    Abstract: A surgical access device is adapted for performing laparoscopic surgical procedures with multiple instruments passing through the surgical access device and through a single incision in the abdominal wall of a patient with the abdominal cavity pressurized with an insufflation gas. The surgical access device is adapted to provide instrument access to the abdominal cavity for surgical procedures while generally maintaining insufflation pressure in the abdominal cavity. The surgical access device comprises an access pad. The access pad comprises a material formed of a mixture comprising a triblock copolymer, an oil, and a foaming agent. The access pad is adapted to be disposed within an incision within an abdominal wall. The access pad has an external flange and an internal flange integrally formed with the access pad. The external flange is adapted to be disposed external to the abdominal wall in an operative position and the internal flange adapted to be disposed internal to the abdominal wall in the operative position. The access pad is configured to be maintained in the operative position and adapted to form a seal with the abdominal wall. A plurality of openings are formed through the access pad between an external surface and an internal surface of the access pad. The plurality of openings when operatively disposed are in communication with the incision and form working channels between a location external to the abdominal wall and a location internal to the abdominal wall. The access pad is adapted to conform to a surface of an instrument inserted through the working channel. At least a portion of the access pad between the external flange and the internal flange and within the incision between an external surface of the abdominal wall and an internal surface of the abdominal wall is adapted to form an instrument seal with the instrument. Locating the access pad within the incision creates a radially compressive force to provide an axial seal between the access pad and the abdominal wall.

    Abstract: A flexible surgery access and instrument management system includes a base unit and an insertion unit. The base unit provides a platform having a connection mechanism to which the insertion unit is attached. The insertion unit includes an elongated conduit having one or more tubes providing instrument passages, and a connection mechanism adapted to selectively couple with the mating connection mechanism provided on the base unit. The elongated conduit of the insertion unit is preferably steerable. One or more flexible instruments may be inserted through the tubes of the elongated conduit, with the proximal ends of the instruments being attached to the base unit such that the user is able to control and manipulate the instruments.

    Abstract: Apparatus & 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.
