A seal and a mask having a seal adapted for confronting engagement with a surface of a user to form an interface therewith. The seal includes a first portion defined by a gel substance and a second portion associated with the first portion. The second portion includes a selectively formable substance adapted to be molded from a first pattern into a second pattern and to retain the second pattern responsive to being so molded. The seal and mask having the seal is tailored to patient by causing the formable portion of the seal to be placed in a malleable state, applying the seal to the patient while the formable portion is in the malleable state, and causing the formable portion to be placed in a fixed state to retain a shape generally conforming to the portion of the patient underlying the seal.

1. A method of interfacing a patient with an external device, comprising:providing an external device to be interfaced with a patient; providing a seal having a first surface operatively coupled to the external device and a second surface adapted for confronting engagement with an external surface of a patient to form an interface therewith, wherein the seal includes a selectively formable portion having a first pattern that is adapted to be molded into a second pattern and to retain the second pattern responsive to being so molded, and wherein the selectively formable portion includes a combination of a gel substance and a selectively formable stiffening agent; and applying the seal to such an external surface of a patient by applying a compressive force on the formable portion of the seal so that the formable portion takes on the second pattern generally conforming to contours of a portion of such a patient underlying the seal, wherein the formable portion retains the second pattern even after the compressive force is removed from the formable portion. 2. A method according to claim 1, wherein the seal further comprises a first portion defined by a gel substance substantially integrally associated with said selectively formable portion, said first portion being arranged relative to the selectively formable portion such that said first portion is disposed between a patient and the selectively formable portion responsive to said external device being dispose on such a patient.3. A method according to claim 1, wherein the selectively formable stiffening agent is a thermally activated material, and further comprising enabling the formable portion of the seal to be molded from the first pattern to the second pattern by heating the formable portion to a temperature sufficient to activate the thermally activated material.4. A method according to claim 3, wherein heating the formable portion of the seal includes placing said seal in a heated fluid for a first predetermined period of time and, thereafter, quenching said seal in a reduced temperature fluid for second predetermined period of time so that an exterior surface of said seal has a temperature suitable to be applied to a human without substantial discomfort.5. A method according to claim 1, further comprising retaining the seal on such a patient while the formable portion from the first pattern to the second pattern.6. A method according to claim 1, further comprising providing a retaining member proximate to said seal to prevent movement of the seal.
