  • Patent number: 10213292
    Abstract: Some materials used to make anchors for soft tissue repair, for example, have beneficial properties, including stiffness, bioabsorbability, and osteoconductivity. These materials, however, are not flexible and are challenging to make flexible wings out of for winged anchors. Wing flex is desirable for achieving high fixation strength in winged anchors. Accordingly, an anchor is provided having a hybrid structure including a core body made from a biocomposite, bioabsorbability, osteoconductivity or biocompatible non absorbable material and a wing assembly made from different and more flexible material. Examples of the hybrid anchor take advantage of properties of the different materials strategically placed. A no-hole-prep example of the hybrid anchor reduces the time to install the anchor. A modular example of the hybrid anchor provides a customizable anchoring solution to meet a variety of diverse clinical needs.

  • Publication number: 20190015767
    Abstract: Regeneration of a fluid medium can be accomplished using a continuously regenerable scrubber, which, in its various embodiments, combines valve functions and sorbent material, such as amine beds, into one component, dramatically reducing size and mass of scrubber. Sorbent material beds rotate continuously past breathing gas vent loop ports for scrubbing CO2/H2O and then past vacuum ports for regenerating the sorbent material. Typically, a first fluid output is connected to a lower header fluid output and a second, sweeping fluid source connected to a lower header fluid input. A motor spins the substantially circular bed assembly at a predetermined speed which allows adsorption or absorption as well as desorption of materials flowing through the sorbent material.

The distal end of the suture bridge has a thickness greater than a thickness of the proximal end of the suture bridge. At least two ribs extend from the proximal end of the suture bridge to a proximal end of the anchor. At least one open helical coil wraps around the at least two ribs and extends, substantially, from the proximal end of the suture bridge to the proximal end of the anchor. The at least one open helical coil defines an internal volume communicating with a region exterior to the anchor through apertures between turns of the at least one open helical coil. The at least two ribs are engagable with a grooved shaft of a driver.
