sheath. Each microchannel comprises a porous wall having a thickness of≤ about 100 μm
that is formed from a biocompatible and biodegradable material comprising a polyester
polymer. The polyester polymer may be polycaprolactone, poly (lactic-co-glycolic acid)
polymer, and combinations thereof. The tissue scaffolds have high open volume% enabling
superior (linear and high fidelity) neural tissue growth, while minimizing inflammation near …
