ABSTRACT:
An assembly for use in drainage of an abscess comprises an outer tubular member provided in a distal end portion with a plurality of longitudinal slits. The distal end portion of the tubular member has a spring bias tending to form the distal end portion into a substantially spherical expanded configuration to anchor the distal end portion of the tubular member in an abscess. An inner tubular member or obturator is inserted into the outer tubular member and has a distal end provided with a cutting edge projecting from the outer tubular member. Locking components on the obturator and the outer tubular member serve to maintain the latter in a stretched out cylindrical configuration enabling insertion of the distal end portion into an abscess.
