    摘要： Fibrous connective tissue for surgical implantation is made substantially antigen-free by contact with one or more extraction agents. Solutions or mixtures of molecules having bipolar regions act as antigen removing permeation enhancers. Cationic, anionic, non-ionic or amphoteric surfactants are suitable bipolar permeation enhancers. One or more extraction agents can be combined to form extraction mixtures.

    摘要： The present invention provides a plasticized dehydrated or freeze-dried bone and/or soft tissue product that does not require special conditions of storage, for example refrigeration or freezing, exhibits materials properties that approximate those properties present in normal hydrated tissue, is not brittle, does not necessitate rehydration prior to clinical implantation and is not a potential source for disease transmission. The invention replaces water in the molecular structure of the bone or soft tissue matrix with one or more plasticizers allowing for dehydration of the tissue, yet not resulting in an increase in brittleness of the plasticized product, and resulting in compressive and/or tensile properties similar to those of normal hydrated bone. Replacement of the chemical plasticizers by water prior to implantation is not required and thus, the dehydrated bone or soft tissue plasticized product can be placed directly into an implant site without significant preparation in the operating room.

    摘要： A tissue biopsy cell suspender device includes a receptacle having a sealable opening. The receptacle contains a sufficient quantity of an aqueous medium to support an enzymatic dissociation of cells from a tissue biopsy sample. The device has a removable closure with a first sealing position and a second sealing position for sealing the opening in the receptacle. The device further includes a frangible container having a sufficient quantity of an enzyme therein to dissociate cells from the tissue biopsy sample. The frangible container is covered with a membrane that is permeable to water and to the enzyme. The frangible container is disposed within the receptacle so that the container is intact when the closure is in the first sealing position and the container is breached when the closure is in the second sealing position. When the frangible container is breached, the enzyme is released to permeate into the medium and for dissociation of the cells from the tissue sample.
