and first and second legs, a centered chuck, and an offset chuck, each chuck configured to receive either one of the legs or body to rotatingly support the mandrel between the chucks. When one of the legs is inserted into the centered chuck and the mandrel body is inserted into the offset chuck, the mandrel can be rotated and the fabric mounted on the mandrel can be cut about the leg at a location beyond the end of the other leg. One of the legs can include a leg extension removable from a leg base that when removed allows the other leg to be cut beyond the end of the leg base. The fabric can be cut with a cutting laser, which may be a multi-axis laser, and/or have low power.

    Abstract: A tip portion for a cautery device defining a device axis is provided herein. The tip portion comprises a first electrode and a second electrode spaced apart from one another. The tip portion further comprises at least one wire comprising a first end in electrical connection with the first electrode, a second end in electrical connection with the second electrode, and a central portion in electrical communication with the first portion and the second portion. The central portion of the at least one wire defines a cautery shape comprising a continuous perimeter extending in a cautery plane, wherein the cautery plane is perpendicular to the device axis. A retrieval portion may be provided to retain a cut portion produced during use of the cautery device.

    Abstract: A fabric can comprise yarns comprising less than about 30 denier total and less than about 10 denier per filament; a density of greater than about 177 yarns per cm2; and a thickness of less than about 3.2 mil. The fabric can further comprises a weight of less than about 60 g/m2. The fabric can have performance characteristics equivalent to or greater than those in conventional implantable fabrics. A method of making such a fabric can include twisting together filaments into a multifilament yarn; passing adjacent yarns into a loom in parallel so as to allow the yarns to be woven together more closely; maintaining a consistent tension on the yarns during placement of the yarns on a loom beam and during weaving; and or subjecting the fabric to increased heat and pressure so as to compress the yarns more tightly.

    Abstract: A continuous loop of material for use in mammals, particularly humans. One embodiment may have an air entanglement section therein and method of making the same. Another embodiment includes a hollow braided length having a first inner section and a second inner section, the sections formed by radially inserting the ends into the hollow braid and passing it along a portion of the hollow interior. These embodiments may also include a bone engagement member incorporated therein. A further embodiment is a loop assembly having a length of fiber, the length of fiber having two ends, and a bone engagement member having an end receiving member to securely receive the two respective ends therein.
