Novel biological implant compositions, implants and methods

A method of surgery on a human patient, comprising:

• providing an allograft unitary implant consisting essentially of human tissue components in a compressed dehydrated form, and
• providing a minimally invasive access portal into a surgical site within said human patient, and
• passing said implant through said minimally invasive access portal, and
• providing a hydration fluid in contact with said implant, wherein
• said implant expands following contact with said hydration fluid to create an expanded implant, and
• positioning or fixing said implant in place at said surgical site to create a fixed implant,
• wherein, said expanded implant has a fixed unitary shape which is larger than that which could have passed through said portal.

A biological graft, consisting essentially of human tissue components comprising;

• a bone block of cortical bone, cancellous bone or both, said bone block having at least one porous or semi-porous surface;
• and
• a molded tissue component comprising demineralized bone matrix (DBM) and a human tissue slurry;
• wherein said molded tissue component is integrated into said porous or semi-porous surface of said bone block.
