Abstract

A conformable surgical tampon for disposition into and removal from an anatomical cavity of a mammalian patient by a doctor to absorb and collect bodily fluids. The tampon comprises an absorbent chassis material and a plurality of spaced apart positioning strings attached to the chassis. The spaced apart positioning strings are operative to selectively position the conformable nasopharyngeal tampon within an anatomical cavity of a patient responsive to manipulation of a positioning string by a surgeon. The tampon is particularly suited for nasopharyngeal surgery.

Claims (26)

1 . A conformable nasopharyngeal tampon for disposition into and removal from an anatomical cavity of a mammalian patient, the tampon comprising:

an absorbent chassis material having two or more polygonal portions, each polygon portion having defined faces; and

a plurality of spaced apart positioning strings attached to the absorbent chassis material, where each positioning string is attached to a respective polygonal portion of the two or more polygonal portions and the positioning strings are operative to selectively position the tampon within an anatomical cavity of a patient responsive to manipulation of the positioning strings.

2 . The tampon according to claim 1 , further comprising an indicium disposed on each of the positioning strings, whereby each of the positioning strings are mutually distinguished by the indicium.

3 . The tampon according to claim 2 , where the indicium is a visual indicium.

4 . The tampon according to claim 1 , the two or more polygonal portions of the tampon including four quadrants, and a positioning string of the plurality of spaced apart positioning strings attached to each one of the four quadrants.

5 . The tampon according to claim 1 , the tampon divisible into at least a front bisection and a rear bisection, the front bisection selectively detachable from the rear bisection via manipulation of one or more of the positioning strings.

6 . The tampon according to claim 5 , where each of the positioning strings comprises a mutually distinguishable indicium.

7 . The tampon according to claim 1 , where the two or more polygonal portions include one or more of parallelopiped and triangular portions.

8 . A compressible tampon configured for disposal into and removal from an anatomical cavity of a patient, the tampon comprising:

an absorbent material having a first uncompressed volume and suitable for being compressed to a second volume less than the first volume when disposed in a hollow deployment tube and returning to the first volume upon expulsion from such a deployment tube, the tampon being sized for insertion into the nasopharyngeal region of a human patient and having a plurality of spaced apart positioning strings attached to the tampon, whereby manipulation of one or more strings of said plurality of spaced apart positioning strings positions the tampon while disposed in the anatomical cavity of the patient,

the absorbent material having two or more polygonal portions, each polygon portion having defined faces, where each positioning string is attached to a respective polygonal portion of the two or more polygonal portions.

9 . The tampon according to claim 8 , the tampon having an exterior surface and further comprising an impermeable barrier disposed on at least a portion of the exterior surface.

10 . The tampon according to claim 8 , the tampon further comprising at least one functional additive.

11 . The tampon according to claim 10 , wherein the functional additive is selected from the group consisting of: a medication, an absorbent gelling material, a luminescent material, an exothermic material, an endothermic material, a pulse oximeter, and combinations thereof.

12 . The tampon according to claim 8 , the tampon having from three to six spaced apart positioning strings.

13 . The tampon according to claim 8 , disposed in a hollow longitudinally extending deployment tube having opposed proximal and distal ends, the tampon being proximate the distal end of the deployment tube and expellable therefrom responsive to manipulation.

14 . The tampon according to claim 8 , the tampon further comprising two or more passages therein for receiving a complementary suction tube, the suction tube having two or more corresponding branches for applying suction and a confluence where the branches are joined into a single main portion connectable to a suction source configured to remove bodily fluids from the patient.

15 . The tampon according to claim 8 , the tampon having at least a first bisection as a first polygonal portion and a second bisection as a second polygonal portion, the first bisection selectively detachable from the second bisection via manipulation of one or more of the positioning strings.

16 . The tampon according to claim 15 , further comprising an indicium disposed on each string of the plurality of spaced apart positioning strings, whereby each string is mutually distinguished by the indicium.

17 . The tampon according to claim 16 , the absorbent material comprising a first zone and a second zone defined by mutually different properties of one or more of density and hydrophilicity.

18 . The tampon according to claim 17 , where the first bisection comprising the first zone and the second bisection comprising the second zone.

19 . The tampon according to claim 18 , where the first bisection has a lesser density than the second bisection.

20 . The tampon according to claim 19 , where the second bisection comprises a diagnostic or therapeutic medication.

21 . The tampon according to claim 15 , the tampon disposed in a kit containing a plurality of mutually different tampons.

22 . The tampon according to claim 8 , where the two or more polygonal portions include one or more of parallelopiped and triangular portions.
