Packaged hydrophilic medical products that are hydrated within the package and methods of making the same
Ready to use packaged medical products that include hydrated hydrophilic medical devices and methods of making the same.
1 . A packaged medical product, comprising:
a package defining a cavity;
a hydrophilic medical device contained within the cavity; and
a sachet contained within the cavity; and
a hydration liquid within the sachet, the hydration liquid being supersaturated with a dissolved gas, wherein the sachet includes a weak portion configured to burst, and wherein upon exposure to sterilizing radiation, dissolved gas is released from the hydration liquid to increase pressure within the sachet, thereby bursting the weak portion of the sachet and releasing the hydration liquid from the sachet.
2 . The packaged medical product of claim 1 , wherein the sachet is configured to burst upon exposure to E-beam radiation.
3 . The packaged medical product of claim 1 , wherein the dissolved gas comprises at least one of carbon dioxide and nitrogen.
4 . The packaged medical product of claim 1 , wherein the weak portion comprises at least one of a weak seal and a partial cut in a material of the sachet.
5 . The packaged medical product of claim 1 , wherein the hydrophilic medical device comprises a urinary catheter.
6 . The packaged medical product of claim 1 , wherein the sachet is made from a liquid impermeable material.
7 . The packaged medical product of claim 6 , wherein the material comprises a polymer/metal laminate.
8 . The packaged medical product of claim 1 , wherein the hydration liquid contains a foaming agent.
9 . A method of making a packaged medical product, comprising:
placing a hydrophilic medical device within a cavity of a package;
placing a liquid filled sachet within the cavity of the package, wherein the liquid filled sachet contains a hydration liquid and the hydration liquid includes a dissolved gas;
closing the package; and
exposing the package to radiation to heat the hydration liquid and release the dissolved gas from the hydration liquid, thereby increasing pressure within the sachet to burst the sachet and release the hydration liquid.
10 . The method of claim 9 , wherein exposing the package to radiation comprises exposing the package to E-Beam radiation.
11 . The method of claim 9 , wherein the dissolved gas comprises at least one of carbon dioxide and nitrogen.
12 . The method of claim 9 , wherein the hydration liquid is supersaturated with the dissolved gas.
13 . The method of claim 9 , wherein the sachet includes a weakened portion that is configured to open.
14 . The method of claim 13 , wherein the weakened portion comprises at least one of a weak seal and a partial cut in a material of the sachet.
15 . The method of claim 9 , wherein the hydrophilic medical device comprises a urinary catheter.
16 . A packaged medical product, comprising:
a sleeve;
a hydrophilic medical device contained within the sleeve;
a sachet contained within the sleeve; and
a hydration liquid within the sachet, the hydration liquid being supersaturated with a dissolved gas, wherein the sachet includes a weak portion configured to burst, and wherein upon exposure to sterilizing radiation, dissolved gas is released from the hydration liquid to increase pressure within the sachet, thereby bursting the weak portion of the sachet and releasing the hydration liquid from the sachet.
17 . The packaged medical product of claim 16 , wherein the dissolved gas comprises at least one of carbon dioxide and nitrogen.
18 . The packaged medical product of claim 16 , wherein the weak portion comprises at least one of a weak seal and a partial cut in a material of the sachet.
19 . The packaged medical product of claim 16 , wherein the sachet is made from a liquid impermeable material.
20 . The packaged medical product of claim 16 , wherein the hydration liquid contains a foaming agent.
