Abstract

A device and method for the continued maintenance of percutaneous sinus tracts between medical catheterization procedures. The device comprises an outer tubular and inner cylindrical members designed to be used with a flexible catheter introduced surgically or with the aid of a trocar device. The method comprises the steps of initially introducing the catheter; sleeving the outer tubular member over the catheter until its outer portion rests against the newly formed sinus tract; completing the desired catheterization procedure; removing the catheter while leaving the outer tubular member in place along the sinus tract; sealing the sinus tract by introduction of the inner cylindrical member into the outer tubular member. As a result the integrity of the sinus tract is maintained for subsequent catheterizations. When a new catheterization is desired the inner cylindrical member is removed; the new catheter is introduced and the members of the invention replaced if subsequent catheterizations are desired. The method can be practiced by skilled technicians or trained family members overcoming the previous need for the attendance of a physician.
