TRANSCUTANEOUS DEVICES HAVING NUERAL INTERFACE

摘要

A transcutaneous implant constitutes proximal partially external section; a collar section, integrally dependent from the external section, the collar section having a microtextured surface constituting a microgeometric, repetitive surface pattern, in a form of multiplicity of alternating ridges and grooves, each having an established width in a range of about 2 to about 25 microns, and an established depth in a like range; an anchor-like distal section, integrally dependent from the collar section, for implantation into a bone segment to be stabilized during a medically advantageous period of time. The surface pattern defines a guide at tissue, cellular and molecular levels for a preferential promotion of rate, orientation and direction of growth of colonies of cells which are in contact with the pattern.
