Abstract

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.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 230 words
A regeneration chamber for promoting and controlling the growth of nerve tissues, comprising: a chamber enclosing and defining a volume in which nerve tissues are to be grown, at least one input port for injecting at least one agent for promoting and controlling the growth of the nerve tissues into the chamber, and at least one output port for removing the at least one agent and nerve tissue growth byproducts from the chamber, the at least one input port and the chamber having at least one input passage there between for the flow of the at least one agent from the at least one input port into the chamber, and the at least one output port and the chamber having at least one output passage there between for the flow of the at least one agent and the nerve tissue growth byproducts from the chamber into the at least output port, wherein the at least one input port and the at least one output port are operative during the growth of the nerve tissue for the flow of the at least one agent from the at least one input port into the chamber and the flow of the at least one agent and the nerve tissue growth byproducts from the chamber and into the at least one output port at any selectable time during the growth of the nerve tissue.
Claim 2
Dependent Claim 230 words
A regeneration chamber for promoting and controlling the growth of nerve tissues, comprising: a chamber enclosing and defining a volume in which nerve tissues are to be grown, at least one input port for injecting at least one agent for promoting and controlling the growth of the nerve tissues into the chamber, and at least one output port for removing the at least one agent and nerve tissue growth byproducts from the chamber, the at least one input port and the chamber having at least one input passage there between for the flow of the at least one agent from the at least one input port into the chamber, and the at least one output port and the chamber having at least one output passage there between for the flow of the at least one agent and the nerve tissue growth byproducts from the chamber into the at least output port, wherein the at least one input port and the at least one output port are operative during the growth of the nerve tissue for the flow of the at least one agent from the at least one input port into the chamber and the flow of the at least one agent and the nerve tissue growth byproducts from the chamber and into the at least one output port at any selectable time during the growth of the nerve tissue.
Claim 3
Dependent Claim 13 words
The regeneration chamber of claim 1, further including a plurality of input ports.
Claim 4
Dependent Claim 13 words
The regeneration chamber of claim 1, further including a plurality of output ports.
Claim 5
Dependent Claim 33 words
The regeneration chamber of claim 1 wherein the chamber further comprises a plurality of chamber internal structures, the chamber internal structures comprise one or more surface matrices of agents disposed within the chamber.
Claim 6
Dependent Claim 105 words
The generation chamber of claim 1 wherein the the at least one agent is selected from the group of agents including embryonic tissue cells, fluid from embryonic tissue cells, Nerve Growth Factor (NGF), collagen, laminin, and fibronectin, target derived neuronotropic factors, Schwann cells, glial cells, dorsal root ganglia cells, neural crest cells, ciliary neuronotropic factor (CNTF), motor nerve growth factor (MNGF), neural cell adhesion molecules (N-CAM), N-Cadherin, fibrin, estrogen, testosterone, thyroid hormone, corticotropin, and insulin, catalase, acidic fibroblast growth factor (aFGF), basic fibroblast growth factor (bFGF), forskolin, glia-derived protease inhibitor (GdNPF), ganglioside GM-1, insulin-like growth factor, isaxonine, leupeptin, muscle basal lamina pyronin, and Hyaluronic Acid.
Claim 7
Dependent Claim 16 words
The generation chamber of claim 1 wherein the nerve tisues are the tissues of peripheral nerves.
