The packed medical product includes a package defining a cavity with a first compartment and a second compartment separated by a vapor permeable, liquid impermeable barrier. A hydrophilic medical device is contained within the first compartment, and a liquid is contained in the second compartment. The liquid produces a vapor that migrates through the vapor permeable, liquid impermeable barrier into a first compartment. The second compartment has a pressure that is greater than the pressure in the first compartment. ## Claims ### Claim 1 A packaged medical product, comprising: a package defining a cavity, the cavity including a first compartment and a second compartment wherein the first and second compartments are separated by a vapor permeable, liquid impermeable barrier; a hydrophilic medical device contained within the first compartment, the hydrophilic medical device including a hydrophilic material that becomes lubricious when hydrated; a liquid contained in the second compartment, the liquid producing a vapor that migrates through the vapor permeable, liquid impermeable barrier into a first compartment, whereby the vapor hydrates the hydrophilic material; and wherein the second compartment has a pressure that is greater than a pressure in the first compartment. ### Claim 2 (depends on 1) The packaged medical product of claim 1, wherein the second compartment includes a pressure increasing mechanism. ### Claim 3 (depends on 2) The packaged medical product of claim 2, wherein the pressure increasing mechanism comprises components that react with each other to produce a gas. ### Claim 4 (depends on 3) The packaged medical product of claim 3, wherein the components comprise a first component and a second component, and wherein one of the first and second components comprises an acid and the other of the first component and the second component comprises a carbonate. ### Claim 5 (depends on 4) The packaged medical product of claim 4, wherein the acid comprises citric acid and the carbonate comprises sodium bicarbonate. ### Claim 6 (depends on 4) The packaged medical product of claim 4, wherein the first component is in a first solution and the second component is in a second solution, and the first solution and the second solution are mixed to form the liquid. ### Claim 7 (depends on 4) The packaged medical product of claim 4, wherein the first component is in solid form and the second component is in the liquid. ### Claim 8 (depends on 4) The packaged medical product of claim 4, wherein the first component and the second component are in solid form. ### Claim 9 (depends on 4) The packaged medical product of claim 4, wherein the gas comprises one or more of carbon dioxide, nitrogen and oxygen. ### Claim 10 (depends on 1) The packaged medical product of claim 1, wherein the hydrophilic medical device comprises a urinary catheter. ### Claim 11 A method of making a packaged medical product, comprising: placing a hydrophilic medical device in a first compartment of a package; placing a vapor producing liquid in a second compartment of the package, wherein the first compartment and the second compartment are separated by a vapor permeable, liquid impermeable barrier; closing the package; and increasing pressure in the second compartment. ### Claim 12 (depends on 11) The method of claim 11, further including the step of placing a pressure increasing mechanism in the second compartment. ### Claim 13 (depends on 12) The method of claim 12, wherein the pressure increasing mechanism comprises components that react with each other to produce a gas. ### Claim 14 (depends on 13) The method of claim 13, wherein the components comprise a first component and a second component, and wherein one of the first and second components comprises an acid and the other of the first component and the second component comprises a carbonate. ### Claim 15 (depends on 14) The method of claim 14 wherein the acid comprises citric acid and the carbonate comprises sodium bicarbonate. ### Claim 16 (depends on 14) The method of claim 14, wherein the first component is in a first solution and the second component is in a second solution, and the first solution and the second solution are mixed to form the liquid. ### Claim 17 (depends on 14) The method of claim 14, wherein the first component is in solid form and the second component is in the liquid. ### Claim 18 (depends on 14) The method of any claim 14, wherein the first component and second component are in solid form. ### Claim 19 (depends on 13) The method of claim 13, wherein the gas comprises one or more of carbon dioxide, nitrogen and oxygen. ### Claim 20 (depends on 11) The method of claim 11, wherein the hydrophilic medical device comprises a urinary catheter.
