1. An ostomy barrier seal comprising:
- an open-ended conical base (1), wherein the conical base (1) from said top opening (3) to said bottom opening (5) is a uniform thickness; and
a flange portion (2) extending radially from said base;
wherein said conical base and said flange portion consists essentially of a thermoplastic elastomer that is strong and elastic and has a tensile strength (break 73°
F./23°
C.) range from 220 psi to 550 psi and a tensile elongation (break 73°
F./23°
C.) range from 650% to 1110%;
wherein said conical base (1) has a top opening (3) and a bottom opening (5) for receiving a stoma of a user, wherein the top opening diameter (9) is between 20 to 80% smaller than the bottom opening diameter (11) and the interior angle between said conical base and said flange is between 20to 40 degrees;
such that the stoma of the user fits through said bottom opening and said top opening expands and constricts to snuggly fit around and seals along the stoma wall without the use of adhesives or glues.

20. A method to reduce the incidence of waste leakage in an ostomy patient comprising the steps of:
-
providing an ostomy barrier seal comprising an open-ended conical base having a top opening and a bottom opening of different diameters at opposite ends of the base for receiving the stoma of a user, wherein the conical base from the top opening to the bottom opening is a uniform thickness; and
a flange portion extending radially from said base;
wherein said open-ended base consists essentially of a thermoplastic elastomer having a tensile strength (break 73°
F./23°
C.) range from 220 psi to 550 psi and a tensile elongation (break 73°
F./23°
C.) range from 650% to 1110%;attaching said barrier seal to a barrier; applying said barrier over the stoma of a patient such that said barrier seal expands and constricts to fit snuggly over the stoma and without glue or adhesive forms a fluid tight seal along the stoma wall; and attaching an ostomy pouch to said barrier;
wherein said barrier seal reduces and prevents waste leakage. - View Dependent Claims (21, 22, 23, 24)
