ABSTRACT:
A regeneration chamber for promoting and controlling the growth of biological nerves, including a chamber enclosing and defining a volume in which biological nerves are to be grown, an input port for injecting agents for promoting and controlling the growth of the biological nerves into the chamber, and an output port for receiving agents and biological nerve growth byproducts from the chamber. The input port and chamber have at least one input passage therebetween for the flow of agents from the input port into the chamber and the output port and chamber have at least one output passage therebetween for the flow of agents and biological growth byproducts from the chamber into the output port. The input and output passages are proportioned to reduce increases and decreases in pressure in the chamber and a chamber may have a plurality of input ports and output ports. The passages may be proportioned to the flow characteristics of certain agents, including by selection of the materials for the input and output ports. The regeneration chamber may include a plurality of chamber internal structures, including one or more surface matrices of agents disposed within the chamber or one or more sub-chambers and certain of the sub-chambers may be provided with input and output ports. The chamber internal structures may replicate selected internal biological structures of an organ to be grown.
