An implant for bridging a gap in a severed spinal cord or nerve and for promoting nerve regeneration has a matrix comprising a biocompatible, biodegradable, polymeric material. The matrix has a proximal end for connection to a first end of severed spinal cord and a distal end for connection to a second end of severed spinal cord. The matrix includes internal guidance channels extending between the proximal end and the distal end to facilitate rejoining of the first end and the second end of the severed spinal cord. A bioactive agent may be dispersed in the matrix, or disposed in the channels, or included within microspheres in the channels. The channels may be arranged such that guidance channels correspond to spinal cord tracts. Alternatively, guidance channels may be spaced apart at the proximal end of the matrix and converge inward toward the axis of the matrix at the distal end.

A coupling structure for coupling optical radiation, i.e., light, between an optical fibre and an optical device, e.g., a laser diode or a photodiode. The coupling structure has an optical through-via which guides the optical radiation to or from the optical fibre. Light exiting the fibre travels through a guidance channel so it remains substantially confined to a narrow optical path that mimics the fibre core. Conversely, light enters the fibre after having traveled through the guidance channel. The guidance channel has a first core region, the “channel core”, having first refractive index surrounded by a second region, the “channel cladding” having a second refractive index smaller than the first refractive index. The coupling structure, including the guidance channel, is preferably made of semiconductor-based material, more preferably of silicon-based material. The guidance channel is preferably silicon oxide. The coupling structure further has a fibre drive-in element, which facilitates insertion and alignment of the optical fibre to the guidance channel.

A guidance channel radiating from each side of clip holding chamber centered on a flat plate. A prying tool slideably and rotatably held within each guidance channel by a spring strip. A split ring held snugly within the holding chamber. The tool tips are forced between the split ring coils, which are separated further by simultaneous rotation of the prying tool handles 90-degrees in opposite clock directions. A pellet placed inside folded bag material forms a bump. The material with bump is placed between the separated coils into the split ring interior. Reverse 90-degree handle rotation partly closes the coils around the bump. Withdrawing the prying tools completely allows the coils to fully close, capturing the pellet-containing material. Tool stops prevent the tool tips from entering the split ring interior too far into or away from the clip holding chamber. Suspension of the tool and bags facilitates production.
