Claims
- 1. A cell containment device comprising:
a permeable membrane delimiting a space for containing cells therein; a closure region comprising a thermoplastic polymer in association with the permeable membrane and means for placing cells in said space through said closure region; wherein said closure region is closeable with a wet seal.
- 2. A containment device comprising:
a membrane; a polymer in communication with the membrane; and at least one closure, the closure created by applying heat to a portion of the membrane and to a portion of the polymer after wetting the membrane with a liquid.
- 3. A device according to claim 2, further comprising a cell suspension within a space enclosed by the membrane.
- 4. A device according to claim 2, further comprising a drug formulation within a space enclosed by the membrane.
- 5. A device according to claim 2, wherein the membrane includes a polymer membrane.
- 6. A device according to claim 2, wherein the membrane includes a porous PTFE membrane.
- 7. A device according to claim 2, wherein the membrane substantially surrounds the polymer.
- 8. A device according to claim 2, wherein the membrane is substantially tubular.
- 9. A device according to claim 2, further comprising a closure on a first end of the tubular membrane and the closure created by applying heat is on a second end of the tubular membrane.
- 10. A device according to claim 2, wherein the polymer includes FEP.
- 11. A device according to claim 2, wherein the polymer is distinct from the membrane.
- 12. A device according to claim 2, wherein the closure is substantially part of the polymer.
- 13. A device according to claim 2, wherein the closure is substantially separate from the membrane.
