1. An orifice introducer device, comprising:
- a tubular member having a distal end and a proximal end, the tubular member including at least one slit, seam, or perforation longitudinally extending from the distal end, the at least one slit, seam, or perforation radially opposed to any other slit, seam, or perforation which also extends longitudinally from the distal end;
a diameter of the distal end being adjustable between a first position for insertion into an orifice and a second position once inserted into the orifice, the diameter of the distal end adjusted to the second position relative to the first position by manipulation of the at least one slit, seam or perforation,wherein the at least one slit, seam, or perforation extends longitudinally from the distal end of the tubular member in both the first and second positions.

Abstract
An orifice introducer device for introducing, for example a surgical device, into, for example 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.
