  • Tissue retrieval system
    Patent number: 8721658
    Abstract: The tissue retrieval system deploys a tissue bag at the surgical site. The bag is supported by the system as tissue is placed within the bag and is closed to isolate the collected tissue and allow the bag and collected tissue to be removed from the body. The bag can be reopened and re-closed as desired through use of a guide bead and cord. The bead also facilitates removal of the collected tissue.

  • System and method for actuating a laparoscopic surgical instrument
    Patent number: 8114120
    Abstract: A surgical instrument can include tips and an actuation rod having a pin and slot design where the driving slots are moved from the tips to the actuation rod in one aspect of the invention. As a result, the back end of each blade or tip can be dramatically reduced in area so that during full deflection, very little or no part of the blade or tip extends beyond the outside diameter of the shaft. In addition, the depth of each slot can be varied such that during actuation, increased tension can be put on the blades or tips throughout the cut.
