Abstract

An ostomy cartridge for use in host device in a mammal includes a body formed at elastomeric partially of polymeric material and a stem. The stem is secured to the body and is operable to permit insertion of the body into the host device and removal of the body from the host device. The stem and the body cooperate with one another and the host device to prevent flow of liquid and solid waste through the host device to the exterior of the mammal with which the host device is associated.

21. An ostomy cartridge as set forth in claim 18, wherein the foam material includes hydrophilic foam.

22. An ostomy cartridge as set forth in claim 21, wherein the body has a proximal end impermeable to solid waste transfer therethrough.

23. An ostomy cartridge for use with a host device associated with a mammal, said cartridge including:

a generally cylindrical body formed at least partially of polymeric material; and

a stem secured to the body and operable to permit insertion of the body into the host device, which is disposed within the user'"'"'s body during use, and removal of the body from the host device, said stem and said body cooperating with one another and associated with thye host device to prevent flow of liquid and solid waste through the host device to the exterior of the mammal with which the host device is associated wherein the stem includes protruding members (12c, 12d) to provide support for the host device.

24. An ostomy cartridge as set forth in claim 23, wherein the body includes a portion comprising polymeric team.

25. An ostomy cartridge as set forth in claim 24, wherein at least a portion of the polymeric foam is open cell form.

26. An ostomy cartridge as set forth in claim 24, wherein at least a portion of the polymeric foam is closed cell foam.
