ABSTRACT:
A grommet positioning device 10 includes a positioning member 16, such as a sheath 28, carrying an elastic anchor, fastener or grommet 14 thereon. The grommet 14 is preferably composed of silicone and has a predefined, unstressed interior diameter. The positioning member 16 includes a portion 25 in contact with the grommet, the portion 25 having an outer diameter at least equal to the predefined, unstressed interior diameter of the grommet 14. The positioning member 16 is capable of being split or torn apart along at least the portion 25, so as to release the grommet 14 from the member 16 and allow it to be fixed in position along an object such as a catheter 12. The interior diameter of the grommet 14 is chosen to preclude closure or blockage of the catheter 12 when the grommet 14 is positioned on it. The positioning member 16 is preferably configured as a sheath 28 composed of molecular oriented PTFE, capable of being split along its entire length, and includes pull tabs 46 for causing such splitting. The grommet 14 can include shoulders 44 for assisting securement of the grommet 14 to its environment of use as desired, for example, adjacent to the body 20 of a patient being catheterized. A catheterization apparatus 56 includes a catheter 12 carrying the grommet positioning device 10 on it.
