1. An access port for surgical procedures, comprising;

  • an elongated tubular sheath having a proximal end, a distal end, and a lumen extending therebetween;

    an expandable element disposed around the distal end of the sheath having a compressed state and an expanded state, wherein the expandable element is operable to be positioned within a wall of an organ while in the compressed state, and wherein the expandable element is further operable to be deployed once it is within the organ to convert to the expanded state;

    a stop-grip mechanism disposed on the exterior of the sheath proximal to the expandable element including a grip member positioned distally and movable over the sheath and adapted to apply a biased resistive force across the organ wall in opposition to the expandable element in its expanded state; and

    a device valve connected to the proximal end of the sheath to allow devices to be placed and removed through the sheath while minimizing blood loss.
