  • Patent number: 8834763
    Abstract: The present disclosure relates to a method of forming fibers. First and second precursors, each possessing a core and at least one functional group known to have click reactivity, are mixed in a hopper. The mixed precursors are then extruded through an extrusion die to crosslink and produce a filament. Polymerization of the first and second precursors is catalyzed by transition metal ions.

  • Patent number: 8684250
    Abstract: An apparatus for forming an anastomosis between adjacent intestinal sections of tissue is provided. The apparatus includes a circular surgical stapler having an anvil assembly with an anvil shaft and an anvil, the circular surgical stapler further having a tubular body portion with an annular knife and a body portion shaft selectively attachable to the anvil shaft; and a seal structure for deposition between the intestinal sections of tissue including a hub configured to engage attachment structure on at least one of the anvil shaft and the body portion shaft. The attachment structure is positioned so that the seal structure is located between the intestinal sections of tissue when the circular surgical stapler is disposed within the intestinal sections of tissue.

  • Patent number: 8679157
    Abstract: Barbed surgical sutures are provided which include an elongated body and a plurality of barbs extending therefrom. A bioactive agent is disposed within barb angles formed between the barbs and the elongated body. The barbs may be made from a shape memory polymer having a permanent shape which may be deformed to a temporary shape, such that barbs of the suture extend at different barb angles in the different shape configurations. The barb angles of the permanent shape may be greater than the barb angles of the temporary shape, thereby exposing and/or releasing a bioactive agent after placement in tissue.
