  • Colored suture construction
    Patent number: 9474520
    Abstract: A colored suture includes an elongate woven braid of filaments including one or more ends made of an ultra high molecular weight polyethylene (UHMWPE). The suture also includes second and third ends which can be colorable or dyeable before or after incorporation into the elongate woven braid. This invention provides surgeons with improved recognition of suture ends in surgery by construction of a bi-colored co-braid with at least two ends of different color schemes or patterns braided into a UHMWPE construction. One of the colored ends runs continuously from one end of the suture to the other end. The other colored end can be colored only on one half of the end. This provides a suture with two distinguishable ends, while still maintaining a continuous line of color along the length of the suture.

  • Ligation clip with flexible clamping feature
    Patent number: 9445820
    Abstract: A polymeric surgical ligating clip is provided having curved leg members joined by a resilient hinge. A leg member includes a flexible rib protruding from a vessel clamping inner surface and extends longitudinally between the proximal and distal end portions of the leg member. The flexible rib defines a channel extending transversely through the rib along a majority of said length. The flexible rib can collapse and provides better retention of the clip on a vessel. The clip can contain a flexible rib on both legs in an interlocking fashion. Or a plurality of teeth can protrude from a second vessel clamping inner surface of a second leg member. The plurality of teeth can include first and second rows of teeth extending longitudinally on the second leg member, transversely separated from each other on opposite sides of a centerline of the clip.
