Patent ID: 7887548

Claim:
A surgical device comprising: an inner tubular body having a discontinuous wall surrounding a circular bore, the wall having a cylindrical proximal portion and a cylindrical distal portion, the wall forming a fenestration along the distal portion which extends to a distal end of the inner tubular body, the distal portion having a smaller diameter than the proximal portion; an outer tubular body for placement around the inner tubular body, the outer tubular body having a discontinuous wall, the wall having a cylindrical proximal portion and a cylindrical distal portion, the wall forming a fenestration along the distal portion which extends to a distal end of the outer tubular body, the distal end of the outer tubular body having grooves to secure the device to a surgical site in a human or animal, the distal portion having a smaller diameter than the proximal portion; the inner tubular body and the outer tubular body rotatable with respect to each other; the inner tubular body including a recess around an outer surface of the inner tubular body, the recess adapted to receive a male protrusion extending from an inner surface of the outer tubular body; the fenestrations alignable such that when the inner tubular body is in a first position with respect to the outer tubular body, the fenestrations align to provide a passage through the wall of the surgical device, and when the inner tubular body and outer tubular body are rotated with respect to each other to a second position, the fenestrations oppose each other to form a generally tubular wall along the length of the surgical device.
