Abstract

An adjustable shape abscess irrigation device includes a first tube that is slidably associated with a second tube. The irrigation device includes a retainer that defines a variable shape diameter. The diameter of the retainer is selectively adjustable by the relative positioning of the first tube and the second tube such that, once placed relative to an abscess, the shape of the device can be manipulated to allow desired drainage of irrigation and abscess fluids beyond the confines of the abscess. Upon adequate drainage of the abscess, the cross-section shape of the retainer can be reduced to facilitate more comfortable and less detrimental removal of the device from the patient. Preferably, the irrigation device is formed via one or multi-shot injection molding and is formed of more than material.

Claims

1. A method of forming an anatomical drainage tool comprising:

positioning a first tube concentrically with respect to a second tube; and

connecting the first tube to the second tube with a living hinge such that a relative positioning of the first tube to the second tube manipulates a radial diameter of the drainage tool via movement of the living hinge.

2. The method of claim 1 wherein manipulating the radial diameter of the drainage tool is performed by at least one of longitudinally translating and rotationally translating the second tube relative to the first tube.

3. The method of claim 1 further comprising forming the living hinge with a plurality of members that each extend in different radial directions from a longitudinal axis of the first tube.

4. The method of claim 3 further comprising forming a vent in at least one of the first tube the second tube, and the living hinge.

5. The method of claim 4 further comprising forming the vent with a plurality of openings and directing each opening in a different direction.

6. The method of claim 1 further comprising forming the living hinge with a material that is more pliable than at least one of the first tube and the second tube.

7. The method of claim 1 further comprising injection molding the first tube, the second tube and the living hinge.

8. An abscess drainage tool comprising:

a first tube and a second tube slidably associated with one another;

a first fluid path formed through the first tube;

a retainer connecting the first tube to the second tube, the retainer having a variable diameter such that a relative orientation of the first tube and the second tube defines an instantaneous diameter of the retainer; and

a second fluid path formed at least one of between the first tube and the second tube and between the second tube and adjacent anatomy such that fluid introduced into an abscess via one of the first fluid path and the second fluid path discharges from the abscess via the other of the first fluid path and the second fluid path.

9. The abscess drainage tool of claim 8 wherein the retainer further comprises as least one living hinge whose orientation is directly dependant on an orientation of the first tube relative to the second tube.

10. The abscess drainage tool of claim 9 wherein the orientation of the living hinge is determined by at least one of a radial orientation and a longitudinal orientation of the first tube relative to the second tube.
