摘要：
Medical systems, devices and methods are provided for accessing a bodily opening that, among other things, are safe and reliable, and facilitate manipulation of a medical instrument. The medical access device generally includes an elongated flexible sheath and an expandable frame connected to the distal end of the flexible sheath. The sheath and expandable frame are operable between expanded and collapsed configurations to provide a pathway from a natural orifice to the bodily opening.
