  • Patent number: 6689131
    Abstract: An electrosurgical device for use in surgical procedures is disclosed. The electrosurgical device comprises a main body having a proximal end and a distal end. A heat delivery modality is situated and arranged at the distal end of the main body. A sensor arrangement is also situated and arranged at the distal end of the main body. The heat delivery modality provides thermal energy to a tissue being treated while the sensor arrangement is configured to engage and detect a change in dimension of the tissue being treated. Accordingly, the electrosurgical device of the present disclosure allows a surgeon to precisely achieve the desired amount of dimensional change of the tissue being treated.

  • Patent number: 6679027
    Abstract: A slider device having contoured top and sidewalls is disclosed for use with a resealable package. In a first embodiment, the slider device includes an engagement structure for engaging and interlocking first and second closure profiles of a resealable closure mechanism. The engagement structure includes a first protrusion and a second protrusion depending from the top wall of the slider device for engaging first and second closure profiles of a resealable closure mechanism. The first and second protrusions selectively open and close the resealable closure mechanism as the slider device is moved from a first position to a second position. In a second embodiment, a slider device is disclosed having first and second slide channels that engage first and second closure profiles. The first and second slide channels selectively open and close the resealable closure mechanism as the slider device is moved from a first position to a second position. Methods of assembling and operation are described.

  • Patent number: 6517242
    Abstract: A method of making packages having a reclosable zipper closure encased in a tamper-evident structure, and the packages made thereby. The method includes providing a package having an interior defined by a bottom seam and side seams. The side seams are present as a body seam and a tamper-evident structure seam; there is no side seam present across the zipper closure. The lack of a side seam present across the zipper closure facilitate removal of the tamper-evident structure. A slider device may be present on the packages to facilitate mating and unmating of the zipper closure.
