Abstract
Ready to use packaged medical products that include hydrated hydrophilic medical devices and methods of making the same. 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.
Claims20
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.
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.
