  • Publication number: 20220395288
    Abstract: A method of suturing a trocar path incision in a tissue of a patient with an obturator includes inserting the obturator through the tissue such that a shaft of the obturator extends through a tissue opening about the trocar path incision and a distal tip of the obturator is positioned within a cavity of the patient. The method also includes directing the suture via a suturing feature with the obturator inserted through the tissue in order to direct the suture relative to the tissue. Furthermore, the method includes closing the tissue opening about the trocar path incision with the suture.

  • Patent number: 10869690
    Abstract: An obturator configured for use with a trocar includes a head and a distally extending shaft configured to be received within a working channel of a trocar. The obturator further includes a distal tip configured to puncture tissue, first and second needle entrance ports each arranged on at least one of the head or the shaft, and first and second needle exit ports arranged on the shaft. The first and second needle entrance ports communicate with the first and second needle exit ports, respectively, to define respective first and second suture paths extending obliquely to the central axis. Each of the first and second suture paths includes at least one sealing element. In some examples, the obturator further includes at least one deployable member coupled to the shaft and configured to project radially outwardly in a deployed position.

  • Patent number: 8142805
    Abstract: Disclosed are implantable tissues including one or more enzyme inhibitors bound in the tissues, bioprostheses including the tissue, and methods for incorporating enzyme inhibitors in implantable tissues. Disclosed tissue can exhibit increased resistance to degradation, and specifically, degradation due to enzyme activity following implantation. Moreover, the disclosed methods can lead to increased levels of beneficial components bound in implantable tissues following a fixation/stabilization protocol. Increased levels of beneficial agents in an implantable tissue can further improve the implantable tissues and bioprostheses incorporating the tissues through improved mechanical characteristics and longer lifespan.
