Method and apparatus to coat a metal implant with electrospun nanofiber matrix

A process providing a method for coating a titanium (Ti) biomedical implant with nanofiber including the steps:

• providing said implant;
• polishing a surface of said implant;
• amending said surface effecting at least one of groves and ridges;
• exposing said surface to plasma O2 in a low pressure reactive ion etching system;
• applying a collagen solution to said surface;
• producing electrospun nanofiber (ENF) made with at least Polycaprolactone (PCL);
• depositing said ENF on said surface positioned within said at least one of grooves and ridges;
• wherein said ENF and collagen (CG) form a nanofiber matrix (NFM), and
• wherein said at least one of grooves and ridges are adapted to at least mitigate physiological loading of said NFM.

A titanium (Ti) biomedical implant produced by a method comprising:

• polishing a surface of said implant;
• amending said surface effecting at least one of groves and ridges at the circumferential direction to increase the surface area of said implant in contact with bone;
• exposing said surface to plasma O2 in a low pressure reactive ion etching system;
• applying a collagen solution to said surface;
• depositing electrospun nanofiber (ENF) made with at least Polycaprolactone (PCL) on to said surface and positioned within said at least one of grooves and ridges;
• wherein said ENF and collagen form a nanofiber matrix (NFM), and
• wherein said at least one of grooves and ridges are adapted to at least mitigate physiological loading of said NFM.
