    Abstract: A surgical access device assembly includes a cannula hub and a cannula tube. The cannula tube extends distally from the cannula hub along a longitudinal axis. The cannula tube defines a working channel. The cannula tube includes a tissue engagement feature and a balancing feature. The balancing feature is configured to promote lateral stability of the cannula tube and the cannula hub relative to the body cavity wall of the patient. The balancing feature includes a proximal portion of the cannula tube having a first wall thickness. The balancing feature also includes a distal portion of the cannula tube having a second wall thickness that is greater than the first wall thickness. At least a portion of the proximal portion is proximal relative to the tissue engagement feature. At least a portion of the distal portion is distal relative to the tissue engagement feature.

    Abstract: A surgical system for use in establishing and maintaining an opening to an anatomical space of a body, the system comprising an obturator assembly having a cutting portion at a distal end and a cannula, the cannula being detachably coupled to the cutting portion and deployable into the anatomical space of a patient, the cannula comprises a locking portion, and a lengthwise extendable body; a valve assembly comprising a passage for receiving the cannula, a first end for coupling to a fluid extraction device and a second end for placement external and adjacent the anatomical space; a base comprising a plate for placement on a patient external and adjacent the anatomical space, the plate has an aperture configured for receiving the obturator assembly and coupling means located about the aperture for coupling with the valve assembly; and wherein, in use, the locking portion of the cannula is configured to be retained in the valve assembly with the extendable body extended into the anatomical space to facilitate a path for fluid extraction, and wherein the cannula comprises means for retaining the cannula in its extended state.

    Abstract: An access catheter provides access for a large bore stiff therapeutic catheter across the atrial septum from above via the superior vena cava. The access catheter has an expandable member that direct a delivery tube outwards in a radial direction to place a delivery tube opening into direct contact with the fossa ovalis. The braided expandable member allows blood flow to pass when it is expanded; the expandable member provides support against the opposite wall of the right atrium. A hollow dilator tube enters the delivery tube to form a tenting shape to the fossa and a guidewire is passed across the fossa ovalis. Standard procedure allows delivery of the therapeutic catheter over the guidewire.
