Sutures and Suture Assemblies:
Sutures are one of the most critical products used for tissue repair, stabilization and fixation, actuation and delivery, and even component assembly. They can be constructed in two primary formats: monofilaments and multifilament braids. The choice of which should be used is highly dependent upon the clinical application and surgery type. ATEX Technologies creates custom configurations that can achieve very specific performance and physical attributes necessary for the finished device to perform successfully throughout its designated lifespan. By leveraging our custom braiding technology, we are able to configure braids that cover the standard USP size range, and more. ATEX Technologies is also able to intermingle disparate materials to improve visibility of the material during surgery and to impart very specific handling and performance criteria. In particular, we are able to incorporate our proprietary UHMWPE and LCP fibers into braids along with our in-house extruded PET in ways that provide just the right tensile strength, elongation, surface characteristics and visibility. In addition to providing either cut or spooled length sutures, we can also attach your preferred needle creating suture assemblies that will also meet required needle attachment strength criteria. Sutures and braids can also play an important role in device delivery in minimally invasive surgeries.
Cables and Tethers:
Similar to sutures, braided cables and tethers are complex braided yarns that are used for applications that require significant strength or load bearing capability. Cables and tethers are often made with high strength materials such as UHMWPE or a mixture of UHMWPE and PET and can be braided in a round or flat tape pattern. In addition, cables and tethers can be made with a terminal bifurcation or even loops to facilitate even greater ease of use. Often used to stabilize structures and add strength to damaged tissue after a major repair as seen in an allograft placement or fracture repair. Polymeric cables can be used to hold structures in place safely to allow for healing. High strength cables and tethers can also be used as actuation cables in deployment devices or short term implantables.
Surgical mesh is typically a flat, open textile that often is used to reinforce bone or tissue and can play a role in promoting healing by allowing for cellular ingrowth. Surgical meshes can be knits or weaves, the choice of which is dependent on the application and the particular performance and physical features the material will need to exhibit. ATEX Technologies can manufacture mesh using our own proprietary PET or with other materials including bioresorbables. Although surgical mesh is often used in flat, cloth or ribbon-like configurations, it can also be engineered in the form of a tube. This format is often used in stabilization applications.
Tissue scaffolds are textiles that act as matrices for cellular growth and are critically important in the fields of tissue engineering and regenerative medicine. Scaffolds, made from polymeric material, provide a framework that cells can attach to and proliferate. Commonly associated with non-wovens, the unique patterns of the scaffold structure can be engineered to be highly attractive to anchor-dependent cells. At ATEX, we can control the shape, elasticity, rigidity and surface characteristics of the scaffold so that we can optimize the matrix for specific cell growth requirements.
One of ATEX Technologies’ newest offerings, pledgets play a supporting role in wound management along with surgical sutures and suture assemblies. These non-woven felt pads act as tissue supports, protecting underlying tissue from the tension of the suture because it tends to distribute the tension of the suture across its surface. In addition, the pledget itself allows for optimal tightening of the suture. Pledgets at ATEX can be fully customized and can be manufactured from our proprietary PET and PTFE fibers intended specifically for use in medical applications.
