Abstract
This invention relates generally to an implantable containment apparatus made of selectively permeable material. In particular, the implantable containment apparatus is used to contain a therapeutical device, such as a drug delivery device, a cell encapsulation device, or a gene therapy device. A therapeutical device can be easily placed and replaced in an apparatus of the present invention without damaging tissues associated with the selectively permeable material of the apparatus.
Claims6
A method of repeatedly filling and emptying an implantable containment apparatus tube with a therapeutical device, which comprises:
- (a) providing an implantable containment apparatus in the form of a tube comprised of a selectively permeable polymeric material having an exterior surface, an interior surface defining a luminal space of substantially uniform diameter, and an access means at each end of the tube that permits access to the luminal space of the tube;
- (b) opening both access means of the implantable containment apparatus tube to access the luminal space of the tube;
- (c) providing a means of establishing and maintaining a fluid stream through the luminal space of the implantable containment apparatus tube;
- (d) connecting the fluid stream means of step (c) to one of the opened access means of the implantable containment apparatus tube;
- (e) establishing a fluid stream through the luminal space of the implantable containment apparatus tube with the fluid stream means of step (c);
- (f) entraining a therapeutical device in the fluid stream;
- (g) delivering the entrained therapeutical device into the luminal space of the implantable containment apparatus with the fluid stream;
- (h) discontinuing the fluid stream;
- (i) disconnecting the fluid stream means of step (c) from the opened access means;
- (j) closing both access means of the implantable containment apparatus to contain the therapeutical device within the luminal space of the implantable containment apparatus;
- (k) providing a means of establishing and maintaining a fluid stream around the therapeutical device and through the luminal space of the implantable containment apparatus;
- (l) opening both access means of the implantable containment apparatus;
- (m) connecting the fluid stream means of step (k) to one of the opened access means of the implantable containment apparatus;
- (n) establishing a fluid stream around the therapeutical device and through the luminal space of the implantable containment apparatus tube to entrain the therapeutical device in the fluid stream;
- (o) removing the entrained therapeutical device from the luminal space of the implantable containment apparatus with the fluid stream of step (n);
- and
- (p) repeating steps (c) through (o) as desired.
