Abstract

The invention relates to a removable anchoring element (3) for an implantable microcontact foil (2) used as a neuroimplant, especially for retina implants. The anchoring head rises above the surface of the implant, for fixing purposes, and the fixing device can be removed during the re-explantation or anchoring process by pulling the implant foil (2) beneath the anchoring head.

Claims

1-3. -3. (canceled)

4. A removable fixing device for implantable microcontact foils as neuroimplants, comprising:

an anchoring head that extends beyond an inplant on a side thereof that faces away from tissue that is to receive said implant for a fixing purpose, wherein such fixing can be released for a re-explantation by a pulling of a microcontact foil out from beneath said anchoring head.

5. A removable fixing device for implantable microcontact foils as neuroimplants, comprising:

an anchoring head that extends beyond an inplant surface for a fixing purpose, wherein for releasing such fixing, said anchoring head can be rotated, swiveled, folded or pulled.

6. A removable fixing head for implantable microcontact foils as neuroimplants, comprising:

an anchoring head, and

anchoring structure protruding through tissue that is to receive an implant, wherein said anchoring head is removably connectable with said anchoring structure.
