Patent ID: 8551390

Claim:
An electrospinning apparatus, comprising a device that a fiber is drawn from, wherein the tip of the device from where the fiber is drawn is at a first potential, and a structure that includes a plurality of conductive probes, wherein each probe has a distal end, wherein a portion of each probe extends from a non-conductive surface of the structure, wherein a first set of the distal ends are recessed relative to a second set of distal ends, wherein the first set and the set of distal ends form a first boundary of a target volume, wherein a second boundary of the target volume is not bound by the distal ends of the plurality of the probes, wherein the device is positioned adjacent the second boundary, wherein the conductive probes are at second potential, wherein there is a potential difference between the first potential and the second potential that causes the fiber to be directed to the target volume through the second boundary.
