    摘要： Apparatus and methods for optimizing anchoring force are described herein. In securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable arms configured to minimize contact area between the anchor and tissue. When the anchor is in its expanded configuration, a load is applied to the anchor until it is optimally configured to accommodate a range of deflections while the anchor itself exerts a substantially constant force against the tissue. Various devices, e.g., stops, spring members, fuses, strain gauges, etc., can be used to indicate when the anchor has been deflected to a predetermined level within the optimal range. Moreover, other factors to affect the anchor characteristics include, e.g., varying the number of arms or struts of the anchor, positioning of the arms, configuration of the arms, the length of the collars, etc.

    摘要： A surgical access device includes an access seal comprising an ultra gel elastomeric material formed of a mixture comprising a triblock copolymer and an oil. The access seal is adapted to be disposed relative to the abdominal wall. At least one access channel is formed through the elastomeric material between a proximal portion and a distal portion of the access seal. The access channel when operatively disposed forms at least a portion of a working channel between a location external to the abdominal wall and a location internal to the abdominal wall. The elastomeric material of the access seal is adapted to conform to a surface of an instrument inserted through the working channel to provide instrument access to the abdominal cavity while maintaining insufflation pressure in the abdominal cavity. The access channel is configured to self seal in the absence of any instrument extending through the access channel.

    摘要： Endoluminal instrument management systems are described herein which allow one or more operators to manage multiple different instruments utilized in endoluminal procedures. Responsibility for instrumentation management between one or more operators may be configured such that a first set of instruments is controlled by a primary operator and a second set of instruments is controlled by a secondary operator. The division of instrumentation may be facilitated by the use of separated instrumentation platforms or a single platform which separates each instrument for use by the primary operator. Such platforms may be configured as trays, instrument support arms, multi-instrument channels, as well as rigidized portions of instruments to facilitate its handling, among others.

    摘要： A surgical access device includes a single valve forming a seal with the body wall and providing an access channel into a body cavity. The valve has properties for creating a zero-seal in the absence of an instrument and an instrument seal with instruments. The valve can include a gel comprised of an elastomer and oil providing elongation greater than 1000 percent and durometer less than 5 Shore A. The single valve can be used as a hand port where the instrument comprises the arm of a surgeon. A method for making the surgical access device includes combining a gelling agent with oil, preferably in a molding process. A method for using the device includes creating an opening with the instrument. An organ can be removed from the body cavity through the single valve to create an organ seal while the organ is addressed externally of the body cavity.
