Abstract: A fixing device for suturing of blood vessels is provided, which includes a connecting rod, a first clamping member, a second clamping member, a first extension tube and a second extension tube. One end of the first clamping member is disposed on the connecting rod, and the other end of the first clamping member has a first clamping head. One end of the second clamping member is disposed on the connecting rod, and the other end of the second clamping member has a second clamping head. The first extension tube is disposed on an inner side of the first clamping head. The second extension tube is disposed on an inner side of the second clamping head and opposite to the first extension tube, wherein a relative position of the first extension tube and the second extension tube is adjustable.

Abstract: A retinal prosthesis including a microelectrode array, a polymer layer and a layer of bioactive molecule is provided. The microelectrode includes a plurality of microelectrodes. The polymer layer partly encapsulates the microelectrode array, in which the microelectrodes are exposed on the surface of the polymer layer. The layer of bioactive molecules is immobilized on the surface of the microelectrode.

Abstract: The present invention relates to a device for directing and accelerating the growth of neuronal axon or neurite. The invention accelerates the growth speed of axon of nerve cells by using a substrate configured with a discontinuous micropattern of neuronal path-finding molecules or material thereon. The invention can reduce the connection or regeneration time of neural network. The present invention also discloses a micro-contact printing method for producing the device.

Abstract: The invention provides a conditioned medium that enhances the survival and/or proliferation of Schwann cells in cell culture, and a cell line useful for production of such medium. The cell line used in the invention is a differentiated NTera2/D1 (NT2) cell line.
