Abstract
An orifice introducer device for introducing, e.g., a surgical device, into, e.g., an orifice of a body, includes a tubular member having a distal end and a proximal end. The distal end is adjustable between a first position for insertion into an orifice and a second position once inserted into the orifice. Alternatively, the orifice introducer device includes a distal portion having a proximal end configured to be detachably secured to the distal end of the tubular member. The distal portion is selectively detachable when the orifice introducer device is positioned in the orifice.
